This Semillon was sourced from forgotten vines that are over 50 years old. These old vineyards are located in Río Negro in Patagonia, at an altitude of 400 metres above sea level on the 39° latitude south. Sunlight exposure is more intense than northern areas, but at this latitude the nights are much colder. This daily diurnal temperature range is excellent for the production of quality grapes; the nightly cooling-off extends the ripening period, allowing the grapes to develop rich varietal characteristics while retaining balancing acidity.
