wine bottlesYou may have not noticed it before. You may not have even have cared why it is there. But if ever you do take a closer look at most wine bottles, you might have seen that hollow indentation on the base of the wine bottle that seems to be pushed inward. That hollow indentation is called the punt and it provides some of the interesting parts that the wine bottle have come to be associated with.

Why do wine bottles really have punts?

Once you have looked closer into any ordinary wine bottle, such a question may have cropped up into your mind, even for flimsy second. There are many answers to such a simple question that people have come to believe brought about this unique quality in every wine bottle.

Bring together sediments

One theory for punts in wine bottles is that they help to bring together the sediments that come with older wines so that a lesser amount comes out when the wine is being poured out.

Help stack wine bottle

Another theory states that the punts were used to help stack the wine bottles, especially the ones used for Champagne, at a downward angle to facilitate with riddling or slightly turning the bottle at certain period in order to move the sediments nearer to the cork for later removal.

Give more strength

One of these practical reasons is that punts seem to give bottles more strength. The punts at the base of wine bottles seem to give them more structural integrity and able to handle a bit more pressure as totally flat based bottles. A possible example that will show this is when one tries to break a wine bottle. Most bottles will usually break at the sides or at the neck, but never at the punt.

Provide more balance

Another practical explanation for the punt is that it was created to provide more balance. Older hand blown wine bottles may have a base that can protrude outward at the base due to the pressure of the air inside as the glass is being formed.

If left on its own as the wine bottle dries, this might make the base take a rounder shape that may make the bottle more prone to tipping over and falling on its side. Glass blowers may have noticed this and try to push back the base in order to form that hollow indentation in order to give the base of wine bottles have better balance.

Wine making process

One possible reason for the punts in wine bottles is that it has become part of the process of making the wine bottles. A newly blown wine bottle may be placed on a rod in order to cool that makes the indentation at the base. It might also be created as the bottle is being spun while being blown and formed, creating that hollow indentation.
