The grapes for our KAI were selected from the best blocks of our Max vineyard in the Valle de Aconcagua, a region with a Mediterranean climate that includes a long, dry growing season, rainfall concentrated in winter, and moderately warm summer days cooled by soft evening breezes blowing in from the Pacific Ocean. The vertically-trained Carmenere vines were planted in 1992 and 1993 in deep loamy alluvial and riverbed soils with 30 to 50% stone content. Average yields here range from 1.5 to 2 kg per plant, which enables good fruit set and vigour control, resulting in wines with outstanding concentration, colour, and volume. The grapes were harvested quite late in the season to ensure the flavours deliver good fruit expression without herbaceous notes. The high daytime–night time temperature variation (averaging 19°C/34°F) in the weeks leading up to the harvest triggers high concentrations of anthocyanins, which intensify the colour of the wines.
