What are /r/roasting's favorite Products & Services?

From 3.5 billion Reddit comments

It doesn't matter which grinder you use as long as the grind is consistent and calibrated. The easiest way to check to see where your grinder stands is to get some #10, #20, #30 mesh metal screening (or you can buy lab sieves like this) and sieve the grounds. You are looking for the bulk of the percentage weight of the sample trapped on the #30 screen (10 is the largest holes).

If you don't have a lot of powder or grounds passing through the #30, then your grinder is just fine.

Also bear in mind that it makes no difference what the reputation or cost of the high falutin' lab grinder is, if you don't clean and maintain it, it will work just as horribly as a crappy Black and Decker.

Don’t use a CharBroil rotisserie motor. Much too slow and will result in an uneven roast. I bought this one that allows up to 55 rpm variable: Tritogenia New Variable Speed... https://www.amazon.com/dp/B07GC4W1JN?ref=ppx_pop_mob_ap_share

I’m using the spit rod from the CharBroil one I bought. Had to file the holes square and larger but that was easy.

https://www.amazon.ca/dp/B08B4KHZTM/ref=cm_sw_r_cp_apa_glt_i_28XFKR3CPSJQC55C2R84, there basically all the same but this one is on sale . Which ever u buy make sure too get the double layer definitely Worth it for chaff seperation 🤗 Cheers

It's a great machine. The extension tube from Sweet Marias will allow you to roast larger quantities more evenly. Also buy a digital thermometer with K type probe. https://www.amazon.com/TP6500-Digital-Thermometer-Reliability-Accuracy/dp/B01EMD9V96

You can just bend the probe wire and put about 4 inches into the tube and lay the chat collector on it (no need to drill holes for thermocouple placement, etc). This gives you continuous temp readings for only about $20.

Here's my rough method, which changes somewhat depending on the beans and the external temperature.

1. warm unit to 300F
2. drop about 150g of beans in. Temp=low, fan=high
3. when beans reach about 340F switch to temp=medium and start to slow the fan. You should get to 340 about 3 minutes after your bean drop.
4. when beans reach about 390F, switch to high and lower fan even more (keep beans circulating slowly so no scorching on the bottom). You should reach first crack between about 410 and 430F.
5. Use your growing experience to choose a color, smell and temp after first crack as your stopping point. There's a color swatch article on the Sweet Marias site. To stop, switch to cool cycle and turn the fan all the way up. It will stop itself after a couple minutes when it gets down to about 180F.

This is the one I'm using. There are several other options available as well. I know there's one with the vent holes in the black portion cut to resemble coffee beans and leaves as well.

Different varietals will give different crack sounds, but generally, you'll hear first crack sounding kind of comparable to popcorn popping. Second crack is where you're going to see more variance in how much time from first crack, and in volume. Usually 2nd crack is comparable to the sound of Rice Krispies when the milk hits them.

If your popper is getting pretty hot you can have second crack almost on top of first crack. Ambient air temperature definitely comes into play doing popper roasting as well.

About the lowest air temp I could roast at was 50 degrees (F). This time of year, if temps are in the 80s, it will definitely speed up the roast a little, but when you're doing popper roasting, those things come into play.

Keep up the roasting, it's a fun, rewarding hobby!

I've tried different ways of getting more control and extending out the middle part of the roast between 1st and 2nd crack, including using a small hair dryer to blow more air into the chamber.

I also have this about 80% built waiting for me to get back to it.

This is something I want to build too.

On their Website they seem to have raw coffee of two origins:

• El Salvadorian: http://www.costco.com/Rainforest-Alliance-Green-Unroasted-Arabica-Coffee-3.75-lb.-Can-6-pack.product.100054969.html

and

• Honduran: https://www.costco.com/Organic-Green-Unroasted-Arabica-Coffee-3.75-lb-Can-6-pack.product.100109697.html

Here is a picture of my setup.

I bypassed the electronics of the bread machine so that as soon as I plug it in the motor just stirs constantly instead of going through it's kneading and pulsing cycles. This link was very helpful in that process.

I have a thermometer in the side of the roaster and I am able to keep the temp of the bean mass.

EDIT: forgot a preposition

I just picked up an aeropress recently. 100% lived up to the hype! That attachment looks awesome, add to cart!

