Hello, I'm Dr. Emily Carter, a chemist specializing in the properties of liquids and solutions. I've spent years researching the fascinating world of freezing point depression, which is exactly what's at play when we talk about alcohol's resistance to freezing.

Let's break this down. Freezing point depression is the phenomenon where the freezing point of a solvent (like water) is lowered when a solute (like alcohol) is added to it. This is a direct result of the solute interfering with the solvent's ability to form a crystalline structure, which is necessary for freezing.

Now, you're asking about the percentage of alcohol that won't freeze. This is where things get a little tricky. It's not as simple as saying "X% alcohol will never freeze." The freezing point of an alcohol solution depends on a couple of key factors:

* The type of alcohol: Different alcohols have different freezing points. For example, methanol freezes at -97.6°C (-143.7°F), while ethanol (the alcohol found in alcoholic beverages) freezes at -114°C (-173°F).
* The concentration of alcohol: The higher the concentration of alcohol, the lower the freezing point of the solution.

So, the percentage of alcohol required to prevent freezing depends on the specific alcohol and the surrounding temperature. To answer your question definitively, we need more information.

For example, if we're talking about ethanol and a typical freezer temperature of -18°C (0°F), then a **solution with a relatively high concentration of ethanol (around 40% or higher)** would likely not freeze. This is why hard liquors, which typically have an alcohol content of 40% or more, remain liquid even in freezing temperatures.

However, it's important to remember that even at high concentrations, **alcohol solutions can still freeze at extremely low temperatures**. And, as the concentration of alcohol decreases, the freezing point of the solution increases. A solution with a lower alcohol content, like wine or beer, could freeze at a higher temperature, even though it still contains a significant amount of alcohol.

I hope this explanation is helpful. If you can tell me more about the specific type of alcohol and the temperature you're interested in, I can provide you with a more precise answer about the percentage of alcohol that will not freeze.

You can't stick a margarita and gin martini into the freezer and expect them to come out the same way. The freezing point depends on the spirit's proof, or alcoholic concentration, which is is double its alcohol percentage. Vodka is usually about 80 proof, or 40 percent alcohol.read more >>
