I have a question about the temp of the beer when you Pitch. I am using liquid San Fransico style yeast to make a lager. The instructions on the yeast said to pitch between 70-75 deg. When I put the yeast in the carboy it was at 64 degrees. I have the carboy sitting in my garage so the temps stay cool for the lager. I don't think the temp will get over 68 deg. I did make sure and airate the carboy before pitching. Will fermentation start?
