The altitude has two effects on the vines. The first one is the thermal amplitude. The significant difference in temperature during the day and night increases the concentration of color and aromas in the grapes. Situated at an altitude of 1,100 – 1,300 masl, the vineyards we have chosen in Chacayes, Altamira and Gualtallary enjoy an ideal location with regards to thermal amplitude. Maximum temperatures are high (around 31° C), but, still, they remain moderated due to the altitude. Minimum temperatures are low (9° C) because they are affected by the cold air mass that goes down the mountains. The average thermal amplitude in the regions we have chosen fluctuates between 16 and 22°C, which is totally exceptional, even within the Uco valley.
The second consequence, not minor, of the altitude is the clear, strong and intense light that inundates our vineyards. This light also generates a slight stress on the plant that contributes to the concentration of aromas and color of our grapes.
