What is 30 proof alcohol?

* Proof is a measure of the alcohol content in a beverage. It's double the percentage of alcohol by volume (ABV).

* 30 proof means the beverage has an ABV of 15%.

* For comparison:

* Most beers are around 4-6% ABV (8-12 proof).

* Wine is typically 12-15% ABV (24-30 proof).

* Hard liquor ranges from 40-80 proof (20-40% ABV).

So, 30 proof alcohol is weaker than most beers and wines. It might be found in some low-alcohol beers or ciders, or even in some flavored malt beverages.
