That's a good question. I guess it would depend on how hot your house gets. If you have huge temp swings, and the house is regularly getting into the mid 80's and 90's temperature wise, then it might be a good idea. I have always just kept the jars in my basement where it is always around 60 or 70. As long as your temps aren't crazy and you can keep it out of sunlight, your baccy should be ok. If you have really high temps in your house and don't have a cool, dark place to store it, a wine cooler might be a good idea.
