Many people are still unaware of the reason why the bottom of bottles is concave.

The  hollow base  also plays a key role in the strength of champagne bottles. Sparkling wine generates significant internal pressure, which can be up to  six times that of a car tire  !

A flat base wouldn’t withstand this force and would risk breaking under the pressure. The  punt ‘s hollow  distributes the tension more evenly, ensuring greater strength. This is why champagnes and other sparkling wines proudly retain  this characteristic  !

A multifaceted detail

Far from being a mere aesthetic whim, the  hollow bottom  of wine bottles is the result of centuries of ingenuity and adaptation. Whether for transportation, filtration, manufacturing, or safety, every aspect of this distinctive feature has found its place in the history of wine.

The next time you hold a bottle, you will know that  this hollow is not there by chance , but that it hides a whole world of secrets and traditions!
