Hey guys! First post here. I have had much success utilizing several different varieties of yeast balls to ferment rice, barley and sweet potatoes. What I was wondering is if any one you have had success using yeast balls or koji to saccharify and ferment your ordinary potato. The last time I made an attempt, I was trying to make a spin-off tapei, but it didn't seem to turn out right. Has anybody tried to make a potato brew using such a process?
