Slingshot Espresso Grinding and Automatic Tamping Systems

Slingshot is an Australia-based coffee equipment brand focused on the repeatability of grinding and tamping in busy espresso bars. Its range includes the Dosis, Sisma, Talis and Baby Talis coffee grinders along with the Kilo automatic tamper.

In espresso preparation, the grinder and tamper should not be considered independently of each other. The coffee amount and particle structure delivered by the grinder, together with tamp pressure, form the coffee bed's resistance. Equipment selection should be based on order intervals during busy hours as much as on daily consumption.

Dosis Volumetric Dosing System

The Dosis uses a volumetric dispensing system aimed at maintaining a target coffee dose as the setting is adjusted finer or coarser. The brand describes this delivery mechanism as a patented system. The model offers 64 and 75 mm flat burrs along with a 68 mm conical burr option.

Rather than delivering coffee based only on a fixed grinding time, volumetric dosing tries to manage the volume of ground product. When bean density and roast level change, gram output should still be checked with a scale.

The Dosis offers an approach aimed at reducing how much dose setting and grind setting affect each other, particularly in cafés preparing large numbers of espressos in a short time. It does not fully eliminate the need for daily calibration.

On-Demand Grinding on the Sisma and Talis

The Sisma uses a 75 mm flat burr, a 1.2 kg bean hopper, micrometric adjustment and a programmable dosing system. Alongside on-demand operation, the model offers an Auto Mode that prepares pre-ground doses for busy hours.

The Talis is also a 75 mm flat-burr on-demand grinder. It offers hopper options of approximately 1.2 or 1.6 kg. A larger hopper allows less frequent refilling, but beans sitting on a hot grinder for a long time should be considered from an aroma and temperature-management standpoint.

The Baby Talis, with a more compact body and a 64 mm flat burr, is aimed at lower-volume bars. When choosing a grinder, not just the body size but also weekly coffee consumption and back-to-back grinding load should be taken into account.

3–30 Kilogram Pressure on the Kilo Automatic Tamper

The Kilo automatic tamper applies a downward force to the coffee bed in the portafilter, programmable between 3 and 30 kilograms. Its internal load cell measures force in real time, helping repeat the selected tamp profile.

The user can program between one and three tamp movements for a single coffee bed, and use different pressures across the movements. It should not be assumed that a multi-tamp option gives a better result for every recipe. Espresso flow and coffee-bed behaviour should be tested.

Tamping heads are offered in different sizes such as 58.4, 58, 54.3 and 53 mm. Head diameter must match the portafilter basket. A head that is too small can leave uncompressed coffee at the edges.

Featured Highlights

• The Dosis series offers 64 and 75 mm flat burrs along with a 68 mm conical burr option.
• The Sisma and Talis are aimed at 75 mm flat-burr on-demand grinding systems.
• The Kilo automatic tamper can program pressure between 3 and 30 kilograms and up to three tamp movements.
• The load cell helps repeat tamp force through real-time measurement.

Positioning the Slingshot System in an Espresso Bar

The grinder and tamper should be positioned near the espresso machine so the barista can use the portafilter in a single-direction movement. Sufficient clearance should be left above the units for hopper refilling and burr cleaning.

The Kilo head must be parallel to the portafilter basket. Grinder output should also be set so the coffee falls into the centre of the basket. Uneven distribution cannot be corrected by tamp pressure alone.

Dose weight, espresso time and output weight should be measured every shift. When beans change, grind setting, dose and tamp profile should be reassessed together.

Frequently Asked Questions

What is the difference between the Slingshot Dosis and Sisma?

The Dosis focuses on dose consistency independent of grind setting through its volumetric delivery system. The Sisma offers programmable on-demand grinding and an Auto Mode for busy hours. Burr choice and operating method should be evaluated based on business volume.

How much tamp pressure does the Slingshot Kilo apply?

The Kilo model can be programmed for downward force between 3 and 30 kilograms. Force is measured with a load cell. The appropriate pressure should be tested according to the espresso recipe and basket structure.

Should you choose a 64 mm or 75 mm Slingshot grinder?

A 64 mm burr is aimed at more compact, medium-volume use, while a 75 mm burr is aimed at more intensive back-to-back grinding needs. The number of espressos during the busiest hour should be calculated before the daily total.
