Methods of steaming and water injection of hand-brewed coffee data of water temperature and powder-to-water ratio of hand-made coffee

Some water temperature data of hand-brewed coffee ℃

As the weather turns cold, I feel that the temperature of hand-brewed coffee is not warm enough. In fact, there are some fixed brewing processes that can increase the temperature of hand-brewed coffee.

Today, a K-type digital thermometer is used to monitor the change of hand temperature.

First of all, the K-type TM-905A has a cross wire knob to fine-tune the temperature correction, which is generally best corrected by boiling boiling water.

When boiling in a fast-boiling furnace, it may be more than 100 ℃ (boiling steam), so the temperature within 20 seconds of about 10 ℃ after boiling is exactly 100 ℃ as the standard temperature.

When boiling water is poured into this 350ml stainless steel thin spout pot, the water temperature will drop to 92 ℃, or you can pour more water as a warm cup of boiling water.

When the warm cup is finished, pour in eight-tenths of full water and keep the boiling water temperature of 91Mel 92 ℃ like a small spout pot.

When brewing half of the coffee is extracted in the filter cup, the environment of the extracted coffee is about 85 ℃, and the coffee will be stable.

At the end of brewing, the temperature of the coffee extracted by 85 ℃ will be maintained.

The test room temperature is about 24 ℃ today.

Because the brewing process needs to detect the temperature measurement, the brewing time is Delay, and the whole temperature is on the low side.

When brewing smoothly; summarize the temperature of hand-brewed coffee as follows

1. Pour boiling water 100℃ into 1max 2 fine nozzle kettle, the water temperature is about 90 ℃, it is suitable for the warm cup action of filter cup, coffee pot and coffee cup, and the amount of steaming water that begins to brew, the water temperature will drop to about 90 ℃.

two。 When the small spout pot is added to eight minutes full during the steaming process, the boiling water temperature in the pot can be maintained at about 92 ℃ 94 min.

3. During the whole process of manual extraction, the water temperature of coffee liquid extracted in the filter cup can be maintained at 86 ℃ 88 min.

4. There is a good warm pot action after the coffee pot is extracted, the coffee temperature is about 75 Mel 78 ℃

5. Pour the coffee cup into the coffee cup at a temperature of about 72 ℃, and a slight hot mouth is the cup of delicious warm coffee you want.

Ps1. The temperature of boiling water in any Size stainless steel thin spout pot is the same, using the rising temperature of stainless steel at room temperature to absorb the temperature drop of boiling water; depending on the amount of boiling water poured in, if you pour the boiled water of 1 meter and 2 containers, the temperature will drop to 90 ℃ 92 ℃; if you pour 8% full container boiled water, the temperature will drop to 93Mak 95 Mak.

Ps2. In the past, it was customary to pour a pot with a lid into a full container to boil water, then each time it felt that the water temperature would be higher, especially if the steaming water temperature was too high, later it was changed to a non-spout pot (flower cup) or this thin-mouth pot, first half of the water was washed to the steaming procedure by hand, and then filled with eight minutes, then twice poured the pot about 350ml water just to brew 20g coffee powder 300ml coffee, so brewing is actually very smooth. Steam with 90 ℃ upper and lower water temperature and keep the water temperature at 92 ℃ 94 ℃ during brewing. The coffee filter cup will maintain the extraction temperature of 86 Mel 88 Mel.

Ps3. Delicious coffee is suitable for tasting from just brewing warm to normal temperature. It can explore the change of taste and flavor of coffee at each temperature. It is also a pleasure of tasting coffee.
