San fran lager strain
« on: June 30, 2012, 09:26:59 AM »
I have my baltic porter with san fran lager yeast that has been at about 58-60F for 15 days now.  I checked the gravity last night and it has dropped from 1.085 to 1.030.  Fermentation has slowed a bit but still showing active signs.  My question is regarding when I can begin to drop the temp a bit with this strain as this is the first time I have used it.  The carboy is sitting in my keezer with the rest of my beer and I am hoping to be able to start to chill it down a bit.  Can I expect fermentation to continue safely if I drop down towards 48-50F (likely a few degrees a day)?  My goal is a gravity around 1.018-1.020.

If you start dropping the temp you most likely will not get much more attenuation. If you need it to drop a few more points, I would raise the temp a few degrees and give the carboy a gentle swirl and give it another week or so.

+1.  You are at about 64% attenuation now.  It's only got a few more points in it....
