Hi all -
I got such great help and insight after asking my first question on here that I thought I'd give it another go. (PICTURES ATTACHED)
I am harvesting yeast for the first time, and it's from a stout. I racked the beer off, poured in a gallon of boiled and cooled water, let the trub settle, then poured the "milky part" off the trub into this flask. At first, there was a tiny sliver of beer, or at least darker colored liquid from the dark beer, on top as expected. In the last few hours, the dark sliver has grown significantly - from about 1 mm to about 2 inches of a 7ish inch volume height in the flask. Is this just the yeast gradually falling out of suspension (as the yeast falls out, the underlying dark beer/dark liquid color becomes less clouded and therefore dark?)? You can see the yeast cake forming on the bottom as well. (First picture was a few hours in, and now the second picture is 12 hours later)
In the future, I plan to harvest yeast from the starter (which seems way easier and just makes more sense to me), but I thought I'd give this method a try this time.
