Aspect - Influence on Grape Quality
A cooling technique developed by University of Adelaide in Riverland. This is to delivering water directly to the roots and surrounding soil by under-canopy sprinklers in the night before a summer scorcher can reduce daytime canopy temperatures by as much as 5C below ambient temperatures. Using misters to lightly spray the canopy during the heat of the day is even more effective, dropping the temperature by 10c – 12C. This technique ensures vines do not shut down even when temperatures hit the mid 40s. The drawbacks of the misters are more expensive to install and the mister heads have to be removed before pruning or harvesting as they can get tangled in machinery.
