Here’s where it gets personal for your drink of choice. Most alcoholic beverages aren’t pure alcohol—they’re a mix of ethanol and water. And water, as we know, freezes at 32°F (0°C).
This mix creates a freezing point depression. Basically, the alcohol acts like a grumpy chaperone, telling the water molecules, “Hey, don’t you dare freeze yet!” The more alcohol in the bottle, the lower the freezing point.
A light beer (around 5% ABV) will freeze at about 28°F (–2°C). That’s why you can sometimes find a slushy beer left in the car overnight. But a strong bourbon (40% ABV) won’t freeze until around –10°F (–23°C).

What about that slushy effect?
Ever put a bottle of wine in the freezer and come back to find a cloudy, slushy mess? That’s because the water freezes first, pushing the alcohol into a liquid core. The ice is mostly just frozen water—with the alcohol and flavor compounds left behind.
This isn’t just a party trick. It’s the same principle behind “freeze distillation” (or “Jägermeister ice shots”). You freeze a drink, pour off the unfrozen liquid, and—bam—you’ve concentrated the booze and flavor.
So your freezer is basically a gentle laboratory for separating water from alcohol. Kind of cool, right?
