Buenos Aires wines
The Buenos Aires Province has become a producer of premium wines during the first decade of the 21st century. Vineyards are located at the southern part of the province, specially around Médanos. The activity was pioneered in lands previously dedicated to garlic and pastures. Wine from Médanos won a Silver Medal in the 2009 Decanter World Wine Awards, the world's largest wine contest celebrated in London.
Climate and geography
The Médanos terroir has unique conditions ideal for quality vineyards. The soil is sandy, and given its latitude (around parallel 39° South, where the Pampa region and Patagonia converge) vineyards receive long hours of sun light, which result in grapes with high sugar contents. Windy springs help develop thicker skins that contribute to the intense color of these wines. 
Médanos appellation is a geographic indication applied to wines produced in Médanos (Buenos Aires, Argentina) whose characteristics are a function and a direct result of the geographic area and the terroir in which the grapes are grown and the wines are produced and aged.
Médanos appellation wines include:
- Sauvignon blanc
- Cabernet Sauvignon
- Cabernet Franc
- Petite Verdot
The closeness to the ocean and the strong winds in the area develop thick skins in the grapes that contribute to complex wines with intense colors.
