Summer temperatures and spririts storage

[Beachfan]

Much has been discussed on the storage of wine. What about spirits. Does vodka get hurt by temperatures in the 80s? What about other spirits? Cognac seems to hold up ok to my liquor cabinet, which is in a room that gets very warm when we're not home.

I assume many liquors wouldn't hold up, such as limone. Kahlua too? Grand Marnier? Any studies out there? Or students?

As far as I know, distilled spirits aren't damaged by heat, or at least not by temperatures that you'd reach outside the oven. Sunlight is a different story. Just as prolonged direct sunlight will fade the color of fabrics, it will also affect the color of brown liquros, lightening them up gradually.

So keep those bottles out of the sun, but I wouldn't worry about the heat. (Vermouth and other lower alcohol aperitifs, on the other hand, should be kept cool.)
