The World AeroPress Championship brings together the planet’s most fun-loving baristas. CEO Tim Williams shares the story behind the phenomenon

Last year, the World AeroPress Championship (W.A.C.) season brought together more than 3,000 competitors at 120 events in over 60 countries.

But the idea started with much humbler beginnings—three coffee geeks and a cake in a small room in Norway.

In the years that followed that first competition, fans all around the world asked to lead their own events, and the format began to spread. We interview the CEO, Tim Williams to learn more about what makes the competition special and what structure he and his team offer organizers from HQ.
