Coffee knowledge must know a little common sense of brewing coffee
Some people say that, in fact, only 50% of each cup of coffee is made of coffee beans and sugar, and the other 50% is a complex thing called feeling.
Some friends will think that no matter in any way to brew coffee, the coffee powder that has been brewed once will have to be discarded, which will feel very wasteful. Especially for some coffee that is more expensive, you have to brew the coffee powder many times before you feel it is worth it.
It is important to know that from the time the coffee powder comes into contact with hot water, the taste of the coffee begins to be extracted until the coffee powder is completely soaked and finally to drink is a process.
Coffee in direct contact with hot water, it can be said that 95% of the coffee essence has been extracted, and if you use the brewed coffee powder to brew another cup of coffee, the taste of that cup of coffee may be light and thin coffee water, or even tasteless.
In fact, the amount of coffee powder used to make a cup of coffee ranges from 7 grams to 10 grams. Because of the different tastes, most of the retail packaging on the market is 200 grams, which can already brew 20-28 cups of coffee, and the cost can be regarded as very low. As far as I am concerned, coffee is a kind of enjoyable drink and fun, and it should not make the body suffer unnecessary torture and feel unpleasant.
In addition, some friends will heat the coffee in the microwave oven when it is cold or not hot enough, because after reheating, the aroma of the coffee will be completely lost, and the coffee will produce chemical changes that damage the taste and turn sour. If you can't drink freshly brewed coffee in real time for some reason, use an thermos or something called "vacuum pot vacuumairpot".
