Diprovin is a bulk wine merchant and was founded in 1960 by Monsieur de Rivoyre, a wine broker in Bordeaux. It joined Grands Vins de Gironde in 1991. From its origins, its business has been to deliver to the mass distribution network in France and Europe. Diprovin is the leader in its field in Bordeaux, supplying bulk wines that meet the analytical and qualitative standards set by its customers. The wines are kept in an ageing cellar that contains 4000 barrels and a winery with a capacity of 160,000 hl; the company can therefore commit itself to considerable volumes. This large stock capacity combined with efficient logistics means that the wine can be delivered very quickly, with a quality of service that is based on flexibility and reactivity.
