Electrolux EA120 semi-automatic coffee with a knob for 1 cup or 2 of the knob, a switch, a fine coffee powder, I just put the coffee powder in the handle, and then open up the knob on the switch, and then flow down 1 cups of coffee together, I program wrong? How does it taste so astringent?!!
Yes, that's right. Is it the first time you use it? It's the first time it works
Is the problem of water, and then the finer the grinding of coffee powder, the ingredients are more easily extracted, the more heavy and strong taste, but grinding through the rules, easy to extract too much, bitter ingredients, the loss of the original acidity. On the other hand, the coarser the degree of grinding, the lighter the taste of the coffee, and the proper degree of coarseness can well reflect the acidity of the coffee. In addition, the extraction also has strict requirements in time control. Generally, a cup of extraction time in 1 minutes, 30 seconds or so, two cups in 2 minutes to 2 minutes, 30 seconds or so, 3 cups in 3 minutes or so, not more than 3 minutes and 30 seconds.Leave this time limit, extraction time is too short, it is easy to cause lack of extraction, taste insipid, too long, it is easy to extract excessive, coffee taste more bitter and miscellaneous flavor components.
Is that what the instructions say?!!!! Geeze! Serious problems!Astringency is obviously the problem of excessive extraction!1, the coffee powder you put in the handle should not be too thin first, or it will be extracted too much!2, you put a handle of powder can only extract a concentrated amount of coffee, big handle is two of the amount, add up to no cup. After a full cup, it was clear that it was over extracted.It might be useful to buy some coffee books or find some information online.The semi automatic coffee machine or automatic coffee machine or, in general is the espresso machine, semi-automatic not only to your manual powder loading manual extraction, you should hand then you want to make espresso coffee, for example, the most common is the heating or heating water into American milk into a latte. Do not believe the so-called "how much powder, multiplied by how much time, how many cups of coffee out" argument, so that coffee has long been you die, you certainly do not like the taste of her corpse!
