There are many forms of vineyard support and formation. We must always choose a conduction system that allows us to have a good quality of development and formation of the plants, and especially, a conducting system that provides us with a good leaf area exposed to the sun, which results in healthy grapes and with a good index of maturation. In our vineyards, we adopt the “ESPALDEIRA” system (aka “Live Fence”) for an economic scale of wine intended cultivation (such as Cabernet Franc), the “LATADA” system (aka “pergolado” or “caramanchão’) for large scale grape cultivation intended for table wines and juice production; the “Y” system is used on the Experimental Field, which allows better observation of the wineyard evolution.The main factors that favor harvest and production of quality grapes:

 

Vineyard Location

When choosing the location of the vineyard we should prefer the slopes, as they have good drainage, and avoid the low places, as they are more humid. As for exposure to the sun, we should locate the vineyard so that it receives sunlight all day, or for most part of it. But most importantly, it should receive the first solar rays of the morning, as these will evaporate the dew before the temperature rises, thus reducing the risk of disease. For this reason, we must give preference to the North and East exposure, as is the case of the vineyards of Vinícola Góes.

Type of Soil

The vine adapts itself to many types of soil. If we analyze the types of soil used in the cultivation of the vine in the different wine regions of the world, we will find that they vary from very sandy to the heavy clays; from thin soils to very deep ones; from soils with low fertility to those with high fertility. The Góes’ vineyards are planted in a strip of soil called yellow red Lato-soil of good depth, which provides a good development of the vines thus creating good raw material.

 

Conduction System

There are many forms of vineyard support and formation. We must always choose a conduction system that allows us to have a good quality of development and formation of the plants, and especially, a conducting system that provides us with a good leaf area exposed to the sun, which results in healthy grapes and with a good index of maturation.

PRUNING SYSTEMS:

- TRADITIONAL PRUNING

 At the traditional crop, we realize one single prune, in order to balance fruiting and vegetation. This way we eliminate most branches of one year - those that fruited, leaving only small pieces of them. In the prune execution, we must distinguish three intensities of pruning: short, long and mixed.

Short pruning: those in which the rooted cuttings keep 1, 2 or 3 gems - in this case, spurs.

Long pruning: those in which the rooted cuttings keep 4+ gems. The rooted cuttings toppings are called “vara”.

Mixed pruning: those in which the rooted cuttings keep spurs and “varas”.

- Inverted pruning, double pruning or vineyard cycle inversion

This type of handling is made with the objective of fruiting plants during winter. There are basically two prunes: one in August, and the other in the end of December. The first one is made so the productive branches can be formed and the second one is the effective fruiting prune. The plant starts to sprout in January, flourish in February, the clusters start to form in March, and at the beginning of July, the harvest.

 

Maturation Control

 The initial phase of maturation takes place when the red grapes are slowly changing color and the white grapes start to soften the berries. From this stage the grapes begin to accumulate sugars and phenolic compounds responsible for the color and aromas, while the acids are decreasing, these indexes are controlled through physical-chemical analysis of the samples of the grapes collected from the vineyard to be evaluated. The degustation of berries is also done and the sanity of the bunches is also evaluated in order to determine the exact moment of harvest.
