In 2001, Alta Vista became the first Argentine winery to produce single vineyard wines. Alta Vista developed its Terroir Management® system for wine growing and winemaking, wherein grapes grown in distinctive sites express the true characteristics of each vineyard through distinctive wines. This vineyard is sited at over 3,000 feet in altitude in Valle de Uco, and the vines are over seventy years old. This light soil is sandy with some silt, is very permeable and has boulders and a broken layer of limestone at a depth of 2.5 feet. Traditional irrigation is fed by water from the Andes Mountains. Temis has the coldest climate of all Alta Vista’s terroirs. Nights are quite cool and days are warm and soft, with constant breezes that help to keep the vines and grapes healthy. The grapes have a slow, gradual cycle of ripeness that is balanced and ideal.
