Darwinians, rejoice. There's a new collaboration coming from Flying Dog and Evolution. The two Maryland breweries have a joint release that's going to keep evolving over the next year. From a press release:

A key mechanism of evolution, Natural Selection is one of the cornerstones of modern biology and now, Maryland craft beer.

Today, Flying Dog Brewery and Evolution Brewing Company announced the release of Natural Selection Ale, a three-part collaborative beer.

The Maryland breweries will launch the first Natural Selection release, Genus One, in March. A stock ale, Genus One has caramel and brown fruit notes that mingle with hints of roast, chocolate, and toast.

Then, a common descent will occur as each brewery brews a second batch of Natural Selection with Flying Dog dry hopping its version (Genus Two) and Evolution barrel aging theirs (Genus Three).

“What appealed to us is the collaborative nature of the stock beer and how the two other releases play off of each brewery’s strengths,” Flying Dog Brewmaster Matt Brophy said. “We released our first double dry hopped beer last year and have been experimenting with cutting edge hop varietals in our series of Single Hop Imperial IPAs for the past two years.”

"We've had a lot of fun at Evolution designing beers to pair with different barrel types and this is an opportunity to expand on that experience,” Evolution Brewmaster Geoff DeBisschop said. “Creating a beer that can express barrel character in our release while complementing dry-hopping in the Flying Dog version was a great challenge and I'm looking forward to the results."

Natural Selection Ale: Genus One will premiere during the Craft Brewers Conference in Washington, DC on draft only. Genus Two and Genus Three will be released in October. All three releases will only be available in mid-Atlantic markets.
