I brewed a porter two and a half weeks ago and I was about to start kegging. I have a original gravity of 1.05 but today when I went to keg it it only got down to 1.025. It was been pretty cold in new york and since it was in a basement it was heated to about 62 degrees.
What do you guys think I should do. Should I let it ferment even more with maybe a light on it to keep it warmer?
