How many ways are there to brew coffee at home? which one is more suitable for brewing coffee?

You can buy coffee at home. If you want to make coffee by hand, you can buy a coffee pot. The temperature of the coffee pot is about 95 degrees Celsius when boiling water is poured into the cold hand pot. At this time, you can grind the beans (I will grind the beans by hand or grind them first. As DIMLAU said, 95 degrees starts steaming, and when flushing, the kettle can start to flush at about 90 degrees. Basically, the water temperature is always in the right state, and you don't have to worry about it without a thermometer.

Powder-water ratio: for those who are too lazy to understand the golden cup, please read the boldface directly. Citing the rule of the fool's version of the golden cup (temporarily based on the American version of the gold cup, based on the average concentration and average extraction rate of American black coffee drinkers' favorite range of nearly 10,000 random samples), the data is 1.15% to 1.35%, and the extraction rate is 18% to 22%. Of course, the fool version should be streamlined, and we all take the midpoint, that is, our goal is 1.25% concentration and 20% extraction rate. So what can we control? Powder-water ratio ~ 1:16 is recommended (1g coffee powder corresponds to 16ml water). Under this powder-water ratio, the extraction rate is 20%, then the concentration is exactly 1.25%. Because it is the midpoint of the range, the fault tolerance rate is the highest.

Steaming: the first part of steaming is actually strong enough for the water to come into full contact with the coffee powder, exhaust the gas, and infiltrate the coffee powder to facilitate subsequent extraction. So there's no stick? There is a Tilafa, but you can't do it? You look good enough to wet the coffee powder. Japanese brewing will be steamed to only one drop, or not dripping and fully infiltrating, it is useless to tell you, scientifically speaking, it is just enough contact with powder and water.

Segmented extraction: in fact, it is water injection. In the video, the main variables that mainly rely on immersion extraction are grinding degree and soaking time. Water injection only needs to pay attention to the fact that coffee powder is soaked, and whether the circle is round or not. Whether the water flow is fine or not can be ignored. So we only need to control the total extraction time at two and a half to three minutes, the general extraction rate will not be too biased, during which time it will be horse step water injection or handstand water injection.

The pit of the equipment

What can be saved the most? Share the pot... A better sharing pot is basically more than 100 yuan, so just get a cup. The filter cup of HARIO V60 resin is about 30, and the filter paper is 20 to 100 pieces. There is no pressure to get a small pot to open the student party directly.

What is the deepest hole? Bean grinder, Xu Yingjie in the answer is a mixed forum, there are all kinds of divine comments. PORLEX is an Italian mill. Originally, family espresso is not very popular in Japan. A Japanese manufacturer can't buy a hand mill to use it. Today, we can still see that the PORLEX factory is a commercial miracle. I also specially went to the Japanese PORLEX official website to check, but they didn't say, ah, where did the news come from?
