The Brancaia method is the one-armed cordon. The cordon is tied to a steel wire 20 in. from the ground. This results in the grapes hanging close to the earth, thus collecting the warmth reflecting from it for their ripening. The primary basic vine is the type 420 A (Berlandieri x Riparia). It sends limited strength into the plant, adapting to the lean and relatively dry soil.
The high density of plants (2400/a.) is a Brancaia specialty. Thus the yield per plant is low: each vine gives approx. 2 pounds of grapes which is less than a 0.75 litre bottle. A traditional planting system, i.e. 1100 wines/a., would yield that much only if each vine produces approx. 4 pounds of grapes. There is another advantage of close planting: the vines have to compete for nourishment and are subject to a moderate stress situation which leads to earlier ripening and a reduced yield per plant. |
