Everyone knows that bottles of sparkling wine and champagne (but also wine bottles) have punts in the bottom, but few know what it is for. Some might assume that it is for a more ergonomic handle, but it is actually about the pressure of the liquid inside. In fact, the "bell" shape guarantees greater mechanical resistance to the pressure of the gases contained in wine and sparkling wine.
