The three factors affecting brewing coffee are water temperature (Temperature), time (Time) and water flow (Turbulence). The water temperature, the soaking time and the strength of the stirring flow, like the thickness, will affect the extraction rate, and then affect the thickness of the coffee. Interestingly, 3T needs to be inversely proportional to the degree of roasting in order to make delicious coffee. The water temperature of brewing coffee should be related to the degree of roasting.

Let's introduce these three popular rating methods. One: the reason for the emergence of such a classification standard according to the altitude of the coffee producing area is mainly because of the high level.

In a sense, the grinder plays a more important role in the espresso machine than the coffee machine itself has always liked to say: what exactly is the coffee machine for? As mentioned earlier, the three main functions are extracting coffee, milking, and heating water. But today, due to talking about research,

At this point, you need to increase the amount of powder (to get more concentrated dose) to enhance the concentrated flavor of the milk coffee. On the contrary, pure black coffee or small-dose milk coffee need to reduce the amount of powder. Milk coffee in many boutique cafes, strong

2015-12-16 Coffee roasting techniques key points process medium hair raw basic chemical reactionWhen hot water is injected, the speed of filtration will be different, so the extraction time will also change. The difference in extraction time will lead to a difference in coffee flavor. The filtration speed varies with the area of the hole on the filter cup. The smaller the area is, the slower the filtration speed is. This type of filter cup will stay in the filter cup first because the injected hot water will first stay in the filter cup, and then filter at a certain speed, and the extraction will stop.

Some people do not like the gold cup theory, because the name seems to imply that as long as it meets this standard, it is "delicious coffee". In fact, I quite agree that coffee that is not in line with the golden cup theory is good, but it is a bit strange to say that we can ignore the golden cup theory at all. It may also be called "extract".

The main thermally reactive components are monosaccharides and sucrose, chlorogenic acid, displaced amino acids, and trigonelline amide. Both aravinone and calactose in polysaccharides are transferred, and basic sulfurization contains hydroxyamino acids.

The roaster I use is mainly based on direct fire baking, so I often encounter a lot of trouble in the early baking, after all, there are not many friends who use direct fire machine! The topic being studied recently is dehydration, or drying process, which is distributed throughout the roasting stage of coffee beans.

I will put my thoughts here first. For your reference and correction. According to the habit of many baristas, the amount of powder we set has far exceeded 14g (two portions). A friend asked me whether this is a problem of excessive extraction, or whether the current standard needs to be changed. At this point, you can talk about it.
