At Speciation Artisan Ales, we take an evolutionary approach to brewing by using wild microbes to experiment with the possibilities of craft beer.

The results are delicious, high-quality and ever-changing beers that reflect nature’s creativity and diversity. The name Speciation comes from the scientific term describing how biological variations in nature create new species over time, much like the evolution of our beers.

Speciation is a production brewery with a 10bbl/batch capacity. We do not currently have a tasting room. Instead we do monthly bottle releases on the second Saturday of every month. We also have very limited distribution of bottles and kegs in the Grand Rapids Area, and limited distribution of bottles in Detroit metro area.

Speciation Artisan Ales is founded by husband & wife team, Mitch and Whitney Ermatinger.  Speciation is a mixed-culture fermentation brewery specializing in wild ales that have been bottle conditioned and keg conditioned. We intend to provide high-quality sour beer, farmhouse ales, and spontaneously fermented beers to West Michigan.

Mitch formerly brewed at Denver-based microbrewery Former Future Brewing Company and has had the privilege to develop his knowledge about wild fermentation working under James Howat at Black Project Spontaneous and Wild Ales. Former Future/Black Project won bronze medals at the GABF for wild beer in 2014 and 2015, and their beer Jumpseat was rated as world class by BeerAdvocate Magazine.

In 2016 Harmony Brewing Company hired Mitch to help them start a barrel aged rustic/farmhouse program at Harmony Hall. Many of their sour creations are on tap at any given time.

Mitch started his career in beer at O'Connor's Home Brew Supply.
