Argentina Wine Regions: Technical Profile

Introduction

Argentina is the leading wine-producing country in South America, recognized globally for its diverse terroirs and exceptional quality. With a winemaking history spanning over 400 years, Argentina combines old-world traditions with innovative techniques to craft distinctive wines.

The country’s viticultural success is rooted in its geography, with vineyards sprawling along the foothills of the Andes Mountains. These high-altitude sites, ranging from 500 to over 3,000 meters above sea level, create unique microclimates that promote balanced acidity, concentrated flavors, and aromatic intensity.
