Why do wine bottles have punts?

Pick up your latest wine purchase and examine the bottle. Besides a long, elegant neck, a corked (or screw-capped) top, and an eye-catching label, what else do you spot? Hint: check the bottom of your bottle. If you answered a “dimple,” then you just singled out one of the most mysterious features of the wine bottle, the punt.

Though not every wine has a punt in it, many do, and the reason behind the little indent isn’t clear. In fact, there’s no clear consensus as to why the punt is there, but there are plenty of fascinating theories. We singled out the ten that seem most plausible (or interesting) to us. You be the wine expert: tell us which one you find most likely.

1. The Punt Makes It Easier To Hold A Wine Bottle.

If you grab your wine bottle from the bottom, it’s no surprise that the punt is present, acting as a spot to place your thumb while the rest of your fingers grab the base of the bottle.

2. The Punt Allows The Bottle To Stand Upright

Glassblowers used to create punts to push the seam of a bottle up, allowing the bottle to stand upright while preventing glass at the bottom of the bottle from sticking out and cutting people.

3. Punts Used To Be An Indication That A Wine Was Well Made

However, today it seems that the existence of a punt and the quality of a wine have little to do with one another.

4. Punts Create An Optical Illusion That A Wine Bottle Is Bigger Than It Actually Is

Need we say more? If you’re comparing two 750 ml bottles, and one looks like it’s holding more juice, your eyes can often deceive your logic.

5. Punts Catch Sediment

Some posit that the angle of a punt lets sediment collect in a tight area near the base, stopping the sediment from blending back into the wine as it’s being poured.

6. Punts Make Your Wine Chill Quicker

A punt at the bottom of a bottle increases surface area, allowing more ice to come into contact with it and thus chilling the liquid inside quicker. Maybe we should indent our beer bottles too?

7. According To Folklore, A Punt Prevented A Bottle From Being Refilled

One tale states that taverns had a vertical steel pin in their bars. When a bottle of wine was consumed, the bottom of it would be punctured with the pins, ensuring that the bottle would not be refilled. We have to note that while this story is certainly colorful, it doesn’t explain why full bottles of wine contain punts.

8. Punts Make The Bottle Easier To Clean Before You Fill It With Wine

Think of it this way: it’s often difficult to clean a tall glass evenly. Perhaps this is what glassblowers had in mind when making the punt. When you shoot water into a wine bottle that has a punt, the water is spread more evenly throughout the bottom of the bottle.

9. Punts Make The Bottle More Resistant To High Pressure

And when they’re more resistant to high pressure, they can better hold sparkling wines like Champagne and Prosecco. We can all thank punts on New Year’s.

10. Punts Allow Bottles To Be More Easily Organized

Punts allow for more ease when it comes to stacking wine. If you’re a daily VinePair reader, we already know you’re getting excited about this organizational tip.
