What Is The Groove On The Bottom Of A Wine Bottle Used For?

With the development of production technology, mechanically blown and extruded glass bottles have gradually replaced artificially blown glass bottles. The bottom of the bottle is smoother and flatter than before, and the emergence of modern filtering technology and low-temperature crystallization technology has greatly improved the clarity of the wine. Technological progress allows people to safely use flat-bottomed bottles with lower production costs instead of heavy canopy-bottomed bottles.
Today, flat-bottomed bottles have been widely used in the packaging of various types of wines. Taking French wine as an example, in Bordeaux, more and more high-shouldered flat-bottomed wine bottles are used to store Cabernet Sauvignon, Merlot and Sauvignon Blanc wines. However, with the growing growth of the Chinese wine market, many wine merchants will still use canopy-bottomed bottles to expand their market share in order to cater to the public's misconception of wine, such as the deeper the groove at the bottom of the bottle, the better, and corks are better than screw caps.

Increase stability: The existence of the groove forms a triangle at the bottom of the bottle. The triangle is stable, so it can play a role in preventing falls. Moreover, wine bottles with grooves are more stable when placed upright and are not easy to tilt. Sedimentation of residue: The grooves at the bottom of the wine bottle and the gaps created by the edges of the wine bottle can precipitate the residue of the wine, so that the residue is not easily poured out when pouring the wine. Wine bottles are cylindrical and are prone to rolling during storage or transportation. If you store or transport wine in large quantities, you can consider laying the bottles flat and then using the grooves of the previous bottle to connect the mouth of the next bottle. This not only prevents rolling, but is also very stable and saves space.

Some wines will form some sediments after aging for a long time. These sediments are harmless, but if you drink them, they will definitely affect the tasting experience. However, with the design of the concave bottom of the bottle, when decanting, the sediment can slowly slide from the bottom of the groove to the bottle shoulder, and the sediment is not so easy to pour out.
