A recent research initiative led by Langara College and the University of British Columbia is delving into the art of brewing beer by harnessing wild yeast sourced from various regions in British Columbia. This study proposes a potential solution to support the struggling brewing sector in B.C. while introducing novel beer flavors. Funded by Genome B.C., the project involved researchers and students collecting wild yeast samples from locations across B.C. and the Pacific Northwest, including Prince George.
Dr. Stephanie Cheung, the project lead and an instructor at Langara College, highlighted the limited availability of commercial yeast strains for brewing. She emphasized the challenges faced by brewers due to the water-intensive nature of hop cultivation, exacerbated by recent drought conditions. Importing hops from the U.S. incurs additional expenses for brewers, further straining the industry.
Cheung explained the multifaceted role of yeast in beer production, stressing its significance beyond alcohol fermentation. The project originated from a colleague’s suggestion to explore yeast samples collected by students during a botany class, leading to innovative discussions on beer production methods. By experimenting with wild yeast strains, the researchers aimed to reduce the reliance on hops for flavor profiles, showcasing the versatility of yeast in brewing.
By collaborating with local breweries such as Parallel 49 and Barnside Brewing in the Lower Mainland, the research team garnered support for their endeavor, with both breweries endorsing their grant funding applications. Barnside Brewing, known for growing its hops and grains, has also ventured into capturing wild yeast strains. Co-founder Ken Malenstyn emphasized the value of utilizing locally sourced ingredients for a distinctive taste experience, akin to the concept of terroir in wine.
Looking ahead, Cheung and her team aspire to establish a wild yeast discovery and characterization platform tailored for breweries in the province, with a prototype anticipated to be unveiled this year. The ultimate goal is to facilitate a more cost-effective brewing process, potentially revolutionizing the beer industry in British Columbia.
