Puck Spring

This spring is an experimental piece used to modify the behaviour shot during an espresso shot. It could possibly reduce expansion of the puck, compresses the puck further during the shot while the puck degrades, or just simply prevents the puck screen or mesh screen from lifting due to water flow. Generally, it slows down the flow, leading to longer shot times when all other variables are the same.

This is meant to fit inside a basket with a minimum diameter of 49mm, and fits between the shower screen of your espresso machine and the puck screen or mesh screen on top of your puck. It's made of 304 stainless steel.

Requirements

• Espresso machine with a shower screen
• Puck screen or mesh screen above the espresso puck (spring should not directly sit on tamped coffee)
