Viticulture climate

Viticulture climate or macro climate.
Wine grapes grow roughly around the 30th and the 50th degree of latitude, on the northern as well as the southern hemisphere.
At a estimate daily temperature of less than 9,5 degrees the growth of a grape vine stops.
In a climate which is too warm you can sometimes harvest grapes 2x a years, but in that case the quality isn’t  sufficient for wine.
