Tequila, like many spirits, does certainly not expire in the exact same way that perishable foodstuffs do, but it can undergo changes with time that affect its taste and quality. While tequila could be stored for long periods without spoiling, its flavor may evolve and diminish as time passes because of factors such as oxidation and exposure to light and heat. Generally, unopened bottles of tequila may be stored indefinitely without significant degradation in quality, so long as they're kept in an awesome, dark place away from sunlight and temperature fluctuations.

However, once a container of tequila is opened, its shelf life can vary depending on what it is stored and the conditions it is exposed to. Exposure to oxygen could cause the flavors of tequila to change as time passes, resulting in a loss of freshness and complexity. Additionally, if a jar of tequila is stored improperly, such as in a hot or humid environment, it could become susceptible to spoilage and degradation.

To prolong the shelf life of an opened bottle of tequila, it is essential to store it properly by keeping it tightly sealed and away from heat, light, and oxygen. Some does tequila expire enthusiasts also recommend storing opened bottles in the refrigerator to decrease the oxidation process and preserve the flavor. However, it's important to notice that storing tequila in the refrigerator may cause it to become cloudy, but this does not affect its quality or safety.

When it comes to taste, tequila can become smoother and more calm with age, particularly if it's aged in oak barrels. However, prolonged experience of oxygen may also cause the flavors of tequila to become dull and flat, leading to a loss of complexity and character. Consequently, it is generally recommended to take opened bottles of tequila within a couple of months to a year for optimal flavor and quality.

Ultimately, while tequila does not expire in the standard sense, it could undergo changes with time that affect its taste and quality. By storing tequila properly and consuming it in just a reasonable timeframe, you are able to make sure that you enjoy the full flavor and character of the beloved spirit.
