Saccharomyces brux-like Trois | White Labs WLP644 Yeast
Saccharomyces brux-like Trois – WLP644 from White Labs
Bright Tropical Fruit and Bold Juiciness from a Unique Sacch Strain
Originally believed to be a Brettanomyces yeast, White Labs WLP644 Saccharomyces brux-like Trois has been reclassified as a pure Saccharomyces strain. What hasn’t changed is its incredible ability to produce bright, tropical fruit character and a soft, juicy mouthfeel that brewers love in modern IPAs, saisons, and specialty ales.
This yeast offers low phenolic expression, meaning it ferments clean without spicy or clove-like notes, while delivering layers of pineapple, mango, and guava aromas. It performs best with a free-rise fermentation and plenty of oxygenation, enhancing ester production and creating expressive, fruit-forward beers.

Why Choose WLP644 Sacch Trois:

Our Commitment to Yeast Health
At SoCal Brewing Supply, we take yeast storage and viability very seriously. We ensure yeast is always stored under optimal conditions, with 24-hour monitoring of refrigerator temperatures to prevent spikes that could negatively impact yeast health.
For liquid yeast orders, we recommend shipping with an ice pack and insulated envelope to ensure your yeast arrives in top condition. It's normal for ice packs to melt during transit; their purpose is to protect the yeast from extreme temperatures caused by external weather conditions.
