The Brooklyn Brewery just introduced a new beer to its ever-changing array of offerings: Mary's Maple Porter, a tasty and potent (7.5% alcohol by volume) dark ale made with real maple syrup from upstate New York. The beer is named for the brewery's "quality control" supervisor Mary Wiles, who owns 500 acres of maple trees on property in Onondaga. 50 gallons of her Cedarvale Maple Syrup go into each batch, and while the beer doesn't taste sweet, you can definitely taste maple, as well as caramel, chocolate, and coffee flavors from the brewery's blend of roasted malts. Here's a video starring Brooklyn Brewery's brewmaster Garrett Oliver, who has some background for the beer nerds:

The Maple Porter, which is not as heavy as most other porters, will be available now through April in draft only. Here's the list of bars and merchants where it's currently offered, and you can also find it at the Brooklyn Brewery, which welcomes visitors daily and is hosting the "Smorgasbrewery" every Sunday this the winter, until Smorgasburg returns to its outdoor location in the spring.
