Aesir Filters was born out of a relentless pursuit for better coffee. The founder, Eldric Stuart, was operating Aubade Coffee at the time, a world-renowned* shop known for its attention to detail and focus on quality, and he was never satisfied with any coffee he ever brewed. Always looking to better understand the science of brewing, he kept experimenting, trying to eliminate negative cup aspects. Knowing that one of the biggest differences between some brew methods is the type of paper filter used, Eldric started exploring different filtration mediums for the Aeropress while prepping for the Canadian Aeropress Championship in 2016.
Like many others, he tried using filters available from various brew methods, and while they produced different results, they still weren’t quite what he was seeking. He began working with paper suppliers, testing samples, and searching for the specific qualities that would produce the best possible cup. He eventually identified the ideal pore size and flow rate for the Aeropress and began using the filters in competition, placing 4th, 3rd, and 2nd in subsequent years while preparing to share the product more widely.
Today, multiple former WAC winners use Aesir filters regularly, including Carolina Ibarra Garay and Shuichi Sasaki (who also serves as our official Japanese distributor). In last year’s competition, many National Champions—Japan, Denmark, France, the Netherlands, and the UK among them—relied on our filters. We were especially excited to see both the 1st-place and 3rd-place finishers at the 2019 WAC competing with Aesir. The filters have become a standard choice in competitions and at home for anyone serious about brewing great coffee.
Aesir Filters has since joined KaffeBox, with operations now based in Sarpsborg, Norway. Production and global distribution continue from the KaffeBox headquarters, ensuring stability, ongoing availability, and room for further development. We continue to innovate and refine new products as part of our long-running effort to push the boundaries of brewing.
