It’s a bird! It’s a plane! It’s a... Brewvolution! In celebration of the explosion of Philadelphia-area microbreweries, three of the newest collaborated on a special edition release called Brewvolution, set to debut at Philly Beer Week’s Opening Tap on Friday, June 1. Who’s making the brew, and what can drinkers expect to find when they sip?

Evil Genius Beer Company is a partnership between two Philly buds with a knack for crafting great recipes. Their standard labels are currently contract-brewed by Four Horsemen in Indiana, and include West Coat-style Evil Eye PA, German-style Good ‘n Evil and the summer-appropriate Witty Will. They first launched at Philly Beer Week in 2010, and began distribution last year.

Round Guys Brewing creates distribution beers in Lansdale, PA, with an on-site taproom, to boot. Again a partnership between two friends with a love for craft beer, this operation was founded in 2011. Offerings include Alpha Blackback (a black IPA), Original Slacker Ale (English-style) and rye-tinged Belgian tripel Fatbob XVII.

Prism Brewing Company has been around a bit longer than the previous two, founded by former filmmaker Rob DeMaria in 2009 as a contract brewery in partnership with the General Lafayette Inn. A year later, he found a permanent home in North Wales, PA, and now puts out a wide assortment of unique styles, including Bitto Honey IPA, Love is Evol (a strawberry jalapeno brown al) and Shady Blond, made with blood oranges (we recently had a chance to taste this and found it pleasantly refreshing — perfect for summer).

Back to the Brewvolution! The collab liquid — produced at Prism — is a Belgian black IPA that rings in at 7.6% ABV and 76 IBUs (relatively high on the International Bitterness Units scale). With hops from all three breweries in the mix, the aromas are unique and have a sharp, hoppy taste. The Belgian yeast rounds out the flavor, so also expect undertones of sweetness.

After Opening Tap, look for the draft-only beer at a Watkins Drinkery dinner on June 5, at the With Love Beer Garden on June 6 and at the official launch at Molly Malloy’s in Reading Terminal Market on June 7. That party will take place after the main market has closed, from 7–10 PM, so here’s your chance to explore RTM latenight, tasty brew in hand.
