COFFEE MAKING TIPS & PREPARATION

PRE-HEATING

Heating your cup or glass

A warm cup will help maintain the coffee’s optimal temperature. Pre-heat your cup by rinsing with hot water from the hot water outlet and place on the cup warming tray.

Heating the portafilter and filter basket

A cold portafilter and filter basket can reduce the extraction temperature enough to significantly affect the quality of your espresso. Always ensure the portafilter and filter basket are pre-heated with hot water from the hot water outlet before initial use.

NOTE

Always wipe the portafilter and filter basket dry before dosing with ground coffee as moisture can encourage ‘channeling’ where water by-passes the ground coffee during extraction.

Dual Wall Filter Baskets

Use Dual Wall filter baskets if using pre-ground coffee.

Dual Wall filter baskets regulate the pressure and help to optimize the extraction regardless of the grind, dose or freshness.

NOTE

Regardless of whether you use Single Wall or Dual Wall filter baskets, use the 1 CUP basket when brewing a single cup and the 2 CUP basket when brewing two cups or a stronger single cup or mug.

DOSE and TAMPING

•Wipe filter basket with a dry cloth.

•If using Single Wall filter baskets, grind just enough coffee to fill the filter basket. You may need to experiment with how long the grinder needs to run to achieve the correct dose.

•Tap the portafilter several times to distribute the coffee evenly in the filter basket.

•Tamp down firmly (using approx.

30-40lbs or 15-20kg of pressure). The amount of pressure is not as important as consistent pressure every time.

•As a guide to dose, the top edge of the metal cap on the tamper should be level with the top of the filter basket after the coffee has been tamped.

•Rotate the Razor™ dose trimming tool back and forth while holding the portafilter on an angle over a knock box to trim off excess coffee grinds. Your filter basket is now dosed with the correct amount of coffee.

•Wipe excess coffee from the rim of the filter basket to ensure a proper seal is achieved in the group head.

TIP

If the extraction is too fast, make the grind finer & repeat above steps. If the

should be fine but not too fine. The grind size will affect the rate at which the water flows through the ground coffee in the filter basket and the taste of the espresso.

If the grind is too fine (looks like powder and feels like flour when rubbed between fingers), the water will not flow through the coffee even when under pressure. The resulting espresso will be OVER- EXTRACTED, dark in color and bitter in flavor.

If the grind is too coarse the water will flow through the ground coffee in the filter basket too quickly. The resulting espresso will be UNDER-EXTRACTED and lacking in color and flavor.

TRIMMING THE DOSE

The Razor™ precision dose trimming tool allows you to trim the puck to the right level for a consistent extraction.

Precision dose trimming tool

•Insert the Razor™ dose trimming tool into the filter basket until the shoulders of the tool rest on the rim of the basket. The blade of the dose trimming tool should penetrate the surface of the tamped coffee.

PURGING THE GROUP HEAD

Before placing the portafilter into the group head, run a short flow of water through the group head by pressing and holding the

1 CUP button. Allow water to flow for

5 seconds, then release the 1 CUP button to stop the flow of water. This will purge any ground coffee residue from the group head and stabilize the temperature prior

to extraction.
