So, how long can you keep whiskey in a decanter? A few months, tops—unless you enjoy drinking air-infused, softly defeated whiskey. But here’s the twist: that’s actually fine. It’s like a slow, graceful fade.
Next time you pour a glass from that decanter, remember: it’s not “going bad.” It’s just taking a gentle nap. And when you wake it up, it might be a little sleepy, but it’s still whiskey—and that’s pretty darn cool. Cheers to that.
