Punt: The dimple or indentation in the bottom of a bottle, originally meant to strengthen hand-blown glass containers; now mostly for show, except in sparkling wine bottles. Bottles for Champagne and sparkling wines, which must withstand extra pressure, have especially deep punts.

葡萄酒瓶底凹槽：瓶底的凹陷，原本是为了加强人工吹制的玻璃容器的坚固性，现在多为了美观，尤其起泡葡萄酒瓶。 香槟酒和起泡葡萄酒的瓶底凹槽非常厚，以承受外加的压力。
