I have tried this recipe a couple times now always with the same result: a sour flavored wine that I dont like much.
I have tried a few different rices, all more or less the same. For the first couple small scale attempts I was pretty cavalier about sanitization but after bad results I got strict. Same result.
Has anyone else had trouble?
My thoughts on possible problems:
My jars are tall and skinny?
My yeast balls maybe contaminated?
I should harvest sooner before acid production ramps up I have tried 3wks and 4 wks for harvests)
Any ideas?
Edit-
Additional info: I make the rice the same way I always make rice, well rinsed and soaked, followed by cooking 1:1 or sometimes 1.25:1 water to rice, depending on rice type.
I think one place I haven't been careful enough is pitch temp. I am an impatient person. I'm fairly sure I tried once with cooler temps, but since I can't be sure I made some experiment rice, cooled it off, and layered it with yeast ball. My thoughts were (before my latest try) that Koji is kept very warm to work well and amylase likes warm temps as well. Ofc, I gave the fermenting yeast no respect
High hopes now, plus I don't mind the failures if I still have fun
