Brettanomyces lambicus by Wyeast 5526
Brettanomyces lambicus | Wyeast 5526 Yeast
High-Intensity Brett Strain for Deep Funk and Classic Lambic Character
Wyeast 5526 Brettanomyces lambicus is a powerful wild yeast strain that produces a pronounced “Brett character” featuring intense barnyard funk, horse blanket, and phenolic complexity. It is also known for its ability to generate high levels of esters, contributing bold tropical fruit notes like pineapple and mango when aged under the right conditions. Compared to Brettanomyces bruxellensis, this strain produces more aggressive flavors and acidity, making it ideal for Belgian lambic, gueuze, American wild ales, and sour blending projects.
Unlike traditional ale yeasts, Brettanomyces lambicus thrives during extended aging, slowly breaking down complex sugars and polysaccharides that Saccharomyces leaves behind. It is most commonly used during secondary fermentation and will continue to evolve over months or years, making it an essential tool for brewers aiming to build depth in sour or barrel-aged beer.
Key Characteristics:
- Species: Brettanomyces lambicus
- Flocculation: Low
- Attenuation: 70% - 85% (may continue beyond)
- Fermentation Temperature Range: 60°F - 75°F (16°C - 24°C)
- Alcohol Tolerance: 12% ABV
- Recommended Styles: Lambic, Gueuze, American Wild Ale, Brett Beer, Berliner Weisse, Oud Bruin, Barrel-Aged Sours
Why Choose Wyeast 5526 Brettanomyces lambicus?
- High Ester Production: Adds complex fruity notes like pineapple and mango alongside bold funk
- Stronger Than Bruxellensis: More intense acidity and phenolics make this strain ideal for sour programs and wild fermentation
- Perfect for Extended Aging: Slow fermentation leads to deep complexity in barrels or long-term bottles
Pair with Wyeast Yeast Nutrient for Robust Brett Activity
For healthy long-term Brett fermentations, especially in nutrient-depleted wort, we recommend using Wyeast Yeast Nutrient. It helps Brettanomyces lambicus perform more reliably over long aging cycles, supporting full attenuation and consistent funk expression.
Cold-Stored and Ready to Ferment
At SoCal Brewing Supply, all liquid yeast is refrigerated with 24-hour temperature monitoring to ensure optimal viability. We strongly recommend adding an ice pack for shipping yeast to protect it from temperature swings in transit. Ice packs help maintain yeast health during delivery, especially in warmer months or long-distance shipments.
