What is a distinguishing feature of German pils compared to Czech Lager?

The distinguishing feature of German pils compared to Czech Lager is indeed related to the yeast used in their production. German pils typically utilizes a different yeast strain than the one traditionally used for Czech lagers. The yeast for German pils is often a lager yeast that ferments at cooler temperatures, creating a clean and crisp profile. This choice of yeast plays a key role in defining the character of the beer, giving German pils a more pronounced hop bitterness and a slightly drier finish compared to Czech lagers, which tend to have a richer malt profile and softer mouthfeel.

Choosing different ingredients and brewing techniques contributes to the distinct flavors and aromas of each style. The other options either misrepresent the ingredients or characteristics of the beer styles or attribute differences that are not the primary distinction between the two. Thus, the yeast strain serves as an essential factor in differentiating German pils from Czech Lager.
