What Is a Double Shot Espresso?

A double shot espresso, commonly referred to as a "doppio," refers to a coffee drink made by forcing a small amount of nearly boiling water through finely-ground coffee beans under high pressure. Specifically, a double shot uses about 14 to 18 grams of ground coffee to produce approximately 60 milliliters (about 2 ounces) of concentrated coffee. This is twice the amount used for a single espresso shot, which typically uses about 7 to 9 grams of coffee for about 30 milliliters (1 ounce) of drink.

Double shot espressos are known for their rich flavor and higher concentration of caffeine compared to a single shot. They serve as the foundation for other popular coffee drinks such as lattes, cappuccinos, and Americanos, where they are diluted with milk or water respectively. The process and the precise amount of coffee and water can vary slightly depending on the preferences of the barista or the specific practices of a coffee shop.

Essential Equipment and Ingredients for Making a Double Shot Espresso

Before learning how to make a double shot of espresso, you need the right tools and ingredients to achieve perfect results. Here’s what’s essential for your setup:

  • Espresso Machine: A quality machine capable of reaching 9+ bars of pressure. The SCHWUA Espresso Machine, with its 20 BAR pressure extraction and easy one-touch control panel, ensures maximum flavor and simplicity in brewing.
  • Coffee Grinder: A burr grinder is preferred for even and adjustable grinding.
  • Fresh Coffee Beans: High-quality beans, often a dark roast, specifically meant for espresso.
  • Tamper: To evenly press the coffee grounds in the portafilter.
  • Filtered Water: To ensure clean, pure water for the best flavor.
  • Scale: For precise measurement of coffee grounds.

How Do You Make a Double Espresso?

Brewing a double shot espresso requires precision and attention to detail. Follow these steps to achieve espresso perfection.

Step 1: Heat the Espresso Machine

Turn on your espresso machine to heat it up. Most machines should be allowed to warm up for about 15 to 30 minutes to ensure the water and the machine parts are at the ideal temperature.

Step 2: Grind the Coffee

While the machine is heating, grind your coffee beans to a fine espresso grind. You'll need about 18 grams of coffee for a double shot.

Step 3: Measure and Tamp the Coffee

  • Place the portafilter on the scale and tare it to zero.
  • Add the ground coffee to the portafilter basket. Use the scale to ensure you have the correct amount (about 18 grams).
  • Once filled, evenly distribute the coffee grounds in the basket and then tamp firmly. The tamping should be even and straight to ensure uniform extraction.

Step 4: Pull the Espresso

  • Lock the portafilter into the espresso machine.
  • Place a pre-warmed demitasse cup under the portafilter.
  • Start the shot and use a timer. A typical double shot takes about 25 to 30 seconds to brew.
  • Watch as the espresso drips out. It should start slowly, with the coffee looking thick and dark, gradually becoming lighter in color, known as the "blonding" of the espresso. Stop the shot once you reach about 60 milliliters.

Step 5: Serve

Serve the espresso immediately for the best flavor. An ideal double espresso has a thick golden crema on top.

Tips for Perfecting Your Double Shot Espresso

When making double espresso coffee, even small adjustments can significantly impact the quality of your espresso. Here are some tips to help you perfect your double shot:

  • Use Fresh Coffee Beans: Use freshly roasted coffee beans for the best flavor, ideally within two to three weeks of roasting. Store them in an airtight container, away from light, heat, and moisture to preserve their freshness.
  • Grind Size and Consistency: Ensure your coffee grind is very fine, similar to powdered sugar. Adjust the grind size if shots pull too quickly (coarser) or too slowly (finer). Use a burr grinder for consistent grind size, essential for even extraction.
  • Proper Dosing: Measure your coffee grounds accurately using a scale. For a double shot, typically use about 18 grams of coffee to ensure consistency and optimal flavor extraction.
  • Tamping Technique: Tamp the coffee grounds evenly and with consistent pressure to ensure uniform extraction. A good tamp should be firm, around 30 pounds of pressure, and level to prevent channeling where water finds weak spots and flows through too quickly.
  • Extraction Time: Aim for an extraction time of about 25 to 30 seconds for a double shot. Timing your shot ensures that the coffee is neither under-extracted (sour and weak) nor over-extracted (bitter and harsh). Adjust grind size and dose as needed to hit this target.
  • Machine Maintenance: Regularly clean your espresso machine to ensure optimal performance. Residual oils and coffee grounds can affect the flavor and consistency of your espresso. Descale the machine periodically to remove mineral buildup, especially if you use hard water.
