There are three main types; Bordeaux wine glasses, Burgundy wine glasses, universal wine glasses. Bordeaux glass is relatively high, and the mouth of the glass is narrower than that of Burgundy glass, so as to retain the fragrance of Bordeaux red wine in the glass. The capacity varies from 12 to 18 oz. These two kinds of cups named after grape producing areas can indeed be said to be tailor-made for grape varieties in different producing areas-Bordeaux cups are more suitable for tasting wines from Bordeaux producing areas, whether it is rich and heavy Cabernet Sauvignon or Merlot with soft tannins and low acidity, they can perform well; When tasting Pinot Noir with high acidity in Burgundy, the Burgundy Cup is even better. Because different parts of the tongue are sensitive to taste in different degrees-the tip of the tongue is the most sensitive to sweetness, the root of the tongue is the most sensitive to bitterness, and the inner and outer sides of the tongue are sensitive to acid and salty respectively. The design of wine glasses is based on such a human body structure. The different order of wine tongue wrapping can balance the sweetness of fruit and the sourness of tannin, making the taste smoother.
