## Long description

Rhinowares Thumpa is a black portafilter tamper with an overall length of 860 mm, designed to provide compact, consistent tamping of coffee grounds. The tool features a purpose-built tamping base and an ergonomic profile that help create an even coffee puck and promote uniform extraction. Intended for use with standard portafilters, this tamper is suitable for both professional and home espresso preparation where reliable, repeatable tamping is required.
Advantages
The Rhinowares Thumpa offers consistent tamping force and a stable base geometry to minimise channeling and uneven extraction. Its compact design and black finish make it easy to position and visually unobtrusive at the espresso station. The tamper’s length supports good leverage and control, enabling repeatable pressure and uniform puck formation across multiple extractions.
Suitable for
Professional espresso bars requiring repeatable tamping for consistent shots
Home espresso machines where compact, reliable tamping is desired
Baristas training to achieve uniform puck density and extraction
Use with standard portafilters that match the tamper base dimensions
Key specifications
Colour: black
Overall length: 860 mm
Tamping base: fit-for-purpose design to support even puck formation
Intended use: manual tamping of ground coffee in portafilters
Ergonomics: compact profile for controlled leverage and repeatable pressure
How to use
Place the portafilter on a stable surface or in a tamping station and fill the basket with an even dose of ground coffee. Hold the Rhinowares Thumpa vertically above the portafilter and apply steady, even pressure until the tamper base makes full contact with the coffee bed. Keep the wrist straight to maintain consistent force, then withdraw the tamper and wipe any excess grounds from the portafilter rim before brewing.
Usage recommendations
Use a calibrated technique to ensure repeatable pressure across shots; combine the tamper with a level dosing and distribution method for best extraction consistency. Clean the tamper regularly and avoid dropping or striking the base to preserve its geometry and ensure long-term consistent performance.
