For the third year in a row, Trillium Brewing Co. is joining forces with the Rose Kennedy Greenway Conservancy to open the Trillium Garden on The Greenway, and the brewery is celebrating the occasion with a brand new beer.

Central Artery is a 5 percent ABV helles lager brewed with Hallertauer Mittlefruh hops as well as three different types of malt. The new ale is named after the nickname that has been historically used to describe the strip of land where the open-air garden is located.

This is the third time that Trillium and the Rose Kennedy Greenway Conservancy have operated the Trillium Garden, which is meant to “cultivate temporary seasonal spaces in which to enjoy our beer…by welcoming the city-going population and bringing in guest beers from out of town breweries” to the outdoor location.

According to a post on Trillium’s Instagram page, Central Artery Helles Lager is packaged in 16-ounce cans that are available at both of the brewery’s facilities now. The ale will also be served on draft at the Garden on the Greenway when it opens today.
