About Vino – Its about lines of latitude
Although many factors can affect the overall quality of a grape vine, the three most important are one: Climate being the most significant factor in determining a grape’s inherent qualities. Each grape species has a uniquely preferred environment for ideal growing. Because climates vary from country to country, selecting the best strain is an important decision in grape cultivation. In addition, because climatic factors such as temperature and rain can be unpredictable and uncontrollable, each year will produce unique qualities and yields of grapes. Two: As to the terrain, hillsides and slopes are preferred over flatter terrain: vines growing on a slope can receive a greater intensity of the sun’s rays, with sunshine falling on an angle perpendicular to the hillside. In flatter terrain, the intensity of the sunlight is diluted as it spreads out across a wider surface area. Small slopes that are elevated above surrounding ground are the best and safest places for crops, because these small elevations are less prone to frost. Additionally, a slope affords better drainage, obviating the possibility that the vine might sit in overly moist soil. In cooler regions of the northern hemisphere, south-facing slopes receive more hours of sunlight and are preferred; in warmer climates , north-facing slopes are preferred. In the southern hemisphere, these orientations are reversed slope, and soil are especially critical to it’s success. As to the soil, when root growth is restricted due to bad soil, vine growth and fruit yields lessen and plant survival rates can drastically drop in a few years. The vast majority of the producing vineyards are found between the temperate latitudes of 30° and 50° in each hemisphere. Within these bands, the annual mean temperatures are between 10 and 20 °C (50 and 68 °F). The presence of large bodies of water and mountain ranges can have positive effects on the climate and vines. Nearby lakes and rivers can serve as protedtion for drastic tempereature drops at night by releasing the heat that the water has stored during the day to warm the vines. The angle of the sun is also a very important contributor to wine growing, as vines growing on a slope can receive a greater intensity of the sun’s rays.
