I've got a yeast starter going on a stir plate, which I've done many times in the past, but this time, it looks like chunks whirling around in the flask. I've never seen that happen before, usually it's a consistent caramel color whirling around. Since my last batch went south due to yeast problems, it's time to ask for help.
I started the yeast about 7pm Monday evening, planning to brew this morning. I added 2 smack packs, one of them with a July date, one with a January date. 1300 ML of water to make a starter for 10 gallons.
This morning, I turned the stir plate off, waited for everything to settle, and it looks like solid yeast in the bottom of the flask. Turned the plate back on, and sure enough, the solid pack of what looks like yeast creates chunks that float and whirl around.
Is this problematic, or the best yeast starter I've ever made?
