The acquisition sees the Californian Estate join Chanel’s existing portfolio of Bordeaux wines, which it first began purchasing in the 1980s.
Industry experts believe it will help Chanel gain a foothold in the lucrative US wine market, which is currently one of the most buoyant in the world.
"I am delighted to hand over St. Supéry to such a well-regarded company that understands luxury brands and will continue to enhance this special property," said Robert Skalli, creator of the St. Supéry Estate.
Located in the northeastern Napa Valley, the St. Supéry estate was created in the 1980s and is spread over more than 600 hectares of land. The estate has won many awards over the years and specialises in Sauvignon Blanc and Cabernet Sauvignon. It produces more than 100,000 cases a year.
Founded in Paris in 1909, Chanel has grown to become one of the world’s most famous luxury brands.
