I wrote a short book on the basics of rum distilling, but most of it applies to other liquors. I sell it on amazon, however I'm in the process of putting the same info in the book onto a website for free. Eventually I want to add more info/recipes, but I've been pretty busy with work lately. Feel free to PM me your email if you want a PDF copy of the book.
I think it should be, try this link for it: https://www.amazon.com.au/dp/B071HSK3WX If you email me I'll send you a PDF copy as well
