Last week the Vin en Vacances team payed a visit to Clos du Gravillas, a boutique winery farming organically on limestone soils in the Minervois. They wanted to taste some of the 2015 wines to see how they are maturing and here is team member Marcel Van Baalens report:On our vineyard tours we get to taste a lot of wines on a yearly basis! Don’t worry, the spit-bucket is our best friend. Tasting so many wines gives us a fairly good idea about the quality and the character of a vintage. But what makes a great vintage? Every vintage is different, and so it should be. To describe a vintage we have to look at all the four seasons. Vivaldi was right! But conditions may vary locally.We talked to John Bojanowski of Clos du Gravillas, a boutique winery in the tiny appellation of Saint-Jean-de-Minervois, famous for its sweet Muscat wine.
