Selection of Water temperature of dripping filter Paper selection and use of hand dripping filter paper for coffee

Water temperature

The effect on taste

Above 88 °C

If the water temperature is too high, it is easy to produce bubbles, resulting in incomplete steaming.

88 °C ~ 84 °C (suitable for deep and moderate baking)

The taste is strong and the bitter taste is obvious.

84 °C ~ 82 °C (suitable for all baking degrees)

The taste is even.

82 °C ~ 77 °C (suitable for deep baking)

It can suppress the bitterness.

Below 77 °C

The water temperature is too low, steaming is not complete, and the extraction is insufficient.

The freshness of beans needs to be adjusted accordingly:

Freshly baked beans. At this time, the beans are still emitting a large amount of carbon dioxide, and if the coffee powder is injected with hot water above 90 °C, it will emit a lot of foam and destroy the steaming layer. Therefore, freshly baked beans should be slowly extracted at a temperature below 80 °C. Beans baked for more than two weeks. At this time, the beans are not fresh enough, and the high temperature above 90 °C is needed to effectively extract enough active ingredients.

The water temperature also needs to be adjusted with different baking degree:

Usually deep baking is suitable for slightly low temperature (75 °C ~ 79 °C) or medium temperature (80 °C ~ 82 °C), and shallow baking is suitable for medium temperature or slightly high temperature (83 °C ~ 85 °C).

As long as you master the right method, you will be able to make the acidity and bitter coffee you want.