Here is the roaster link, i went with the upgraded 110-120v model. https://www.amazon.com/gp/product/B07Q3KZ5G6

It looks like Amazon does sell the black one. But with their warehouse fulfillment system, it's a shot in the dark as to which model you'll actually receive.

[edit] Btw, I'm not saying that I initially ordered the black one and received a red one instead. I definitely purchased the red one on purpose, I just didn't know that it was made differently.

I drilled a hole and inserted a candy thermometer, this one in fact. It has to be a candy thermometer not one for boiling water because the air temp will get up over 400F.

As others have mentioned, it's not strictly necessary, but it does help you know when the pot is pre-heated and it's also useful for slowing temperature rise to lengthen the roast.

When it's getting close, you'll hear the "first crack" and feel increased resistance when spinning the Whirley Pop handle as the beans continue roasting.

I can't find the Cat and Cloud episode now, but Charles Jack (their money guy) has presented this info on their podcast and a couple of other places - including SCA - which you can find that presentation here.

Please let me know if this isn't allowed - checked the rules and it didn't say anything about selling.

I have 2 Genecafe CBR-101 small coffee roasters for sale. They both require the heating element to be replaced. They power up, the fan blows fine, and they turn absolutely fine but don't get hot. We've replaced it on one of them years ago and it cost about £75. They were both used a lot, but are in good condition excepting the heating element.

Cost about £400 new.

They're really good little roasters. You get about 200-250g per batch. Super easy to roast with. Have them listed on Gumtree for £125 each. Feel free to make an offer and I'll consider it. Can include delivery in the UK. Outside the UK shipping will be extra depending on where you are.

The other one is the exact same model but black. More photos on the Gumtree listing

I thought the same thing. I've been getting them for about two years now. The quality seems great, but, this is the only green bean I've had experience with. It's consistent, I'll give it that much. We've gone through almost 100 pounds of the stuff!

Here's the link. We've had both the organic and non. Both have been great.

Edit: link

I don't think that datalogger is supported by Artisan.

For a cheap datalogger, get the Mastech MS6514. Under $50, shipped, though from China so it can take a while.

If you're down with roasting on a $20 popcorn popper from Target, I did two write-ups on Hubksi regarding my results, both roasting with it and then modifying it to get it to go darker:

http://hubski.com/pub?id=72859

http://hubski.com/pub?id=75062

From what I've read, stovetop is harder to get an even roast for beginners, but I don't have actual first hand experience to back that up.

Whatever you do, have fun and enjoy!

Yes, you can see the roast I did yesterday somewhere in this sub before I removed the thermostat. I took the thermostat off today using these instructions. At first when I reassembled it was blowing cold air (and I was about to get upset about throwing money down the drain). But, after a little research, I realized that I just damaged the thermostat when prying it loose- so I needed to take it off completely , then solder the wires together (bypassing the thermostat all together). Worked great! Although I did see some cratering on the beans. I think I will try to remedy this next time by roasting a slightly bigger batch.

I know you didn’t ask for a link but these are the ones I bought: Yueyang Stainless Steel Grilled Cage,BBQ Grill Roaster,BBQ Rolling Grill Basket for Vegetables,Rotisserie Grill Peanut Beans French Fries Basket,Grilling Accessories https://www.amazon.com/dp/B08C2SZMP3/ref=cm_sw_r_cp_api_glt_fabc_SX87D0WAXYRPBBM9KDC9?_encoding=UTF8&psc=1

I was going to go with RK Drums but not at that price. These wer Uber cheap and work very well. All I had to do was square off and enlarge the holes to fit a 1/2” spit or however big it is.

I use these for cold brew in mason jars and I think they work well. Of course this particular one is sold out.

french press filter bags

I got a Harbor Freight one in a similar price range. I kind of regret it though as I want to take more control of my roasts and have the ability to play with more variables.

If you're of the same mind, you might want to give the Wagner 750 a look instead:

https://www.amazon.com/dp/B076T8N525/ref=cm_sw_r_cp_apa_glt_fabc_RVJCVZMADTD125BX4AXQ

Then again, you may not want to drop that much money into a hobby right off the bat.

