Beer nerds, listen up: Saturday, September 28th is Zwanze Day—the much-anticipated annual release of Cantillon Brewery’s celebrated Belgian sour, Zwanze—and Row 34 is one of only 28 US locations to snag a keg. This is seriously limited stuff that you’re absolutely not going to find anywhere else, so if you want a taste, stop reading now and click below for tickets. They’re $75 (you’re limited to two), and get you access to the private event, a special Zwanze glass, a 6oz pour of Zwanze for the global toast, and beer-friendly fare from the chef. There’ll be more Cantillon and other rare beers on draft for purchase. Seriously, though, just buy your tickets here before they sell out.
