Secret recipe for Italian espresso
First of all, we define espresso as a 30ml cup of coffee made from an Italian espresso machine.
Usually we use 7-9 grams of precision ground, evenly pressed coffee powder to make 30 milliliters of espresso. The purified water will be heated to 92 ℃ and the coffee will be extracted at a pressure of 9 bar for 25-30 seconds.
Coffee powder should be made into a tight, flat pressed powder, and there should be a 1 mm gap between pressed powder and the outlet. Hot water from the coffee machine should be sprinkled evenly on the surface of pressed powder. The essence of coffee is released quickly after contact with water, filling a 1 mm gap and forcing the water to extract coffee more evenly.