From what I gather, the 8 cup is the most common.

I got this one:

What heat gun are you planning to use?

This is the Great Northern stovetop popper in stainless steel. I modded it slightly by replacing a tension knob with a grilling thermometer from a Weber grill (had to drill out the hole a little).

Here’s an unaffiliated link to the popper:

Great Northern Popcorn Original Stainless Steel Stove Top 6-1/2-Quart Popcorn Popper https://www.amazon.com/dp/B00608D66G/ref=cm_sw_r_cp_api_glt_fabc_NE8S9E7F1PEFXFWGG9PE

I keep the lid closed while roasting under the oven hood. First crack around 350* and I pulled it off around 390*. Immediately transferred to a colander to separate the chaff over a large baking sheet (still under the oven hood). Shaken gently until beans are cool enough to touch and then laid out to cool completely.

Works well for me,so far the last few months.

Amazon link in one direction it doesnt touch, but spinning in the other direction it does. I noticed it was getting stuck in the rim of the basket, so i use pliers to smooth the rim out. I had also drilled the holes larger on the side where the spindle goes through. The idea was to let it wiggle free if it ever gets stuck.

Culina Stainless Steel Square BBQ, Vegetable and Grilling Basket https://www.amazon.com/dp/B00YBF97Z4/ref=cm_sw_r_cp_api_glc_fabc_cidbGbZM1VZ6Z

This is what I used for a long time. It was perfect when I was roasting about a pound or so at a time. I would put a little fan underneath and just shuffle it around. Chaff would fly up easily and the beans would cool quickly.

Lol, no no that must be in taiwanese currency. It’s about 800 or so for the roaster and cooler.

Target has whirly blades for less than $14. And I found this thing on amazon for about half that amount.

I know of people who have used this model, available from Amazon UK. I think it is made in Germany, so may well be available from other European Amazon sites too.

I ended up using this one from Mill City for the BT and this one here from Amazon for the ET which needs to be smaller since it can hit the basket

As for buying the thermocouple probe, I found one on Amazon for $25. With this one, you'll have to manually log temperature. If you want to connect it to a computer and use Artisan (open-source roasting software), you can pick up a Mastech 6511 for around $50 (I'm planning to do this eventually). I also got a more substantial probe for around $10. It's much easier to position and doesn't move around as much. I use this one to measure bean temp.

Installation was pretty easy. If your bread machine is similar to mine, the bottom corners of the bread pan should be angled at a 45° angle (if not, it's not a big deal - you can just insert the probe through the side wall, it's just more convenient to have it at an angle pointing up bc it stays in place). I drilled through the side of the pan with a drill bit just slightly larger than the diameter of the probe (drill from the inside so that the metal shards from drilling end up on the outside rather than the inside, and make sure to clean it after you're done), you just insert the probe so that it'll be situated within the bean mass. Try to keep the entire probe 'submerged' and make sure the spinning arm of the bread machine doesn't hit it. I use the other thermocouple that came with the thermocouple display to measure environmental temp within the bread machine. I did this by wrapping it around the small metal handle of the bread pan and positioning it a few inches above the beans (make sure it's not in the path of the HG, or else you'll get inaccurate readings).

I bought the aluminum one because its cheaper. But if I were to do it over, I would buy the stainless steel one. From what I've researched, the stainless steel one delivers much more even results because it has better heat distribution.

Another important factor is to have a Cast iron skillet or similar under the pot. This helps for more even heating also. Or you could do what I did and buy a cast iron electric hot plate for your heat source. Here is the link: https://www.amazon.com/gp/product/B081DMHYBD/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

This is the only one I will use as I have tried other 'brands', but none came close to it. The build quality, tolerances, etc. are nicely done.

https://www.amazon.com/Thunder-Group-Cup-Flour-Sifter/dp/B001PZ9GU4

I use fans like this to cool. GDSTIME Big Airflow Dual 120mm Fans DC 12V Powered Fan with AC 110V - 240V Speed Control, Cabinet Chassis Cooling Fan, Server Workstation Cooling Fan https://www.amazon.com/dp/B07WSZWNMM/ref=cm_sw_r_cp_tai_h4ctFbHJRTPX5

I have found it hard to get incremental hole sizes... usually holes are 1/16" 1/4" 1/2". Found this 1/4" online which could be cut into 6 1x1' layers.

