Specs

Attenuation
70–85%
The share of sugars the yeast ferments out. Higher attenuation means a drier, stronger beer.
Optimal temp
20–27°C
68–81°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+
Finishes bone-dry
Carries the STA1 (diastaticus) gene, so it keeps eating sugars other yeast leave behind and finishes very dry. It's also a contamination risk: it can over-carbonate or gush if it crosses into other beers.
