Groundwork Coffee is an LA-based roaster that has expanded to Portland and introduced a "Brewers' Series" of collaboration beers, but the latest is a hard cider: Revere nd Nat's "Electric Red" Groundwork Coffee Sour Cherry Cider. Nat's used Groundwork's organic "Bitches Brew" signature blend coffee for Electric Red and will be launching it at the  Reverend Nat's Hard Cider Tasting Room on Thursday, May 31st.More from a press release:As Groundwork has done with their previous "Brewers' Series" releases, for every "Electric Red" cider sold at Reverend Nat's Tasting Room during its first week on tap, May 31st to June 7th, $1 will be donated to the  Café Femenino Foundation, an independent nonprofit organization that funds community betterment grant requests proposed and managed by women in coffee-producing regions around the world. The name "Electric Red" describes the color of this vibrant sour cherry cider, and is also a reference to aging the cider on Groundwork's " Bitches Brew" signature blend coffee. Groundwork's Bitches Brew is named after American jazz musician Miles Davis' Grammy Award-winning record - one of jazz's greatest albums and a progenitor of the jazz rock genre - where Davis broke boundaries of jazz by featuring several electric instruments."Electric Red" Tasting Notes: Nice deep palate. Enticing and assertive aromas of dark chocolate, cherry, and coffee roast smokiness, subtle caramel notes. A tart granny-apple base blended with copious amounts of sweet and tart cherry juices, aged on Bitches Brew ground coffee...imagine a semi-sweet dark chocolate-cherry cake, drizzled with a dark-roasted coffee finishing glaze, ending with a kick of ghost-chili spice surprise to round out the profile. Try this exclusive collaboration coffee cider at  Reverend Nat's Tasting Room, open daily:  1813 NE 2nd Ave, Portland, OR 97212."Electric Red" is the third collaboration release in the Groundwork "Brewers' Series". Every collaboration beverage features a different Groundwork coffee roast chosen personally by a brewer, then brewed into a unique style that's not typically combined with coffee. The first collaboration of the series was a Coffee and Cream Ale made by Stormbreaker Brewing called"MOCABE Lo Sabe" featuring Groundwork single origin coffee from Mexico's  MOCABE Organic Farmer Co-Op, and the second was a "Wau, Nessie!"
