Within a grape region, the site is important in determining where to plant. The site is the local position of the vineyard. Sites cannot be standardized, and therefore no two are alike. The cardinal natural factors to be secured in a site are warmth, sun, air and freedom from frost. These factors have been discussed in a general way under the climate of grape regions, but one needs to particularize a little more closely to ascertain how they affect individual vineyards. Warmth, sun, air and frostlessness are best secured by proximity to water, high land and proper exposure.
