MHW 3BOMBER Impact Tamper, Astra Series (T7016-OS)

The Astra series from MHW 3Bomber uses solid metal materials as a base, combined with a dark color scheme. The improved galvanic technology allows for the unique black color "Obsidian".

By tamping, the coffee grounds in the portafilter are compacted to create a firm and even coffee puck with a smooth and level surface. Proper tamping avoids channeling and achieves a uniform extraction of the entire coffee grounds, thereby dissolving all the aromatic substances from the coffee.

The Astra Impact Tamper is a pressure-regulated tamper with a preset pressure of 13.6 kg. When the preset pressure is reached, a mechanical signal sounds as feedback, and the tamper releases the pressure. After several attempts, MHW 3Bomber found that at a constant pressure of 13.6 kg, the extraction rate is nearly the same with different amounts of grounds and varying extraction times. The outer ring, which rests flat on the portafilter, ensures that the tamper is always pressed straight down. The tamper is simply placed on top and pressed down, with the spring pulling the base back up.

This tamper fits perfectly on 51 mm portafilters.

The tamper features an ergonomic handle and feels good in the hand. Additionally, the base is equipped with concentric grooves, allowing more coffee grounds to come into contact with the water, leading to better extraction.

The entire tamper is made from high-quality materials. The handle and the middle part are made from an aluminum alloy, while the base and the spring are made from stainless steel (SUS304). A replacement spring is included.
The entire tamper is disassemblable, making it easy to clean.

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