==Brettanomyces dominance==
[[file:Brettanomyces_micrograph.jpg|thumb|right|A micrograph of Brettanomyces sp.]]
Brettanomyces inherits the role of most prominant yeast genera from Saccharomyces around 8 months, and continues consuming sugar in the wort. Final attenuation can reach over 80% in lambic through the continued action of Brettanomyces, which is often referred to as "overattenuation" or "superattenuation". This is greater than is usually possible with Saccharomyces alone, as Brettanomyces is able to metabolise sugars that Saccharomyces cannot, generally known as "dextrins".
