Cool Storage Location Ideas Please

What about electric coolers such as freezers? 15 1 gallon containers in a freezer would fit quiet nicely.

You could buy a ranco temperature controller from ebay for 50$, wire it up with an extension cord, and set the freezer temp to whatever you'd want and it would hold

If that's too cold, you could do something like this:

You and me both. I live in Central Texas. Nobody has basements here, and it gets quite hot in the summer. I still haven't found a suitable solution for storing a few hundred bottles. For the time being, I bought two used refrigerators and I rigged them with air conditioner thermostats.

I, too, live in a home (Georgia) with a crawlspace and no basement. I regularly store full carboys and always have bottled wine with no problems on the bungs except noticing that slugs like to come in and eat paper tags and labels on bottles. I've since resorted to aluminum tags with marker to ID carboys. Fortunately, I had no problem with slugs trying to eat the ends of my corks where my bottles wines are identified.

Temperature is warmer than I want but since I cannot dedicate a room in the house and the garage regularly goes up to 100F in the summer, it's better than nothing!
