Alcohol doesn’t always last forever. Learn the signs your liquor has gone bad and how to store it safely for maximum freshness and taste.

When it comes to alcohol, many people assume that it lasts forever. While spirits like whiskey, vodka, rum, and gin are more shelf-stable than beer or wine, they can still deteriorate in quality if not stored properly. Knowing how to identify when your alcohol has gone bad—and how to store it correctly—can help you enjoy a safe and satisfying drinking experience.

Does Alcohol Really Expire?

The truth is, pure distilled spirits (over 40% ABV) don’t technically “expire” in the way food does, since high alcohol content prevents microbial growth. However, they can lose flavor, aroma, and overall drinking quality over time. Lower-ABV drinks like wine, beer, liqueurs, and mixers are more perishable and do have expiration dates.

Signs Your Alcohol Has Gone Bad

1. Change in Smell

♦ If your liquor smells sour, metallic, or simply “off” compared to how it normally should, it’s likely gone bad.

♦ Wines may smell like vinegar, while beers can smell skunky or stale.

2. Change in Taste

♦ Alcohol that tastes flat, dull, or has a strange aftertaste is a clear sign of degradation.

♦ Sweet liqueurs may taste syrupy or bitter if sugar crystallization has occurred.

3. Change in Appearance

♦ Cloudiness, floating particles, or discoloration can indicate spoilage or oxidation.

♦ Wine may turn brownish or brick-red when it’s past its prime.

4. Loss of Strength

♦ Spirits left open too long can evaporate, reducing alcohol content and leaving behind a weaker taste.

♦ Cocktails pre-mixed and stored too long often lose potency and freshness.

5. Mold or Sediment

♦ Rare in high-proof spirits, but possible in liqueurs, mixers, or low-ABV products once the seal is broken.

♦ If you see mold, discard immediately.

How to Store Alcohol Safely

✔ Keep It Sealed

Always tightly close the bottle after use to prevent oxidation and evaporation.

✔ Store Upright

Liquor bottles should be stored standing up to avoid long-term cork contact, which can damage both cork and flavor.

✔ Avoid Sunlight

Direct sunlight can break down alcohol molecules and cause fading in color and taste. Store in a dark cabinet or bar.

✔ Stable Temperature

Extreme temperature shifts can ruin alcohol quality. Aim for cool, consistent storage (15–20°C).

✔ Refrigerate Certain Types

♦ Beer, wine, and cream-based liqueurs should be refrigerated after opening.

♦ Spirits (whiskey, vodka, rum, gin) can be stored at room temperature but may last longer in cool conditions.

✔ Mind the Shelf Life

♦ Unopened spirits: Indefinitely good if stored properly.

♦ Opened spirits: Best consumed within 1–2 years for peak flavor.

♦ Beer: 6–12 months unopened, a few days once opened.

♦ Wine: A few years unopened (depending on type), 3–7 days once opened.

♦ Cream liqueurs: 1–2 years unopened, 6 months after opening.

Final Thoughts

While alcohol rarely becomes harmful in the way spoiled food does, its quality can decline if neglected. Always check for changes in smell, taste, or appearance before pouring yourself a drink. By storing your alcohol in the right conditions, you’ll extend its shelf life and enjoy every sip at its best.
