. On the vine, grapes are organized through systems known as clusters. Grape clusters can vary in compactness which can result in long clusters (resulting in the grapes spreading out) or short clusters (resulting in grapes packed together). In some grape species, clusters ripen collectively, which allows them to be harvested together. For others, grapes may ripen individually within a cluster. Each grape berry contains a pedicel which attaches to the

Although the skin contains the majority of the tannin, small percentages can be found throughout the grape and during all of its developmental stages. However, the tannin's most important role is during the grape's ripening stage as its function is to formulate color and body shape.

Climate

Climate is the most significant external factor in determining a grape's inherent qualities. Each grape variety has a uniquely preferred environment for ideal growing. Because climates vary from region to region, selecting the best strain is an important decision in grape cultivation. Additionally, because climatic factors such as temperature and rain can be unpredictable and uncontrollable, each year will produce unique qualities and yields of grapes. Wine grapes are also especially susceptible to climate change and temperature variation. Grape vines need approximately 1300–1500 hours of sunshine during the

s in the grape. Hot and sunny climates have a frost-free growing season of 200 days or more. These climates allow grapes to ripen faster with higher sugar levels and lower acidity. Cooler climates have a frost-free growing season of around 150–160 days. Cooler seasons force the grapes to ripen earlier, which produces a fresher and more acidic harvest. In general, the average yearly temperature for most crops should average around in order to achieve the highest quality in each grape. Summer: Ideal temperatures in summer average around . Ideal summer temperatures enable fruits to ripen. Temperature and sunshine are the most important factors in ripening. Winter: Ideal temperatures in winter average around . Ideal winter temperatures are necessary to allow grape vines to enter their resting phase. If temperatures fall too low, the crops can be injured. Spring and Fall: Spring and fall are critical seasons for grape development, because the plants are susceptible to frost damage, which can injure the fruiting buds. Wet weather in spring can increase the odds of mildew formation. To prevent mildew, some farms introduce devices such as heaters or large fans in vineyards. However, such solutions can be costly.

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 climes, north-facing slopes are preferred. In the southern hemisphere, these orientations are reversed.

Soil

Quality soil is important to allow plants to have better root systems. The growth and health of a vine can be affected if the

Green harvest

A green harvest is the removal of immature grape bunches, typically for the purpose of decreasing yield. The removal of the bunches while they are still green induces the vine to put all its energy into developing the remaining grapes. In theory this results in better ripening and the development of more numerous and mature flavour compounds. In the absence of a green harvest, a healthy, vigorous vine can produce dilute, unripe grapes. In Europe, many

s restrict the yield permitted from a given area, so there is even more incentive to perform green harvesting when presented with excess crop. Often, the excess must be sold for a pittance and used for industrial alcohol production rather than wine. While the concept of thinning or sacrificing part of the grape crop, i.e. green harvesting, with the aim of improving the quality of the remaining grapes, predates modern critics, the practice has increased in recent times in vineyards found in California and areas where the grapes grow easily.

Sustainability

Sustainable production meets the needs of the present generation without restricting the ability of future generations to meet their own needs. A more sustainable viticulture produces with as few resources and emissions as possible. From a holistic perspective, more sustainable viticulture also includes the subsequent processing and distribution chains and, ultimately, the consumers. At the end of the 1990s the increased implementation of beneficial and environmentally friendlier production methods, such as "integrated viticulture", "organic-biological viticulture" and "biodynamic viticulture" in the vineyards marked the beginning of a more sustainable production in some regions. Further measures to improve sustainability have been tried in projects: Examples include the combination with wood production. The use of sheep in vineyards (also known as integrated ''sheep''-''vineyard'' systems) would also be a viable dual-use system and could increase land use efficiency and biodiversity. However, the use of pesticides poses intolerable veterinary risks in many forms of implementation. So these risks severely restrict the temporal and spatial possibilities to introduce sheep in vineyards. The sowing of native wild herbs can generate very positive results for species conservation.
