I have a 3L flask on the way. Should be plentiful.
the Masonite jar is starting to fermen now. This is going to be the big pitch for the RIS. I calculated that I need nearly a week in advance to make 2 steps.
The glass carboy failed the stir test. Too much of a concave on the bottom.
however my 1.5L mason jar passes the step for a 1L starter. I’ll use this for the first step.
in the next few days I will pick up a larger 4-5L flask for the next step.
