A punt is the concave bottom of a 'better' wine 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.
