Genetic traits

Phenolics
POF−
Ferments clean
Phenolically clean (POF-negative). No clove or spice, so malt, esters, and hops come through unmasked. The norm for American and British ales and most lagers.
Diastatic
STA-1−
Not diastatic
Does not carry the STA1 (diastaticus) gene. It attenuates normally, with no diastaticus over-attenuation or gushing risk.
