To get a satisfying cup of espresso, the choice of coffee beans, dose, liquid weight ratio, extraction time, grind size, water temperature, and pressure—each one affects the final flavor. Although using single-origin coffee beans to make espresso has been popular in recent years, for friends who are just starting with espresso extraction and have limited experience, starting with blended coffee beans is more reliable.

Advantages of Espresso Blend Coffee Beans

Coffee itself is an agricultural product, and the terroir conditions and climate each year can cause fluctuations in flavor performance. The idea of blending is precisely to avoid the shortcomings that single-origin coffee beans may expose under high-pressure extraction, combining beans from different origins and flavor directions in certain proportions, leveraging strengths to offset weaknesses, and then through medium-dark roasting, allowing the espresso to maintain richness and stability over a longer period.

Front Street Coffee currently sells 4 coffee beans with different flavor characteristics, and you can choose according to your taste preferences.

Precautions for Making Espresso

Different coffee machines and grinders have different performance and behavior, and pressure levels and grind settings will vary, so there is no universally applicable grind parameter. Here, Front Street's dark-roasted, rich-crema commercial blend coffee beans are used as a reference.

At the initial stage, Front Street Coffee suggests first using a set of middle-of-the-road extraction parameters, then making fine adjustments based on the actual taste: 20 grams of grounds, extracted at a 1:2 ratio and 9 bar pressure to get 40 grams of coffee liquid, with time controlled between 25 and 30 seconds. After extraction is complete, make targeted adjustments based on the flavor performance.

Changes in grind size and extraction time will directly reflect in the taste of the espresso. The coffee machine is quite sensitive to the grind level: if the grind is slightly coarser, the flow rate will be faster, extraction time shortens, and the mouthfeel appears thin; if the grind is slightly finer, the flow rate will be slower, extraction time lengthens, and the taste easily becomes bitter and burnt.

Espresso Extraction Steps

1. Grinding and Dosing

Before formally dosing, Front Street suggests first grinding 1 gram of coffee beans to clear out residual grounds in the grinder. Then wipe the portafilter clean, ensuring the basket is dry and has no residual grounds. After that, turn on the grinder switch to start grinding, and use the basket to catch the falling coffee grounds.

2. Distribution & Tamping

Distribution is to make the coffee grounds evenly distributed in the basket. Front Street Coffee suggests using a distribution tool to complete this, which is easier for beginners to ensure stability and efficiency. Place the distribution tool flat on the basket, rotate a few times, and lift it up.

The purpose of tamping is to expel air between particles and increase the density of the puck so that it can withstand the impact of high-pressure water flow. When tamping, the force and direction should remain perpendicular to the basket. A relatively reliable method is to keep the arm vertical and use the arm's strength to press down. The force does not need to be too great; just press the puck down to the recessed line inside the basket.

3. Flushing the Group Head

Before extracting each espresso, there is no need to rush to lock in the portafilter. First turn on the switch and let the water accumulated on the group head shower screen drain away; this helps ensure the water temperature remains consistent throughout the extraction process.

4. Lock the Portafilter Tightly and Quickly Press the Extraction Button

Gently lock the portafilter onto the group head, and be sure to confirm it is tight to avoid water leakage. After locking, immediately press the brew button to prevent the high-temperature group head from scorching the surface of the coffee grounds. About 4 seconds after pressing the extraction button, thick coffee liquid begins to seep from the bottom of the basket, and then several thin streams gradually merge into one liquid column, with the color shifting from dark brown to golden.
