Please note that using the fresh Hazelnuts in this Makgeolli was an experiment which had poor results in the end product due to the late amount of oil in the nuts. I have made several successful Hazelnut brews in the past using Hazelnut Meal and I recommend that you use the meal for the best outcome. Don’t know what Hazelnut Meal is? Here is a link with a picture of it. https://www.amazon.com/Bobs-Red-Mill-Hazelnut-ounces/dp/B003UFDJRS
A note to anyone possibly thinking about making this Makgeolli. Using fresh Hazelnuts was an experiment that I will not repeat due to the large amount of oil in the fresh nuts. My regular process is to use Hazelnut Meal and I include a link so that if you have never heard of this product or seen it you will know what to look for. https://www.amazon.com/Bobs-Red-Mill-Hazelnut-ounces/dp/B003UFDJRS
Note for anyone who may be thinking about making this flavor of Makgeolli. The fresh roasted Hazelnuts I used this time did not work well as the nuts contain too much oil. My Hazelnut brews always turn out well when I use Hazelnut Meal and not fresh nuts. Here is a link to show you what I mean by Hazelnut Meal. https://www.amazon.com/Bobs-Red-Mill-Hazelnut-ounces/dp/B003UFDJRS
