MHW 3Bomber Flash Tamper Set

Tamping compacts the coffee powder in the sieve to obtain a firm and uniform coffee cake with a smooth and even surface. Correct tamping avoids the channelling effect and ensures that all the coffee powder is extracted evenly, releasing all the flavorings from the coffee.

This is a pressure-controlled tamper with a preset pressure of approximately 14 kg. When the preset pressure is reached, a mechanical signal sounds as feedback, and the tamper releases the pressure again. After several tests, MHW 3Bomber has found that at a constant pressure of approximately 14 kg, the extraction rate is almost the same for different amounts of powder and different extraction times. The outer ring, which lies flat on the portafilter, ensures that the tamper is always pressed down vertically. The tamper is simply placed on top and pressed down, with the spring pulling the base back up again.

This tamper fits perfectly on 58 mm portafilters. Through repeated testing, MHW 3Bomber has determined that 58.35 mm is the perfect size for leveling tools and tampers. These fit exactly into 58 mm portafilters and reduce wastage of coffee powder.

It is a set with four different bases (concentric groove, flat base, convex base, and honeycomb base) that can be interchanged. A replacement spring and a small tamper holder are also included. The tamper has an ergonomic handle and sits comfortably in the hand.

The entire tamper is made from high-quality materials. The handle is made of solid walnut wood, the middle section is made of an aluminum alloy, and the base and spring are made of stainless steel (SUS304). The entire tamper can be dismantled and is therefore easy to clean.

With this tamper, perfect coffee extraction can be achieved when used correctly.
