High-elevation wine growing requires a painstaking, labour-intensive approach. Thin, rocky soils and steep slopes make water retention challenging and erosion a threat, but the vines benefit from the struggle and produce concentrated flavours. The high altitude keeps midday temperatures cooler than those in the valley below, while the position above the fog line gives grapes longer daily exposure to sunlight. This regularly extends the growing season into November, and the increased hang time results in peak ripeness and full varietal complexity.
