Why do wine bottles have a dent?
The large indent in the base of wine bottles is known as a punt. It is intended to strengthen the bottle and not to give the impression that the bottle contains more liquid than it really does.
The dimple or punt (indentation) on the bottom of a Bordeaux style wine bottle. Some say that the punt serves to catch sediment from the wine, as it precipitates out of solution. The ring at the bottom collects the sediment which forms into a hard circle that does not as easily dislodge and enter back into the wine.
Why are some wine bottles heavier than others?
Heavier bottles typically use more glass, which makes the boxes they come in wider as well. A pallet of wine typically holds 56 cases. A box that holds ultra-heavy wine bottles are just wide enough to permit 50 to 52 cases on a pallet. So the wines are more expensive to ship.
Why are wines stored horizontally?
A horizontal bottle keeps the cork moist, so it doesn’t dry out and shrink. The air gap in a wine bottle has almost 100 per cent humidity, so the cork will never dry out as long as there is wine in the bottle. …
In fact historically, the dents (or punts as they’re officially known as) were put in the bottom of bottles to help them stand up straight and prevent them from breaking. However since glass bottles are now made by machine, and are a lot more structurally sound, they’re unlikely to need the indentation.
