Study Cards on vines, bordeaux, vine
- vines are planted 1 metre apart with 1 metre between the rows.
Disadvantage: Close planting adds to costs as
- more plants,
- more trellising have to be bought,
- specialist over-row-tractors and
- more time is needed for vine training, ploughing and spraying.
Advantage: Close planting makes best use of expensive vineyard land
Note: Less prestigious appellations are often planted at lower density. AOC Bordeaux at 3-4000 vines/ha
1. On the left bank two canes are trained - Double Guyot. On the right bank single cane pruning is used - Single Guyot.
2. Some prestigious estates favour Cordon-pruning, spur pruning is
because it reduces yields and gives better aeration to the bunchens.
Leaf removal takes place during the summer and is intended to improve aeration and deter rot.
Also grapes get more ultra violet to aid ripening.
A disadvantage is that it can sun burn the grapes.
- Either by hand or machine
- They remove bunches to correct vines that are carrying a high yield or to improve concentration of flavour.
- An alternative is short pruning in winter.
- Harvest is done by hand and bigger estates have 100 pickers from other EU countries.
- Also machine harvest is done especially in the Northern Médoc (hard to get pickers because far from Bordeaux city / when fungal diseases are a threat) and for high volume inexpensive wines.
