This technique dating back to the early 17th century was reserved for the production of a prestigious wine called Sforzato or Sfursat in the dialectal jargon.
The grapes used to produce “Sfursat” can come from both the Rosso di Valtellina DOC area and Valtellina Superiore DOCG area provided that the yield is contained within 80 quintals per hectare and the bunches are chosen according to the following factors:
- open bunches;
- flawless health;
- perfectly intact skin.
Chiavennasca (Nebbiolo) grapes are harvested in the first ten days of October. Carefully arranged in small boxes of 5 – 6 kg or on racks, they are then left to dry in special ventilated rooms called “fruttai” until early December, so that the weight loss reaches 30% – 32% of the initial weight. The result is a concentration of sugars, polyphenols and aromas such as to produce a dry wine with great personality and finesse, suitable for the most varied occasions and food-wine pairings.
