I did my first all-grain brew on Thursday. Fermentation was recommended at 70. I put my carboy in the basement and went out of town for the weekend. When I returned on Sunday I noticed the temp at 62. I have since moved the carboy upstairs where the temp has been raised and is holding around 70, but I have not had any active fermentation since I have been home. Should I be concerned?
I did a yeast starter also. Do I need to add more yeast?
