What is the climate in Bordeaux
moderate maritime
what is a contributing factor to cooling influences in Bordeaux?
Atlantic Ocean which lies just west of the region
Describe climate in best years for Bordeaux
gentle heat throughout the growing season, sufficient rainfall to promote growth and ripening, fine relatively dry and warm early autumns allow for steady and complete ripenings - resulting in balanced tannins, sugar and acidity
what is the left bank protected by?
extensive pine forests called the Landes which protect from Atlantic storms
How to estates that fringe on the Landes compare to other sites in Bordeaux?
they are cooler and more marginal than their neighbors to the east
Explain how the Landes impact the northern Medoc
much less of an influence and it is more open to the maritime influence making it a cooler climate
Describe rainfall in Bordeaux
variable but an average of 950mm a year but with marked variation from year to year and sometimes within the year when it falls
When is excessive rainfall important in vintage variation in Bordeaux
rain at flowering can result in poor fruit set
rain throughout the growing season can result in increased disease pressure
rain at harvest can dilute flavors
rain at and following Verasian can lead to unripe fruit and fungal disease
What has climate change led to in Bordeaux?
hot, dry summers, with insufficient rainfall
What happened to Bordeaux in 2003
it was a hot dry year which led to low acidity and lacking balance.
what can hot dry weather lead to in wines in Bordeaux?
wines with low acidity, high alcohol and a lack of balance
Where is the maritime influence less pronounced in Bordeaux?
easterly Right Bank regions such as Libournas (Saint Emillion, Pomerol, and appellations that surround them)
In what years were crops desimated by frost in Bordeaux?
1956, 1991, and 2017
Where are the most prestigious wines found in the Medoc?
close to the Gironde estuary which has moderating influence on the climate and often protects those vines from frost
What happens to vines that are slightly to the west of the most prestigious vineyards in Medoc because the vines are not protected by moderating influences
they can be devastated by frost
What has hail been like in Bordeaux over the past decade
more widespread and destructive
What is considered the Left Bank
Medoc to the north of the city and Graves to the south
What soil does the Left bank have?
gravel and stony that were carried to the region by floodwaters from the Pyrenees and the Massif Central thousands of year ago
What is the gravel mixed with on the left bank?
clay and sand
Where are the top estates on the left bank planted
on gravel mounds called croupes
How does gravel differ from clay? why is this beneficial
it drains well so even after storms and showers (which the left bank is prone) the roots dry out and grapes can continue to ripen
What years have the vines been subject to drought stress in Bordeaux due to extreme heat
2003 2005
What area of Bordeaux has seen very hot summers and because of their roots only being a metre deep have suffered drought stress?
Pomerol
How is gravel helpful in Bordeaux?
drains well and heat retention
How does gravel help to retain heat in Bordeaux?
after a warm summer day the pebbles and stones retain the warm and continue gradually to release it upwards onto the vines facilitating slow ripening.
Where are pockets of clay found in Bordeaux?
On the left bank especially Saint Estephe, but the wines from these soils while robust and characterful have not achieved the same acclaim as those grown on gravel
what type of soil is found more on the right bank?
more clay and there are significant patches of gravel soil in certain sectors such as Libiournais
Why is Merlot a dominant varietal on the right bank?
due to clay soil with patches of gravel in certain sectors
How does Merlot do well on the right bank
it ripens fully in almost all vintages, accumulates more sugar and thus less alcohol tha Cab Sauv and Cab franc.
Where are the best wines from the right bank seem to come from?
limestone plateau or gravel section that borders Pomerol
What does the early budding of Merlot make it vulnerable to?
spring frosts
What type of ripening grape is Merlot? how is this an advantage
mid ripening - which allows grapes to be picked before early autumn rain
What is Merlot susceptible to?
coulure, drought and most botrytis bunch rot which makes sorting necessary to maintain quality
What is an important benefit to Merlot in Bordeaux?
it can fuller ripen in cooler years in comparison to the later ripening Cab Suav
What is the dominant variety of the right bank and the cooler northern region of Medoc, which has clay soils with high clay content?
Merlot
What does Merlot ripening in cooler soils and water holding capacity of clay help to produce?
the larger berry size that Merlot is known for
What is the higher sugar levels that Merlot can reach help to produce
higher alcohol levels than either of the Cabernets
What does Merlot contribute as a varietal
med to pronounced intensity fruit (strawberry, plum with herbaceous notes in cooler years, cooked blackberry, black plum in hotter years)
med tannins
med to high alcohol
What type of variety is Cabernet Sauvignon in terms of budding?
late budding - which gives it some protection from spring frosts
Describe Cabernet Sauvignon as a grape
small berried, think skinned, high tannin content resulting in wines with high tannins
what is Cabernet Sauvignon prone to?
fungal diseases, (esp powdery mildew and trunk diseases, Eutypa and Esca)
What type of soils does Cab Sauv need to grown in

