Friends who know something about wine should all know that the appropriate wine glasses for different wines are completely different. Generally speaking, wineglass manufacturers will specially make various red wine glasses, white wine glasses and champagne flute cups according to different types of wine and different requirements for oxidation and serving temperature. Choosing a suitable wine cup can improve the visual effect of wine as well as the wonderful degree of aroma and taste. What is the difference between a white wine cup and a red wine cup? 1, the various parts of the glass Each wine cup is made up of 3 parts, namely the cup body, the cup bean and the cup foot. The type of wine determines which type of glass should be used. Red wine glasses and white wine glasses usually have different cups and cups. When serving wine, be sure to grab the cup bean to avoid fingerprints on the cup body. When drinking wine, you can decide whether to hold the cup or the bean according to the specific temperature. 2. Red wine glasses During the brewing process of red wine, red grapes will be squeezed with skins. Some red grape varieties look red, but more varieties will show a blue hue. Since most grape pulp is cyan, skin pressing can add polyphenol and tannin to the wine, making the red wine show its proper color and structure. If red wine is exposed to the air for a long time, it will help eliminate the astringency of tannin and make the wine have soft and full flavor and aroma. Red wine glasses can make wine contact with more oxygen. They also have a wider cup mouth and a shorter and rounder cup body, which enables wine to contact the air more widely. Red grape wine glasses usually have longer cups to facilitate tasting to shake the wine before drinking and further oxidize it. The action of shaking the wine cup can release the aroma in the wine, so that the tasting can smell more complicated aroma. The sweet taste and aroma of red wine will be obvious in warmer environment, but if drinking red wine at higher temperature, the wine will give people an unpleasant feeling. When the red wine is moved out of the low temperature cellar, it can be sobered up for 20 minutes. You can also take the body of a red wine glass to increase the temperature of the wine. Red wine * serves between 10 and 15 degrees Celsius. 3. White Wine Cup White wine does not need to be oxidized like red wine. Since white wine does not have tannins in red wine, the taste of white wine will appear sweeter and lighter. This kind of flavor * can be enjoyed after cooling down. The temperature of about 7 degrees Celsius is just right. Lower temperature will reduce the aroma and taste of wine, therefore, the cup opening of white wine cup will be smaller and narrower to reduce the degree of wine contact with air. Since the chilled temperature of white wine is required, the glass needs a higher and thicker glass to be convenient for the tasting to hold. 4. Other aspects Observing the color and stability of red wine is an important aspect to increase tasting experience. As the "leg" of wine-this greasy drop can show the sugar and alcohol content in wine, and the quality and age of wine can also be seen from its color, red wine glasses seem to need more transparent glasses and crystal glasses to hold them.
