Hey guys,
I've put down a kit and kilo (with a bit more dextrose) of a cooper's canadian blonde. The yeast that got recommended to me from my LHBS was the Saflager S-23. I dry pitched the yeast (one pack) at 20 degrees, then brought down to 11 degrees for fermentation. The starting gravity was 1042. Based on the attenuation of the saflager, fermentis states 72-75% attenuation. With some rough calculations:
42 (gravity points) x 0.75 (estimated attenuation percentage) = 31.5
42 - 31.5 = 10.5 = approximately 1.0105 final gravity
It's been in for 17 days and the hydrometer readings between today and 3 days ago has been just 1 point drop in gravity. It seems like it's either slowing down, or is stopping at around 1020. I gave the keg a bit of a swirl around this morning and upped the temp to 12 degrees to hopefully get it going again, just thought I'd also ask a few questions in the meantime before I get home after work:
- Is my estimated final gravity way off?
- Do I need to get another Saflager-s23 to get it going to my estimated final gravity?
-- I can to my LHBS today, but would be preferred to know if I need it first
Hopefully this isn't going to finish at 1020, as that would be an exceedingly light beer ...
