Therefore, through the guidance of the shape of the cup body, wine can flow into the appropriate taste area of the tongue (the tongue has four different taste areas, the tip of the tongue is most sensitive to sweet taste, the back of the tongue is most sensitive to bitter taste, and the inside and outside of the tongue are most sensitive to acid and salt respectively), thus determining the final presentation of wine structure and flavor.

A wine cup is used for drinking. The basic type is mostly straight or open, and the diameter of the mouth edge is nearly equal to the cup height. With the continuous expansion of demand market and export growth of China's wine cup (wine set) industry, China's wine cup (wine set) industry will usher in a new development opportunity.
