Watch out, Summerfest cup-stacking: The Big Gig today revealed a new reusable souvenir cup – complete with discounts on beer refills – available for sale and for use throughout the three-weekend music extravaganza.

The plastic souvenir cup will be available for $5 at the Leinenkugel Bar located by the UScellular Connection Stage, Keg & Cask on the south end near the Briggs & Stratton Big Backyard and the Terrapin Trailer found on the lake walk. There, at any of those three spots, thirsty Summerfest fans can also nab a dollar off any draft beer refills with their cup. And when you're done for the day, you can wash the cup out at home and bring it back for more discounted refills each day throughout the Big Gig. 

The goal of the cup – beyond giving attendees both a souvenir to remember this year's Summerfest by and an excuse to enjoy even more tasty brews – is to help continue improving the festival's sustainability and eco-friendliness. 

“Partnering with Alderwoman Marina Dimitrijevic on this initiative to offer our fans a reusable cup for the festival speaks to our environmentally conscious patrons, while also helping us reduce waste and improve sustainability,” said Milwaukee World Festival Inc. president and CEO Sarah Pancheri, in a release.

“When we approached Summerfest to ask them to help us meet our city Climate and Equity Plan goals, their answer was an immediate yes,” added Ald. Marina Dimitrijevic, in the release. "'The World’s Largest Music Festival' just got even better and greener. If they can do it, we can all make changes that have huge impacts today."
