I'm about to invest in a little freezer to ferment my beer at the correct temperature (I live in Houston, so it's never cold enough in my apartment). Because the mini-freezer will be such a tight fit I am concerned about not being able to use a blow off tube. I measure the carboy and the size for the freezer and there is no way it could fit in there with it. Is there a way to prevent excessive krausen without altering flavor or fermentation? Or, does anyone have any other ideas for me? Thanks!
