The FSTC attended the 2016 California Craft Beer Summit, a three-day event with an interactive expo, multiple educational sessions, and a concluding beer festival in Sacramento, CA this past September. The annual event is hosted by the California Craft Brewers Association (CCBA), an entity dedicated to connecting and empowering California craft brewers through advocacy, education, and communication. The Summit brings together craft brewers, visionaries, innovators, business partners, distributors, retailers, and beer lovers across the state to showcase and highlight the craft brewing industry’s growth and success.
Beer brewing is a water and energy intensive process. It takes about 20 gallons of water to produce one pint of beer. Most of that water is used in growing barley and hops, however, a significant amount is used in the brewing process itself. In addition, an essential part of brewing is heating and cooling liquids as rapidly as possible, which requires a lot of energy. Most breweries also operate taprooms and restaurants, which have their own energy and water demands (and where the FSTC could really assert its years of foodservice expertise!) Armed with these notions, the FSTC sought to learn more about the craft beer industry’s practices, while also educating the industry on water- and energy-efficiency at this year’s Summit.
Co-hosting the Water Innovations Showcase booth with the nonprofit group American Rivers, the FSTC created various displays showing how brewers and facility operators could save water (and energy) in their breweries.
Making It Cold: Savings are Brewing. This hands-on brewing demo featured a copper coil immersion chiller, a (simulated) bucket of wort (aka not-yet-fermented beer), and three buckets of cooling water. The goal was to visually demonstrate the substantial volume of water required to quickly cool down hot wort before fermentation in the brewing process. Seeking a better grasp on the attending breweries’ operations, we asked, “How much water does it take to cool your wort?” Attendees had widely different answers depending on the size of their chillers. We followed with, “What do you do with your leftover cooling water?”
We found that most larger breweries already have sustainable mechanisms in place for water conservation that include reusing cooling water for cleaning brewing equipment, bottling lines, kegs, etc., or even using a glycol cooling system in place of water altogether. However, we learned that some smaller breweries and homebrewers still dump their used cooling water down the drain. With an ongoing statewide drought and the ever increasing price of water, we encouraged these brewers to find reuses for all that wastewater.
What’s Brewing in Your Business? The FSTC also displayed a “Think Tank Questionnaire” where we surveyed some of the attendees about the specifics of their brewery, their foodservice operation (if applicable), their heating/cooling system, etc. This provided a better understanding of California brewery demographics and how the FSTC can assist the brewing industry in its efficiency and sustainability efforts in the future.
Alongside the interactive sections of the booth, we also had four stations equipped with different energy and water saving tips that most any brewer or brewery could utilize.
Refrigeration Savings are Brewing. Many breweries use custom walk-in coolers for fermentation and keg storage. As such, we recreated the FSTC’s “4-on-the-door” mnemonic to help brewers limit energy waste in walk-ins. “4-on-the-door” is 1) Install an auto door closer, 2) Check door hinge alignment, 3) Inspect and maintain door gaskets regularly, and 4) Add strip curtains as a secondary barrier to heat infiltration.
Water Savings are Brewing. For the brewery restaurant or taproom operator, the easiest and most inexpensive measure you can take to conserve water is to switch to a low-flow pre-rinse spray nozzle. By changing out that old high-flow nozzle to a 1.15 gpm or less nozzle, you can save approximately $1,800/year! Check out California rebate-qualified PRSVs here.
Dish Machine Savings are Brewing. By purchasing an ENERGY STAR® dishwashing machine, breweries can cut costs in half! A standard dishmachine costs $1,200/year to operate, whereas an ENERGY STAR® dishmachine costs $600/year to operate. For more tips on dishmachines, please visit fishnick.com
Energy Savings are Brewing. Efficient lighting can save you big money. With the power required to light one Edison bulb, you could light fifteen similar LED bulbs! A 60 watt Edison bulb’s annual cost to operate is $45/year, while a 4 watt LED Edison bulb’s annual cost to operate $3/year. What large savings for something so simple to change!
The craft brewing industry was built on innovation, collaboration, and a shared sense of environmental responsibility. With that in mind, the FSTC was heartened to learn that the industry has taken great strides in sustainability and energy efficiency with many of the largest craft brewers leading the way. At the same time, much more can be done to engender energy and water saving best practices industry-wide, not only in the back brewhouse, but in the restaurant and taproom too. The Craft Beer Summit gave the FSTC valuable insight into the scale and particulars of this exciting industry, while also working to expand the FSTC’s energy- and water-saving influence.
