While the koji making is rolling on, I can do a lot of other stuff like read, ski, do carpentry and also make miso. This season I plan on making about 7 batches – 2 barley, 2 rice, 1 herb, 1 chickpea and experiment in making rye koji and rye miso. 
Now that I have quite a bit of barley koji with more to come, I will make some barley miso.
