Unico is beyond any doubt the crown in the jewel of Vega Sicilia wines and wineries that also include Alion, Pintia, Macan and Oremus in Hungary. It carries the reputation of one of the most ageworthy wines in the world on par with the first growths of Bordeaux.
Elisa Kwon de Alvarez who is currently working on her theory part of the MW exam, having successfully passed the practical section talked about the history and the factors that make Unico such a unique wine. The winery was founded in 1864 and has been owned so far by four families with the Alvarez family being in control since 1982. This is the year that Ribera del Duero acquired its DOC status. At that time there were just 14 wineries in the region, now approximately 300 exist.
Out of the nearly 1,000 hectares that make up the Vega Sicilia estate, 210 are used to grow vines and only 40 are used to produce Unico; the rest source grapes for Valbuena and Alion. ''There is an almost magic element in the estate, something very special that one can see it starting from the berry weight, in Unico it is 1.6 grams while in Pintia (sister winery in Toro) it is 2 grams'' Elisa explained. She also emphasized on the attentive work in the vineyard and the rigorous selection that takes place during the harvest.
The entire vineyard is structured into 52 plots based on grape variety, age of the vines and the 19 soil classifications found on the estate. The minimum age of vines is 10 years old, the average in production is 35 while there are patches planted back in 1910 that are used to select clones working with a top nursery in Burgundy. So far Vega Sicilia has isolated, according to Elisa, top quality clones of Tempranillo that no-one has in Spain and the world. 20 clones have been identified over a two - decade period and next stage will include matching of rootstock with the specific clone.
Each plant – vine density is 2.222 vines per hectare - produces 1 to 1.5 kilos of grapes giving a total production of approximately 120.000 bottles (Valbuena is 200.000 bottles and Reserva Especial another 15.000). Fermentation is spontaneous with isolated yeasts while the greatest danger is spring frost. In this decade only one vintage was lost, 2001, but in the previous ones up to 3 vintages per decade were the norm, a big loss by all means. When temperature reaches -5 degrees Celsius everything budded in May is destroyed and a second crop does not have the quality to produce Unico, so it ends to Valbuena. The estate owns 15 wind machines that can protect up to -2 degrees Celsius, each costing approximately 150.000 Euros.
Vega Sicilia does not use any more concrete as according to Elisa Kwon de Alvarez the high pH of the grapes (goal is 3.6-3.7 but 3.8 is common) in not an ideal factor to work with concrete. Instead wooden tanks are used and after MLF the wine goes through what is probably the world's longest combination of maturation and ageing period of a red wine. That is almost 10 years between wood and bottle. The different stages take place in different types of barrel: American and French wood, new and used barriques, 20.000-litre vats, each batch is what determines the type of wood and the time spent in each container. It will normally spend 6 years in wood and 3 in the bottle and can be considered as the opposite of the en primeur system rewarding a long process of waiting for excellence.
Unico remains true to a clear and well-defined style, with an inimitable character and style; elegance, strength, ageing capacity... A unique and timeless taste that has elevated it to among the aristocracy of the great classic wines.
The Unico code
The Unico crest in the bottle shows the initials of each family that owned Vega at the time of the bottling; for example in the 1953 bottle shown below it is HN that stands for Hans Neumman from Venezuela that owned Vega from 1964 to 1982.
Furthermore, the qualities of the Tempranillo and Cabernet Sauvignon that consist the majority of the blend in different proportions are assembled to perfection in this wine. Each provides a differentiating factor that makes the wine great in every vintage.
