The drinker concentrates on his glass and prepares to enjoy all the pleasures that wine can offer him.

In first place, there is the visual pleasure. For this, he will tilt his glass against the light so as to appreciate its colors and tints: its variations. So as not to deprive good wine enthusiasts of such a feast of color, God ignored the many pleadings of drinkers who begged him that wine be colorless and water red, so that the innkeepers could not baptize the wine.

Following, there is the scent; for which the enthusiast, taking the glass by its stem, will turn it from right to left, so as to increase the "bouquet" and study it attentively and with pleasure, trying to individualize each one of the various scents that he discerns.
Lastly, the greatest satisfaction: that of taste, which is comprised of three instances: the initial flavor, the secondary flavor and the final flavor.

To attain this, it is necessary to swirl the wine around your mouth and then, place it under your tongue and inhale. In this way all the taste buds come into play and all the flavors of the wine appear. The reason for all of these maneuvers, which usually lead to funny situations, is that every region of the mouth has a specific characteristic for sensing a given flavor. For instance, the tip of the tongue perceives sweetness; its sides, acidity; and the back, sourness. In that order the brain receives those sensations. This is why wine-tasting requires time and concentration.

Thus we come to the supreme moment: giving an opinion. Summarize all the sensations of color, perfume and taste and formulate a comprehensive and final evaluation of the wine.

The senses that participate have an extraordinary memory, and with time, the careful drinker can establish comparisons with past experiences and individualize colors, scents and tastes, qualifying them. To express such an opinion, there exists a special vocabulary  which can be found at the end of this treatise.

We now face an educated drinker.
