Single Vineyard Alizarine was introduced in 2001, making Alta Vista the first Argentine winery to produce single vineyard wines. Utilizing their tailored Terroir Management system for wine growing and winemaking, Alta Vista uses grapes grown in distinctive sites to craft these unique wines that show the true characteristics of each vineyard. All Single Vineyard wines are aged for 12 months in new French oak barrels and an additional 6 months in bottle.
