NEGOCIANT
Négociants buy everything from grapes and grape must (pressed grapes that have not yet started to ferment) to wines in various states of completion. In the case of grapes or must, the négociant performs virtually all the winemaking. If it buys already-fermented wine in barrels or 'en-vrac' - basically in bulk containers, it may age the wine further, blend in other wines or simply bottle and sell it as is.
Négociants have operated in France for centuries. More than 190 négociant wineries operate in the Bordeaux region alone. Some négociants, such as Georges Duboeuf, have a recognizable house style and have become world famous for their wines. Many négociants also own vineyards. In Burgundy for instance, Duboeuf and Louis Jadot, are the largest owners of vineyards.
