Precautions for drinking American coffee

Water temperature 1

In order to obtain the best extraction effect, the water temperature of the coffee pot should be kept at 90 to 96 degrees Celsius. If the temperature is too low and the refining is not enough, it will make the coffee insipid, and if the temperature is too high, it will make the taste worse. If you make coffee by hand, let the water boil, but don't cook too much. Before making coffee, turn off the heat source and let the water cool for one minute.

2. Enjoy the brewed coffee immediately.

Pour coffee into a warm mug or coffee cup and keep the temperature as long as possible. Cooked coffee will lose its best taste immediately, so only cook the required amount. Don't leave the coffee on the electric stove for more than 15 minutes, or it will smell burnt. If coffee cannot be used immediately, it should be poured into a warm isolation thermos and drunk within 45 minutes.
