The Deep Holes On Wine Bottle Bottoms
So, what’s the deal with the indentations on the bottom of wine and champagne bottles? While some of us may have assumed they were there for show or as a decorative item, there’s a better explanation.
The indentations are designed to compensate for the pressure created by the contents of the bottle during the corking procedure. Bottle bottoms and sides are considered weak points and indentations help to equally disperse the pressure inside. Because champagne bottles are under so much more pressure due to the carbonation, they feature much deeper indentations.
