i pitched danish lager yeast at 56 on Jan 12th, set up primary fermentation on my back porch. it sat for almost a week at 50ish temps, then we got an arctic freeze in vermont - porch temperature was in the 20's. thermometer on ale pail only goes down to 36, and it was definitely colder than that . i couldn't move it off the porch for 2 days, and now it's stable at 54. can the yeast recover? it had a good week at lagering temps before it dropped. i had planned to move to secondary this weekend, but don't want to shock the yeast too much. any advice?
