storage and shipment. Even after corks became the standard, they were often unreliable. Wine would leak out and oxygen would sneak
in, harming the wine, so wax was used to create a stronger, more airtight seal, particularly for bottles meant for longer aging.
Today wax is mostly used for aesthetic purposes, as corks are much more adept at properly sealing wine bottles, even for long
periods of time. But experts still feel that an additional seal is necessary.
“Experience has shown us … that no matter how good the cork’s seal, it can never be perfect … unless it has an additional external
cap to protect it,” but these sealing wax allows them to hold their top wines for decades without the need to re-cork the wine.
Wax seals also provide an additional guarantee of the wine’s authenticity, as it would be difficult to falsify the contents of the
bottle by opening and resealing it.
