The foundations of Vega Sicilia's traditions may be found as far back as 1859, when Don Eloy Lecanda Chaves was gifted an estate by his wealthy father. The origins of the Vega Sicilia winery are officially regarded as 1864, which was when Don Eloy Lecanda Chaves returned from his travels in Bordeaux with vine cuttings, including Cabernet Sauvignon, Malbec, Merlot, Carmenere - all of which were found in Bordeaux at that time - and, curiously, some Pinot Noir. Regardless of how Pinot Noir arrived, the cuttings were duly propagated and planted at Vega Sicilia, although the Carmenere and Pinot Noir are no longer found in the Vega Sicilia vineyards.
Vega Sicilia's Tempranillo is trained in gobelet fashion, whereas the French varieties are trained in a Guyot system. Green harvesting is employed ruthlessly in order to control yields, and the harvest itself is meticulous. In the winery, such a massive wine will withstand many years in wood and Unico sees a complicated series of rackings from huge barrels to new oak, to used American oak, back to new oak again, and on it goes. Whatever these phases are called, Unico certainly receives very prolonged barrel ageing, with the 1970 seeing over sixteen years! And yet these are not washed out, stretched, overly oaky wines when mature, testimony to the quality of the raw materials on which they are based.
