Basic knowledge of Coffee correct use of several household coffee utensils

Drip coffee machine, also known as American coffee machine. Its prototype is hand-filter coffee, but it makes hand-filter computerized and automated by manual work. The principle is to heat through an electric heating pipe, distill the water to the sprinkler, condense it into hot water, and drop it evenly on the coffee powder on the filter (funnel). After the coffee pot turns on the switch on the filter, the coffee flows into the coffee pot.

Hand-brewed coffee is one of the ancient ways of brewing coffee, and until now it is still a necessary method for many diners to drink high-quality coffee. The essence of this method is that water leaks naturally and coffee is extracted by coffee powder. In terms of taste, the drip coffee machine is a manual process of electrification, so the taste and taste can fully achieve the purpose of expressing the characteristics of coffee itself.

The drip coffee machine is also the most commonly used home coffee machine in China. according to the survey, about 60% of households use this coffee machine. This kind of coffee machine not only inherits the traditional hand-made drip coffee, but also can be brewed automatically by the machine. Therefore, convenience has become the key word of this kind of machine. In the way of drinking, it also does not need to comply with the rules, can enjoy the natural taste of coffee like tea, can be seasoned, enjoy the special softness produced by the mixture of coffee and milk, and can drink coffee as usual in large cups. Small cups can be drunk as if cherishing the size of time.

This brewed coffee needs the right concentration. Under the right concentration, the characteristics of all good coffee can be expressed. Therefore, a reasonable amount of coffee powder corresponding to the right amount of water is the key to ensure that the taste of coffee is not distorted. Recommended ratio of brewing gouache: 8g / 120ml (powder / water).

A common problem is the confusion between household coffee machines and commercial coffee machines. Some families mistakenly think that they can buy large capacity as much as possible, and how much they need to brew. In the family guidance, some families buy 12 cups or more, but most of them brew 2-3 cups in practice. The result is that the coffee is soaked for insufficient time, the extraction effect is not good, and the taste is light.

In fact, the most common drip coffee machines are marked with minimum and maximum brewing capacity. This is because the heating tube of the water heater of the drip coffee machine is fixed, and the power of the heating tube of the coffee machine of different sizes is different, and the larger the machine, the greater the power of the heating tube. Its function is that regardless of the size of the coffee machine, the maximum capacity of the water heater can be completely raised and evaporated in 2-3 minutes, which is the reasonable brewing time for soaking filtered coffee. It is only at this time that coffee extraction is ideal and tastes the best. More than this time, the coffee is overextracted, while the coffee is mixed and scorched; less than this time, the coffee is either insufficient in flavor, mellow, or tasteless at all.

Therefore, the family to buy drip coffee machine, should be based on the household regular use of coffee to determine the size, the minimum brewing volume is the reference index. In general, for a family of 2 to 3 people, it is more appropriate to buy the size of 4 to 6 cups; if you use it alone, the brewing volume of 2 to 4 cups is enough.

Recommendations:

1. Recognize and accept drip coffee is a kind of filtered coffee. The need to drink conveniently and casually is the purpose of buying this kind of coffee machine.

2. The capacity of the coffee machine is an important reference when choosing and purchasing the machine, and each brewing amount must be greater than the minimum reasonable brewing amount. When buying a machine, you should know at least how many cups of coffee you need to brew at a time.

3. Appropriate concentration. Gouache ratio: 8g / 120ml (powder / water)

4. Correct coffee powder granularity: medium and fine granularity. When you buy coffee beans, you'd better ask the coffee bean supplier for a medium and fine-grained powder sample for reference.
