Does Alcohol Evaporate? See The Truth

We get this question a lot. Does alcohol evaporate? From the bottles? From the decanters too? Let’s have a look at this frequently made inquiries today! We actually want to talk a bit about barrel aging, too. We’re Kentucky bourbon buffs, so we feel the need.

And of course, let’s discuss our decanters. We are pumped to introduce you to our amazing lineup and one of its best features. Ready to get to know alcohol up-close and personal?

(Our answer to that is always YES.)

So, Does Alcohol Evaporate?

First, we’d like to take this opportunity to mention the “angel’s share,” since we’re on the topic of evaporation. We have a lot of liquor newbies in our circle, so we’re always looking for ways to help them learn.

The “Angel’s Share”

When wine or spirit is aged in barrels, some of the liquid evaporates. In the process, that liquid disappears into the heavens, so to speak. Hence, “angel’s share.” Several factors contribute to this — like the size of the barrel, temperature/climate, how it’s stored, and the spirit’s age so far.

As you might guess, warm and humid climates see more evaporation of alcohol. If you have a drier climate, water evaporates, strengthening the alcohol.

Smaller barrels see more alcohol evaporation. And if barrels are stored above ground, that angelic air moves around the barrel. You know what that means…more alcohol evaporates.

Further, the alcohol evaporates more slowly as a spirit ages.

“Devil’s cut” refers to the alcohol absorbed by the barrel itself. Here’s a quick video about the tradeoff.

Does Alcohol Evaporate from Its Bottle?

Over time, your bottles can lose their alcohol content. It’s true. Many distilleries will tell you: when whiskey and such is in the barrel, it’ll lose around 4 percent of its alcohol in a year’s time. On average, bottles lose nearly 2 percent per year. If you’re keeping a special bottle on hand, after a decade, that bottle has likely lost 20 percent of its original alcohol content.

Some people say, Oh well, it’s all a natural part of the process. We say it doesn’t have to be that way.

Does Alcohol Evaporate from a Decanter?

It can. And it does. UNLESS… you have the right decanter.

We’re Louisville kids here at Prestige. We DO NOT play when it comes to our liquor–particularly our bourbon. Before our company began, we noticed a lack of unique decanters. Decanters were boring. So, we decided to fix that with some amazing creativity. But we also vowed to make decanters that would preserve the good stuff.

We’re certainly not angels, but we do like our share. And we like it protected. We know you prefer this, too. Have a look at our striking Tomoka Gold Decanter in action right here. If you don’t have a tight seal, your alcohol will evaporate. Ugh. It makes us cringe. Which is why we use a ground glass stopper on our decanters. This prevents evaporation. Quality materials lead to years of quality liquor. Whatever you decide to store in our decanters will be safe.

Hand-blown glass decanters aren’t wooden barrels. And with our signature seal, no air will damage your favorite pours.
