Ditto on the S-33. Furious yeast. I bet you could put four pounds of leather, a bowling pin, and two gallons of maple syrup into a fermenter and this stuff would gnaw right through it. It's like some Andromeda Strain yeast.
I made some brown aleish beer thing the other day, came in at I think 1.065 or something. It looked like a gale warning krausen within a few hours. Three days later, the beer is clear. I'm afraid to stick my hand in there to get a sample lest it come out with just bones and ligaments left. I haven't tasted it yet so who knows if the speed also brings Yum or if its just ho hum.
My cider was 1.056 dropped to 1.008 within 72 hours. I bottled, carbed, and pasteurized. Looks ultra hazy like orange juice so hopefully it will clear in a few months. But still quite tasty even though it's quite juvenile.
