If you’ve ever wondered what the alcoholic version of a butterbeer would taste like, you’ll soon have the chance to find out. A series of ongoing Harry Potter-inspired beer festivals has been traveling to cities across the U.S. over the past several months.

According to Rock Star Beer Festivals, which is organizing the event, Muggles and wizards alike will get unlimited samples of 20-plus beers. There will be plenty of adult butterbeer to go around, and for more daring souls, there’s Snape’s Lair of Secret Cider Potions. Is it actually cider, or could it be a polyjuice potion? Attendees will soon find out.

This fall, the festival will be coming to Portland, Oregon on September 13 and Fullerton, California on October 25. Tickets to the festivals can be purchased through Eventbrite or booked on Rock Star Beer Festivals’ Facebook page under the Events tab. Act fast, though, because tickets—which generally sell for $35 to $45 apiece—regularly sell out.

What else can you expect to see at such a magical event? Rock Star Beer Festivals says the venues hosting the festival will be “transformed into the Wizarding World of Harry Potter,” with guests being transported to the Great Hall, Diagon Alley, and, of course, the Leaky Cauldron. You’ll also get to snap photos with Hagrid and dance to music by the Sorceress Sisters and DJ Dumbledore. Just be careful not to drink and do magic, or you could end up having an accident à la Neville Longbottom.
