Tonight I start the filtering process of my newest sake.

So after failing to make Koji for this month's batch of Sake, twice, I decided to buy the amount I needed. I learned a few lessons along the way. Koji spores need to be sifted corrected and you CAN NOT use a coffee grinder to grind up the Koji spored rice to make the same stuff you purchase. In the future I will be building a spore sifter of sorts surrounded by plastic to keep the spores from going everywhere. FYI it is about a $10.00 difference in my batch whether I make the koji and/or the koji spores myself.
