NB: excludes Aurelio Montes’ experimental <1ha recently planted in Peru at 3,000m
NB: Just missing the cut: South Africa and Switzerland, both with vineyards at 1,150m.
- Temperature decreases by about 0.6°C to 0.8°C (depending on latitude) per 100m increase in altitude above sea level (asl)
- Diurnal temperature range increases with higher altitude asl. Lower night time temperature reduces respiration rate, particularly of malic acid, of grapes.
- Ultraviolet radiation increases with increasing altitude asl. Increased photosynthesis: thicker skins, more anthocyanins and polymerised tannins.
- Growing seasons shorten between 2 and 4 days per ~100m increase in altitude asl. Vine growth can still be strong because of greater UV and higher diurnal temperature range
- Carbon dioxide uptake is lower at higher altitude asl, which limits photosynthesis. Vine growth may be stunted.
- Risks such as frost, hail, winter hardiness, winds and higher production costs increase with higher altitude asl.
