Stuck Fermentation, Lager

Postby woodsconsin81 » Thu Jan 21, 2010 10:54 pm

Hey all,

I recently created a wort for a Vienna Lager. I had a Wyeast Munich Lager Yeast slap pack, which I let sit out at room temperature while I was brewing. Once I was done with the boil, I cooled the wort as usual to room temperature, pitched the yeast (which had been sitting at room tempurature for about 3 hours, and then moved my primary to my basement, which was at 46 degrees. I realized that the temperature was a bit too low for a lager, so I moved it into our storage area, off of the cold cement floor, which helped to raise the temperature to 48 degrees, which is within the range of a lager primary fermentation temperature. To date, I have had no activity with the yeast, and have tried to oxygenate several times by stirring the wort. I'm wondering if I might need to re-pitch some yeast. Any thoughts?

Ok, went downstairs tonight and I have some krausening, so it looks like I'm good to go 8) I guess lagers just take a little more patience than ales.

Right on! Lager yeast usually takes a bit longer to get started, and to finish. It's due to having such cold fermentation temperatures, I'm sure. Glad to hear your brew is doing well!

Agreed. Lagers take their good ol' sweet time when getting to work. I also tend to be more motivated and active when ambient temps are in the 65-75 degree range. Glad to hear that your yeast finally got their act together!
Cheers!
