Fermentation Notes, Sweet Stout

Mon 18feb2008: @ 13 hours, no sign of fermentation yet. I'm wondering if this is common for this yeast (I know I should make a starter, but I'm lazy). There was a lag the first time I used this as well. If there are no signs by the time I get home today, I will rehydrate and pitch a packet of Safale S-04 which will probably explode off. I guess I just need to start making starters for everything above 1.040 OG. I have just been considering my yeast cake as a lazy man's starter for my consecutive brews.

UPDATE (Mon 18feb2008): Signs of fermentation have shown sometime between 13 and 21 hours while I was at work. There is a thick white krausen on top of the beer and the airlock was bubbling by 23 hours.

UPDATE (Tues 19feb2008): This morning fermentation is really going. Ambient room temp was 62F, but the fermentor was at 68F. I'm leaving it in the cool part of the condo until fermentation slows down and its not generating so much heat.

UPDATE (Fri 22feb2008): Fermentation has slowed down quite a bit, the gravity right now is at 1.027. I'm expecting it to get down to 1.022-1024, which would be normal considering the pound of unfermentable lactose involved.

UPDATE (Wed 27feb2008): SG reading of 1.024, probably the terminal gravity and is in the range I expected given the unfermentables present.
