Why Champagne Bottles Have Deep Punt Bottoms 🍾

Most people think the deep indentation at the bottom of a wine bottle (called a “punt”) is just for looks — but historically it actually helped strengthen bottles during the early days of sparkling wine production. Pressure inside a bottle of Champagne can reach up to 90 psi, which is even higher than many car tires.

Today, punts also help sommeliers pour elegantly and allow sediment to collect in older wines.

Fun extra fact: a standard 750mL bottle of Champagne contains roughly 49 million bubbles.
