Last Updated: 2024/09/20, Why do you need the same amount of powder every time you make coffee? Is the espresso machine extracting powder and the water temperature low? Is the grinding degree of powder appropriate? Is the weight sufficient? Does the pump pressure match the amount and grind of coffee powder? Is the coffee ground evenly pressed during preparation? As long as one of these factors is not suitable, it will lead to sour coffee taste, and these factors

And is the water temperature on the low side? Is the grinding degree suitable? Is the weight sufficient? Does the working pump pressure of the coffee machine match the amount of coffee powder and the degree of grinding? Did the subject press the coffee powder evenly during production? As long as one of these factors is inappropriate, it will lead to the sour taste of coffee, and these factors affect each other, not independent factors.

This part of the soluble matter comes from the amount of coffee powder. So, we can get the extraction rate (extraction yield).

EY= TDS/DOSE is the gram weight of the soluble matter divided by the amount of powder used, and we know the percentage of how much has been extracted. In most cases, whether it is Italian concentrated coffee or hand-brewed coffee, the reasonable extraction rate is 18-21%.

I went through a little review. Now, starting with the amount of powder as the core, we will see how the amount of powder affects the flavor of coffee. Before that, let's take the high-end Mazzer Robur electric grinder in the market as an example. In my previous diary, if there is no powder, there can be a difference of about 2.3g between the minimum powder and the maximum powder. Let's just take this as an example, 2.3g, there seems to be only a "10%" difference in powder quantity, how different we will be in production.

Drink coffee in moderation and not in too high concentration. Generally speaking, we should not drink more than 50 grams of coffee every day. Many friends like to add some milk when drinking coffee, in fact, it is not appropriate to do so. You'd better not mix coffee with milk. If you really need to add something to drink, our advice is to use plant fat powder, which is commonly referred to as coffee companion or condensed milk instead. Why? This is because milk is very rich in minerals, especially calcium. Drinking milk is the best source of calcium supplement. However, when calcium and coffee are combined, caffeine, the main ingredient of coffee, absorbs minerals and calcium in milk.
