Concave bottle bases distribute gas pressure and collect natural wine sediment
The concave indentation at the base of glass wine bottles is called a punt. Historically, glassblowers formed punts to push the seam inward so bottles stood upright without rocking. Modern punts distribute internal gas pressure in sparkling wines and capture sediment poured from aged vintages.
