If you want to drink a cup of coffee with charming flavor, you don't necessarily need to be good at choosing beans, but you need to pay attention to seven basic elements. A few simple words are a profound knowledge, and each accurate handling does not necessarily produce the same flavor. Therefore, you need to ponder over and over again to become a coffee master. Here are seven basic elements.

Fresh coffee beans: the life of coffee lies in its mellow and intoxicating flavor and aroma, while fresh coffee beans retain this elegant demeanor. generally speaking, coffee can be called fresh within 4 weeks after roasting, and then the original flavor of coffee has been oxidized and volatilized to leave 50%. Therefore, to taste coffee should grasp the freshness of coffee beans.

Coffee bean grinding: the best condition is to adjust the thickness of the coffee beans according to the brewing equipment before brewing the coffee, so as to show the perfect flavor of the coffee beans.

Water temperature: generally speaking, the most suitable water temperature for brewing coffee is about 88 ℃-94 ℃. If the water temperature is high or low, it will interfere with the flavor of coffee. If the water temperature is too high, the coffee will show scorched mixed flavor. If the water temperature is low, it is not easy to extract coffee flavor.

Water quality: sweet water can improve the sweetness of coffee and affect the smell of coffee. When brewing coffee at home, it is recommended to use a filter kettle to filter impurities, which can improve the flavor of the coffee. In addition, if you do not like the use of filtered tap water, you can also use clean mountain spring water instead, but a special reminder: please try to avoid using distilled water.

Brewing method: different brewing utensils and brewing methods will affect the flavor of coffee, even if the same blue mountain coffee beans are brewed into American coffee, espresso, Vietnamese coffee … And so on will show different changes, this is the knowledge of brewing coffee, but also the fascinating part of coffee.

Brewing utensils: if the coffee brewing machine can be properly maintained and used, even if it is not expensive coffee beans, after some skillful hands, it will become a fine drink. Coffee brewing machines and utensils must be cleaned and dried as soon as possible after use, and finally placed in a ventilated place to keep dry. Here is a reminder: coffee is different from tea, coffee does not need a "pot", if you have a pot, then the next time you brew coffee, even if you find coffee with musty or oleic acid flavor.

Brewing time: the brewing time of coffee will depend on the water temperature, brewing method, season and place. Wait for the change of factors, and accurately control the brewing time of coffee in order to get a delicious cup of coffee. If the pseudo-heat brewing time is too long, the coffee flavor will be more bitter and the release of caffeine will increase.
