Brewing coffee has a precise requirement for water temperature, that is, the water temperature should be 92 ~ 96 degrees. If the water temperature is too high, the coffee will be a cup of scorched bitter water, because the temperature above 96 degrees can destroy the oil in the coffee and taste bitter and astringent.
1 if you are using the Delong coffee machine in the company, it is recommended not to use coffee powder, because if you add no more than 2 tablespoons of coffee powder at a time, it will damage the machine, and adding only one spoonful of coffee powder at a time is too slow for the unit to make coffee; in addition, the taste of coffee powder is not as fresh as coffee made from coffee beans.
2 if the coffee machine is not expected to be used for a long time, it is recommended to use all the coffee beans in the bean warehouse, otherwise it is easy to cause clogging of the coffee machine grinder. The coffee barn should be kept dry. Special attention should be paid to the wet season and some areas.
3 when the coffee machine is working, it is necessary to keep the water tank with enough water and can not be dry-boiled without water (users of the Delong coffee machine need not worry too much, because the water tank of the Delong coffee machine has the lowest water level protection function, which will prompt the alarm to add water in time.), do not draw out the water tank, otherwise it will damage the machine. However, the water used in the coffee machine requires the attention of consumers, and pure water is recommended.