M-D Building Products 84327 .020-Inch Thick 3-Feet by 3-Feet Small Hole Aluminum Sheet, Black https://www.amazon.ca/dp/B007NG6EQI/ref=cm_sw_r_cp_api_i_v.jhFbHB3M46B

Drilling on aluminum that thin is risky though. My aluminum is .025" thick because supermarkets usually have better quality.

Assuming you have quick access to the outdoors in a place that you can get a little messy.

1. Get a tiny portable fan and a collander.
2. Plugin the fan outside pointing upwards and put the collander on top.
3. When you're ready to end the roast, quickly take the roaster outside, dump into the collander and turn on the fan.
4. Shake collander containing the beans continuously above the fan while it cools.

This will both help the roast cool more quickly and blow off all the chaff that you don't want. Don't worry too much about the chaff lying around, it will blow away naturally within 24 hours, or do and sweep it up. This process worked well for me before upgrading to a Behmor.

I not familiar with that roaster, when I search at Amazon, I found a model SCR-301, but had a different brand name.

This one

Is it that type, heats the beans from below and has arms to stir the beans?

I would think those are probably more sensitive to batch size to get good agitation and insure the beans roast evenly. You didn't say how large the batch was you attempted, but you could try smaller and see if that helps with the uniformity.

Also, what type of beans and purchased where?

BTW, I live in Orlando and roast outside all the time, never notice humidity affecting the batch, but I use a Behmor.

This is what I got from Amazon and yes, I use canning funnel from canadian tire. The sifter sits almost perfectly in this funnel. All sifters seem to come from China, no exceptions, at least on amazon CA. Mine unit had the wired agitator touch the mesh so I bent them in S-shape and slightly compressed them towards the axle.

It's THIS motor. Or at least, that's what shows up on my Amazon order page. I bought it years ago though, so I can't promise they haven't changed it any.

I was considering the Mill City beans but actually instead went for these: https://www.amazon.com/gp/product/B0796FYSNX/ They were the cheapest greens I could find on Amazon with Prime shipping.

Mill City would have been close to $40 for their 10lbs of beans (including shipping). These, while only 3lbs (which is enough to season the roaster) were $18 with free shipping.

Got it from Amazon. Shipping can take awhile since it's direct from Korea. I did expedited shipping, still took a couple weeks. https://www.amazon.com/dp/B01MZYZT5B/ref=cm_sw_r_cp_apa_cUcLBbQJMFKPB

https://www.amazon.com/Sofias-Findings-Liters-American-Tequila-Whiskey/dp/B00VO3DNL0?th=1 something like this may work, just put your own syrup in. or put whiskey in first, age, bottle or drink, then syrup in for a while, bottle up or chug it like super troopers, then green coffee. although honestly i would probably do a whiskey rinse, do you really want sticky syrup on the beans going in the roaster? I think I smell a fire.

but if you did a whiskey rinse on the barrel for a few days, it would be delicious whiskey( i imagine) and you may still get some mapley flavors coming through after aging the greens. Fuck I might try this now. to do all the steps properly even with a small barrel feels like atleast a years worth of bullshit just to test it out, but a fun project all the way

This? https://www.amazon.com/Coffee-Roasting-Machine-Heating-Roaster/dp/B08JQL3LGV

Never used it- but I read once that the flavor profile from something like this and something that roasts using metal (like a hot top). So just be aware. If you are going this route you might just consider making your own- there's a bunch of how-tos out there on it. Instead of glass they use a steel cage....

Oops! Edited. I meant flour sifter*.

This is the one I bought.

I'm actually planning to rebuild it soon, because it's a little janky.

What I like about the flour sifter, is that you can get really even roasts, and because you're heating from below, the air blows the chaff out of the top, which is really nice. You basically just mount the heat gun underneath, then you use a drill to turn the flour sifter handle.

On my next iteration, I think I'm going to use a motor and some gears to power it instead of the drill.

I don't know about that popcorn popper. The West Bend Poppery II is the favored model as it moves the hot air into the roast chamber in a circular motion from the bottom, which gives the necessary movement of the beans to prevent scorching and under-roasting. If you have $30-50 to spend you should be able to get one off ebay.

