Brooklyn Brewery Mash will take partying to the streets with the East 6th Street Neighborhood Immersion. The fun starts at the Timberland and Brooklyn Brewery Trailhead, a pop-up bar, shop and official headquarters for the day. Guests will receive a bundle of coupons that get you lunch at a local hotspot, beers at a handful of favorite bars, and deals, discounts, classes and more throughout the neighborhood.
