Overview
This workshop showcases the exact philosophy used to win the World AeroPress Championship and over 10 national titles, and to coach 300+ national champions worldwide.

Together, we brew competition coffees and improve them only by changing water composition.
Participants experience first-hand how water can transform a cup without changing grind size, brewer, or recipe.

A powerful session for competitors and professionals interested in performance-driven brewing.
