Under första lördagen av SBWF2022 så träffade jag Lotte Peplow som är europeisk ambassadör för Brewers Association, en amerikanska organisationen för Craftbrewers. Bland annat kom frågan om hur mycket de satsas på hållbar ölproduktion, och hur funkar egentligen pantsystemet för alla ölburkar i USA .
Hon frågade via mail om jag var intresserad att publicera en gästartikel - skriven av henne - i ämnet, och självklart tackade och bockade jag.

Lotte Peplow, the Brewers
Association’s American Craft Beer Ambassador for Europe, looks at latest sustainability
initiatives in the American craft brewing industry
The American craft beer
industry emits about half a billion metric tons of carbon dioxide into the
atmosphere annually and is all too aware of the need to conserve energy and
become more sustainable and environmentally responsible. Brewing is an energy intensive business that
creates waste materials and by-products in equal measure and in today’s
environmentally conscious landscape the need for sustainability is more
important than ever. The majority of
American craft breweries are acutely aware of their impact on the environment
and strive to develop new and creative ways to become more sustainable, more
energy efficient and more environmentally responsible. Here’s an overview of the latest initiatives
being undertaken on the other side of the Atlantic.

Sierra Nevada Brewing Co is the
third largest small and independent American craft brewer in the States and
prides itself on its approach to sustainability, regularly passing up the
chance to brew more easily and cheaply.
At the main site in Chico, CA,
there are 3.5 football fields worth of solar panels which work in tandem with
two megawatts of Capstone microturbines to provide over 90% of the electricity
needed to run the brewery. Waste heat is
captured and used to make steam and hot water for the brewing process.
Instead of venting naturally
produced CO2 from fermentation, Sierra Nevada recovers it, cleans it and sends
it back into the brewery to pressure tanks and assist in packaging. Recovered CO2 contains less oxygen than
commercial CO2 improving the quality of the beer.
Water conservation is crucial in
drought-stricken California and Sierra Nevada has eliminated water-based
lubricants on the bottling and kegging lines which not only reduces water
consumption but wastewater heading to the on-site treatment plant. The brewery recovers water used to rinse
bottles prior to filling and uses it in vacuum pumps that dispense beer into
bottles, saving about 2.5million gallons of water annually. This environmental stewardship is at the
forefront of Sierra’ Nevada’s core values and as important as making great
beer.
Mandi McKay, director of sustainability
and social responsibility at Sierra Nevada Brewing Co, comments: “We have
excelled at the philosophy of closed loop sustainability and it’s proven to be
a wonderful operating strategy. We’ve shown that waste coming out of one
process such as heat, water or CO2 recovery can become a resource for something
else. We’re very energy intensive in
the brewing industry, we make a lot of heat and we use a lot of heat so we’ve
gone all in on recovering heat and steam and that closed loop philosophy has
been a guiding principle for us. At
Sierra Nevada we do a lot more than just brew amazing beer and the same
commitment to continuous improvement and zero waste runs across the board. We’ve always been
interested in connecting ourselves with our supply chain - early on we planted
our own hop field - and that comes from the fundamental belief that everything
is connected and our impact on the environment is impacting ourselves.
Firestone Walker
Brewing Co
Based in California,
Firestone Walker build their sustainability strategy on three main tenets:
solar energy, eliminating waste and conserving water. The site is home to an impressive 9.5
acre solar array which moves with the sun and generates the majority of energy
needed by the brewery. It offsets about
3,000 metric tonnes of carbon emissions annually or the same carbon footprint
as a 4,000 acre forest.
Matt Brynildson, brewmaster at Firestone
Walker says: “Everything involved in the brewing process – hops, malted grains
– comes from farms and you learn through that process the importance of
sustainable business practice. When
farmers practice more sustainably, the hops get better and it makes better
business sense.
“We’ve always collected spent grains and
sent them off to farmers as feed but as we’ve grown we’ve improved our processes
by separating our yeast streams from our spent grain streams, allowing us to
send those streams to different farms for different purposes. We feed more than 20 million pounds of spent
grains annually to local livestock and 90% of brewing grains are delivered in
bulk to eliminate packaging waste
“Water is a precious resource in California
and it takes 5-7 gallons of water to make one gallon of beer. The beer goes out to the community and the
rest of that water is processed in our waste water plant and effluent system
allowing us to regain some energy from it. Ultimately, we’re discharging water
that’s in better shape than before. We
treat 35 million gallons of process water annually on site and return it to the
local aquifer.
“The more we brew and the more raw
materials we use the great the responsibility we have to use those materials
wisely and it’s not just about the bottom line, it’s about doing the right
thing,” he adds.
But
does the beer drinker care if their beer is made responsibly or not? Some may claim that general awareness and
demand isn’t high enough yet but this could change. A study from Indiana University, Iowa in
2018, albeit of a limited sample size, found that the ‘majority of beer
consumers are willing to pay more for sustainable beer’. People who already purchase premium beer and
who chose other environmentally friendly goods and services are most likely to
pay extra for sustainably produced beer.
Whether this translates into a full-scale change across the brewing
landscape remains to be seen but it is a small step in the right direction.

Fremont Brewing Co
Fremont in Seattle, Washington is making
a name for itself as a sustainable brewery by using a ‘Salmon Safe’
certification on one of its beers, Cowiche Canyon Fresh Hop Ale. Founder Matt Lincecum, explains: “The Cowiche Farm is a
joint project between Fremont and farmers from the Yakima Chief Hops team. We
started this collaboration 12 years ago to develop organic hop varieties,
methodologies of growing/harvesting and to show the craft beer world that
organic hops are some of the very best hops. Several years ago, we were
certified Salmon Safe and are extremely proud of this accomplishment for the
Cowiche farm. We believe that including the logo on the
packaging has boosted the brewery’s visibility and perhaps sales.”
Sustainability is a huge part of the
brewing process: Water isn’t heated with natural gas, but with steam which
captures heat from the brew kettles during production and redirects it to the
hot water tank. Excess liquid is
filtered into drainage, while the grains are captured and donated to feed local
cows.
Fremont is also serious about social
and economic sustainability as well as environmental. They provide employees with benefits such as
subsidised healthcare and transit cars, paid family leave and they give back to
the community that supports them because “it’s the right thing to do.”
Sustainability is a core value for
the vast majority of American craft brewers, the pursuit of quality is another
borne out by the number of medals and top honours American craft beer wins at
prestigious international beer competitions that are judged by the finest, most
experienced palates in the world. One of
the key reasons behind the success of American craft beer internationally is
the proximity to the freshest examples of highly-sought after hop
varieties. By visiting the hop fields
themselves American craft brewers are able to develop flavour profiles in beer
that are difficult to control elsewhere.
Combine quality and freshness of raw materials with American craft
brewers’ technical expertise and it’s easy to see why American craft beer is
renowned for its quality the world over.
The Brewers Association, the
not-for-profit trade association representing small and independent American
craft breweries, is heavily invested in making a wide range of sustainability
resources available to the brewing industry including the Brewers
Association Sustainability Best Practices Manual and a Sustainability
Benchmarking Tool. It conducted its first sustainability benchmarking study in 2014, which measured energy and water use, and
addressed ways that breweries could reduce water and solid waste, as well as
carbon dioxide. It was an immediate success. By following the study’s
sustainability targets, the first group of participating breweries cut enough
costs and waste to save anywhere from $35,000 to $235,000 annually. Other manuals are available from
the Brewers Association including energy, solid waste, sustainable build and
design strategies and wastewater management.
