I brewed 2 beers this weekend, BM's Cream of Three Crops and a Scottish Export. I used SA-05 for both and fermentation for each is very different. The water bath they are in is at 66F, maintained by aquarium heater and circulated by aquarium water pump. (Still a winter chill in the basement)
Left: Scottish after 26 hours, O.G = 1.044, frequent large bubbles rising to the surface of beer but no krausen. It appears to be fermenting from the bottom. Airlock activity high.
Cream of Three Crops on the right after 54 hours, O.G. = 1.046, krausen like I usually see.
I hope the Export is ok....... I haven't lost one yet, 1 year brewing and 14 batches so far
