Make a cup of fine coffee, make coffee at home, learn coffee, learn coffee knowledge.

1. Storage temperature

When your coffee beans need to be stored, long-term storage will slowly reduce the flavor of the coffee beans. But most importantly, do not use cold or frozen methods to store your coffee beans, drastic temperature changes will greatly damage the taste and aroma of coffee beans.

two。 Fresh grinding

A good cup of coffee must use freshly ground coffee powder, because once the coffee beans are ground into coffee powder, the oil and aroma in the coffee will begin to volatilize quickly, so it is necessary to make fresh grinding. And it doesn't take much longer to grind a cup of coffee beans than it takes you to boil water.

3. The right temperature

The recommended water temperature is 90-93 degrees, in fact, most of the time you do not need a thermometer, when you boil the water, turn off the fire for more than a minute, the water temperature will basically drop to this temperature range. Too high water temperature will brew out the mixed smell of coffee, while too low water temperature can not release the taste of coffee.

4. To wash the filter paper

If you use hand-brewed coffee, be sure to brew your filter paper in hot water before brewing coffee, because whether it's bleached or unbleached filter paper, if you use them directly to brew coffee without rinsing, your coffee will have a strange smell similar to beer turning sour.

5. Try to taste black coffee.

When you have good coffee beans and good coffee utensils, make a cup of coffee and try to taste a cup of black coffee without any sugar or milk. If you try to accept its taste and keep trying a variety of high-quality coffee beans, believe me, you will be surprised to find out what a good coffee should taste like, and you will probably become a stubborn and addictive black coffee believer like me.
