Qianjie-Hand brewed coffee history, grinding degree introduction

Martin coffee pot is the earliest filter and container (or stew) separation, meaning coffee powder extraction from the infusion of the beginning of the development of filtration. For hundreds of years, filter shapes, styles and materials have been constantly updated. More specialized flannel handles appeared, as did ceramic or metal, resin filter cups and filter paper combinations. It can even be said that today's popular coffee ear bag style (invented in Japan), there are Martin coffee pot figure. With more and more extraction research and scientific and technological progress, people realize that the different proportion in the filtration and soaking process will have a great impact on the taste, so that the conditions for brewing coffee become more and more detailed, the production of hand-made pots becomes refined, and the hand-made technology begins to gradually form.

A lot of small partners who consult us for hand-brewed coffee will have a lot of equipment problems. We will introduce some of the equipment I commonly use to you. We suggest that you actually use it in our classroom to buy it. This match can save a lot of money! Necessary equipment: hand washing pot, electronic scale, filter cup, filter material, coffee cup, grinding equipment;

Getting Started with Handwashing

Coffee brewing first of all we have to make sure that the water powder ratio, water can not be too much or too little, grinding recommended cup grinding, each grinding equipment will have a recommended grinding, determine the water temperature and brewing total time. Water temperature: 93℃, 18g powder with 288ml water, total time is 2 minutes

We all know that there are many factors affecting hand brewing, and grinding degree is also one of them. Grinding degree generally refers to the size of coffee particles, which directly affects the contact time between coffee and water.

In the case of the same other parameters, the finer the particle, the higher the extraction rate, the finer the coffee powder, the larger the contact area with water, and the higher the concentration of dissolved coffee. Conversely, the coarser the coffee is ground, the less the contact area with water, and the lower the concentration of coffee extracted.

Before someone asked Xiaobian, then I want to extract more substances, more coffee flavor, then I can grind the coffee powder finer. It is not impossible, but you should know that if the coffee powder is ground more finely, the more fine powder, it is easy to block the filter paper hole, once the water is difficult to pass through the filter paper, the speed of coffee extraction will slow down, and the extraction time will be lengthened, which will lead to bitter and miscellaneous coffee extraction, difficult to swallow. Of course, if you are a hand punch person and know how to use fine powder, then say something else ~

However, there is a device that must be relatively fine powder, that is, Italian machine extraction concentrated, Italian concentrated extraction is a short time through high pressure extraction of coffee, water quickly through the coffee powder, thus extracting the aroma and taste of coffee.

Knowledge point: hand-brewed coffee is made by hand with a single variety of coffee beans from a single origin, and those who are particular even roast and grind their own beans.

In brief: Qianjie is a coffee research center, happy to share knowledge about coffee with everyone, we share it without reservation only to let more friends fall in love with coffee, and there will be 3 low discount coffee activities every month, because Qianjie wants to let more friends drink the best coffee at the lowest price, which is also the purpose of Qianjie for 6 years!
