What is the typical ABV range for Rhine Valley Ale/Kolsch?

The typical Alcohol By Volume (ABV) range for Rhine Valley Ale, which includes Kölsch, is indeed 4.4-5.2%. This range reflects the traditional brewing styles of the region, where Kölsch is a light, refreshing ale known for its delicate, crisp characteristics. It is intended to be easily drinkable, which is why the ABV is kept relatively low, making it both a popular choice for casual drinking and a staple in many beer gardens. The lower ABV also aligns with the beer's profile, often complemented by subtle fruity esters and a clean finish, which favors sessionability. In comparison, the other ABV ranges provided in the question fall outside the typical parameters for Kölsch-style beers, which further solidifies the correctness of the 4.4-5.2% range in this context.
