The Wachusett Brewing Company has been operating since 1994 in Westminster, Massachusetts.
This beer pours a dark amber, orange in color, slightly cloudy. There is an inch of off-white thick, creamy and foamy head. The aroma is floral, herbal, grassy and crusty bread. The taste is richly fruity, creamy tropical fruits and melons, along with floral, more so than citrusy. All of the fruit is on a discernible, but not overbearing crusty bread maltiness. This is really delicious. The beer is 6.0% ABV and 55 IBU's. It is made with Cascade, Amarillo and Centennial hops.
As the beer is from Massachusetts, I am guessing the name comes from the big green outfield wall at Fenway Park, home of the Boston Red Sox.
