Peculiarity in wine bottles
If you are a wine lover, you might find this one more than interesting. Because if you look at the wine bottles, you can notice how at the bottom the liquid passes from one side to the other, this part is known as the punt. Specifically designed to provide more strength to the bottle and prevent it from easily falling.
Another known function of this is that these bottles can also carry sparkling wines, champagne and other similar liquors.
