If you are looking to "post" (ship) wine bottles, there are strict legal and safety requirements to follow:
: Local or online retailers such as Northern Brewer typically stock standard 750ml bottles and corks for DIY projects.
: Use specialized Styrofoam shippers or cardboard inserts to prevent breakage.
: In the U.S., it is generally illegal for individuals without a license to ship alcohol via FedEx or UPS; USPS does not allow it at all.
: It is often more cost-effective to carry a few bottles in checked luggage than to use an importer.
