Experimentation is one of our top goals here at Archetype Brewing. It helps us discover new ways of utilizing the ingredients we know so well...and it's fun. In the spirit of pushing boundaries, we've delved into using Brettanomyces and mixed fermentation for our beers.


 

What is Brettanomyces ("Brett")?

Most commonly, beers are made with a yeast strain called Saccharomyces, but in recent years, an old strain of yeast has been rediscovered by brewers and is starting to make a comeback. Brettanomyces was discovered and isolated in 1889, and used primarily in traditional European beers. While it takes longer to ferment (turn the sugars into alcohol), it lends a bright, funky flavor, with floral notes and a dry complexity that we really love.

 

 

What does "mixed fermentation" mean?

Mixed fermentation simply means that we use both Saccharomyces and Brettanomyces yeasts to ferment the beers. Most of our mixed fermentation beers undergo fermentation with the Saccharomyces first, and then are barrel-aged with Brettanomyces for a time before being kegged and served. The secondary fermentation with Brett adds even more complexity and flavor to the beer, and lowers the content of residual sugar.
