MHW-3BOMBER Astra Collection Pressure Tamper

This tamper is available in 51mm and 53.35mm diameters. You should measure the inner diameter of your portafilter basket precisely to ensure a snug fit, as the wrong size will prevent the tamper from sitting flush against the coffee bed.

The ripple base creates concentric grooves in the coffee puck, which helps to break up channeling and encourages more even water distribution during extraction. This can lead to a more balanced shot compared to a completely flat tamper base.

The tamper features a spring-loaded mechanism that clicks once you reach the calibrated 30lb of pressure. This tactile and audible signal removes the guesswork, ensuring you apply the exact same force to every shot.

Yes, the height is adjustable to accommodate different coffee doses and grind depths. This allows you to maintain consistent compression regardless of how much coffee you are using in your basket.

30lbs is the industry standard for consistent espresso extraction, making it an excellent baseline for most home baristas. While some advanced techniques vary pressure, this tamper provides a reliable, repeatable foundation that eliminates human error.
