What is one characteristic of a Kölsch beer?

Kölsch is unique in its fermentation process, which utilizes top-fermenting ale yeast that is fermented at a cooler temperature than typical ales but warmer than lagers. Although some might confuse it with lager due to its clean and crisp characteristics, Kölsch is primarily an ale, distinguishing itself within the category. The beer is noted for its subtle hop profile, which tends to be low to moderate in bitterness, thus contrasting with more bitter styles. Furthermore, Kölsch traditionally incorporates a mix of malt, often including barley and sometimes wheat, but it is not exclusively brewed with barley.

Overall, highlighting the use of lager yeast aligns with the definition of Kölsch, as it employs a specific fermentation technique resulting in its distinctive flavor profile.
