The role of glass wine bottle concave bottom

The main reasons for the bottom of the wine bottle are as follows:
1. The concave bottom of the glass wine bottle is to improve the impact force of the wine bottle. The reason is that the resistance of flat-bottomed wine bottles is poor, while the physical strength of wine bottles with bottoms is higher, which can greatly reduce the probability of collision damage.
2. A uniform base material is formed around the concave bottom to improve the stability of the bottle when it is upright.
3. The concave bottom can reduce the internal volume of the bottle and make the bottle look more atmospheric.

What is the function of the bottom of a glass wine bottle?
The first thing that is recognized about the existence of glass wine bottle grooves is its practical value. Its biggest function is to accumulate sediment in wine. This was crucial for winegrowers who did not have low-temperature crystallization technology for early wine production. Early winemaking technology was relatively backward. On the contrary, after the wine is brewed, you need to use a wooden mesh filter to filter out the residue and peel. So let the sink and tannin crystals sit in the grooves at the bottom of the bottle. Let the wine settle while the bottle is standing upright. The sediment settles into grooves at the bottom of the bottle to reduce impurities in fine wines. Generally speaking, the longer the wine is stored, the deeper the bumps will be.
The presence of grooves also makes it easier to secure the bottle during the aging process. On a second related note, the presence of the grooves also makes it easier to spin the bottle. Early wines required regular rolling (usually a roller inserted into the bottom of the bottle). The groove at the bottom of the bottle is rolled in a circle at 20-30 degrees 2-3 times a day to touch the fermentation of the wine (Western countries call it the wine that awakens the sleeping soul). Therefore, there is also a place to insert the roller in the groove.
