Barrel House Z

95 Woodrock Rd, Weymouth, MA 02189 

Barrel House Z’s development of a revolutionary new technology called Zenso1, uses a proprietary yeast and enzyme combination that enables spent grains to be reused, producing a second beverage of hard seltzer or canned ready-to-drink cocktails. This revolutionary process reduces Scope 3 emissions (those associated with supply chain) by eliminating the need for deliveries of malt/grain.  

Barrel House Z converted their production use of CO2 to nitrogen for purging tanks and kegs, which further decreases their costs and Scope 1 (on-site) emissions. Through water conservation practices, they achieved a lower-than-industry average 5 to 1 water-to-beer ratio. 

 Local distribution concentrated on the South Shore decreases their Scope 2 emissions compared to breweries that distribute to a larger footprint.

Bent Water Brewing Company

180 Commercial St, Lynn, MA 01905 

Bent Water Brewing Company, true to its name, is notable for its water conservation and wastewater mitigation efforts. It saves and reuses water via a closed-loop heat exchanger system, a circulating water sink for cleaning parts, and pitched floors with a pointed drain system that requires less floor cleaning. Every drain is connected to one single sump pump so that a gravity waterfall effect filters out all solids during fermentation. This allows the brewers to side stream most organic material to keep it out of the sewer and decrease the strength of wastewater. Bent Water even participated in a collaboration with True North Ales on a beer called “Endangered Ale,” which raised awareness and funds to benefit the endangered Ipswich River.

Brick and Feather Brewery

78 11th St, Turners Falls, MA 01376 

Brick and Feather Brewery’s sustainability efforts to decrease solid waste are exemplary, reducing or eliminating plastic wherever possible. All beer sold on-premises excludes plastic packaging. Cardboard boxes are offered for transporting when necessary. Selling both refillable growlers to-go and beer in refillable kegs reduces packaging further. They also offer a can carrier take-back and reuse program. On-premises beer is always served in reusable glassware, whether in the taproom or on the patio. 

Their taproom draught system is a highly efficient direct-draw with flow control valves, which decreases wasted beer by preventing excessive foam. 

Brick and Feather Brewery’s participation in an energy audit through Center for Eco Technology (CET) ² , prompted the installation of efficient LED lighting throughout the facility.

Cambridge Brewing Company

1 Kendall Square, Cambridge, MA 02139 

Cambridge Brewing Company has been thinking about sustainability for longer than most breweries have been in business. Located in a bustling business district, the brewpub is steps from public transportation, bikes lanes, and a nearby public bike share station.  

CBC has sourced 100% renewable wind energy from Constellation Energy for more than a decade. More recently, they contracted with a community solar farm, which lowered their energy footprint even further. The taproom and restaurant are heated and cooled by a highly efficient heat pump, and most of the lighting is LED.  

CBC also excels in solid waste prevention, sorting trash, recycling, and organic waste such as food scraps (which go to an anaerobic digester) in the back of the house. All beer is served in proper reusable glassware.

Castle Island Brewing

31 Astor Ave, Norwood, MA 02062 

Castle Island Brewing utilized the Brewers Association Benchmarking tool, with help from UMass Boston grad students, to compare water, energy, and purchased CO2 efficiency. The results reflect a low 7 to 1 water to beer ratio resulting from multiple conservation efforts.  

They conserve both water and energy using a hot liquor tank and cold liquor tank. Additional low-cost efforts include floor cleaning primarily with squeegees and high-pressure adjustable hose nozzles, and a switch to more efficient cleaning chemicals that use less water. 

Castle Island’s Fiver beer series is an annual fundraiser for local charitable causes, including environmental nonprofits like the National Marine Life Center and the Cape Cod Museum of Natural History.

Element Brewing & Distilling

16 Bridge St, Millers Falls, MA 01349 

Element Brewing & Distilling are highly efficient at reducing energy use and recycling. Sourcing 100% renewable energy through community solar eliminates their Scope 2 (purchased electricity) greenhouse gas emissions. Further emissions are prevented by sealing fermentation tanks as fermentation winds down, allowing for a buildup of natural carbonation. This decreases Scope 1 GHG emissions and reduces the amount of purchased CO2. Its high-efficiency HVAC system and programmable thermostat conserve energy. The brewery also captures heat exchange water and transfers it into an empty lager tank, recycling it for use in other operations, even landscape watering.  Grain bags and can carriers are reused whenever possible, and trash generation has been reduced to just one 50-gallon receptacle per week.

Exhibit 'A' Brewing Company

81 Morton St, Framingham, MA 01702 

Exhibit ‘A’ Brewing Company’s goal from the start was to reduce energy, resources, and emissions in brewing beer. Their conversion to 100% renewable energy community solar has eliminated Scope 2 (purchased electricity) emissions. A founding member of the Northeast Grainshed Alliance ³ , it initially doubled the amount of local grain used in 2022 and has been increasing further ever since. Exhibit ‘A’ also participates in the SQFT Project ⁴ , which measures and promotes the amount of farmland supported by sourcing local malt/grain and reduces its Scope 3 (supply chain) emissions.

The Brewery at Four Star Farms

508 Pine Meadow Rd, Northfield, MA 01360 

The taproom at The Brewery at Four Star Farms is one of the few places in the U.S. where you can drink a beer while enjoying a view of the agricultural ingredients used to brew it. Surrounded by 17 acres of hop yards, as well as fields dedicated to home-grown grain, it's literally the definition of drinking local. Even the water is local, sourced from wells on its own property for brewing and any residual liquids applied as a nutrient for the hop farm. You’d be hard pressed to find a brewery with lower Scope 3 (supply chain) greenhouse gas emissions. 

The brewery and taproom were constructed with efficiency in mind. Radiant floor heat, LED and motion sensor lighting, and an innovative steam-jacketed brewing system minimize energy use while maintaining an aesthetically appealing environment.