I don't know...dirt cheap heat guns can be pretty reliable if you get the right ones.

Is it the $280 VT-750C? Unless that thing is guaranteed to last >10 years, that's a pretty steep price for a HG. Its warranty is a pitiful 1 year for something so expensive. My Porter Cable also gives extremely consistent roasts, and it was gotten for $28 as used, good condition. After 20 lbs roasted, it's still functioning like new. Nothing melted. Time will tell how good a value it is for $40 (new). I only wish the dial were stepped instead of continuous, because the wattage variable function is also stepped. That's pretty much my only gripe about it.

Regarding the level of stress on a variable HG, as long as it's staying well under the HG's rated maximum wattage, it will survive a long time, regardless of other variables, as long as it's well designed. It's not the high intake air temperature that should stress the heating element; it's the temperature delta between the intake and output air that should be concerning. Higher delta means the heating element has to be hotter in order to accommodate the delta.

For example, let's take the cases of the HG pulling hot air, and not: (1.) the intake temperature a very hot 150°F, and the output is 450°. That's actually better for the HG than if (2.) the intake were much cooler (say, 60°), and the output also 450°, because the heating element would necessarily be much hotter in the latter scenario, and would pull more wattage.

That link didn't resolve. I removed the reference and it's good to go! I'm currently using a sifter/heat gun because I prefer the taste of air roasting but saving this for later. Great looking roasts.

Its just a small $16 Mochiglory Rotisserie Basket Coffee Bean BBQ Grill Roaster Drum from AMZ. With two 8 in by 1/4 bolts on either end as axels framed on a 2*4 and 2*6 frame. I mount it on a camp stove in my back yard. Then spin the barrel with a drill. I use a c - clamp to hold the trigger of the drill as a precise speed. Then cover the frame with a baking pan. The Roasting basket was the only item I did not already own - have in my garage. So the total cost for the rig is less than $20 so far.

​

I got it on Amazon, there are a few different brands selling the same thing. I found the cheapest price at the time and got one that has a two tray system, that catches chaff and small / broken beans. Highly recommend for the SR800. Less wear and tear on the roaster (I assume), quicker start on the next roast, and much faster cooling.

https://www.amazon.com/dp/B08B4KHZTM/ref=sbl\_dpx\_kitchen-coffee-appliances\_B08B4KHZTM\_0

Yeah, too fast. You want first crack to be between around 9-12 minutes, usually. Sometimes it can be longer.

You can buy this to wire in-line with the power and it will let you regulate the temperature and air speed a bit. I did this:
https://www.amazon.com/gp/product/B00LODGP2E/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Be aware it will slow the airflow down as well and you won't be able to move the beans as easily. Maybe there is a way to put it just in line with the heater and not the fan as well... I use the Hottop now.

Will do the same job but cheaper

I use this for everything food related. Bought over 5 years ago. 0.1g accuracy, 3kg max though. High accuracy and high capacity tend not to be found together for some reason. Also cheap and high accuracy tend not to be found together either.

I get bean temp with drilling a hole and it works very well for me. I also have an SR800 with extention tube.

I love using this setup because it is accurate and simple. Plave the Thermometer about 2/3s of the way down the chamber and the chaft collector lid will still sit down on the top of the extention tube.

ThermoPro Wireless Meat... https://www.amazon.com/dp/B08K2G5Y78?ref=ppx_pop_mob_ap_share

I use this with my sr800. It has a bluetooth phone app but I have never used it.

I made a Google sheets doc that I track temps an do some charting

hehe i have a slightly different roasting log table

this is more about keeping track of purchased green beans, the roast weight ratios (i started timing each batch but then got lazy) to find out how much my beans is actually costing in the end.

Exactly this

Was roasting with a pop corn popper in an appartement for years (until I moved into a house and bought a Kaldi Wilde).

