Relationship between water temperature of hand-brewed coffee and extraction tools and freshness of coffee beans

Recently, many friends have begun to make coffee by hand at home.

Will start asking how to make a good cup of coffee.

The main factors affecting coffee brewing include the freshness of beans, the ratio of coffee beans to water, extraction time, water temperature, grinding degree of coffee beans, and even water quality.

These factors complement each other.

Continue the extraction mentioned earlier.

The water temperature to be raised this time, that is, the extraction temperature.

Take hand-brewed coffee as an example

First of all, we should decide the ratio of brewed coffee beans to water.

The next step is to grind the coffee beans to the thickness of the hand-washed filter paper.

The next step is to control the extraction water temperature.

The roasting degree of coffee beans is related to the water temperature.

If the coffee beans are roasted more deeply

Then the water temperature is a little lower than that of shallow baked beans.

Why?

Because deep-roasted coffee beans have more carbides.

High water temperature can easily highlight the bitter and scorched taste of coffee beans.

Relatively, the medium and light roasted coffee beans are rich in sour aroma.

Too low water temperature will only make coffee beans taste uncomfortable acidity and appear dry (that is, insufficient extraction due to insufficient water temperature).

Therefore, the water temperature of coffee beans roasted in deep brewing is a little lower, while the water temperature of coffee beans roasted in medium and light degree is a little higher. Generally speaking, the water temperature is about 85 to 92 degrees.

In addition, when the water temperature is higher, the extraction time should be shortened to avoid excessive extraction.

Then quickly learn about the changes in coffee brewing temperature and taste through the table:

Water temperature

Suitable baking degree

The change in the taste of coffee

Above 96 °C

X

If the water temperature is too high, it is easy to produce bubbles and cause partial steaming, which will make the bitterness more intense.

90 °C ~ 95 °C

Deep baking, medium baking

The water temperature is slightly higher, the taste is stronger and the bitterness is more obvious after cooking.

83 °C ~ 89 °C

All baking degrees

For the filter paper dripping method, 83 °C ~ 86 °C is the right temperature, showing a relatively average taste.

77 °C ~ 82 °C

Deep baking

The temperature of the water is slightly lower, restraining the bitterness, but the taste is sour.

Below 76 °C

X

The water temperature is too low to brew the aroma of coffee.

The editor usually measures the water temperature when making coffee at home.

I probably think about the temperature at which the coffee beans used today should be boiled.

A lot of experiments, you will also know more about your favorite taste!
