Would take a lot to have freezing problems here, if there is a rise in temp I haven't noticed it, can usually take a 5 gallon batch down to 70-75 degrees in 10-20 minutes. the tank held about 73-75 degrees all summer (sits in the shade) I emptied it to move it so not sure what it will hold during our "winter"
