Tap & Mallet, a pioneering beer bar and gastropub in Rochester’s South Wedge, announced Monday it will close at the end of December after 14 years of business. The move comes amid a local beer scene changed by market forces and the coronavirus pandemic. Joe McBane, a native of Sheffield, England, who came to Rochester more than 20 years ago to work at the Old Toad on Alexander Street, co-founded Tap & Mallet with Casey Walpert. The two also own The Sheffield, which opened late last year near Brighton’s Twelve Corners. It will remain open, they said.
