Proprietor and mastermind Mitch Ermatinger, along with wife and partner, Whitney, opened Speciation Artisan Ales in Comstock Park in January 2017. They have since relocated Speciation to the Uptown neighborhood on Wealthy St in a 100-year-old auto garage.

Here’s everything you need to know about Speciation Artisan Ales, starting with the basics:

Beer

Speciation is known for its signature “wild” ales. Mitch Ermatinger refers to their beers as “rustic, wild beer that’s fermented with yeast from the environment.” Rather than traditionally inoculate their beers with lab-grown yeast, Speciation relies on what’s naturally floating around in the air (within the brewery) to make the magic happen.

Speciation also brews beer with single yeast cultures, including a lager, a pale ale and a stout. A Norwegian yeast strain called Kviek is used to ferment those beers, and they are available year round.

Prior to recent technologies that allow brewers to extract a single cell of yeast in order to harness its strain for consistency, Speciation’s brewing approach gives a nod to the way beer used to be made—one in which each batch, although perhaps the “same beer” on paper, is a beautiful anomaly from the last due to its reliance on trusting that Mother Nature will do her part where technology is generally relied upon.

Speciation takes a collaborative approach to its brewing. The brewery contracts with other breweries to brew unfermented beer for them. They’ve employed ArchivalCity Built Brewing Co. and the Mitten to handle this phase.

Speciation provides the recipe and the raw materials, and the specifications to the other brewery. That same day, the unfermented beer is turned back over to Speciation, where it spends the rest of its life fermenting, aging, and ultimately being packaged.

What makes Speciation’s beer particularly valuable is the blank canvas from which it starts.

Contained in a large 30-barrel and 50-barrel wooden foeder (approximately 1,000 gallons and 1,500 gallons, respectively), are their two distinct raw, house cultures used for the consistent base of their funky farmhouse ales and their sour/golden ales. It’s these two proprietary cultures that thread Speciation’s beers with its signature, underlying flavor profile foundation.

After being layered with fruit (locally sourced, seasons permitting) and other ingredients, about 75% of Speciation’s beers are laid to rest for months (or, even years) in an array of oak barrels.

What's on draft

Speciation offers three clean beers on tap with a rotating cast of five to six sour and wild ales. Dry cider is also available. Speciation's diverse menu also features “natural wines,” which use grapes grown with little to no pesticides or other additives and is spontaneously fermented by the yeast that resides on the grape skins, then aged in oak barrels.

The most popular drink is the Doc Flamingo's Neon Smoothie, which is a seltzer dosed with fruit puree to make an alcoholic smoothie. 

Pét-Nats (traditionally produced bubbly wine) and Piquettes (natural wine spritzer) round out this diverse menu.
