As we have always advocated, there are indeed many factors that need to be controlled if you want to make good coffee. But what we should really know is how to make good coffee, not a bunch of expensive equipment. Or, what is the difference between expensive equipment and ordinary inexpensive equipment?

Basic principle Formula of Coffee extraction

No nonsense, the most important formula for making coffee is below.

Concentration 1.6% = coffee powder 100g x extraction rate 20% / extraction amount (water, milk … Etc) 1250ml

In the above formula, there are two things that can be decided before making coffee, that is, coffee powder and water. And about the concentration, the only thing is the proportion of coffee in the water.

Coffee gold cup standard

In fact, Europe and the United States have their own boutique coffee standards, this has been sorted out of the proposed unit, called TDS (Total dissolved solids), the boutique coffee organizations of various countries recommended the TDS range as follows.

Us SCAA 1.15% Muay 1.35%

European SCAE 1.2%-1.45%

Norway NCA 1.3%-1.55%

In other words, if we want to make a good cup of coffee, we already have a good compass, and the rest is the extraction rate. The extraction rate is actually a very special place. If the coffee is extracted too much, it will often have some strange smell. I would suggest that the extraction rate should be controlled at about 20%, which is more acceptable to the public.

Coffee extraction rate?

This is the time for all kinds of coffee to make their debut in different ways, because the extraction rate is mainly how water interacts with coffee. It involves time, temperature, powder thickness and so on. Some good equipment can grind the coffee evenly, or if you use follicles, you can use the speed and height of water injection to control the time of water in the coffee powder, and so on. A coffee pot with a thin outlet does help at this time, because the weaker the water column, the more time the water spends in the coffee room and absorbs more coffee precipitates.

The most important coffee equipment?

I consider myself a theoretical pragmatist and am not obsessed with equipment or technology. for me, no matter how long it is, no matter how slow it is, the fragrance I want to achieve may not be as good as French bubbling for four minutes. If you want to invest in coffee brewing technology, I think the most important thing is an electronic scale and coffee concentration meter. Everyone knows what the electronic scale is. But to make sure you must have a coffee concentration meter, you can digitize the above formula.

The concentration of this ATAGO will cost me more than 10, 000 yuan to buy from an agent.

In this article, I will not talk about how to soak in various brewing methods, but only talk about the most important core formula. after all, there is no limit to equipment and technology, but the numbers can clearly tell you the direction. As long as you have an electronic scale and a coffee concentration meter, like a map and compass, it's hard to get lost in the world of making coffee.

▲ has this coffee concentration meter, which not only keeps your coffee brewed at a stable level, but also controls your daily intake of caffeine, which is a good helper for coffee drinkers.

This coffee concentration detector has three types of machines, one is to detect the coffee concentration, and the other is to detect the sugar concentration and the comprehensive type. If you want to have more functions, you can choose the comprehensive type to detect the coffee concentration and sugar content, not only to test the coffee, but also to use it in more places when cooking. Whether you are a professional barista or a player, you can use him to control the concentration of your coffee and improve your coffee brewing skills, basically by putting a drop of brewed coffee on it, pressing the test, and, of course, many other details.

▲ also has many detailed functions and settings, and the power supply is mainly No. 4 battery.
