The Weiss distribution technique was developed by John Weiss in 2006 to address clumping issues in coffee grinders.
The technique involves using medically precise needles to declump and homogenize the coffee grounds.
Early methods of distribution, such as stock fluff and north-south-east-west, were not sufficient for even extraction.
Over time, the technique evolved with the use of acupuncture needles for precise and efficient distribution.
The Weiss distribution technique improves extraction efficiency and consistency, resulting in better-tasting espresso.
