Choosing the Right Coffee Beans

Selecting the appropriate coffee beans is crucial for crafting a quality espresso. The type of beans, their roast profile, and freshness all significantly impact the flavor and aroma of the final shot.

  • Type of Beans: Espresso is typically made from Arabica or Robusta beans, with Arabica offering a smoother and more complex flavor, while Robusta provides a stronger, more bitter taste.
  • Roast Profile: Medium to dark roasts are generally preferred for espresso, as they enhance the rich, bold flavors desired in a shot.
  • Freshness: Use freshly roasted coffee beans, ideally within two weeks of roasting. Grinding the beans just before brewing is also recommended to preserve their flavor.

Grinding the Coffee

The grind size of the coffee is a critical factor in brewing espresso. A fine grind is essential, as it allows for optimal extraction of flavors during the brewing process. The grind should resemble table salt, providing a balance between resistance and flow rate.

  • Grind Size: Adjust the grinder to a fine setting.
  • Consistency: Ensure that the grind is uniform to prevent channeling, which can lead to uneven extraction.

Measuring the Coffee

Accurate measurement of coffee grounds is necessary to achieve the perfect shot of espresso. The standard amount for a double shot is approximately 18-20 grams of coffee.

Shot Type Coffee Weight (grams) Yield (ml)
Single Shot 9-10 30
Double Shot 18-20 60

Using a digital scale will ensure precision in measuring your coffee.
