Hill Farmstead Brewery has collaborated with a unique group of people for its latest Leaves of Grass release.

Leaves of Grass: 7/31/2017 is a “farmstead ale” brewed with malted barley, raw and malted wheat and foraged wood sorrel before being “fermented and aged in French oak and then further aged atop fresh Vermont blueberries.” The new beer was created in collaboration with students from Sterling College located in Craftsbury Common, Vt. and was brewed on July 31, 2017.

As the first part of the beer name indicates, Leaves of Grass: 7/31/2017 is part of Hill Farmstead’s Leaves of Grass Series, which sees the brewery use “uniquely different processes and ingredients, all of which further our understanding of the art and science of brewing” for each release. The series debuted in October 2015 with Leaves of Grass: July 5, 2015, a 4.5 percent ABV “farmstead ale” brewed with green tea, citrus and “apple water” that was fermented in oak.

According to a post on Hill Farmstead’s website, Leaves of Grass: 7/31/2017 will be packaged in 375ml bottles ($16) and will have a two bottle per person purchase limit when it is released on April 25.
