El Cadastro is a blend made from 4 parcels of older vines planted in the 1930s and 1950s. As was the custom at the time, these primarily Tempranillo vineyards are co-planted with smaller percentages of other varieties. Most of this cuvée comes from the sub-zone of La Tizona, which Olivier feels gives this wine its innate floral aromatics, to which he adds a portion of fruit from the sub-zones of La Mula, El Amesado, and La Quemado – the high plateau considered by most to be the Grand cru of Covarrubias.
