Alpi Retiche di Sondrio Bianco IGT “Ca’ Brione” Nino Negri is a rare blend, where next to the white grape varieties there is also a 10% of chiavennasca, or Nebbiolo, obviously vinified in white and therefore without contact with the skins. The grapes to produce Alpi Retiche di Sondrio Bianco IGT “Ca’ Brione” Nino Negri were fermented off the skins after a very gentle pressing. The Terrazze Retiche di Sondrio Bianco IGT “Ca’ Brione” Nino Negri white grapes were fermented naturally at a temperature of 18- 19°C in French oak casks, half new and half twice-used, while the Nebbiolo-Chiavennasca was fermented at a controlled temperature in special fermentation vessels. The white grapes were left in barriques with bâtonnage every seven days, while the Nebbiolo-Chiavennasca was placed in stainless steel. All the grapes were fermented and aged separately before blending in mid-May.
The grapes for this white wine were first harvested in 1986 in the vineyards of the Fracia cru in the municipalities of Teglio and Chiuro and the Tresivio basin.
Casa Vinicola Nino Negri, founded in 1897, is headquartered in Chiuro in the old fifteenth-century Castello Quadrio. Casa Vinicola Nino Negri is one of the most renowned wineries in Valtellina and a synonym for Valtellina wines all over the world.
Nino Negri owns 31 hectares of vineyards across the most prestigious of the Valtellina Superiore D.O.C.G. subzones: Inferno, Sassella, Grumello, Fracia, a monopole vineyard located in the Valgella subzone.
Due to the extremely steep hillsides, Nino Negri’s estate is characterised by terracing, a system based on dry stone walls that support the terraced hillside vineyards built thousands of years ago to allow cultivation of the land. The sandy, silty base tends to be dry as it retains very little water and is highly permeable. The shallow soil has an arable surface of between 40-120cm and it is common to see vines take root in the cracks between the rocks.
The steep hillsides provide the perfect environment for Nebbiolo to thrive in. The steep slopes allow optimum exposure to the mountain sun as well as protection from the cold winds, and the wide temperature ranges between day and night encourage the expressive uniqueness of the king of grape varieties, Nebbiolo, locally called the Chiavennasca.
Great commitment is needed at every moment of vine cultivation in Valtellina, a difficult and labour-intensive area to cultivate. For over 100 years, Nino Negri has given this commitment, nurturing the grapes’ potential and literally handcrafting wines of superior quality and character.
All vineyard work, including vineyard management and harvest is done entirely by hand along the terraces supported by a myriad of age-old dry stonewalls, a symbol of this valley. During the harvest the grapes are transported down the mountain by helicopter so as to get them to the winery as quickly as possible.
