Alcohol By Volume: This is fairly straightforward, it is the alcohol percentage by volume in the beer.

Attenuation: This value represents the apparent attenuation or how much sugars the yeast converted into alcohol. The range for beer is typically between 65%-85% but is really dependent on the yeast strain. The higher the value the less residual sweetness.

Alcohol By Weight: Percentage of alcohol by weight of the beer.

Calories: Total calories per a 12 ounce beer.
