Storing tequila in the freezer?
I doubt that storing tequila in your freezer will make it taste better, but under certain conditions it could preserve the great taste of tequila. Storing your liquor in general in a freezer is not a bad idea at all, but is only possibly necessary at certain times.
For the most part, there’s no need to refrigerate or freeze liquor whether it’s still sealed or already opened.
Hard liquors like vodka, rum, tequila, and whiskey; most liqueurs, including Campari, St. Germain, Cointreau, and Pimm’s; and bitters are perfectly safe to store at room temperature. Essentially every liquor mentioned in this Bar Cart post on stocking your home bar with the notable exception of already-opened vermouth can and should be stored without refrigeration.
That notable exception of vermouth I mentioned above is because vermouth is actually a fortified wine. And like regular wine, it will eventually oxidize, so it needs to remain in the fridge once it’s been uncorked. Vermouth and dessert wines like vin santo, ice wine, and the like thankfully have a longer refrigerator shelf life than their regular wine counterparts, and won’t turn vinegary and sour in the span of a few days. But they will slowly start to lose their nuances of flavor, and after a few months—six, max—they’re probably goners. - How Should I Store My Booze?
Like almost any other alcohol (besides some liqueurs), tequila should be stored in a cool and dry area. Therefore, the pantry seems to be the best possible choice, but if you don’t plan to open the bottle within the next few weeks or months, you can store it in the cellar (if there’s not enough space in the pantry). After opening the bottle please remember that you should always keep the bottle tightly sealed when not in use. Don’t ever store it with a pourer on or without its cap.
Tightly sealed bottle ensures two things. First – any impurities won’t be able to find their way into the bottle. Second – if the bottle stays opened without its cap, the liquid evaporates quicker than when it’s sealed. Because alcohol evaporates quicker than water, your tequila will slowly become milder with time (after opening the bottle for the first time).
When the bottle is less than half full and you won’t consume the rest of its contents within a couple of weeks, it’s a good idea to pour the liquid into a smaller bottle. More air in the bottle equals faster evaporation and oxidation, both of them causing the quality of tequila to slowly deteriorate.
The shelf life of tequila is indefinite if the seal remains undamaged. If not consuming your tequila in a relatively short time I would not hesitate to put it in the refrigerat
First thing that not everyone is familiar with is that spirits, unlike wines, don’t age after being bottled. That means that storing tequila for years won’t make its taste better. When it comes to shelf life of tequila, it’s basically indefinite, as long as its seal isn’t compromised. If you store an unopened bottle in the pantry for quite a few years now, you can be almost sure that it’s fine now and it should be of great quality. After the bottle is opened for the first time, it’s recommended to drink tequila within a couple of months, when its quality is still at its best.
With freezing temperatures be sure your bottles will not explode.
The average home freezer is about -17 C (-1 F). This is cold enough to freeze your food and ice, but not cold enough to freeze the average bottle of 80-proof liquor.
