Wine documents are used for legal purposes such as the transfer of ownership of a winery, the registration of a wine label, or the filing of a trademark application. They can also be used to document the production process of a wine, including the grape variety, the vintage, and the winemaking techniques used. Wine documents can also be used to record the sale of a wine, including the buyer, the seller, and the price. Finally, wine documents can be used to track the distribution of a wine, including the locations where it is sold and the quantity of wine sold.
