Overview

Altos Las Hormigas is a winery brand focused on Malbec from Mendoza, Argentina. According to its official site, in 1995 Italians Alberto Antonini, a Tuscan winemaker, and Antonio Morescalchi, a young entrepreneur, traveled to South America and were impressed by high-altitude vineyards in Mendoza's desert climate. They decided to found a winery dedicated exclusively to Mendoza Malbec. The brand describes its wines as authentic, seeking mountain freshness and fruit character rather than modern 'fruit bombs' or heavy oak. Its wine lines include Altos Las Hormigas, Jardín de Hormigas, Colonia Las Liebres, Cahors, and La Danza.

History

According to the official 'Nosotros' page, in 1995 Italians Alberto Antonini, a recognized Tuscan winemaker, and Antonio Morescalchi, a young entrepreneur, traveled to South America to learn about wine regions. They visited both sides of the Andes and were strongly impressed by vineyards developing at high altitudes in a desert climate like Mendoza, Argentina. They returned to Tuscany convinced of the unexplored potential of Malbec, a grape with strong local tradition but generally ignored and misunderstood. Against predictions and local advice, they decided to start a winery dedicated exclusively to Mendoza Malbec. The page also explains the name: when their first vineyard was planted in 1996, workers had a tough altercation with local ant colonies, and the estate is mainly surrounded by uncultivated fields.
