Vines are trained into a variety of styles that aid the growers in managing the canopy and controlling yields. The use of vine training systems in viticulture is aimed primarily to assist in canopy management with finding the balance in enough foliage to facilitate photosynthesis without excessive shading that could impede grape ripening or promote grape diseases.

Following fruit set, the grape berries are green and hard to the touch. They have very little sugar and are high in organic acids. They begin to grow to about half their final size when they enter the stage of veraison. This stage signals the beginning of the ripening process and normally takes place around 40–50 days after fruit set.
In viticulture, the grape cluster (also bunch of grapes) is a fertilized inflorescence of the grapevine, the only part of this plant used for food. [1] The size of the grape bunch greatly varies, from few grams to kilograms, depending on the grape variety and conditions during the fruit set .
The trunk of a grape vine trained along wires with one cordon extending horizontally to the left. The vine is the main part of the grapevine, extending from the root system in the ground up to the cordons, or arms, of the vine. When the grape is young the trunk is very pliable and must
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.
A plant on which grapes grow. Vine density The number of vines per a define area of land (acres, hectare, etc). This can be influenced by many factors including appellation law, the availability of water and soil fertility and the need for mechanization in the vineyard. In many wine regions vine density will vary from 3000 to 10000 vines per ...
The irrigation system that provides the most control over water management, though conversely the most expensive to install, is drip irrigation. This system involved long plastic water supply lines that run down each row of vines in the vineyard with each individual grape vine having its own individual dripper.
