A belief is held by enologists and viticulturists that the wine is actually made in the vineyard. This belief is based on the effect of the fruit's quality upon the finished wine product. The quality of fruit is influenced by a multitude of factors. Such factors include climate, soil, fertilizers, pests, disease, clones, vineyard configurations, trellis styles, water and viticulture practices. A few of these factors are beyond the viticulturists control. However, those that can be controlled must be precisely honed to produce the best fruit quality. While some of the practices are universally accepted, others vary according to region, soil, climate, configuration and even personal preference and end result goals.
Cabernet Sauvignon, for example, may produce anywhere from one to ten tons of grapes per acre. Obviously, a higher quantity of fruit on the vine produces a lower quality of wine. Vineyard practices dictate that when aiming for the highest quality of wine, the grower should limit both the number of canes and fruit bunches per plant, thus lowering the total production of each individual plant.
The configuration, or planting pattern of the vineyard enters the equation of a fine wine as well. A three foot by three foot pattern would result in as many as 4,840 plants per acre. In this case, the vines are planted at three foot intervals in rows three feet apart. A pattern of eight feet by twelve feet, that is, plants spaced eight feet apart in rows twelve feet apart, would result in only 454 plants per acre. There are those that feel that plant competition ultimately benefits fruit quality.
Shown below is a table showing production figures based on the production of five tons per acre. In the Cuyama/Ventucopa area, we expect one to four tons per acre depending on the age of the vines. Most of the vineyards in this area consist of younger vines that are still maturing.
