I'm wondering if there are technical barriers to my idea - I really have no space for a proper cellar, and I don't really feel I need to keep my wine at true cellar temperature (55), but I live in TX and even with AC the house gets as high as 82. I don't want my wine that hot, but I'm OK with 70-72.
My pantry is the space underneath my stairs, in the middle of the house with no exterior walls or windows.
Do I need to worry about vapor barrier issues if I'm not trying to keep that space at 55 (ie., is 10 degrees off ambient enough to make the walls sweat in an already air conditioned environment)?
I'm thinking I might just buy a small portable room AC and put it in the pantry and see how that works short term. If I had to insulate the pantry, I could have someone blow in closed-cell foam insulation, but I'm not sure it's necessary....
Thanks for your thoughts.
