Bonus track: How to make Makgeolli the Korean Traditional Rice Wine at Home
Rice wine has been used as a bacteria/sugar source for the fermenting indigo vat in Korea, Japan, and other East Asia regions. I tried to make my own Makgeolli last summer and a photo documentation of each step is here. I noticed that some YouTube channels also introduce the instruction of how to make Makgeolli. I'm sharing a video instruction of how to make Makgeolli by a well-known Korean-American cooking channels Maangchi here.
