Mass Extinction Imperial Stout (Stainless-Steel Aged)
Twin Leaf Brewery

Twin Leaf Brewing is teaming up with the Asheville Museum of Science (AMOS), previously known as the Colburn Science Museum, to create two beers that will raise funds for the museum’s current spotlight campaign. The collaboration supports AMOS’s expansion into the Wells Fargo building adjacent to Pritchard Park, a move which will almost double its exhibit and classroom space and allow for expanded science education programming in Western North Carolina.

The collaboration beers are two versions of imperial stout. The more traditional stout, Mass Extinction, was aged in stainless for eight months. The second beer, which carries the same namesake, was barrel-aged in bourbon barrels for twenty months. Barrel-Aged Mass Extinction boasts added flavors of vanilla and tannic bitterness due to the barrels. In addition to the same name, both beers have a T-rex on their label, an image that has become symbolic of the museum, as they have acquired a juvenile “cousin” to the T-Rex for their exhibits.
