Coming in years later here!
I just had to dump my first attempt at sake using Will Auld's guide. Very disappointing haha.
It was super harsh. Like nail polish. Unfortunately, I'm not entirely sure what it was that went wrong. Infection? But infection of what?
I had a few known issues:
-My polisher was breaking my rice, so I wasn't starting with the proper polished rice.
-My temperature during the Moto was too high for about 3 days per Will Aulds guide.
Issues I suspect:
-Will's method has yeast pitched right off the bat, but this seems like over-pitching to me since there isn't much sugar available right away. I'll be trying Bob's method of pitching after two days.
-My moromi water additions were 50/50 distilled and spring water. I think I may do JUST distilled next time. I also suspect there was chlorine and or chloramine in the spring water despite it not being on the water profile on the label.
-I'm a little confused on temperatures since the fermentation is so much lower than Wyeast's guidelines. I understand this is to keep lactobacillus down? I'll be using Bob's method this time, but I'll still go the lactic acid addition route and keep the moto temperature lower.
I'm hoping to get good at this and produce some good video guides because it is incredible to me that there isn't a single comprehensive video on sake brewing on youtube.
Any advice to this failed newbie is appreciated.
