Espresso Coffee Machine: How to Make Espresso at Home

For coffee lovers nothing can be more exciting than making espresso at home with your new espresso coffee machine.  Espresso is a concentrated coffee beverage.  It is brewed by forcing hot water through finely ground coffee at a high pressure.

Espresso has a thicker consistency than other coffee brews, with a characteristic crema or foam on top.

The pressurized brewing process used in espresso machines produces a brew with a very high concentration of dissolved solids and flavors.  This makes espresso the perfect base for other coffee beverages such as lattes, mochas, cappuccino, macchiato, and americanos.

To make the best espresso at home with your new espresso coffee machine, you must start with very finely ground coffee.  Producing a shot of espresso is often called “pulling” a shot.  When you do this on your espresso coffee machine, a steady stream of brewed espresso coffee should come out evenly, with a light and creamy froth floating on top.  A single shot of espresso is 30 milliliters while a double shot is 60mL.

You will need about 2 teaspoons of ground espresso for a single shot, or between 7 and 10 grams.  A double shot requires between 12 and 18 grams or about 4 teaspoons.  Pour the ground coffee into the espresso filter basket.

Use a metal tamper to tamp the espresso into a dense puck.  The ground espresso should lie flat across the filter basket.

Attach the filter basket to your espresso machine and lock it in place.  Position a small espresso cup or demitasse underneath the filter basket.

Press the button for a “short pull” or a “long pull.”  The “short pull” button produces a very thick, syrupy espresso with stronger flavor.  The “long pull” button puts more water and the espresso produced is not as dense.

When the brewing process starts, hot water at 92°-96°C is forced through the ground coffee under a pressure of 9 bars.  If the water is too cool the espresso will taste sour.  If it’s too hot, the coffee will be bitter.  To make a good cup of espresso at home, your new espresso coffee machine should be able to maintain the water temperature within 1 or 2 degrees of the ideal temperature.

During the brewing process the oils and flavors in the ground coffee are extracted and emulsified.  This produces a thick, rich beverage.  It usually takes 25 to 30 seconds for the water to pass through the ground coffee puck and into the receiving cup.  Making the best espresso at home with your new espresso coffee machine requires the right fineness of the ground coffee, tamping, and maintaining the ideal pressure and temperature of the water.

To savor your demitasse of espresso at its best, serve immediately and drink as soon as possible.  As an alternative, you can use the espresso to prepare cappuccino, lattes, macchiato or americanos.
