Attenuation
75–80%
The share of sugars the yeast ferments out. Higher attenuation means a drier, stronger beer.
Optimal temp
18–30°C
64–86°F
The range where this strain ferments cleanly, without throwing off-flavors. Most brewers pitch near the low end.
Flocculation
Medium
How readily the yeast clumps together and drops clear once fermentation winds down.
Alcohol tolerance
≈15% 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.
