I have no place in my entire home where the temp stays the same for long periods of time. I use a wood stove to heat most of the winter and central air for the summer. my basement is heated but only when the furnace is being used to heat the living space witch is not often. most times like today my living space is between 65 and 75 f . and the basement will run from 48 to 75 f . for the moment my brew temp has stayed around 70f what to do?
