Finally, the tips on how to make a delicious cup of coffee beans are summarized as follows:

(1) use the freshest coffee beans.

It is best to grind before brewing.

(2) use fresh water.

Filtered or bottled water may be used in some areas and unfiltered water may be avoided.

(3) use the grinder correctly.

If you grind it too fine, the coffee will taste bitter; if it is too thick, the coffee will be light.

(4) use the standard amount of coffee.

Usually, the common ratio of coffee powder to water in western countries is 15 milligrams of coffee powder (one to two tablespoons): 300 milliliters of water (six ounces). Coffee lovers often take the upper limit of this ratio, but the amount can be adjusted according to personal taste and experience. And please pay attention to make appropriate adjustments according to the thickness of coffee powder.

(5) the temperature of the water should be just below the boiling point of 93 degrees Celsius.

Proper water temperature is also crucial. The choice of water temperature is related to cooking utensils, coffee bean species, coffee bean baking degree, the water temperature is too low, the flavor of coffee beans can not be fully extracted; water temperature is too high, excessive extraction, taste deterioration and often bitter.

(6) the brewing time should be completed within 4-6 minutes.

The best way to use "hand brewing" is within 4-6 minutes; using "mocha kettle" and "siphon Saifeng kettle" brewing method can be completed within 4 minutes; using "electric circulation filter" brewing time should not exceed 6 minutes, coffee will taste bitter for too long.

In addition, if the water passes through the coffee powder only once, the finished product will mainly contain soluble substances (including caffeine); if the water circulates through the coffee powder many times (like a common circulating filter), the less soluble substances in coffee beans will also enter the finished product, resulting in bitter taste, so this method is not favored by enthusiasts.

Remind everyone that continuous heating destroys the flavor of brewed coffee, so keeping it warm is often a failure, and degradation can also occur at room temperature, so "drinking while it is hot" is a necessary condition for tasting delicious coffee.
