What if the water temperature of hand-made coffee drops too fast? Can you drink the caking solution of coffee powder?

Just the day before yesterday, Guangzhou changed from summer to winter. This is supposed to be nothing, but the cold in Guangzhou is a wet and cold magic attack, and the opponent also makes penetrating damage when making coffee. So much so that making coffee in winter feels a little different. Qianjie Coffee will take an inventory of the common coffee brewing problems in winter.

Coffee powder caking when grinding coffee powder is not uncommon, mainly due to static electricity, wet reasons, some of the finer powder will hold together. This kind of situation will be more in winter, too much for people to scratch.

For example, some bean grinders are equipped with electrostatic rods on the outlet, but the actual effect is better than nothing. The caked coffee powder that falls is relatively easy to solve. The solution in the front street is to use a small spoon or needle to break up the caked coffee powder directly. Similarly, some coffee powder will stubbornly cling to the powder cup. We can still use this method to break up the coffee powder. And some coffee powder is directly glued to the mouth of the powder, which is what we often call "eating powder", such as precision grinding of 15 grams of coffee powder, but because the bean grinder eats the powder, the actual amount of flour is less than 15 grams. In the face of this situation, Qianjie gives you two solutions. The first is to pre-add 0.5-1 grams of coffee beans (depending on the degree of flour eaten by the bean grinder). For example, if the target amount of powder is 15 grams, then 15.5 grams of coffee beans can be ground, of course, this method seems wasteful in the long run.

The second way to stick powder very easily in winter is to buy a "leather tiger" (dust ball) online, which is less than 10 yuan. after grinding the beans, don't move the powder cup, put the leather tiger on the powder mouth and blow it, and the coffee powder stuck inside will come down. Very convenient.

There are rumors on the Internet that the solution to electrostatic caking can only be solved by dropping a drop of water on the beans that want to grind coffee beans. Qianjie is not recommended to do this, we assume that this method is effective, but it is difficult to control the amount of water drop, a little more inadvertently, the heat of the blade can not evaporate these moisture, the mixture of water and coffee oil will cause a devastating blow to the knife head, the loss outweighs the gain. A more obvious feature of water cooling fast in winter coffee making is that the water temperature drops very quickly, whether it is the water in the kettle or the filter cup. As long as the water loses its heating source, it begins to lose its temperature, and even if it is put in a thermos, it will still cool down, but the process will become very slow. In winter, due to the decrease in room temperature (the indoor temperature in the south is lower than outside), the whole cooling rate is much faster than in summer. For example, when brewing coffee at 91 degrees Celsius in summer, the temperature of the pot is still 88 degrees Celsius, while in winter, after brewing at 91 degrees Celsius, it is only less than 85 degrees Celsius. Even if the kettle is so warm, it is conservatively expected that the temperature of the whole extraction will drop by 1-2 degrees Celsius with the filter cup continuously exposed to the air.

Therefore, in order to deal with this situation, Qianjie suggests that if it is not a friend who uses a temperature control pot, first pour a small amount of hot water to preheat the kettle, and then pour more hot water into the pot than usual when pouring hot water into the pot. Enough hot water can keep the hot water in your hand-flushing pot against the cold room temperature and keep the water warm.

When cooking, the water temperature is 2 degrees Celsius higher than the daily temperature, so that the water temperature can be maintained during subsequent brewing. For example, the usual brewing of a coffee bean is used to use a water temperature of 90 degrees Celsius, then in a relatively cold environment, you can use a water temperature of 92 degrees Celsius to brew, which can better restore the normal taste. As for the friends who use the temperature control pot, they can put it back into the heating base at the interval of water injection to keep warm.
