What is the function of wine bottle grooves?

Many wine bottles have grooves on the bottom, which vary in depth. So what is the function of the grooves?

The grooves allow the bottle to stand firmly upright. Because in the past, glass bottles were blown manually by mouth. The bottom of the bottle is recessed into the bottle body to allow the bottle to stand stably on the table. Modern technology has made it possible for the bottle to stand firmly even if the bottom is flat. However, for some aged wines, the grooves have the function of collecting wine dregs. When pouring the wine, the wine dregs can get stuck in the grooves, preventing them from spreading to the entire bottle under the impact of the wine at the bottom. .

The grooves will also prevent the wine bottle from exploding. The structure of the bottle with groove structure is very strong. The curve of the groove makes the bottom of the bottle as strong as the bottle wall. Some champagne bottles have very deep grooves.

The size of the groove is related to the volume of the bottle itself. Generally, a normal wine bottle can hold 750ML of wine. Therefore, in order to ensure a certain volume, if the bottle body is larger, the groove at the bottom of the bottle will be deeper.