My setup included a pretty powerful duct-fan (6 inches diameter, 250CFM). The most important moment is actually once you pour the beans out of the roster between end of roast and cooling. That’s when most of the smoke goes out and you need to make sure you have the duct hose very close. The fan is also very useful to help with rapid cooling of your beans. I still use an improved similar setup with the Kaldi Wilde for cooling.

iPower 6 Inch 240 CFM Inline Duct... https://www.amazon.com/dp/B08M41B2SP?ref=ppx_pop_mob_ap_share

Smell won't be so bad on day 1 but it's definitely a thing. I use to just stink up the house when I shared one with a few people. One guy made curry, I made coffee.. moved to super tight apartment building and stopped roasting. Now in more of a condo situation I choose to roast again & hope the neighbors are cool with it. Roommate HATES it but likes the fresh coffee more and approves

For chaff, this was a game changer for me: https://www.amazon.com/dp/B089WBHMG5?ref=ppx_pop_mob_ap_share

Pair it with a budget digital BBQ Thermometer like this one https://www.amazon.com/Wireless-Digital-Thermometer-Grilling-Smoking/dp/B08BXCGD76/ and you will be unstoppable! I just tucked one of the probes under the lid of the popper. I love this roaster set up, make sure you have a colander and a strong box fan ready to rapid cool the beans after roasting as well. I roasted like this for years, I just recently went down the rabbit hole with a SR800 with a Razzo V5 chamber and a Mastech MS6514 USB Thermometer so I can log the temps on my laptop with Artisan software. I can tell you that my $500+ SR800 setup produces only marginally better roasts and has the same batch capacity as my $90 crank popper set up. Hopefully that helps you from going to deep down roasting rabbit hole!

A simple and cheap upgrade would be a voltage regulator like this one.

I have it on my hot air popper and though it's hard to be consistent, it really does allow me a lot of control.

But I'm also curious about the Stir Crazy Turbo Oven! I've been on this forum for a year and a half and this is the first time I've heard of it.

I’m in Qatar so it’s a local offering that’s why I’m interested

If you research a company called Port of Mocha in California you can see the owner he had some crazy trips to Yemen. In one trip he was capture by the Houthi rebels and had to have the state department arrange his release

https://www.amazon.com/Monk-Mokha-Dave-Eggers/dp/1101947314

Buy something like this - https://www.amazon.com/BBQ-Grill-Mesh-Mat-15-75x13inches/dp/B073XD9W9D

It’s mesh for grilling outside and up to 500 f. I measured the width of the canister and cut long ways then starting cutting to make it fit. It actually should fit in very snug because there’s a plastic “border” inside.

Oh. Hmm. That complicates things. An air popper roaster definitely works fine. The one I linked is nice because it has a timer, a heat dial and a high/low fan speed plus a lid that catches chaff etc. Perhaps the Fresh Roast 540? https://www.amazon.com/Fresh-Roast-SR540/dp/B07RT6S5YH.

Basically, I think you can get into roasting for $1-300 US but that's based on what is available here (US).

Hello! I recently set up my new Kaldi Fortis and ran into some issues measuring the output of propane to my burner. As the picture shows, there is a valve and gauge installed in the line. While the valve works at controlling the size of the flame on the burner (will be upgrading to a needle valve soon for greater control), the gauge constantly reads zero. Here is the gauge being used in the setup. Any thoughts as to why it's not measuring pressure?

i keep track of my initial and final weights during roasting (and other random info) here, if you're interested :)

in the beginning i was timing the 1st 2nd cracks and the stop time... eventually i got lazy.

They make couplers that have different sizes on each end. For example, the one i have is 6 mm on one end and 5 mm on the other.

They tighten with set screws, so it doesn’t have to be a perfect fit. You can file down to flatten the end of the flour sifter shaft so that the set screws sits better on it without slipping. Then, as i said, use hose clamps as extra precaution so the set screws don’t wiggle back out (or use something like locktite glue to keep them in).

The ones you linked to are all the rage now since they sit flat and tidy on shelves. You are probably looking for simple zipper pouches with a valve and lining like these: https://www.amazon.com/Kraft-Coffee-Bags-Valve-Pack/dp/B08GP4GJX5

Buying in small quantities really jacks up the price per bag (looks like ±60¢ is the going rate). Check out PBFY: https://pbfy.com to see all the options that are available and then query those on Amazon to see if anyone is selling smaller lots -- but remember that you're going to be paying over 60¢ per bag for a small lot versus 25¢ per bag per thousand.

