Water quality and water temperature of brewing coffee

[water quality]

98% of a cup of hand-brewed coffee is water. Distilled water is the best choice for making coffee.

It is not recommended to use pure water to make coffee. Coffee made with pure water often tastes dull and lacks a sense of hierarchy. But do not use mixed brand mineral water or mixed brand barreled water, once there is a strange smell in the water, it will be more obviously magnified and reflected in the coffee.

[water temperature]

Water temperature is also an important indicator that affects the taste of coffee. Too high water temperature will make coffee bitter, while low water temperature will make coffee sour.

Recommendations:

Deep roasted coffee beans are suitable for 80-85 degrees, while medium and shallow roasted coffee beans are suitable for extraction at a water temperature of about 90 degrees.
