That Dimple In Your Wine Bottle Serves a Purpose
Also referred to as a “kick-up” or a “punt,” the dimple in the bottom of the wine bottle is a remnant from the past, when the bottles were made of handblown glass. If the glassblower didn’t push the seam of the bottom of the wine bottle up, it would not stand up straight (because there would be a lump).
Also, here’s a handy tip for burgeoning oenophiles: many experts say that if you’re shopping for affordable wines today, a deeper punt means it’s a nicer, tastier bottle of wine. So always be sure to run your hand underneath it before purchasing.
