What is the percentage of beer?

The percentage of alcohol in beer varies widely, depending on the style and brewing method. Most beers fall between 4% and 6% ABV (alcohol by volume), although some specialty beers may have an ABV as low as 0.5% or as high as 20%.

In the United States, the average ABV of beer is about 5%. In the United Kingdom, it is about 4%. In Germany, it is about 5%. In Belgium, it is about 6%.

The strength of beer is typically determined by the amount of fermentable sugars that are present in the wort before fermentation. The higher the sugar content, the stronger the beer will be.

Other factors that can affect the strength of beer include the yeast strain that is used, the fermentation temperature, and the length of time that the beer is fermented.
