Functions of wine glass
Appreciate the color of the wine through the state of the wine swirling in the glass, thereby judging the quality of the wine. Therefore, the wine glass must be made light, so that it will not fall into the hand; if it is thin, the color of the wine can be clearly seen. Different types of wine glasses have their own characteristics taking into account the needs of drinking. Generally speaking, the decisive factors that cause the wide variety of wine glasses include the opening design and the size of the cup belly (the difference in the thickness of the wine glass is not very large). Among them, the different design of the opening determines the flow direction of the wine body entrance. We know that the taste buds of the tongue have different sensitive areas. The tip of the tongue corresponds to the sweet taste, the inside of the tongue corresponds to the sour taste, the outside of the tongue corresponds to the salty taste, and the base of the tongue corresponds to the bitter taste. The shape of the cup and the size of the mouth determine the first point of contact with the taste buds at the entrance of the wine body, thereby affecting the taste of the wine. For example, in a cup with a small opening, when drinking, the head must be lowered. The first sensory area where the wine flows into the tongue is the tip of the tongue, which highlights the aroma and fruity sweetness of the wine.
