The 2012 Cosecha Especial Brut Nature is a 50/50 blend of Pinot Noir and Chardonnay from Gualtallary in the Valle de Uco. It was kept in tank with the lees for one year followed by one and a half to two years sur lees in bottle. The wine is disgorged as the wine is shipped, so you can find bottles with more yeast contact. The nose is fresh, combining notes of white fruit with yeast aromas, with some hints of fennel and aniseed. The palate has effervescent bubbles, quite abundant, with acidity and a slightly bitter finish. It feels young and dry, no dosage is used. 20,000 bottles produced. Norton produces quite a lot of sparkling wine, and this one is their top of the range.
