Dips in Bottles
Have you ever paid attention to a pretty noticeable dip at the bottom of the wine bottle? The dip is more apparent when a bottle is empty, looks a bit funny and makes us wonder about its purpose. Well, it is made for a few reasons, and the first of them is that the bottle becomes a bit more stable and will not flop over because of the wind if you take it with you on a family outing. Just for your guidance, those who make bottles call this dip a kick-up or a punt, and they always check that all wine bottles are made this way.
It is especially important for bottles with sparkling wines, which should be thick, tough and able to hold up a high pressure. In addition, a punt helps steam to be better distributed within a bottle when you clean it, thus assuring spotless insides.
