Not sure what date this is from but some fun info.



A punt is the concave bottom of a 'better' wine bottles . The earliest origins of the punt are lost in history but there is much conjecture. Punts likely existed either for strength of the bottom of the bottle (especially with sparkling wine) or in order to form a stable (non-rocking) bottom in the hand-blown bottles. Today a punt is unnecessary and exists only because many consumers equate the presence of a punt as an indication of quality. Modern glass technology allows bottles to be made that do not require a punt for strength or stability for either sparkling or still wines.
