The main purpose of a large glass is to smell the fragrance. Red wine is a low-alcohol wine with low volatility, so it needs a large glass space to release the aroma. Then, the rim of the glass is closed than the belly, so that the aroma can gather around the rim. The big cup, liquor and air contact surface is big, it does have a part of the effect of sober up, but this is not the main function of the big cup body. And I personally don't like to wake up from a glass. Except for a few very strong wines, most wines are extremely easy to wake up from with a glass of more than 500ml. Of course, the bigger the cup is not the better, according to the specific type of wine to choose. If you really want to be fastidious, it can't be done without buying twenty or thirty cups. Riedel knows a lot about this, so let's take Riedel's wine glass as an example. Some people say, "It doesn't matter what glass you drink from." I'm sure the person who says that is not a fastidious alcoholic. With different cups to drink mineral water will also have a different taste, let alone wine? Different kinds of wine are produced all over the world, and each region has its own unique glass, which is not only the result of tradition, but also the result of years of experience. A glass of a particular shape is often the best expression of a particular wine. Let's just talk about wine glasses today. Let's start with the aperitif, the general dinner wine to drink sparkling or champagne, sparkling wine is often used in a long glass, so that the bubble will last longer, drinking people can see the bubble slowly rise more beautiful. Because the mouth is narrow, the bubbles are more concentrated on the tongue, which makes the wine taste more lively and fresh.