I'll be honest, I had a similar setup for a long time then I bought one of those bean coolers on amazon. Never though it was worth the price until I tried them. Cooled the beans quicker and it's almost silent. If you ever get tired of this setup or need to replace it, I'd seriously consider one of these:

https://www.amazon.ca/JIAWANSHUN-Electric-Roasting-Cooling-Scattered/dp/B08B4KHZTM/

They hold about 1lbs green beans (pre-roast weight). If that is not sufficient, I believe they have a bigger model.

If you want to recreate something similar as a DIY, just look for a 140mm (200mm if your setup can take it) computer case fan and a power supply to power it. Then it's just a question how you want to setup the fan to cool the beans.

This is the one I bought. Cheers!

I use the TIMEMORE scale off of Amazon and I love it. USB-C so I can just recharge it and start using again. I would highly recommend. https://www.amazon.com/TIMEMORE-Coffee-Scale-Basic-Timer/dp/B07YCS74GJ

I've been searching for a way to adjust the temperature on my popcorn roaster.

Light dial, variac, fan speed controller, some transformers. This caught my eyes. Seems pretty good that these can measure and adjust temperature! But I was wondering, if anyone else had luck with these in their setup?

Unfortunately the converter you'd need isn't an inexpensive product. Note that the converter I linked to is rated at 1500watts - which is still too small. It's generally not recommended to use a converter.

I used Avery’s online program to design the label. They had some coffee templates I used and the coffee cup in the center of our logo was their clip art. So pretty easy!

I do have a color laser at home so that helped.

So ir and meat thermometers are not very consistent?

I paid 60 for it on Amazon. I'm not sure why the price has jumped, but you might be able to find it less expensive elsewhere.

Other considerations: I drink/roast a pound of coffee a week. That's 52 pounds a year. Best deal I've found so far is Costco's Organic Green Coffee beans only sold on their online shop for < $5/pound ($109/23 pounds). With those beans, I can drink organic coffee for an entire year for less than $300. Also, I roast 18-20oz at a time with the popcorn poppers. No complaints there & it takes me less than 30 minutes for the entire process start2finish. Considering most daily coffee drinkers spend almost as much money on annual fuel expenditures as they do their coffee, I'd like to say I'm on to something here.

As long as you're already browsing Alibaba, adding a transformer to the order isn't that expensive...

Here is a more "analog" method to modify your popper with a few dollars worth of hardware.

Here are instructions for doing the same type of mod, but putting an arduino controller in the loop instead of the light-switch type controls.

Hope one of those links is close to what you're looking for.

I'm happy roasting 8 oz batches with a Gene Cafe. I've repaired it twice over 10 years of constant use. I cool on my downdraft stove with a "grill basket" which is pretty effective:

https://www.amazon.com/TableCraft-Stainless-16-Inch-Grilling-Basket/dp/B00CQQF38K

I bought this one a while back. It works very well at cooling the beans quickly and does a good job of pulling off the chaff too. It was probably about $20 less when I purchased it and it was a steal at that price. I'd say shop around. If you don't currently have a way of separating chaff, I'd say definitely go with a two tray design for that purpose. It saves a lot of work and mess.

Time to FC depends on how much beans you're roasting and also your percentages for the phases of roasting (https://www.bloom.coffee/en/blog/the-5-stages-of-roasting) and wouldn't necessarily compare your times to anyone else's. So I would calculate that first. Virtual Coffee Lab on YouTube has great videos about the phases of roasting.

But if it turns out you're rushing through the roast I agree with using a power modulator to decrease heat levels, something like https://www.amazon.com/dp/B005Z63ZN8 but make sure the wattage of your popper matches the modulator wattage.

Thank you! Don't have a Harbor Freight near us, but I did find this on Amazon for $18: https://www.amazon.com/gp/product/B08XYT46VD/

To my eye, it looks to be more or less identical, just rebranded.

This is basically what I did, although i already had the pi and it is running a newer rapsbian than stretch.

https://artisan-roasterscope.blogspot.com/2019/02/running-artisan-on-raspberry-pi.html

I have the phidget 1051_2b that connects the thermometer to usb.

