Why Are the Bottoms of Wine Bottles Curved Inwards?

The bottom of most, but not all, wine bottles is recessed rather than flat. This indentation Designed with an inward curve and some of them have faint serrations on their edges.

Alright, Why is the bottom of wine bottles recessed rather than flat?

This concave recess at the bottom of wine bottles is called “punt”.

In fact, not every wine bottle has a puncture at the bottom, and in those that do, a clear consensus has not yet been reached as to the purpose of this indentation, but of course there are a few opinions at this point. So much so that the existence of these punts It may even be based on a coincidence.

Namely, in the periods when wine bottles were shaped by blowing, a long and hollow glass called a pipe was used in glassmaking. After this glass is shaped by inflating a certain amount, it is then used to separate the glass from the blowing pipe. A metal rod called pontil was used.

The pontil placed on the bottom of the hot blown bottle usually left a mark at the point where it was separated from the glass, and this was called the pontil mark. At the end of this process, which leaves a protrusion at the bottom of the glass, Even though attempts were made to make the bottom of the bottles completely flat, This was probably not possible.

Thus, to ensure that the bottles stood upright and that there was no sharp glass at the bottom, the bottom of the bottle was pushed inwards, creating a punt.

Essentially, this meaningless indentation is for those who like to serve wine by holding the bottle from the bottom. It serves as a point for grasping by placing one’s thumb sees.

Also punt, bottles stacked end to end Allows. If bottles are stacked this way, they are less likely to be damaged or rolled over.

Again, one of the most common opinions is that this indentation in wine bottles is used in case of sediment formation in the wine. It prevents the sediment from spilling out when the wine is poured into the glass.

Essentially, whether a wine bottle has an indentation or not does not mean anything about the quality of that wine.

But since indented wine bottles are generally more expensive than flat ones, the presence of the punt an indication that the winemaker is spending more money on his bottle can be considered as.

The most important detail at this point is that these recesses greatly increase the resistance of the bottles. This provides a much greater surface area for the bottle to withstand the pressure of carbon dioxide gas, especially found in sparkling wines. In short, that recess that we cannot understand, It ensures the preservation of the wine’s foam.

According to a final opinion, since the indentations at the bottom of the bottles increase the surface area, the wine comes into contact with more ice and thus It allows the liquid inside to cool faster. Maybe it makes more sense to indent the bottoms of all drinks?
