Have you ever noticed that many glass bottles — especially wine or champagne bottles — have a concave bottom? Known as a “punt” or “kick-up,” this little detail is far from random and actually serves multiple clever purposes.
– 1. Enhanced Stability
The indented bottom improves the bottle’s balance, particularly on uneven surfaces, helping to prevent tipping.
– 2. Easier Cleaning
Originally, the concave shape helped sediment and impurities settle in the center, simplifying separation when pouring or serving the liquid.
– 3. Better Pressure Resistance
Especially important for bottles under pressure (like champagne or beer), the punt redistributes internal pressure, reducing the risk of explosion.
– 4. Premium Look and Feel
A concave bottom gives the bottle a more elegant and refined appearance, often associated with high-quality products.
– 5. Improved Serving Grip
The punt also allows sommeliers to insert their thumb into the indentation for a better grip and smoother pouring experience.
✅ In Summary:
The concave bottom is a smart mix of functionality, safety, and aesthetic. What looks like a simple glass detail is actually a well-engineered feature packed with advantages!
