MHW 3BOMBER Flash Tamper - 58.5mm

With tamping, the coffee grounds in the filter are compacted to create a solid and even coffee puck with a smooth and level surface.
Proper tamping prevents channeling and achieves an even extraction of all the coffee grounds. This ensures that all the flavor compounds from the coffee are extracted.

This is a pressure-regulated tamper with a preset pressure of about 14 kg. When the preset pressure is reached, a mechanical signal sounds as feedback, and the tamper releases the pressure. After several tests, MHW 3Bomber found that at a constant pressure of about 14 kg, the extraction rate is nearly the same for different amounts of coffee grounds and different extraction times. The outer ring, which sits 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 58 mm portafilters.
Through repeated tests, MHW 3Bomber determined that 58.35 mm is the perfect size for leveling tools and tampers. These fit precisely into 58 mm portafilters and reduce coffee ground waste.

The tamper has 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 is made of solid walnut wood, the middle part consists of an aluminum alloy, and the base and spring are made of stainless steel (SUS304).
The entire tamper is disassemblable, making it easy to clean.

With this tamper, perfect coffee extraction can be achieved with proper use.
