Flavor Behavior Classic hefeweizen esters and phenols — banana, clove, and sometimes bubblegum. The balance shifts noticeably with fermentation temperature.

In Practice Low-flocculating strain that stays nicely suspended for that traditional hazy hefe look. Warmer ferments (70°F+) and slight under-pitching push banana, cooler ferments emphasize clove. Reliable for traditional German wheat styles.

Pitching 100 mL homebrew pack for 5 gallons up to approximately 1.060 OG. Direct pitch liquid culture.
