For family-owned wineries, their name can be everything. Family-owned wineries proudly promote their heritage and often multiple generations of ownership by brandishing their bottles with the family name. Signs for vineyards and tasting rooms, along with marketing materials, prominently tout the family name to identify the winery and its products.
In many ways this has little difference than with other products. After all, many of the largest, most successful American businesses use trademarks comprised of a family name—FORD, DELL, and McDONALD’S, just to name a few.
