HOW TO MAKE ESPRESSO COFFEE

TIPS FOR A HOTTER COFFEE
For hotter espresso coffee, you can do the following:

• Attach the filter holder to the appliance with the filter in place but without adding coffee.
  Using the same cup that you will later use for coffee, press the 1 cup button and deliver hot water into the cup to heat it.
• Rest the cup you will be using under the hot water spout, turn the dial to the hot water position. and deliver hot water into the cup to heat it.

HOW TO MAKE ESPRESSO COFFEE USING PRE-GROUND COFFEE

1. Align the protrusion on the coffee filter with the notch on the filter holder and turn it clockwise (fig. 13).
   
2. To make one coffee, place one level measure of pre-ground coffee (about 7 g) in the filter. To make two coffees, place two loosely filled measures (about 14 g) of pre-ground coffee in the filter (fig. 14).
   
   Before filling with pre-ground coffee, make sure there are no coffee residues left in the filter from the last time you made coffee.
   
3. Gently tap the sides of the filter a few times to distribute the coffee until it appears flat. You can also use your fingers to distribute the coffee evenly (fig. 15).
   
4. Press lightly with the tamper. Ensure the coffee is below the MAX. line (fig. 16).
   
   Note: Correct pressing of the pre-ground coffee is essential to obtain a good espresso. If you press too firmly, the coffee will be delivered slowly and will be strong. If you press too lightly, the coffee will be delivered quickly and will be weak.

5. Remove any excess coffee from the rim of the filter holder and attach the filter holder to the appliance. To attach correctly, align the filter holder handle with the UNLOCK symbol (fig. 17), attach the filter holder and rotate the handle towards the right until aligned with the CLOSE symbol (fig. 18)

TIPS FOR BREWING THE PERFECT ESPRESSO

• The filter should be clean.
  Before dosing the coffee to your filter, make sure that the filter is clean and tidy. Both moisture and leftover grounds might (and most likely will) make your future espresso taste over-extracted = astringent and bitter.

• Always preheat the equipment (machine, cup and filter).
  Because espresso is a very small volume of liquid, it loses its heat very quickly, especially when it comes in contact with a larger mass of something cold. To avoid this, preheat both the filter and the demitasse cups using hot water.
• Soften the water you are using to make the espresso or use bottled distilled water.
  The quality of your espresso or coffee has a lot to do with the quality of the water you use to brew, always use filtered water when brewing espresso. Not only will it improve the flavor, but it will keep the plumbing inside your espresso machine clean.
• You Should Buy Freshly Roasted Beans
  Like most foods, coffee is best when fresh. Try and buy beans that have been roasted within the last week or two. After two weeks, coffee starts to go stale. It becomes less and less flavorful, and you'll notice that it's harder to achieve a dense layer of crema on your espresso.
  For best results, try to use 100% Arabica beans. Robusta is strong, but is usually of poorer quality, having a harsher flavor.
  If you are buying pre-ground coffee, try not to buy more than you can drink in a week. You can stretch this to two weeks by investing in a good coffee storage container that you keep in a cool, dark place.

• Grind Size Matters
  If you've mastered the espresso technique, the time has come to go from pulling good shots to pulling great shots, which means dialing in your grind size. Grind too coarse, and water will gush through, leaving a watery and astringent shot. Grind too fine, and water will seep through, resulting in a tiny pool of intensely bitter brew.

• Get the correct dose
  Use gram scales to weigh your dose and shots. It's always better to measure your coffee by weight than by volume. This is the only way to ensure you're using the exact same amount of coffee every time. A rough guideline is to use 7 to 9 g for a single shot and 13 to 15 g for a double shot.

• The extraction time should be 25-30 seconds. Adjust the grind if it is not.
  Espresso is made by forcing hot water (not boiling water) under pressure through a lipuckll of finely ground coffee. The finer the grind, the denser the puck, hence the more pressure required to force the water through it. The most important rule of making perfect espresso is that the pressure used should push the water through the coffee puck in 25-30 seconds. If it takes longer than this, the espresso will be bitter.
• Tamp the coffee grind evenly into the filter.
  Tamp the coffee in the filter with the tamping tool, using an even motion. The tamped coffee should be level and compacted. Brush off any loose grounds. If you want to guarantee tamping consistency and have the budget, invest in a calibrated tamper. These ensure you apply the same force every time.
