The most southerly wine region in South America, Rio Negro runs along the
river of the same name. It’s a small region, with only 1,600 hectares under vine,
but vines have been grown here since the 1800s. The altitude (at 250 m.a.s.l.) is
low by Argentine standards but due to latitude, the region still enjoys the wide
diurnal temperature variation that gives a long growing season. Alluvial soils, with
a significant limestone component, support production of excellent cool-climate
Pinot Noir. The grapes for this wine come 60% from the town of Mainque and 40% from San Patricio del Chañar. The harvest is done by hand and fermentation takes place with 25% whole bunches, at a temperature of 25-28 ºC. The malolactic fermentation takes place in 80% used and 20% new French oak barrels. The wine rests in the same barrels for 11 months before being bottled.