I have this screen:

I ended up having a friend 3D print a case for the lcd display, although i believe that company does sell a case. When not roasting, i use the display to display info from a home weather station/ home automaton status.

There is also an Artisan for windows. The phidget sensor works with windows too. I used a laptop for awhile… but the small footprint of the pi is more convenient and my laptop sucks.

Back when i used a drill i had a hose clamp that had a thumb screw so i could slide that up and quickly hand tighten to keep the trigger depressed.

I think the cheapest way out would be to buy foil lined block bottom craft bags like these: https://www.amazon.com/dp/B07WWVVV81 and then get a hipster marketing company to design a stamp for you. When done right, the results can be striking.

No the kit came as an all in one from Fresh Roast on Amazon.

I watched a few YouTube videos and read some guides, and have been listening to podcasts for the past few weeks about coffee roasting. Starting the machine was nerve-wracking as nobody likes to flub their first anything heh, but it turned out okay so far!

Thanks for the kind comments :)

I've ordered from Sweet Maria's a few times in the last few years, but after I placed an order in July 2018 my credit card was compromised. Can't say with certainty that it was Sweet Maria's, but I pretty much only used that card on Amazon outside of that order.

Since then, I've been using Privacy.com to make single use digital credit cards for when I order from them and that's been working for me.

My stove has a downdraft that I pipe the roster exhaust into but I also dump the beans into one of these I got from a dollar store and put it over the downdraft. I'd image any sort of air movement across/through would work with the beans in a basket like this and raised up off whatever surface is below them:

Online and probably pushing to local restaurants/cafes. We've really only talked about who the producers are we are working with via a nice full bio on each of them on the site and a blurb on social media. Will probably start posting details about what we've done so far and how each bag helps in the near future. We've thought about something like upwork.com to find a marketing resource, but havent pulled the trigger yet.

You are looking for a CRM application. If you do a search you can find a bunch that will offer different services for different prices.

I just picked one off the list: https://www.odoo.com/page/crm I don't know anything about this particular one but you can get a feel for these systems by looking at what this one particular one has to offer.

The systems will include modules that offer websites with ecommerce and shipping and ordering, invoicing, POS, and a wide range of other features.

Shop around, attend some webinars and ask for some demos.

I found these instructions really helpful. And I cant imagine poppers differ that much on the inside.

At first when I reassembled mine it was blowing cold air (and I was about to get upset about throwing money down the drain). But, after a little research, I realized that I just damaged the thermostat when prying it loose- so I just needed to bypass it completely. just my two cents

I think the blue one nope, but for red and black one you can buy it on Amazon.

https://www.amazon.com/Sandbox-Coffee-Roaster-Machine-Cooling/dp/B08Q3QT9HV?ref_=ast_sto_dp&amp;th=1

but you know, the price cannot compare to the fund version :)

Rob Hoos' Modulating the Flavor of Coffee is one I'd recommend. Willem Boot has some free stuff that has been invaluable, though modern wisdom goes against some of his advice. Tim Wendelboe has a few videos out there that I've found worth revisiting.

I'd actually advise to stay away from Rao stuff at least at first. He has some good info, but he also teaches some hocus-pocus stuff as "Commandments." If he said something to the effect of "when you're starting out, here's some general rules you should try to follow" I'd be all for it, but instead he teaches them as Absolute Truths and they simply are wrong in that context. It may be that the spirit of his advice is right for newbies, but the way he delivers it is definitely all wrong. He's the reason so many people think they can look at a profile and have some idea what a coffee tastes like (they can't, profiles are useful relative to other profiles on the same equipment, period).

If you're really into the chemistry and science of coffee, Illy's book is probably the most comprehensive piece of modern literature on the subject. It's pretty freaking dense though.

OH, this is not yours. you are just trying to make something like this and you dont know how to connect the glass to a metal funnel below it. i think i saw another person make one like this and he just had the glass sitting on the metal funnel. then to connect them he used aluminum tape i think, which was meant to withstand the high temps.

is this safe to use around food? no idea.

I had a similar experience with the same setup. I now use an 8&quot; inline fan with a small extension that a colander sits in. As soon as the cycle is done, I hit cool then immediately dump into the colander with the fan on high and stir the beans constantly. The beans are usually cool to room temperature in about a minute and a half
