Bordeaux Flashcards
Breakdown of red, white and rosé in Bordeaux?
85% red
10% dry white
1% sweet white
4% rosé
Most widely planted grape in Bordeaux?
Merlot (almost 60% of plantings)
Cabernet Sauvignon what % of plantings in Bordeaux?
20%
(Merlot nearly 60%)
Bordeaux climate
Moderate maritime
Recipe for successful vintage in Bordeaux? Climate etc.
Gentle heat through growing season
Enough rain for growth adn ripening
Fine, dry, warm early autumn
Steady adn complete ripening
Excellent balance of tannins, sugar and acidity
Why is Domaine de Chevalier more marginal climate than others?
Beside the Landes forest
Rainfall in Bordeaux
Variable
950mm a year
Impact of excessive rain at key moments in Bordeaux?
At flowering: poor fruit set
Through season: disease pressure increase
At and after veraison: unripe fruit, fungal
At harvest: dilute flavours
Impact of rain at/after veraison in Bordeaux?
Can lead to unripe fruit, fungal diseases
Hot dry years in Bordeaux do what to grapes?
In extreme cases (eg 2003): low acidity, lack balance
Can also lead to wines being more alcoholic - growers waiting for phenolic ripness
Maritime influence more pronounced on Left or Right Bank Bordeaux?
Left Bank
Less pronounced but still a factor in RB
Examples of frost years in Bordeaux
1956, 1991, 2017, 2021
How does Gironde help in frost years?
Moderating influence on the climate, protecting from forst
Impact on yield of 2017 frost in Bordeaux?
33% less wine made than 10-year average
40% less than 2016
Source of gravels on Left Bank?
Deposits of gravel and stony soils carried by floodwaters from Pyrenees and Massif Central, thousands of years ago
Highest gravel mound in Medoc?
32m, Margaux
Croupes
Gravel mounds in Bordeaux
What drains better, gravel or clay?
Gravel
Even after showers and storms on Left Bank, roots of vines soon dry out
Risk of Medoc gravels in a very hot year?
Eg 2003, 2005
Excellent drainage = risk of drought stress
particularly for shallow soils
What happened in Pomerol in 2016 (re shallow soils)?
Some drought stress
Gravel soils drain well, soil less than a metre deep
What do gravel soils do re: heat?
Retain heat
Pebbles and stones retain warmth after hot summer day, release it upwards to vines gradually = aid slow ripening
Soils in St Estephe?
Gravel
Pockets of clay
Reputation of clay soils in Medoc?
Can make robust and charactful wines
Not as prestigious as gravel
Best soils in Right Bank Bordeaux?
Limestone plateau St Emilion
Gravel in pomerol
lots of clay for the most part
Merlot on clay in Bordeaux: how does it perform?
Very well!
Ripens fully in most vintages
Accumulates more sugar (and thus alcohol) than Cab S/F
Merlot early or late budding?
Early budding
Prone to spring forst
Merlot early or late ripening?
Mid ripening
Grapes picked before autumn rain
Merlot susceptible to what ailments? (and so what?)
Coulure, drought and botrytis bunch rot
= sorting is necessary to maintain quality
all can reduce yields
Key benefit of Merlot in Bordeaux?
It can ripen fully in cooler years
(vs later ripening Cab Sauv)
Benefit of clay’s water-holding capacity for Merlot?

Left Bank: two canes (double Guyot)
Right Bank: one can (single Guyot)
Different Guyot Left vs Right Bank
Left Bank: double Guyot, ie two canes
Right Bank: single Guyot, ie one cane
Second most common way to manage vine in Bdx (after Guyot)
Cordon-trained, spur-pruned
Rare but some estates use it, prestigious
Reduces yields naturally, better aeration
Moderate damp climate in Bordeaux leads to what problems
Downy mildew
Powdery mildew
Botrytis bunch rot
How to fend off mildew pressure with canopy mgmt?
Leaf removal during summer = improve aeration, deter rot
Exposes grapes to UV light = aid ripening
What is soft pruning?
Response to esca and eutypa dieback
Make only small cuts if possible, leave extra wood at cut site, allow wood to dry out
Maximise sap flow
Solution for flavescence dorée in Bordeaux/

max 25hl/ha
below 10hl/ha is common at top estates

True
(Level of botrytis can vary widely from year to year)
