The method of brewing coffee beans introduces the technique of pressing coffee powder.

Brewing of coffee beans

The process of dissolving out the water-soluble components of ground coffee in any way can be called brewing or extraction, just like coffee beans, no kind of coffee is flawless, and the extraction of coffee is the same. no method is flawless.

In a cup of coffee, water accounts for more than 98%. Choosing the appropriate water quality is the first condition for brewing coffee, which contains moderate carbon dioxide and calcium. The purified water of magnesium is helpful to the extraction of good quality content to a certain extent, and the behavior of groundwater / tap water / mineral water / distilled water is arranged in order according to the taste of taste, but both groundwater and tap water need secondary purification to be ideal. as for mineral water and distilled water, some experts call it boring water, which has a certain negative effect on the balance of taste.

Proper grinding is also related to the success or failure of a cup of coffee. Due to the large contact surface between fine grinding and air, in addition to accelerating its oxidation, once combined with water, the speed of dialysis is several times faster than that of rough grinding. At this time, the adjustment of brewers in time and water temperature is related to the success or failure of a cup of coffee. No matter what kind of cooking method, using the simple formula, that is, the water temperature is directly proportional to the grinding thickness and inversely proportional to the heating time, the personal conditioning method in the process of washing and adjusting involves the impact of water molecules and fiber, and also fully affects the equilibrium of extraction. The moderate water temperature is about 90.5 ~ 96 degrees Celsius (except Espresso), and the suitable extraction rate is about 18% 22%. In other words, it is suitable for most cooking methods in the workshop. The benign ingredients are extracted completely and the inferior contents are retained in the fiber quality, which is the perfect presentation of a cup of coffee.

Italian espresso

The topic that is most worried about leaving controversial discussion on the message board is Espresso. What does Espresso mean? A way of extracting coffee, an alternative blend of coffee, a special method of baking, a unique way of drinking, an indescribable art. , all of the above.

Any way of extraction is difficult to compare with pure espresso, rich and rich, and moderate pressure makes the appropriate water temperature quickly pass through the coffee powder, emulsifying the natural benign oil and rich protein in coffee, like slightly sweet chocolate, swimming in the mouth, slowly extending, sweeping the whole sense of taste, therefore, Taiwan has inherited the Japanese coffee culture for nearly 40 years. It unexpectedly gave Italian coffee a place in just a few years, and greatly changed the local coffee culture. Fresh coffee beans, suitable fine grinding / water temperature / pressure / ratio, satisfy many gluttons, but also set off a passionate discussion among experts. In short, a good thing.
