The key to high-quality coffee beans and delicious coffee

High-quality coffee beans are the source of sweet coffee.

A good coffee bean smells sweet and mellow, looks like plump and average particles, complete in shape, shiny and fragile by hand pressure (unbreakable by hand pressure is called "dead bean").

Coffee trees are evergreen tropical shrubs. Coffee is dark green at birth, goes through yellow and red, and finally becomes crimson. The pair of seeds it contains are "coffee beans". Coffee beans can have a strange smell and flavor only after being roasted.

Generally speaking, the baking time is short, the coffee beans are light brown and sour; when the baking time is long, the bitterness is aggravated and the color is dark brown. Coffee has five flavors: mellow, fragrant, sweet, bitter, sour, different varieties of coffee, each with its own emphasis on flavor, you need to choose the roasting level of response in order to exert its strange flavor to the best, such as Colombian coffee and Blue Mountain coffee on the scale of taste, generally medium roasting is better, while Indonesia's Mantenin must be re-baked in order to demonstrate its fragrant and bitter characteristics.

After opening, the purchased coffee should be put into a sealed can and kept at a low temperature. It is advisable to drink it as soon as possible to maintain the best quality.

There are many ways to warm the cup, which can be warmed in the dryer, soaked in a hot tank, or hot water poured into the cup.

To control the thickness, quantity and water of coffee powder, the novel coffee beans are used to make coffee with the best flavor. It takes 12 grams of coffee powder to build a scale cup of coffee (about 4 ounces). Generally acid beans are roughed and bitter beans are finely ground. When building light coffee, you can grind it thicker, while when making espresso, the coffee is ground more finely, and the feed ratio is also increased. There are many ways to brew coffee. The simplest way is to put the coffee powder in a filter bag and brew it directly with boiling water. The coffee produced in this way can retain the fine foam of coffee oil (one of the logos of good coffee), but it has a slightly sour taste. If you use a coffee pot to cook, pay attention to the use of mineral water, do not boil for too long. Another common siphon method requires the use of special utensils, siphon method of coffee acidity is light, but no coffee oil. Warm cup is the prerequisite for good coffee.

For a perfect cup of coffee, a warm cup accounts for at least 20% of the merit.

No matter how well the coffee is brewed, as long as it is poured into a cold cup, the temperature of the coffee will drop immediately, and the fragrance will offset more than half of it. When you warm the coffee cup in advance, not only the heat of the coffee can be retained, but the temperature of the cup is more suitable for brewing aroma, so that the fragrance of coffee can be completely released.
