Attenuation
70–75%
The share of sugars the yeast ferments out. Higher attenuation means a drier, stronger beer.
Optimal temp
18–21°C
64–70°F
The range where this strain ferments cleanly, without throwing off-flavors. Most brewers pitch near the low end.
Flocculation
Low
How readily the yeast clumps together and drops clear once fermentation winds down.
Alcohol tolerance
≈10% ABV
The rough ABV ceiling where the yeast stresses out and stops fermenting.
Genetic traits
Phenolics
POF+
Clove & spice
Throws phenolics — the clove and spice notes (4-vinyl-guaiacol) behind hefeweizens, witbiers, and saisons. Expect a spicy character, not a clean one.
Diastatic
STA-1−
Not diastatic
Does not carry the STA1 (diastaticus) gene. It attenuates normally, with no diastaticus over-attenuation or gushing risk.
