Advantages and disadvantages of French filter kettle

What is more fatal is that as time goes by, fallacies spread. In coffee shops that only use eight grams of heart, on well-known coffee websites on the Internet, and even in the cooking tips dictated by some experts, rough grinding and long soaking have become a portrayal of French pressure. The cups of coffee made from this are either forcibly drunk or fed to the poor sink. Therefore, it has become a general consensus that such a simple instrument can only have such an effect. As a result, France was marked with congenital deficiencies.

So is French pressure really only used for making tea? The answer is no at all! In fact, if you want to choose the most practical coffee entry equipment, French pressure will not be at the top of the pack, but it must be among the top three. Its ease of control over time and the convenience of observation are unmatched by other brewing instruments.

Playing French pressure is the easiest time to control, the same situation of beans, grinding, different water temperature of different time has different effects. Generally speaking, the longer the time, the stronger the taste, but it is prone to bitterness, astringency and miscellaneous taste. However, when the five major factors of playing coffee change, the control time will have unexpected results: for example, deep-roasted beans will get great aroma and sweetness if the time is shorter, while light-roasted beans need a little more time to extract acid and aroma.

Observe the condition of beans, because French pressure is the easiest equipment to concentrate on the condition of beans. You can look at the amount of crema of coffee after contact with water, and the coffee suspended on the surface of the water slowly sinking, observing these phenomena can not only learn more about beans, but also have a better understanding of other equipment.

Of course, the French pressure is not perfect, the metal filter can not completely filter fine powder is one of the problems, so there is a French pressure needs rough grinding point of view, it is true that rough grinding can reduce the content of fine powder to a certain extent. But the price is that the particles get thicker and much of the content cannot be extracted. Based on this, there is a point of view that it is necessary to increase the extraction time to improve the extraction rate. However, the effective extraction temperature range of each kind of bean is very narrow, there is no heat preservation function of the French pressure, only tens of seconds is in the effective extraction. At the same time, as the fine powder can not be completely eliminated, after several minutes of soaking, they were thoroughly over-extracted, bitter, astringent and miscellaneous tastes gushed out one after another, so a cup of coffee that can only be used to entertain the sink was born.

Xiao he is to blame for the so-called success or failure. If we take advantage of the characteristic that the metal screen will let the fine powder pass through, our French pressure will become a professional coffee press filter pot, and all we need to achieve this step is a detailed metal screen (fineness is based on Hario's TH series filter press, if you can buy that kind of filter pot that can see the mesh clearly with the naked eye, please buy some good tea to make it) and an ordinary coffee mill: domestic Pegasus. Swiss-made solis166/167 and high-quality hand mill can be competent. The degree of grinding should be slightly thicker than spinning sugar, so that the degree of grinding is basically close to the limit of ordinary coffee grinding (another case for changing the machine), and then the ground coffee powder will be carefully sifted with the pleasant dry aroma. Do not pity the fine powder that floats away, it is a poisonous powder that destroys the quality of coffee, and you do not have to sift it for too long so as not to affect the freshness, of course, if you use fresh beans baked within 2 weeks. All efforts beyond this deadline are in vain. But at least you can get a cup of black liquid that is easier to enter than before.
