How did the Dutch influence the history of Bordeaux?
In the 17th and 18th centuries, Dutch engineers built a system of canals (jalles) to drain the marshy lowlands of the Médoc to make the area more suitable for viticulture.
This revealed fast-draining, gravel soils (including the famous croupes, mounds of warm, gravel soils).
What was the Exposition Universelle de Paris?
- A world exhibition showcasing French industrial and agricultural products as well as fine art.
- First established by Emperor Napoleon III, following a similar event in England.
- The Bordeaux chamber of commerce asked the region’s brokers to compile a classification of wines. This was based as price, and became to be known as the 1855 classification.
What is Bordeaux’s climate classification?
Moderate maritime
How does the Gulf Stream influence Bordeaux’s climate?
Originating from the Gulf of Mexico, the Gulf Stream is a warming influence.
What is the name of the pine forest protecting Bordeaux’s left bank from Atlantic Storms?
The Landes
How does the Landes pine forest influence nearby vineyards?
- The Landes pine forest protects some vineyards on the left bank of Bordeaux from Atlantic storms.
- The estates that fringe the Landes are cooler and thus more marginal than their neighbours to the east (eg Domaine de Chevalier in Léognan).
What is the average annual rainfall in Bordeaux?
950mm
Why does Bordeaux often experience vintage variation?
Variable rainfall year-to-year.
How does excessive rainfall at key moments in Bordeaux’s season affect viticulture?
- Rain at flowering can result in poor fruit set.
- Rain throughout the growing season can result in increased disease pressure.
- Rain at and following véraison can lead to unripe fruit and fungal diseases.
- Rain at harvest can dilute flavours.
How has climate change influenced Bordeaux’s growing season?
More hot and dry summers
How does the climate differ between the left bank and right bank of Bordeaux?
The left bank experiences more of a maritime climate, whereas this is less pronounced in the right bank (slightly more continental).
What are the key climactic hazards that Bordeaux experiences?
- Frosts (especially in years such as 1956, 1991 and 2017).
- Hail, increasingly widespread and sporadic in the last decade

Paulliac and Saint Julien
Outline the soils of Margaux.
Shallower gravel soils with clay, limestone and sand.
What are the key advantages of Bordeaux’s gravel soils?
- Very good drainage; suitable for high rainfall regions such as Bordeaux as vineyards are able to dry out more quickly
- Heat retention: the high content of stones and pebbles absorb heat, aiding ripening.
What is the key disadvantage of Bordeaux’s gravel soils?
In very warm, dry years, vines can suffer drought and water stress due to the soil’s inability to retain water.
Which communes of the Médoc have a higher proportion of clay in their soils?
Saint Estephe and Margaux.
How do the soils of Bordeaux’s left and right banks differ?
The left bank has a higher content of gravel, whereas the dominant soil of the right bank is clay.

Pomerol lies on a gently rising plateau with three seperate terraces formed during the Ice Age.
Lowest terrace Sandy
Middle terrace Gravel > sand and clay.
** Upper terrace** Clay > gravel. Deep blue clay at the highest and eastern-most point.

Guyot; single or double, and to a much lesser extent; cordon trained, spur pruned.
What is ‘soft pruning’?
A treatment against Eutypa Dieback and Esca
Only small cuts are made 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.
What diseases commonly occur in Bordeaux?
- Downey mildew, powdery mildew and botrytis due to high rainfall
- Flavescence Dorée (grape vine yellows).
- Eutypa Dieback and Esca
How might a grower reduce the threat of Eutypa Dieback and Esca?

By using insecticides against leafhoppers (the disease’s vector).
What percentage of Bordeaux’s vineyards are certified organics (or in conversion)?
18%
(as of 2021)
What is an essential step to be taken to prevent fungal disease in Bordeaux?
Leaf removal; intended to improve aeration and deter rot.
It also aids ripening.
Why do some producers remove bunches (or bunch-thin) in Bordeaux?
This was a way to correct vines carrying a high yield, and to improve concentration of flavour.
Less popular now; most prefer to prune short in the winter to control yields.
What is the overall average yield of Bordeaux?
50 hL/ha
Which region is known for ‘plot-by-plot’ winemaking?
Bordeaux; specifically premium estates.
What is ‘plot-by-plot’ winemaking?

Outline the typical options for red wine fermentations in Bordeaux.
- Vessel: Closed vats (stainless steel, wood, concrete) with pump-overs and temperature control

- Duration: 5-7 days for wines intended for early consumption, 14-30 days for wines intended for bottle age.
