Can Blanco Tequila Expire?

Before you splurge on an expensive bottle of tequila, it is worth knowing whether or not your purchase will last once you have cracked open the bottle. Fortunately for tequila enthusiasts, tequila, along with most other hard liquors, will last indefinitely as long as it is stored properly. So go ahead and purchase that bottle of tequila you've been eyeing.

Getting to Know Blanco

  • Blanco tequila is tequila that is unaged and is typically bottled immediately after distillation or after it has had time to settle in stainless steel tanks for a period of up to four weeks. Some blanco tequilas may be aged for up to two months prior to bottling to achieve a smoother spirit. Blanco tequilas are also referred to as white, plata and silver, and, as its interchangeable names suggest, are clear in appearance.

Air Exposure Reduces Spirits

  • Once bottled, distilled spirits -- blanco tequila included -- cease to mature. This means that a spirit remains pretty much the same over time as the moment it was bottled, even after opening. However, once a bottle has been opened and exposed to the air, evaporation and oxidation will slowly begin to deteriorate the flavor and aroma of the tequila. The alcohol present in tequila is the substance most vulnerable to evaporation and oxidation. As the alcohol content diminishes, so too does the strength and flavor of the tequila. Drink tequila within a few months after opening, as that is when it will be at its best quality, suggests DoesItGoBad.com.

Making It Last

  • A bottle of blanco tequila will last indefinitely as long as it is stored properly, though the quality of the product will deteriorate over time. Store tequila in a cool, dry place away from heat. Ensure that the bottle is tightly sealed when not in use, as this protects against evaporation and oxidation. The bottle should be stored in an upright position, as spirits may eat away at cork seals over time. If you notice evaporation occurring in an unopened, corked bottle of tequila, the best course of action is to open the bottle and wrap the cork with plastic wrap to avoid further evaporation.

Drink Up

  • Blanco tequila shots are usually served with salt and a wedge of lime. However, a fine tequila should be enjoyed alone, without accompaniments. Blanco tequilas are primarily used for mixing cocktails like the margarita, the tequila sunrise, the paloma and the bloody Maria.
