I have a question about making miso paste but fermentation is marked as off-topic. Does that include fermented foods?
Miso paste is fermented soy bean paste
Fermented foods are on topic. You are welcome to ask about miso, and also other fermented food such as sauerkraut and pickles.
I guess the confusion may come from the point
Wine-making, Brewing, Distillation and Fermentation
This means that the site doesn't cover the making of alcoholic beverages from scratch, such as making your own beer. The "fermentation" part is to be understood as fermentation in the context of brewing alcohol. Fermentation as part of food production is ok.
If you have questions about the preparation of typical alcoholic drinks, homebrew.stackexchange is the right place. We tend to keep questions from the gray area about fermented drinks with low alcohol content, such as kefir or yeast carbonated soda.
