Our KM Tamper

We tamper a lot. From now on with our own tamper. We present our own tamper, developed according to the specifications of our barista team for precise tamping and consistent extractions. Manufactured by Moritz and Tobi in the Ruhr area - 100% Made in Germany .

Product features: Our tamper

• Diameter: 58.5mm. At 58.5mm, the tamper fits perfectly with all precision sieves and conventional 58mm sieves from espresso machines. 58.5mm is our preferred tamper size. Thanks to the flush finish, the tamper seals right up to the edge and minimizes the risk of channeling.

• Material: The base (lower part) is made of stainless steel (1.4301), ideal for the food industry (e.g. beverage containers, cutlery).
  

• Innovative design: A convex recess in the base prevents vacuum formation, which means the coffee puck does not loosen or get damaged when removed. In addition, the upper surface is flush with the sieve, which supports straight tamping.
  

• Individuality : Each wooden handle is unique; small deviations are possible. Hairline cracks in the wood are professionally sealed and do not represent a defect.
  

• Surface treatment: The wooden handle is treated with a food-safe oil-wax combination (EURO standard 1186 part 5/14) for water repellency and suitable for use in the kitchen (please note care instructions).

• Scope of delivery: tamper handle & tamper base.

The manufacturing process - local and as resource-efficient as possible

Tampers are a typical imported product and are mainly manufactured in the Far East. This is absurd in many ways. Many craft businesses in our region have experience with high-quality and, above all, precise metal and wood processing. Nevertheless, individual components are transported around the globe instead of strengthening local networks.

Our tamper is produced locally and in a resource-saving manner The handle is manufactured in Lüdinghausen, the metal base in Hünxe, just 4 km from our coffee maker. This way we strengthen local networks and avoid long transport routes.

manufacturing process:

• Base: Manufactured in the workshop of Tobi Zimmer in the family business Zimmer Maschinenbau on modern CNC lathes.
• Handle: Made in Elke Brandt's workshop instead of being manufactured in a multi-step process including CNC milling, grinding and turning.

Why do we sell our KM Tamper?

Espresso lovers and restaurants need a tamper for preparation. We have tested numerous tampers in our cafes in Basel over the years, and we also gain experience with various models in our coffee academy courses. Our baristas, Felix (German Barista Champion) and Philipp (two-time Swiss Champion), also have high demands on a tamper.

Challenges with conventional tampons:

Inconvenient bumps and tampers that cannot be straightened or create a vacuum can quickly become frustrating – especially after the hundredth espresso.

Our motivation:

These challenges motivated us to develop our own tamper that:

• Is well thought out and incorporates our accumulated experience.
  
• Produced locally and in a resource-saving manner .
  
• Aesthetically pleasing

Regular use:

• Vacuum prevention: The design of the base prevents negative pressure when tamping, so that the coffee puck is not damaged when removed.
  
• Straight tamping: The flush finish with the portafilter opening enables precise and straight tamping.
  
• Optimal compaction: With a diameter of 58.5 mm, the coffee powder is compacted right up to the edge, which prevents channeling and thus enables even extractions.
