Ingenuity Saves Money: Geothermal Heat Exchanger

Brewing beer is a water and energy intensive process; wastewater treatment and disposal can be challenging. Blasty Bough in Epsom has a culture of sustainability and began collaborating with the New Hampshire Pollution Prevention Program prior to beginning to brew. In an effort to reduce waste and chemical use, as well as save money, Blasty Bough developed an innovative heat exchanger to chill the wort (hot beer) without using glycol and large quantities of cooling water. Drawing from past experience using geothermal cooling in an industrial process, the owner applied this approach to maximize efficiency and sustainability in the brewery.
