The krausen on mine just started to go down and I only had 1 day of strong activity. There appears to be a settling down now and the yeast is forming a compact cake at the bottom.
Has anyone experienced only 1 day of strong fermentation activity?
I realize a hydrometer sample is the only way to tell but I want to give it at least a week.
I still have not had occasion to use this yeast, but that sounds interesting. The behavior you're describing (and what some others have posted) is what I usually associate with some British yeasts, WLP002 in particular. Long lag, a quick, highly active ferment, followed by muted hops.
Some of what I am reading makes this sound like a Brit yeast with a low ester profile rather than a US-05 alternative. I have a 10-gal system being built at Morebeer presently. For my inaugural batch, I was going to make a simple, lowly-hopped beer that I keep around for my wife and our friends. I usually use US05 in it because it's clean and reliable. I may split the batch into two 5-gal fermenters and try this yeast side by side with US05.
