Of the almost 1,000 hectares that make up the Vega Sicilia estate, 210 are dedicated to the cultivation of vines, with nineteen different types of soil and fifty-five plots with very specific features. In the extraordinary management of these soils, the influence of the course of the River Duero and the passage of time have been crucial. Forty of these hectares are used to produce Unico, which is aged for a minimum of ten years between barrel and bottle, one of the longest ageing processes in the world. Both French and American oak are used, in new and used 225-litre barrels and 22,000-litre vats. Though long and complex, this maturation technique works wonders: the wines gain a myriad of nuances, a precise texture, and a wonderful depth over time. Thanks to this incredible terroir and unique ageing process, Unico can continue developing for decades.
