Harkening Back to Colonial Times: UNH Brews “George Squashington” Butternut Squash Beer

Pale Ale Is Second to Leverage Partnership Between Research and Education

University of New Hampshire brewing science students have taken a trip back in history to brew a new butternut squash pale ale using squash grown as part of the NH Agricultural Experiment Station’s landmark cucurbit breeding program. The brew is reminiscent of the pumpkin ales first developed during colonial times and will be served at the student-led Paul College Hospitality Management Spring Dining Series.

The new brew, George Squashington, is the second to come out of the partnership between researchers with the NH Agricultural Experiment Station and the university’s new brewing science program. The beer was brewed at the UNH Brewing Science Laboratory by students participating in the College of Life Sciences and Agriculture’s advanced brewing class.

Cheryl Parker, manager of the UNH Brewing Science Lab, said the students brewed a hoppy pale ale that uses English and American Ale yeast, butternut squash, and brown sugar. The base malt is Marris Otter barley from England with caramel malted barley for a sweet, nutty color and flavor. Students roasted the butternut squash for the mashing process and added brown sugar as a nod to the colonists who may have added maple syrup or molasses to their brews.

Squash, pumpkins, and some gourds are part of the family of Cucurbitaceae. According to the Oxford Companion to Beer, pumpkin ale was invented in the 18th century by English colonists, who favored its high starch and sugar content.

The butternut squash used to brew the ale was grown as part of the university’s groundbreaking cucurbit breeding program. Brent Loy, experiment station research and faculty emeritus, continues to oversee the research program, which is the longest, continuous cucurbit breeding program in North America. Loy’s research has resulted in more than 80 new varieties of squash, pumpkins, gourds, and melons sold in seed catalogs throughout the world. His research predominantly takes place at the UNH Kingman Research Farm and the UNH MacFarlane Research Greenhouses, both experiment station facilities.

“Pumpkin beers are popular in October, but if you think about the growing season and the fact that it takes several weeks to make a beer and get it on store shelves, beer made with real pumpkins at Halloween is nearly impossible to do using local produce in our area. Many breweries use flavor extracts and pie spices to create a pumpkin-flavored beer,” Parker said.

“There are various ways to use real squash in beer, but historically it was not for flavor, it was for the starch. This is what we did when we added it to our grain and let the enzymes from the barley turn the starch into sugar for our yeast. This will be a perfect end of winter hoppy ale, which we promise will not taste like pumpkin pie,” she said.

George Squashington is the second brew to be developed as part of the partnership between the experiment station and the brewing program. Last fall, the program releases a sour kiwiberry beer Artuga Sour that used kiwiberry varieties grown as part of a ground-breaking kiwiberry breeding research project funded by the experiment station at the UNH Woodman Horticultural Farm.

Parker sees the brew lab’s new partnership with the NH Agricultural Experiment Station enhancing the academic program. Not only will students in the program have access to different local products that are still in development, they also will be able to collaborate and learn about important research at UNH.

According to the national Brewers Association, the New Hampshire craft brewery industry has an economic impact of $353 million in the state, with more than 100,000 barrels of craft beer produced annually. There were 58 craft breweries in New Hampshire as of 2016.

George Squashington is available locally on tap at Hop + Grind in Durham. It also will be served at the Paul College Hospitality Management Spring Dining Series “Around the World in 180 Minutes” April 12-14, 2019. The dining series is organized and run by students in the Paul College Hospitality Management Program.

Founded in 1887, the NH Agricultural Experiment Station at the UNH College of Life Sciences and Agriculture is UNH’s original research center and an elemental component of New Hampshire's land-grant university heritage and mission. We steward federal and state funding, including support from the USDA National Institute of Food and Agriculture, to provide unbiased and objective research concerning diverse aspects of sustainable agriculture and foods, aquaculture, forest management, and related wildlife, natural resources and rural community topics. We maintain the Woodman and Kingman agronomy and horticultural research farms, the Macfarlane Research Greenhouses, the Fairchild Dairy Teaching and Research Center, and the Organic Dairy Research Farm. Additional properties also provide forage, forests and woodlands in direct support to research, teaching, and outreach.
