KNODOS 57mm Espresso Tamper with Walnut Handle, Calibrated Self-Leveling Spring Loaded Tamper for Lelit, Ascaso & La Pavoni Domus Bar

KNODOS Walnut 57mm Espresso Tamper

The KNODOS 57mm Espresso Tamper is a calibrated, self-leveling tamper designed for 57mm portafilter baskets found in select Lelit, Ascaso, and La Pavoni machines. With a stainless steel ripple base, a double spring-loaded mechanism, and a solid walnut wood handle, it brings consistency and control to every tamp.

Sized for 57mm Portafilter Baskets

The 57mm base is designed specifically for machines that use a 57mm basket — a less common but important size found in select Lelit, Ascaso, and La Pavoni Domus Bar models. Unlike using an undersized 54mm or oversized 58mm tamper, this purpose-built size ensures full contact with the coffee bed for even compression.

Calibrated Self-Leveling Design

The auto-leveling base adjusts automatically to sit flat on the coffee bed, correcting minor tilt and ensuring even compression across the entire puck. This reduces channeling and eliminates the guesswork from tamping technique.

Stainless Steel Ripple Base

The ripple pattern machined into the tamping surface grips the top of the coffee puck during compression, reducing the chance of the tamper slipping sideways. The result is a more stable, centered tamp with consistent puck density.

Three Interchangeable Springs

The tamper ships with three springs — 20lb, 25lb, and 30lb — with the 30lb spring pre-installed. Swap springs in seconds without tools to adjust tamping pressure to your preference.

Solid Walnut Wood Handle

The handle is turned from solid walnut wood, chosen for its natural warmth, durability, and comfortable grip. Walnut's rich, dark grain adds a premium feel to your espresso setup while remaining moisture-resistant for daily use.

Frequently Asked Questions

Which espresso machines use a 57mm portafilter?

Select models from Lelit, Ascaso, and La Pavoni use 57mm portafilter baskets. This includes the Lelit Anna, Grace, Anita, Diana, and Glenda, as well as the Ascaso Dream, Arc, Basic, and Steel Uno, and the La Pavoni Domus Bar, Napolitana, Club, and Puccino.

Can I use a 58mm tamper in a 57mm basket?

No. A 58mm tamper will not fit inside a 57mm basket. Using the wrong tamper size prevents proper compression and can damage the basket. Always match the tamper to your basket diameter.

Can I use a 54mm tamper in a 57mm basket?

A 54mm tamper will physically fit but leaves a 3mm gap around the edge, resulting in a large untamped ring. This causes severe side channeling and uneven extraction. A 57mm tamper is required for proper puck preparation.

What is a calibrated espresso tamper?

A calibrated tamper uses a built-in spring mechanism to apply a consistent tamping pressure every time. Instead of relying on feel, the spring compresses to a set force — in this case 20lb, 25lb, or 30lb depending on which spring is installed.

What is a self-leveling tamper and how does it work?

A self-leveling tamper has a base that adjusts to sit flat on the coffee bed regardless of the angle you press. This corrects minor tilt during tamping and ensures even compression across the entire puck.

How do I change the spring on this tamper?

Unscrew the handle from the base assembly, remove the current spring, drop in the replacement, and screw the handle back on. No tools required.
