So I just got my first Conical and brewed 10 gallons of imperial Porter Saturday. I used a 2-Liter starter from a stir plate of wyeast 1335. I'm considering doing an English Mild on Wednesday(tomorrow) and want to use the same yeast. My Porter was fermenting fairly well already on Sunday Morning, and last night was going pretty much full strength. Would enough yeast have fallen out of suspension by tonight or tomorrow that I can safely take some without affecting the porter in any negative way? I'm considering 2 options, pulling out a small amount tonight(Tuesday) and making a fresh starter and putting on the stir plate over night, or should I just give the yeast another full day in the conical and pull straight from that and add it right to the mild? Or should I just push back my mild for a week until fermentation is closer to being completely finished?
