What is the primary difference between kristalweizen and weissbier?

The primary distinction between kristalweizen and weissbier lies in the filtration process. Kristalweizen is a type of wheat beer that has undergone a filtration process rendering it crystal clear. This contrasts with weissbier, which typically has a hazy or cloudy appearance due to the presence of yeast and proteins that are not removed.

This clarity in kristalweizen is achieved through a thorough filtration that removes these particulates, resulting in a cleaner and clearer beer. The flavor profile can remain similar to that of weissbier, but the visual aspect is notably different. Therefore, the correct answer highlights the specific characteristic of kristalweizen that distinguishes it from the broader category of weissbier.
