What Is Tequila?

Tequila is an agave-based Mexican alcoholic liquor. It undergoes distillation, which entails heating and then cooling to a liquid condition with a greater alcohol concentration.

How to Tell if Tequila Is Bad

It is difficult to figure out whether your tequila is bad because, unlike foods that can change color easily, this liquor must be tasted or smelled to prove it has gone amiss.

1. Poor liquor quality

Before drinking a bottle that has been opened and stored for a long time, take a closer look at the liquid (assuming there aren’t any contaminants in the bottle), smell it, and taste a bit of it to see whether it’s awful. If it doesn’t look right, smells funny, or tastes bad, throw it out.

2. Examine the label

Any product branded “tequila” should provide the consumer with some basic information about its quality and legitimacy. If the bottle does not say the origin of the alcohol, or the location of the makers, or if there is no certification stamp, you should avoid it.

How to Preserve Tequila

To avoid a reduced shelf life and keep the greatest quality, store your liquor with a firmly covered lid. This will keep the tastes and sensations from deteriorating due to oxidation. More oxygen, in other words, can cause the flavor of whiskey, vodka, or tequila to diminish.

1. An unopened bottle of tequila

  • You should correctly store liquor at a temperature of 50-55°F (10-13°C) in a liquor cabinet tuned to the proper temperature for the best liquor storage temperature.
  • If you live in a hot region, it’s best to keep your booze in a dark cabinet since the heat from the sun might degrade its quality.
  • If you don’t have access to a liquor cabinet, keep your liquor in a cold, dark location away from heat and light.
  • Wide temperature changes (such as keeping it near a window) might degrade the flavor of your tequila.

2. An Opened bottle of tequila

  • Once you have an opened bottle of tequila, keep the liquor somewhere it will not be exposed to air, light, or contamination.
  • Even if liquor has been opened, it should be kept in a cold, dry place away from direct sunlight to ensure that the tastes and smells remain true to the quality.
  • Also, make sure the cork top on the bottle is firmly secured since this might cause your alcohol to lose its purity and flavor over time.
  • If you only drink booze on special occasions or are a light drinker, it’s also a good idea to pour liquor into smaller corked bottles after drinking more than you predicted.
  • Otherwise, the combustion will be accelerated by putting the liquor in a bottle with more air in it.

Does freezing tequila ruin it?

How do Mexicans drink tequila?

Tequila is traditionally consumed straight in Mexico, without the addition of lime or salt. Drinking good alcohol with a side of sangria, a sweet-tart, and a spicy cocktail prepared from oranges, tomato juice, and hot chili is popular in some locations.


Tequila is a famous worldwide alcoholic beverage known for its intense sting when consumed as well as its distillation and -most importantly- its long shelf life when stored properly.

However, if opened and not used within a year, the liquor can go bad. On the other hand, an unopened bottle will keep indefinitely even after the end date.

Furthermore, alcohol does not have any worms and does not change color when spoiled. The smell will usually inform you that something is wrong.
