Dock Street Brewing Co. is the city’s oldest operating microbrewery, serving thirsty Philadelphians on the corner of 50th and Baltimore Avenue in Cedar Park since 1985, and on Sunday, May 6 they’re hosting their biggest and rarest bottle release ever. Over the past year, brewmaster Scott Morrison and team have brewed a series of unique one-offs, including a series of Abbey-style ales, and a dozen cases of each have been aging in their cellars in anticipation of this epic event.

Brewpub doors will be open from noon–4 PM, during which time you can check out the array of 750-ml. naturally carbonated bottles available for purchase (prices range from $12–$19).
