Chile's central zone has Mediterranean climate with a broad oscillation between daytime and nighttime temperatures, an average humidity of 55-60%, and maximum high temperatures above 30 �C (86 �F) in the summer. Temperatures are lower near the Andes due to the cold air from the mountains, and the area closer to the Coastal Range has less daily temperature oscillation due to the maritime influence. Grapes from a selection of vineyards on silty soils with excellent drainage at the foot of the Andes Mountains are carefully combined with those from vineyards located in an area near the Coastal Mountains where the soils are heavier and have a combination of silt and clay. Vinification: The grapes were handpicked during the month of April. They were destemmed, crushed and cold macerated during 5 days for color extaction and fermented at 24�-28 �C (75�-82�F), 10% oak was used during fermentation to help set the color and stabilize the wines. Once the alcoholic fermentation was completed, 20% of the wine was aged in French oak for 3 months to lend sweetness and increase complexity.
