Update on my latest batch.
Several weeks of cold crashing, and the solids have finally settled. I got 2 US quarts of clear yellow, and one of nigori-style. It's very strong, and as predicted, the chemical notes went away. Pleasant nectarine flavors that have never happened before.
I encountered two things. First, what looked like a kahm infestation, but without the unpleasant smell. Now, I ferment a lot of things--kimchi, sauerkraut, kvass, you name it--and kahm happens with all of those. But I've never seen it with rice wine before. I skimmed it off and Bob's your uncle.
Second, it's tangy. Not quite sour, but very very tangy. (Don't get me wrong, I'm still going to drink it). I know this is because about four days in, I added more mash and about two cups of water.
@Miraculix or one of our other potion masters, is there something I'm doing wrong timewise?
