The Six Golden Elements for Extracting a Perfect Espresso

When looking for coffee machines, you will often see information about the six golden elements for extracting a perfect espresso. Here, we have compiled this information as a record.

The Six Golden Elements for Extracting a Perfect Espresso

Espresso Machine

This is where all the results and essence of coffee making converge. The precision design and manufacturing of coffee machines hold a very important position in the production of espresso.

Water Quality

Water is the main component of coffee, and for this reason, we cannot overlook this important ingredient. The formation of scale occurs when calcium and magnesium ions crystallize under the catalytic effect of heat. Today, there are specific tests that can detect the calcium and magnesium carbonate content in water. This test is known as the "water hardness coefficient" or "KH".

Coffee Beans

Roasters select coffee beans based on origin and variety to ensure consistent quality. Roasting techniques directly affect the taste of coffee.

• Light Roast: Slightly acidic, less bitter
• Dark Roast: Less acidic, more bitter

Coffee Grinder

The coffee grinder is an important foundation for making a good espresso. It is an essential tool for the coffee machine that determines the quality of the grind. Coffee should be ground very finely so that the average flow time for two espresso shots is approximately 25-30 seconds.

Coffee Cup

The coffee cup used to hold espresso should be stored at a temperature of around 40 degrees Celsius.

What is Pre-infusion?

During the coffee extraction process, 10-15 cc of hot water is first injected into the coffee grounds and allowed to soak for about 3-5 seconds, allowing the coffee grounds to be pre-infused.

Then, the extraction process begins. In this way, the coffee (CREMA) extraction will be more complete and smooth, with better taste and richer layers of coffee flavor.
