Crafted with a solid stainless steel base and a comfortable Bakelite handle, this tamper ensures a consistent coffee puck. Its unique convex curve slightly thins the center, effectively preventing water channeling around the edges for a more even extraction. This durable and stylish accessory guarantees uniform compression of grounds, leading to consistently better espresso shots. It is highly recommended for use with ECM machines like the Mechanika VI Slim Heritage Line and the Synchronika II.

Know before you buy
A convex base is designed to slightly thin the center of the coffee puck, which helps direct water toward the edges. This helps prevent channeling, where water finds the path of least resistance, leading to a more uniform and balanced extraction.
This tamper features a 58.4mm base, which is specifically engineered for precision-fit baskets found in ECM machines like the Mechanika VI Slim and Synchronika II. It is best suited for machines that utilize a standard 58mm commercial-style group head.
At 400g, this tamper provides a substantial, balanced feel that helps you apply consistent pressure with less physical effort. The added weight allows gravity to assist in achieving a level, compressed puck.
Yes, Bakelite is a high-density, heat-resistant material known for its durability and comfortable grip. It is an excellent choice for a tool used multiple times a day, as it remains sturdy and easy to clean over time.
While the tamper itself doesn't change your grind requirements, the improved extraction consistency may reveal that your current grind is either slightly too coarse or too fine. You may need to make minor adjustments to your grinder settings to dial in the perfect shot with the new puck density.
