What is a Portafilter?
A portafilter is the crucial component that holds your ground coffee during the espresso extraction process. It consists of a handle, basket, and spouts, working together to create the perfect shot of espresso. At SIF Coffee Tools, we emphasize the importance of understanding your portafilter as it's the foundation of excellent espresso.
Why Proper Portafilter Selection Matters
