Graduated tamping for consistent extraction Tamp depth is adjustable up to 13 mm by rotating the middle ring. This provides uniform tamping pressure across shots, helping achieve stable espresso extraction and improved flavor and quality. Intuitive tactile feedback with a spring mechanism The spring mechanism does not dictate pressure. It lets you feel the resistance of the coffee bed, giving a more intuitive tamping experience and removing guesswork about when to stop. Key attributes Function: adjustable tamp depth for uniform compression and repeatable results Mechanism: tactile spring feedback that supports consistent technique without fixed pressure Performance: supports consistent espresso extraction and quality across shots Use scenarios Home espresso routine: dial in a repeatable tamping depth to produce consistent shots from the same machine Experimenting with beans or grind sizes: use the tactile feedback and depth adjustment to maintain stable pressure as bean characteristics vary Shared equipment in a household or small cafe: multiple users can achieve similar tamping feel and results by using the same depth setting and feedback Notes Designed to enhance control over tamping without changing other steps in the espresso process No additional tools required; adjust the middle ring to set the desired tamp depth and use the spring feedback to know when to stop
