I did a split brew on the weekend. made a pilsner wort (OG around 1.055) and divided it in half. 3 gallons were fermented with WLP530 and some orange peel, and 3 gallons fermented with WLP510. I have the 510 in my basement, where its probably 68-70 F. it started fermenting in 24 hr. last night, i checked on it - day 3 - and fermentation looks like it stopped. this morning, i gave it a gentle swirl to see if i could get any airlock activity. but i'm wondering what one would expect with 510. i don't expect fermentation (and krausen) to peter out in 3 days. and the 530 started fermenting after 40 hours and is still fermenting nicely (at 72 F) thoughts?
