The berries of this Merlot grapes variety grown at a mild cold temperature climate, but with the contrast of warm days with cool evenings producing a benefitial difference of temperature between day and night. Clusters were hand-picked into half-ton bins and the cluster selection was perform on the vine, with leaf removal prior to vintage. Harvested only in the early morning hours to keep the fruits cool. The vines from where the grapes for this wine come from are planted over alluvial origin soils, on stony, clayish and sandy river beds. Hillside planting, stratified and slightly undulated, of medium depth and loamy texture good drainage and low vigour. During vinification the grapes from harvest were destemmed, soft crushed and carefully managed in order to protect them from oxidation. Winemaking was done at a controlled temperature of 25°C. The clusters were crushed carefully and then a cool pre-fermentation maceration was given in the stainless steel tanks at 59ºF (15ºC) for three days. Post-fermentation maceration was given for about two weeks and fining was done by press fractions based on constant tasting, with no “press wine” included in the blend.
