Decent Espresso's open-source approach and active community have produced a wide range of user-created profiles for the DE1. They cover everything from classic Italian and spring-lever styles to blooming, turbo, and adaptive extractions.
This repository brings many of those profiles together in one place, with author information and documentation where available, making it easier to try different approaches and adapt them to your own coffee.
