A punt is the indentation found at the bottom of many wine bottles, particularly in sparkling wines and some higher-quality still wines. The reason for its inclusion is a combination of both tradition and function. Historically, glassblowers would create punts to help the bottle stand upright, since hand-blown bottles often had uneven bases. Today, it remains a feature in many wine bottles, particularly those used for Champagne and other sparkling wines.
From a functional standpoint, the punt strengthens the bottle. Sparkling wines require thicker bottles to withstand the high internal pressure created by the carbon dioxide, and the punt helps distribute that pressure evenly across the bottle. Additionally, the punt allows easier handling of the bottle for pouring, offering a place to rest your thumb while holding the bottle at an angle.
Some wine enthusiasts also associate a deeper punt with higher-quality wine, although this isn’t a strict rule. The design and depth of it vary depending on the wine producer’s preferences, and not all high-quality wines have a deep punt. The aesthetic of the bottle also plays a role in the inclusion of it, as it creates a classic, elegant look that enhances the presentation of the wine.
