The aroma of coffee

Aroma is olfactory, fragrance is taste, this is the difference between aroma and fragrance in feeling. Aroma is the emotional communication between coffee and people, which brings people more spiritual and emotional experience and enjoyment; aroma is the pleasure of coffee to the skin to meet people's instinctive desires. One is metaphysical, the other is metaphysical. They don't come from the same substance at all.

The taste of coffee is classified as four flavors and one fragrance, which reflects the Chinese people's understanding of coffee, which is a primary understanding.

Taste, in fact, is not a result, but the performance of the process in the result. This process includes the implication of the original substance of coffee, as well as the pursuit of this implication in baking. Fragrance and aroma are the different results of the two pursuits.

European baking and American baking are the result of the difference between aroma and aroma, resulting in two kinds of opposition. The fragrance composed of aroma makes people really experience the quality of life and the most intimate and gentle side of coffee; while the fragrance is a rough ravage needed by the hunger and thirst of human nature, although after being reconciled, it has some sentiment, but it is still a kind of wild invasion after rough teasing, resulting in the death of immortals, which makes people strive for it assiduously.

The aroma is caused by the oil in the coffee, which reflects a "charred" taste under the action of high temperature, which is the standard feeling by which most people judge the aroma of coffee. Because the oil has a kind of adhesion to the oral tissue in the mouth, so that this flavor can be retained in the mouth for a long time, thus getting the effect of "lips and teeth retaining fragrance". It also has a performance in the smell, but its smell does not constitute the most charming part of the coffee, it is just a little "murmur" in the charm of the coffee aroma. All other flavors are expressed in the smell, but again, they are not the main part of the charm of the aroma.
