Brandy is a distilled spirit made from fermented fruit juice. The base is usually wine, but brandy can be made from other fruits. The U.S. Alcohol and Tobacco Tax and Trade Bureau requires brandy to contain at least 40 percent alcohol by volume, or 80 proof. There is no maximum alcohol content.

To determine brandy's freezing point, view it as an alcohol solution. The more alcohol in solution, the lower its freezing point. Brandy containing the minimum required alcohol content of 40 percent by volume -- 80 proof -- will freeze at -10 degrees Fahrenheit. Brandy containing 50 percent alcohol by volume, or 100 proof, will freeze at -25 degrees Fahrenheit. The higher the alcohol content, the lower the freezing point.
