Grape Vine Training and Pruning Methods Flashcards
What is cane pruning also known as?
Guyot - commonly used in cooler climate growing regions, including Burgundy, Sonoma, and Oregon. By limiting the vine’s lignified growth (the hard brown part) to just the trunk, the vine is less vulnerable to frost and better protected than spur pruned vines. Cane pruning takes great skill to do well because it requires manually cutting back nearly all the vine’s prior growth and correctly selecting a single cane (or two) that will be responsible for next season’s production.
Cane pruning has been adopted by many of the world’s most prestigious wine growing areas.
What I spur pruning also known as?
Cordon - is common to see in warmer climate growing regions, including California, Washington, and Spain. There are many different styles of Spur-pruned training methods used for everything from table grapes (high production) to fine wine (low production). Spurs (the stub of a cane that contains 1-3 buds) are generally easier to prune and certain training systems, such as goblet method, are ideal for areas prone to drought.
Spur pruning is a more traditional training method that is known to produce outstanding old vine wines.
What is a cordon-trained vine?
The vine has at least one permanent cane that extends from the trunk, called an arm or cordon. It grows thick and gnarled over time, and fruit-bearing shoots will emerge from it each season.
What is a head-trained vine?
Head-trained vines have no permanent cordon, and the trunk ends in a knob, or head.
What is a spur?
The spur is a cane cut back to two buds.
Define the Guyot method.
The Guyot system requires a vertical trellis on which the canes can be suspended, and has one spur and one main two-year-old cane.
What is the simplest form of spur-pruning/head training?
The Gobelet system, an ancient technique common in the Southern Rhône and Southern Italy, wherein the vine, often unsupported, resembles a goblet, with each year’s fruiting canes extending from the spur-pruned, shortened arms atop the trunk.
What is the Gobelet system also known as?
Italy - Albarello
Spain - En Vaso
Australia - Bush Vines
What is one of the simplest spur-pruned/cordon-trained systems?
The Cordon de Royat, the preferred training style for Pinot Noir in Champagne. The Cordon de Royat system is similar to the Guyot system, with a single spur-pruned permanent cordon extending horizontally from the trunk.
What is VSP in Grape Training?
Vertical Shoot Positioning - A trellising system, may be used for either cane-pruned or spur-pruned vines.
What is the Tendone system also known as?
Known as pergola in Italy and enforcado in Portugal, is an alternative training system in which the vines are trained upward and overhead along wooden frames or trees, enabling workers to pass underneath.
