Attenuation
70–80%
The share of sugars the yeast ferments out. Higher attenuation means a drier, stronger beer.
Optimal temp
22–28°C
72–82°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.
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+
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.
Same strain, other labs
Usually used in
IPA & Pale Ale
Common questions
- What is the Cerberus equivalent?
- A20 Citrus, OYL-200 Tropical IPA, and WLP644 Saccharomyces brux-like Trois — the same strain from other labs, the Trois (Saccharomyces 'brux-like') strain.
- What is Cerberus's attenuation?
- 70–80% apparent attenuation.
- What temperature should I ferment Cerberus at?
- 22–28°C is the recommended range.
- Is Cerberus diastatic (STA-1)?
- Yes. Cerberus carries the STA1 gene (S. cerevisiae var. diastaticus). It super-attenuates to a dry finish, and can over-carbonate or gush if it cross-contaminates other beers.
- What beer styles is Cerberus good for?
- IPA & Pale Ale.
