After 25 years of brewing and making yeast starters the way it was done 20+ years ago, I got a stir plate and I am AMAZED at what it does to get a starter going. I've built up to 1500mL of pitching small amounts of 1.040 OG wort into the starter. Can I take it off the stir plate, let it settle and then decant off most of the fermented liquid, throw it into the fridge? Then 24hrs before I brew, add more wort at 1.040 and put it on the stir plate to kickstart and dilute the "slurry"?
BTW, this is an ale yeast.