pronounced violet, black currant, black cherry, and menthol or herbaceous flavors
med alcohol
high acidity
high tannins
What characteristics does Cab Sauv display when it struggles to ripen in Bordeaux?
high acidity
unripe tannins
little fruit
Why is Cab Sauv often blended with Cab franc and Merlot?
due to their earlier ripening

Cahors
What variety ripens even later than Cab Sauv
Petit Verdot
What is Petit Verdot prone to?
spring frosts, failure to ripen in cool climates and to rain around harvest
Where does Petit Verdot do best in Bordeaux?
warmer regions of the Medoc
How much of Petit Verdot is typically used in a Bordeaux Blend?

General SAT for Semillon
low intensity apple, lemon and if under ripe grassy, flavors
med body, med alcohol,
med to med + acidity

strong affinity to vanilla and sweet spice flavors from new french oak
What does Semillon contribute to botrytis affected sweet Bordeaux wines?
pronounced honey, dried fruit (lemon, peach) character and a waxy texture
Is Semillon able to age?
yes it is prized for it developing toast and honey notes in contrast with Sauvignon Blanc that can hold those flavors and not evolVe
What does Sauvignon Blanc contribute to Bordeaux wines
grassy, gooseberry fruit, high acidity to dry blends and sweet botrytis affected wines
What type of sites does Muscadelle need to be planted on and why?
well exposed sites as it is prone to botrytis bunch rot

closely spaced vines at 10,000 vines per hectare, vines being planted 1 meter a[art with one meter between the rows
the traditional vine plantings in Bordeaux are suitable for what type of soils?
infertile soils resulting in moderate vigor
How does planting close together in Bordeaux result in higher costs?
more plants, more tresilling have to be bought, specialised over the row tractors bought and more time is needed for training, ploughing, and sparying
What is a benefit of close planting in Bordeaux?
makes best use of expensive vineyard land
What density are less prestigious appellations planted in Bordeaux? Give an example
lower density
basic Bordeaux AOC is planted at 3-4,000 vines per ha

