The Ultimate Guide to Liquor Shelf Life: How Long Does Alcohol Last?

Every home bartender wonders about the shelf life of their spirits. Whether it’s an untouched bottle of crème de violette or an aged single malt waiting for a special occasion, it’s natural to question how long these bottles will last. The shelf life of liquor varies widely depending on the type and how it’s stored. Here’s a quick rundown:

Liquor Shelf Life Quick Facts:

    • Unopened bottles of liquor can last indefinitely if stored properly: away from sunlight, tightly sealed, and at room temperature.
    • Opened bottles of distilled spirits (like whiskey and gin) won’t expire but may start to taste “off” after 1–3 years.
    • Liqueurs, once opened, typically last 6 months to a year.
    • Vermouth and other wine-based spirits should be refrigerated and consumed within 6–8 weeks after opening.

Detailed Shelf Life and Storage Tips:

Distilled Spirits:

    • Unopened: Indefinitely, if stored properly.
    • Opened: 1–3 years, but taste may deteriorate over time due to exposure to air (oxidation), light, and heat. Store in a cool, dark place.

Liqueurs and Amaro:

    • Opened: 6 months to a year. Sugar acts as a preservative, but crystallization may occur. Keep sealed and store in a cool, dark place.

Vermouth and Wine-Based Spirits:

    • Unopened: Can be stored at room temperature.
    • Opened: Refrigerate and use within 6–8 weeks. These products spoil faster due to their wine base.

Storage Best Practices:

    • Avoid Sunlight: Direct light can cause heat build-up, accelerating evaporation and oxidation.
    • Steady Temperature: Store in a stable environment, ideally around room temperature.
    • Upright Position: Unlike wine, liquor should be stored upright to prevent the alcohol from eroding the cork, which can lead to faster oxidation.

Table of Liquor Shelf Life:

Type of Liquor Unopened Shelf Life Opened Shelf Life
Whiskey Indefinite 1-3 years
Vodka Indefinite 1-3 years
Gin Indefinite 1-3 years
Rum Indefinite 1-3 years
Tequila Indefinite 1-3 years
Liqueurs (e.g., Amaretto, Bailey’s) Indefinite 6 months to 1 year
Vermouth Indefinite 6-8 weeks (refrigerated)
Wine-Based Spirits Indefinite 6-8 weeks (refrigerated)

Tips from Experts:

    • Oxygen: Once a bottle is opened, oxygen starts affecting the spirit. Ethanol evaporates quicker than water, reducing proof over time.
    • Heat: Avoid storing bottles in warm places. Heat can cause expansion, potentially forcing corks out and allowing more air in.
    • Cork Care: For bottles with natural corks, wet the cork once a year by flipping the bottle briefly to prevent drying out.

Remember, while spirits may not spoil in the way food does, their quality and taste can diminish over time. Proper storage ensures you get the most enjoyment out of every sip. Cheers!
