Does Alcohol Lose Potency If Left Open

Does Alcohol Lose Potency If Left Openの概要と注目ポイントを一挙に解説しました。

Hard liquor is more resilient because it’s, well, harder. Higher alcohol content means less opportunity for evaporation to make a dent. A bottle of vodka left open for a year? The alcohol loss is probably under 5%—basically a rounding error. But the flavor? If it’s a cheap vodka, you might not even notice because it already tastes like rubbing alcohol. Congratulations, you’ve upgraded to quality cleaning supplies.

But for something like a fine Scotch or bourbon, leaving it open for months can dull the nose and the finish. The alcohol won’t lose much kick, but the experience will. So if you’re saving a special bottle for a rainy day, put the cork back in. Show it some respect.

Here’s a Fun Experiment (Don’t Actually Do This)

Imagine two identical glasses of wine: one you leave open for a day, one you pour fresh. The next day, taste them. The open one might taste a bit “stale,” but the alcohol content? Identical. Your head won’t know the difference, but your palate will file a complaint. That’s the takeaway: alcohol is a survivor, but flavor is a delicate flower.
