Which factor is most responsible for high-acid, aromatic wines at altitude?

• A. Strong sun exposure.
• B. Heavy rainfall.
• C. Low sunlight.
• D. Cool winds.

Answer: (A)

Intense sun exposure at altitude drives aromatic intensity and helps preserve acidity. The strong sunlight pushes the development of aroma precursors and varietal character, especially in aromatic varieties. At the same time, the cooler nights that accompany high elevations slow the loss of organic acids, so grapes reach flavor maturity while retaining higher acidity. That combination—bright sun plus diurnal cooling—produces wines that are both high in acidity and highly aromatic. Heavy rainfall, low sunlight, or cool winds don’t promote the same balance of fresh acidity and vibrant aroma in high-altitude conditions.
