Does Alcohol Freeze

So, there I was, a few years back, at a friend's house, it's freezing outside, and I'm trying to make a round of hot toddies to warm us up. I'm pouring in the whiskey, lemon juice, honey, and hot water, giving it a good stir, and then I notice something weird. The whiskey isn't freezing, even though the water's steaming. I turn to my friend, eyebrows raised, "Why isn't this freezing?" I ask, like I've just discovered the meaning of life. He looks at me, deadpan, "Because it's alcohol, dude. It doesn't freeze."

And that, my friends, is how I learned that alcohol doesn't freeze. But why? Let's dive in, shall we?

Alcohol's Freezing Point: A Mystery?

You might be thinking, "But water freezes at 0°C (32°F), and alcohol's mostly water, right?" Well, yes and no. Alcohol, or ethanol to be precise, has a lower freezing point than water. It's around -114°C (-173°F). But here's the kicker, when you mix alcohol and water, the freezing point of the mixture goes up. This is because water molecules attract each other more than they do with ethanol molecules. It's like they're holding hands, making it harder for them to move around and freeze.

So, when you mix them, the freezing point of the mixture is higher than that of pure water. This is why your hot toddy doesn't freeze, even though the water in it would on its own.

But What About Those Ice Cold Martinis?

You might be wondering about those ice-cold martinis you see in movies. How do they stay liquid when it's freezing outside? Well, first off, it's important to note that those martinis are probably not as cold as the North Pole. They're usually around -10°C to -15°C (14°F to 5°F), which is cold, but not freezing by alcohol standards.

What Is the Freezing Point of Alcohol?

Secondly, alcohol doesn't freeze at those temperatures because it's usually mixed with other stuff. Like water, sugar, or other spirits. These mixtures have higher freezing points. It's also why you can make ice cream at home. The sugar in the ice cream mixture raises its freezing point, preventing it from turning into a solid block of ice.

So, Does Alcohol Freeze? Sort Of.

In a way, yes, alcohol can freeze. If you put it in a really cold environment, like liquid nitrogen (-196°C or -321°F), it will freeze. But in everyday temperatures, it's not going to happen. Unless, of course, you're talking about the kind of freeze that happens after one too many shots. But that's a different story.

And there you have it, folks. Alcohol doesn't freeze in your drinks because it's a sneaky little molecule that doesn't like to play by the rules. Isn't science wonderful?
