Sourced from the Altamira district of San Carlos county, located in the southern Uco Valley at an elevation of 4,000 feet. Altamira has Mendoza's most unique soil profile, with a patchwork of sandy, silty and stony soils all present in the same vineyard. The stony soils contain a high content of surface stones and round rocks that are literally painted white with calcium carbonate. These patches of stony soil are very low in organic material and very high in mineral content. Their poor profile naturally brings down yields for an exceptional concentration of aromas and flavours. Their rocky character imparts a stony texture to the Malbec wines. The Manos Negras Stone Soil Select Malbec is made entirely from select Malbec grapes from these patches of stone soils.
