Most likely, it is simply that a vast number of gradual refinements brought in over the past decade have all come together. Technical improvements abound, from stainless steel double-skin vats to optical sorting, and latest-generation de-stemming machines. In the vines, there is plenty of definition work going on, from soil analysis to adjustments of canopy cover, and vineyard work is carried out according to organic principles, with natural fertilisers and humus of vegetal origin. A permanent monitoring system has checked underground water movements for over ten years, ensuring water stress to the vines is fully understood, and so ensuring vineyard work can be planned accordingly.
