Most vineyards in Burgundy, even the tiniest ones, have more than one owner.
It’s common to think of a vineyard as a piece of land owned by a single vintner. In other words, vineyards are usually defined by the legal construct of a given person’s ownership. Even though the property within a vineyard may contain highly variable terroir, it is still considered one vineyard when it’s owned by one person. The opposite holds true in Burgundy, where “vineyards” and their names define a distinct terroir as observed and established centuries ago by monks attempting to define parcels of ground. Most named “vineyards” are subdivided into multiple parcels, each owned by different individuals. Perhaps the most well-known example is the Grand Cru vineyard Clos de Vougeot. At 125 acres (50 hectares; less than half the size of, say, Château Lafite Rothschild in Bordeaux), Clos de Vougeot has 80 owners. Each of these owners makes a wine called Clos de Vougeot. That said, a handful of vineyards in Burgundy have only one owner. These vineyards are known as monopoles and they are rare.
