Hey guys, hope you can help me out here.
I brewed up a pilsner on Thursday night roughly based on the clone recipe for Victory Prima Pils I found on this site. I used Saflager Saflager S-23 since my LHBS was out of Wyeast 2124.
I just built an active fermentation temperature control system based on the water fermentation chamber builds I found in the DIY section and I set my ferment temp at 50F using. The system works great so far, but I pushed my luck by going away for a couple days this weekend. I loaded up my chilling cooler with ice water before I left in the hopes that it could maintain 50F for 48 hours, but when I got back this afternoon I found that the ice had completely melted and the fermenting beer was up to 62F.
So basically I figure the beer had about two to three days at exactly 50C and about a half a day to a day rising up from 50 to 62. Now that I'm back home should I knock it back down to 50 or just maintain 62? I know that it's generally not a good idea to cool yeast down too much or they might go to sleep and I definitely want this beer to dry out. I was going to do a diacetyl rest anyway, is it a huge deal if it's coming a couple days too early?
Any help that experienced lager brewers can provide would be appreciated.
