Brettanomyces

Brettanomyces

Brettanomyces is a yeast that was originally thought of as a spoilage yeast. Known for it's barnyard, fecal, horsey, metallic or Band-Aid flavors, brett was unwelcome in most breweries. However, in some styles like Saison and Lambic these flavors add a layer of complexity to the beer.

Brett Blends

Manufacturer	Common Name	Notes
East Coast Yeast	ECY34	Twelve (12) different isolates of Brettanomyces exhibiting high production of barnyard "funk" and esters. Dryness, ripe fruit, and acidity will be encountered over a period of months and over time (>1 yr), may display gueuze-like qualities in complexity. Contains various isolates from lambic-producers, B. bruxellensis, B. anomala, B. lambicus, and B. naardenensis. For those who want the most from Brett yeast, whether a 100% Brett fermentation is desired or adding to secondary aging projects. Suggested fermentation temperature: 60-74 F. Attenuation high.
Yeast Bay	Beersel	not overly funky but there is a sweaty note hanging behind lemon and citrus fruits, nice blend of subtle funk and citrus/fruit
Yeast Bay	Brussels	similar to Beersel but with more funk in aroma and less fruit, complex barnyard character
Yeast Bay	Lochristi	Smells of Iris C2, probably the same, subtle blend with some delicate fruit, strawberry
