High-end coffee brand illy holds espresso tasting

Coffee contains caffeine, which excites the sympathetic nerves after entering the body, thus eliminating drowsiness, improving blood circulation, and the body also feels warm and does not feel tired, so it has a "refreshing" effect.

However, when the sympathetic nerve is stimulated and excited, it has a negative effect on appetite, that is, appetite will be reduced, so drinking coffee before a meal will not want to eat. In addition, due to the stimulation of the stomach and the increase of gastric juice secretion, stimulating the empty stomach is disadvantageous to patients such as gastric ulcers. This can be said to be the negative effect of coffee. But drinking after a meal is helpful to digestion because the secretion of gastric juice will increase. Therefore, there is absolutely no problem with drinking after a meal.

In addition, some people think that adding a little milk to drink can ease its irritating effect, but how much of a small amount of milk can neutralize caffeine, unless half milk and half coffee, mixed with coffee milk or milk coffee, may have some effect. For example, coffee and milk for breakfast, because there is more milk than coffee, although it is drunk on an empty stomach, it still has the effect of relieving gastric juice.

Ideally, drink after a meal, which is beneficial but harmless. One of the benefits is to prevent the onset of allergies. As a result of allergic parasympathetic nerve excitation caused by asthma or allergic rhinitis, if it can promote sympathetic nerve excitement, inhibit parasympathetic nerve, it will help to prevent the attack. Especially serious allergic patients, some mild incentives can cause physical discomfort, coupled with psychological fear of allergies, often out of control. Therefore, it is recommended to make use of the advantages of caffeine to drink a cup of coffee in advance when allergies and asthma are about to occur (the patient feels it), which is quite preventive. In addition to the excitatory effects of caffeine, patients who have "already had coffee" on sense of security are less likely to attack.

Of course, as the saying goes, "going too far is not as good as it is". No matter how good it is, we have to "enough is enough". Otherwise, regardless of drinking before and after meals, excessive caffeine will lead to hyperpalpitation (the heart beats violently), and even side effects such as trance, unstable walking center and so on.

In principle, it is appropriate to drink two to three cups of coffee a day. If you drink four or five cups, most people will feel sick, so be careful. In principle, no more than three cups a day is best for any kind of irritating drink.

Italian Coffee University (China)

Let's digitize the production process of espresso. A cup of high-quality espresso requires 6-7 grams (about 50) of Arabica coffee beans, ground into a fine powder about 1 micron in diameter, flow through water at a temperature of 90 degrees Celsius, about 30 cubic centimeters (30cc) at 9 atmospheric pressure, and extract about 30cc coffee liquid in no more than 30 seconds.

The dark liquid, covered with a layer of brown grease (crema), contains 1500 chemicals (800volatile and 700soluble), forming an extremely complex and subtle fragrance. Like wine, drinking espresso coffee is a complex sensory feast that requires "seeing-smelling-drinking" steps and attentively feeling the slightest changes. Before the entrance, first observe the appearance and color of the coffee, and then smell its aroma, and finally taste the consistency of the juice and the entrance throat rhyme. Espresso must be finished as soon as possible after production, because many ingredients will decompose due to oxidation or lower temperature, thus losing the original flavor. Of the more than 1000 aromas that can be identified, roasting aromas from the conversion of sugar in coffee beans, cocoa with a hint of vanilla, flower-like aromas and sweetness similar to fresh fruit are the most easily identified.

Espresso is the perfect coffee drink. In terms of quality, espresso has a thicker texture than water-drop coffee, and contains higher dissolved matter per unit volume than water-drop coffee, because of the short-time and high-pressure brewing process, the fragrant oil is also more abundant than other brewing equipment. At the same time, the short quenching time makes espresso contain less caffeine. Both of these make espresso a favorite of countless experienced coffee lovers.
