It is particularly useful for vines of high vigour. Champagne is the only AOC to have laid down such a precise and comprehensive set of rules for pruning.
Loire Tastings. The shoots are wound around the supporting wires then attached with paper-covered wire or some other biodegradable fastening.
The system was developed in France in the late 1800s and is named after Dr. Balancing the shape of the vinee Pruning gives the vine its shape and prepares it for summer maintenance. Vigorous vines are not well suited to the Guyot system, and will result in high shoot density and inner-canopy shading, reducing leaf surface area exposure.
This is particularly true of those who have land suitable for mechanisation, such as many Italian vineyards. With this long established system, the fruiting canes are trained upwards from the trunk, and it is thus also known as vertical shoot positioning or simply VSP.
At pruning the two year old cane, and consequently much of this years growth, are completely removed. It is, like the Guyot systems, subject to cane pruning , although there is a similar training method for spur pruning see the Smart Dyson method. The different methods assist in controlling vigorous vines that produce too much foliage and not enough fruit, may increase exposure of the foliage to light, improve air movement through the leaf canopy and thus reduce the risk of rot, and they may facilitate mechanisation of pruning or harvesting.
Where to Buy Wine. The buds require an even distribution of sap for vigorous growth but excess sap may compromise productivity. Have a Question?
Pruning methods used in Champagne There are four approved pruning methods. In fertile soil the foliage may be so prolific as to dangle on to the ground, and this is also undesirable. It resumes in mid-January, after the dormant winter period, and continues until late March.
The canes are supported by securing them to a number of trellis wires running the length of the row of vines. Conclusion To conclude, I must stress that this is merely an overview of the most common methods of vine training, particularly those used in France and the New World.
Many dozens of different training techniques have been developed, some of which have been in use for centuries, such as gobelet , and some for just decades, such as Scott Henry and Smart Dyson. Scott Henry This system for vine training is essentially a variation on the Double Guyot system. It regulates growth, promotes productivity and encourages good ripening.Cane Pruning
Patty Skinkis, Oregon State University The Guyot training system is a part of a group of systems referred to as a VSP system vertical shoot positioned; other examples include the lyre system. This system may be seen in Bordeaux, Burgundy and Champagne, using a short trunk with close planting to increase vine stress.
It was developed by Oregon winemaker, and retired aerospace engineer, Scott Henry, and thus eponymously named. Regular rejuvenation pruning can solve the problem by stimulating the buds from which new growth will arise to replace old wood.
Precise, expert pruning is essential for the quality of the harvest.
