Wine making falls into two parts: growing of the grapes aka viticulture, the turning of those grapes into wine, vinification (wine-making) Sunlight provides energy to produce sugars. Water combines with co2 to produce sugar, plumps out grapes. Warmth needed for growth and sugar production. Nutrients tiny amounts needed for vine survival. Climate and weather, winter hardiness, hours of sunlight, cycle of vine, resistance to mildew etc. Governed by tradition and in some cases law (old world) Wild vines grow widely throughout the world, but commercial vines are concentrated into two broad bands in the northern and southern hemispheres, roughly between 30- To fully ripen, red grapes need more heat and sunshine tan whites (min 1500 hours sunshine) Needs considerable amounts of water over a year (700ml) some drought tolerant less.
