Vineyard Management Flashcards
For top quality Bordeaux vineyards planting densities are often ____ ____ at ____ per hectare
Vines are planted ___ ____ apart with ___ ____ between the rows. This is suitable for the relatively ____ ___ of the region resulting in moderate vigour
Closely spaced
10,000 vines per hectare
one metre
one metre
infertile soils
Close planting adds to costs as more plants and more trellising have to be bought, specialist ___ ___ ____ bought and more time is needed for ___ _____ _____ & ____
over the-row tractors
vine training, ploughing and spraying.
True or False?
Because of the land price, Close planting is the best use of land,
Because of this the planting in less prestigious appellations is higher density to make even better use of the land, often at 15,000-18,000 vines per hectare
False
close planting makes the best use of expensive vineyard land. Vineyards in less prestigious appellations are often planted at lower density. For example, vines for basic Bordeaux AOC are typically planted at 3–4,000 vines per hectare
What is the most common system of managing the vine?
head-trained, replacement cane pruned, in which canes are trained along wires
Double guyot is often seen on one side of the bank where as Single guyot is often seen on the other.
Which one is see more on the Left Bank?
Double guyot
The single-cane Single Guyot is more common on the Right Bank.
Which system of managing the vine is very uncommon to see but is used in very small amounts by some of the prestigious estates and why?
Cordon-trained, spur-pruned,
some prestigious estates favour it arguing that it reduces yields naturally and gives better aeration to the bunches.
In Bordeaux’s moderate, damp climate, canopy management is important to reduce the
incidence of ____ ____, ____ ____ and ___ ____ ___.
To combat this, what Summer pruning technique is practised?
downy mildew, powdery mildew and botrytis bunch rot.
Leaf removal takes place during the summer and is intended to improve aeration and deter rot. This also exposes grapes to ultraviolet light to aid ripening.
Lets say mildew attacks after a rain.
What trouble might you have when going in to spray?
tractors may have difficulty entering the vineyards to spray and the rain washes away the treatments, which can compound the problems
What does Soft pruning defend against and why?
Eutypa dieback and Esca (basically rotting the vine from the inside)
Soft pruning includes making only small cuts if at all
possible, leaving some extra wood at the cut site to allow the wood to dry out and maximising the opportunity for sap to flow around the plant.
When might you get sunburn or raisined grapes (from extreme heat)?
Excessive leaf removal in hot dry years
What are the average yields of Bordeaux in hectolitres per hectare?
Explain the now left behind practise of producing super low yields in the right bank, Why was it a bad thing for the region if the wines showed the usually sought after high concentration and intensity?
50hL/ha
This resulted in super-concentrated wines that could often be jammy or fatiguing. Moreover, the sense of place, which is a hallmark of fine Bordeaux, is obscured by excessive concentration that robs the wine of any nuance
Regarding hand harvesting:
Harvesting teams are hired for a long period and expect some days of paid idleness should the harvest be interrupted by ___.
Large teams of workers (above 100) are hired by the big estates. Many properties hire workers from other EU countries and board the workers throughout harvest, further adding to the ___.
rain.
cost.
In some parts of the Region, Such as Northern Medoc machine harvesting is a necessity.
Why is this?
as it is a two-hour drive rom Bordeaux there a economic need for machine harvesting is a result as the workers do not want to travel there.
Reasons someone might Machine Harvest in Bordeaux
- Economic Neccessity
- Fungal disease pressure
- if rain or storms are forecast
also, the ease and quick timing if machine harvesting is a huge benefit.
