Krausen
Krausen is a foamy layer that forms on top of beer during the fermentation process. In brewing, this term is important because it indicates active fermentation and healthy yeast activity. Brewers monitor the krausen to track fermentation progress and ensure quality. The term appears in both traditional brewing and modern craft brewing contexts. When you see this on a resume, it often indicates hands-on brewing experience and understanding of fermentation processes.
