Wine shipping is simply the act of importing or exporting (Going to or from a country with a given product) wine itself. It can in some ways be complicated due to the laws of a given country, or have tariffs (taxes assoxiated with import/export of specifict goods) but wine is commonly easy to ship. The shipping is notable simply because wine is only able to be made well in a handful of places on the planet due to climate and seasons, meaning most wine is made there and exported across the globe, thus, wine shipping.
