Versatile, crisp, malty profile, light esters and a wide fermentation range, German Lager I is thought to be the world’s most used lager strain and can produce a convincing lager at ale temperatures. Fermenting in the low temperature range (45-55° F), it maintains a more crisp profile. Temperatures higher in range (65-68° F) bring out slightly heightened esters. Rest for diacetyl.
Attenuation: 73-77%
Flocculation: Medium-low
Optimum Ferm Temp: 45–68° F (7–20° C)
Alcohol Tolerance: High up to 9%
