The skill of making a good cup of coffee.

From green beans to a cup of strong espresso, every step in between is very important and affects the quality of the final product. While you know how to choose the best and most appropriate coffee beans, you must also know which brewing method to use in order to achieve a perfect cup of coffee. Knowing how to make the perfect cup of coffee is like knowing how to use a painter's paintbrush or a scientist's understanding how to apply scientific equations. When you have this expertise, you can change from simple Espresso to fancy coffee drinks.

Here are some tips for you:

(1)Use the freshest coffee beans, shelf life of no more than a week, preferably before brewing before grinding.

(2)Use the grinder correctly. If ground too fine, the coffee will have a bitter taste; if ground too coarse, the coffee will be lighter.

(3)Using a standard coffee gauge, 2 tablespoons ground coffee with 168 grams of water; the amount can be adjusted to suit individual tastes and experiences.

(4)Use fresh water. In some areas, filtered or bottled water may be used. Avoid unfiltered water.

(5)The temperature of the water should ideally be just below the boiling point of 93 degrees Celsius. Drip cooking is best done in 4-6 minutes. Other good brewing methods include pressure infiltration brewing and vacuum pot brewing, which can be completed in 4 minutes. Use electric kettle brewing time should not exceed 6 minutes brewing method, brewing time too long coffee will produce bitter taste.
