Wine Regions of the World between 30-50 degrees of latitude
Where does wine grow?
Vitis vinifera vines (vines that are used in winemaking) can only live in a certain temperature range and can adapt only so much to extremes in climate. They grow best in mostly temperate climates. Extremes of heat and cold can only be withstood by a handful of specialized varietals. This limits the growing of grapes and the production of wine to areas of the worl that are
- Far enough from the equator, where regions are closest to the sun and climates are hottest.
- Far enough away from both the North Pole and the South Pole, where the regions are furthest from the sun and climates are coolest.
Taking these into account, wine production is typically limited to the areas of the globe between the 30th and the 50th parallel of latitude in both the Northern and Southern Hemispheres.