head trained replacement cane pruned where canes are trained along wires
Which bank uses Double Guyot training? Single Guyot training?
double Guyot = Left Bank
single guyot = Right Bank
Which vine training is rare in Bordeaux but some prestigious estates favor it due to reducing yields naturally and giving better aeration to bunches
cordon trained spur pruned
Why is canopy management important in Bordeaux?
due to its moderate damp climate canopy management helps to reduce the incidence of downy mildew, powdery mildew and botrytis bunch rot
What is the purpose of leaf removal in the summer in Bordeaux?
to improve aeration and deter rot and expose grapes to ultraviolent light to aid in ripening
What can compound problems in Bordeaux in regards to when an attack of mildew is followed by rain
tractors may have difficulty entering the vineyards to spray and the rain washes away the treatments
What two diseases cause problems in Bordeaux in regards to the rotting the vine from the inside?
Eutypa dieback and Esca
What is a new treatment in Bordeaux which is becoming increasingly popular in Europe and is farily successful
soft pruning
what is soft pruning
making small cuts if at all possible leaving some extra wood at the cut site to allow the wood to dry out and maximize the opportunity for sap to flow around the plant
How can Flavescence doree be contained? What controversy surrounds it
using insecticides
makes organic and biodynamic producers uneasy due to use of synthetic insecticides
Where can leave removal take place in Bordeaux?
on either one or both sides of the row
Why must one be careful when removing leaves from rows in the Bordeaux vineyards?
leaves protect the bunches from sunburn and extreme heat
When is it less risky to remove leaves in Bordeaux vineyards?
late in the season when extreme heat is less likely and the bunches can benefit from the better aeration
When did it become approved practice in Bordeaux to remove bunches either by hand or machine? what is a much more common practice today?
20 years ago
allowing vines to find their natural balance avoiding corrective measures unless there is no alternative
What is removing bunches in a vineyard meant to do in Bordeaux?
correct vines carrying a high yield and to improve concentration of flavor
How have yields done in Bordeaux in the last 2 decades?
decreased - they now average 50 hl/ha and the wines have benefited
Where is there a fashion for exaggeratedly low yields in Bordeaux? what is the outcome of this?
right bank
super concentrated wines that often can be jammy or fatiguing
Explain how harvest used to be random process in Bordeaux
teams would be hired to arrive for a defined period based on an informed guess as to when the grapes would ripen causing in each vintage some grapes would be picked over ripe, some under ripe and some just right.
Explain how the harvest process has changed today in Bordeaux?
teams are hired for longer periods of time, and expect some days of paid idleness, should the harvest be interrupted by rain. Many workers hired from other EU countries and are boarded throughout the harvest
Why are some vineyards in Medoc harvested by machine
it is difficult to find hired help to travel up to a 2 hour drive to the vineyards
also some machine harvest to collect grapes quickly if fungal pressure is high or weather forecasts storms or rain
Which method gives greater quality control at harvest: hand or machine harvesting?
hand - top estates routinely pick by hand
How are grapes from inexpensive wines be sorted in Bordeaux
they are not routinely sorted
How are grapes for high quality wines sorted in Bordeaux
first by those harvesting by hand as they pick, by hand on a moving or vibrating belt, or in very well funded facilities by optical sorting.
what have many properties in Bordeaux moved to in order to produce high quality wines
plot by plot winemaking, picking individual plots for optimum ripeness and then making separate small lots of wine with those grapes
in terms of red wine making in Bordeaux what type of vessel does it take place in?
closed vats with pump overs
typically wood, stainless steel, and concrete
What type of yeasts are used for red wine making in Bordeaux
mostly cultured yeasts due to its reliability
What temp and post-fermentation maceration on the skins is used for red winemaking in Bordeaux?
depends on the style wine being made
mid range temp and short fermentation (5–7 days) is used for wines made for early drinking, made to preserve fruit flavor and to limit extractions of tannins
mid-range to warm temp and a total of 14-30 days on the skins may be used for wines intended to be aged for many years in bottle
When are maceration times reduced in Bordeaux?
in poor vintages if fruit is not fully ripe
What happens after fermentation for red wines in Bordeaux?
wine is drained off and remaining skins are pressed
How are skins pressed for red wines in Bordeaux
pneumatic presses or in modern vertical or hydraulic presses - due to gentle extraction
What happens after grapes are pressed in Bordeaux
It is transferred to 225 litre barrels (barriques) and the winemaker will decide later what proportion of press wine the final wine will include
Where does malolactic conversion take place and why?
either in tanks or barrels as some argue there is better integration of wine and wood
When are top-quality wines initially tasted in Bordeaux?
in the spring following the harvest
Why will some producers inncoulate during malolactic conversion in Bordeaux
due to needing to ensure rapid completion of the process due to the spring tastings
What might producers do to encourage an efficient conversion in Bordeaux?
heat their cellars
What vessels are used for simpler wines to age in Bordeaux
stainless steel, concrete vats or large vats
How long do simpler wines age in Bordeaux?
4-6 months
What may be used for simpler wines to give oak flavor effect in Bordeaux?
oak chips
What vessel is used for high quality wines in Bordeaux?
French oak barriques
most common is a mix of new and 1 yr old and 2 yr old barriques
though very prestigious properties will use up to 100% new oak
Why do winemakers choose a range of cooperages for barrel making in Bordeaux?
to add complexity and the level of toast typically medium to medium plus
HOw long are red wines matured in Bordeaux
18-24 months depending on the quality of the wine - some need longer
How often are wines racked in Bordeaux?
every 3 months (by tradition) although some winemakers don’t disturb the wine at all
What are the two approaches to blending in Bordeaux?
those opting to present for En Primeur in the spring blend over the winter resulting in final product
minority of winemakers blend a few months before bottling when the blending team can assess the evolution of each variety and each lot before making final decisions
