In the time-honored tradition of mothers everywhere, whenever my mom comes over to visit, she starts cleaning and reorganizing. I'd be offended if it weren't so utterly obvious that I really (really) do need help.
The other day, in her furor of tidying, my mother peered into our refrigerator and exclaimed, “Your fridge needs to be cleaned! There's no room for anything in here because it's full of bottles! Do these really all need to be in here?” I assured her they did. “Then you need to get another refrigerator for vermouth,” she retorted.
This is probably true. I have a lot of vermouth in my fridge (what can I say, I like to try all the different brands). But, it’s not just vermouth—there are a variety of different alcohols that do best in the fridge. The rule I use is: If it’s under 15% alcohol or if the base is wine, it goes in the fridge once it’s open.
Spirits like whiskey, rum, gin, vodka, etc. don’t need to be refrigerated because the high alcohol content preserves their integrity. And most liqueurs also have a satisfactorily high alcohol content, as well as sugar that also helps to keep the flavors preserved.
Other Aromatized Wines: A whole world of spiced fortified wines that are less well-known than vermouth exists. They aren’t called "vermouth" because their bitterness does not come from wormwood (instead, they rely on other roots like gentian, or barks like cinchona), but they are similar. And because of the wine base, the same rules apply. This category includes: Punt E Mes, Lillet, Quinquinas, Gentians, and Americanos (like Cocchi Americano).
Fortified Wines: This includes sherry and port, Madeira, and Marsala. Once again, the higher proof keeps these wines good longer, but not indefinitely. Storing them in the fridge will keep the flavor better for longer—up to about a couple months, with sweeter varieties lasting longer than dry varieties.
Low-Proof Liqueurs and Aperitivi: Most liqueurs and aperitivi (a sub-category of red-hued, bittersweet Italian liqueurs) are high enough proof that between the alcohol and the sugar, they’ll last a long time at room temperature if they’re well sealed. However, some fruit liqueurs and a couple of aperitivi—notably including the popular Aperol—are below 15% alcohol by volume, which means they have the potential to spoil more easily at room temperature (though they’re still likely to last quite a while).
Wine: Whether or not you have one of those air remover thingies, tests have shown that one of the best ways to keep your open bottle of wine from turning sour is to stick it in the fridge, whether it’s red, white, or pink (just let red wine return to slightly below room temp before serving). Of course, it will still only last a few days, but if you haven’t finished it by then, it can’t have been that good of a wine to begin with!
