Alaskan Amber bottle and original Chinook Alaskan Amber bottle
Alaskan Brewing Company will always be one of my favorite breweries if for no other reason than I lived in Juneau, AK for awhile as I was being introduced to craft beer. At that time, the brewery was called Chinook Brewing Company. Chinook (now Alaskan) Amber (5.3% ABV, IBUs 18) was the beer of choice in town and today remains their flagship beer.
Since then I have enjoyed many of their award winning beers such as their Smoked Porter (6.5% ABV, IBUs 45), Barleywine (10.7% ABV, IBUs 50), and Baltic Porter (9.8% ABV, IBUs 53)
When I lived in Juneau, the people there were rugged and innovative, and this new project that Alaskan Brewing Company has created is a great example of this.
Juneau, Alaska (January 15, 2013)—The Alaskan Brewing Company is now operating with a new fuel source: beer. More specifically, they are using the wet grain known as “spent grain,” left over from the brewing process, as the sole fuel source for their new steam boiler. Alaskan is the first craft brewery in the world to use this brewing by-product in this way, reducing the company’s fuel oil consumption in brewhouse operations by 60-70 percent.
“We have the unique honor of brewing craft beer in this stunning and remote place,” explains Alaskan Brewing Co-founder Geoff Larson. “But in order to grow as a small business here in Alaska and continue having a positive effect on our community, we have to take special efforts to look beyond the traditional to more innovative ways of brewing. Reducing our energy use makes good business sense, and good sense for this beautiful place where we live and play.”
The brewery began the spent grain energy process in 1995 with the installation of a grain dryer. The equipment dried the wet, protein-rich spent grain in preparation for shipment to the lower 48 for use as cattle feed, due to the absence of farms or ranches in Southeast Alaska. Alaskan designed the grain dryer to use up to 50 percent of the grain as a supplemental fuel source to heat the dryer itself. This reduced the oil required in the drying process, and provided experience in burning spent grain that would later prove useful in designing the steam boiler.
In 2008, Alaskan became the first craft brewery in the nation to install an energy saving piece of brewing equipment called a mash filter press. The mash filter press, in addition to providing greater energy, water, and materials efficiencies, produces a lower-moisture-content spent grain than does the more traditional lautering process. This form of spent grain better lends itself to drying and for use as fuel for the brewery’s grain dryer and, ultimately, the new spent grain steam boiler system.
Over the latter months of 2012, Alaskan completed the final stage of the process with the installation and commissioning of the $1.8 million, custom-constructed spent grain steam boiler. This brewing byproduct is a unique and challenging fuel, so brewery engineers put their years of experience with drying grain to work with existing combustion technology to develop and fine-tune this first-of-its-kind process.
Alaskan expects that the new boiler will eliminate the brewery’s use of fuel oil in the grain drying process and displace more than half of the fuel needed to create process steam in the brewhouse. This translates to an estimated reduction in fuel oil use in brewhouse operations by more than half. With moderate growth assumptions, Alaskan expects to save nearly 1.5 million gallons of oil over the next ten years.
In 2011, Alaskan Brewing Company celebrated 15 years with the release of their Perserverance Ale. Alaskan Brewing distributes to Minnesota and Wisconsin, which is as close as it currently gets to Michiana. Luckily I have a very kind sister-in-law who lives in the Twin Cities.
