Which of the following beer styles would you expect to have the highest alcohol content?

Wee Heavy is known for having the highest alcohol content among the listed beer styles. This style of beer, originating from Scotland, typically features a rich, malty character with a significant proportion of alcohol, often ranging from 6% to 10% ABV, and sometimes even higher. The brewing process for Wee Heavy involves using a larger amount of malt, which contributes to both the flavor and the alcohol content.

In contrast, the other styles listed have generally lower alcohol content. Irish Stouts typically range from about 4% to 5% ABV, while Best Bitters and British Brown Ales generally fall within the 3% to 5.5% range. These lower alcohol levels are reflective of their lighter, more sessionable nature. Thus, among the options presented, Wee Heavy stands out distinctly due to its higher malt concentration and resultant elevated alcohol levels.
