What exactly is a good cup of coffee? I found that there are great differences in the definition of coffee in the cultural and historical background. The elders around me who are influenced by Japanese culture say that coffee is mellow and fragrant, that it is not bitter, and that it takes a few spoonfuls of sugar or cream to make a complete cup of coffee. Some coffee seniors once said that giving gifts for the Spring Festival a long time ago, sending beautifully packaged canned instant coffee was still a manifestation of life taste. Gradually affected by the entry of American chain coffee, people slowly began to drink Italian coffee such as kabu, latte and concentrate, and even developed a lot of creative drinks, but the average consumer is still quite strange to fine / fine coffee.

The third wave of coffee and food safety problems also make us want to know where the ingredients we put in our mouths come from, and begin to understand what kind of coffee is, what country it comes from, where it comes from, how high it is, how high it is, how to treat it, and so on. Just like the recent opening of Japanese beef imports, premium and beef are popular, and so is coffee. The price of Rosa coffee grown in Panama in the past has soared year after year because of its floral flavor and rich fruit flavors. While people are pursuing a higher quality of life, their knowledge and flavor of coffee are also constantly improving. the definition of good coffee is from the bitter and strong coffee in the past, and gradually people begin to like coffee with a balanced sweet and sour taste and a warm taste. It would be even better with the special flavor of the place of origin. The world of coffee is not absolute, there are too many factors that affect the flavor of coffee, can constantly explore the possibility, this is also the attraction of coffee.

.

Here are several factors that have a great influence on the brewing of Rosa Coffee.

"quality and temperature of water"

In fact, 98% of a cup of coffee is water, so the choice of water is very important! Water that is too soft or too hard is not suitable for brewing coffee. You can buy a water quality TDS pen to test the water used for brewing. TDS (total Total Dissolved Solids dissolved solids) of about 150 is suitable for brewing coffee. The brewing water temperature is too low to release all the flavor substances in the coffee, too high water temperature is easy to over-extract, there will be bad impurities astringent taste, it is recommended to try from the water temperature of 90 degrees. .

"the importance and fineness of fresh grinding"

After the coffee beans are ground, the flavor will slowly lose over time and air. To put it simply, it is like when eating sashimi, the chef or the chef may not start to deal with the fish until the guest orders. The same is true of coffee beans. Grinding coffee before brewing can retain the original flavor of the coffee as much as possible. I would advise my friends to buy a bean grinder if they want to make their own coffee at home, so that they can choose to buy ripe coffee beans instead of ground coffee powder, and grind the coffee beans before brewing at home to keep the coffee more flavor. Different brewing methods have a suitable degree of grinding, if it is Italian coffee, you need a fine degree of grinding, while hand-brewed coffee can be tried by medium or medium rough grinding. .

'The choice of cooking utensils'

Different coffee utensils have a great influence on the flavor of coffee, and now there are different preferences for hand-brewed coffee or soaked coffee such as French filter pots. The coffee brewed through the filter paper is relatively clean and refreshing, and the coffee through the metal filter has a more greasy feeling after soaking. Different cooking methods will also affect the cooking time, just like taking pictures, the shutter time is too short or underexposed, too long and overexposed, so the appropriate cooking time is also very important. It is recommended to try the flavor from 2 to 2 and a half minutes.

Of course, this time is not absolute, but also corresponding to the grinding fineness of coffee powder.

Adjustment of the ratio of coffee powder to water

Everyone has different standards for shade, but the trend we can see is that people will no longer pursue that black coffee should be strong and bitter in the past. Generally, the ratio of black coffee powder to water is from 1: 8 murmur10 in the past, that is, 1 gram of coffee powder will add 8-10 milliliters of water, to 1 gram of powder will add 12 murals of 15 milliliters, which is more important to drink comfortably and smoothly. You can refer to the coffee concentration and extraction rate according to the coffee gold cup extraction theory. The ideal extraction rate is 18 Murray 22%, and the coffee concentration is 1.15 Murray 1.35%.
