Climate overview
Moderate Maritime Gentle heat in the growing season sufficient rainfall dry and warm autumns leading to excellent balance of tannin, sugar, acidity
Left Bank climate differences
Protected from Atlantic storms by the Landes pine forests
Climatic feature of Listrac
Next to the forest so not as protected from Atlantic influence.
Climatic feature of northern Medoc
Landes forest less of a feature so more exposed to the Atlantic, hence cooler and wetter than southern Medoc and Graves
Average rainfall and when
variable but averages 950 mm
Excessive rain impact on vintage
Flowering poor fruit set
growing season, disease pressure
at and after veraison, fungal diseases
harvest dillutes flavors and can cause berry split and rot
Climate Change
some hot dry summers without adequate rainfall
2003 hot low acidity and lack of balance
more alcoholic wines as growers wait for phenolic ripeness
Right bank climatic influence
Maritime influence less felt
Left Bank Soils
Deposits of gravel and stony soils deposited from the Pyrenees and Massif Central
Can be mixed with clay, sand, minerals
Low gravel mounds (32m) found at the top estates
called croupes
Impact of Gravel Soils
Drain quickly so even after storms, roots dry out quickly so vine can continue ripening
In very hot years (2003 and 2005) can cause water stress
Heat retention that is released at night facilitating ripening
Pomerol soils
Very shallow and in dry years can cause water stress (like 2016)
Other soils on Left Bank
Some pockets of Clay (St. Estephe) but wines do not reach same potential as on gravel
Right Bank soil
Far more clay with some pockets of gravel
Merlot vs Cab Sauv & Franc
Ripens in almost every vintage, more sugar (hence alcohol)
Merlot - budding / ripening
Early budding (spring frosts) Mid ripening (pick before autumn rain)
Merlot hazards
Coulure, Drought, Botrytis bunch rot
Merlot where planted
Most widely planted, dominant on right bank, and cooler northern Medoc where Clay soils are more prevalent
Clay impact on Merlot
Water holding capacity enables large berries associated with Merlot
Merlot characteristics
Medium to pronounced fruit (strawberry, red plum / blackberry black plum)
medium tannin
medium to high alcohol
Cab Sauv budding / ripening
Late budding and late ripening
Cab Sauv hazards
fungal diseases, powdery mildew
Eutypa and Esca
Cab Sauv characteristics
small berries, high tannin
pronounced violet, black currant, black cherry, menthol, herbaceous
medium alcohol, high acid and tannin
Cab Sauv soils
best on the well drained soils of the Medoc
Cab Franc
contributes red fruit, high acid, med tannin
Malbec
mainly replanted with Merlot after frosts of 1956
Petit Verdot basic
Buds early and ripens later than even Cab Sauv
Spring frosts, autumn rains, failure to ripen in cool years
Petit Verdot in blends
Usually less than 5%
deeply colored, spice notes, high tannins
Semillon budding / ripening
mid ripening
Semillon hazards
botrytis bunch rot, noble rot
Semillon characters
light lemon, apple
medium body, alcohol
medium to medium plus acid
Semillon in Bordeaux
In dry whites, Softens Sauv Blanc’s intense flavors and acidity
strong affinity with vanilla and sweet spice of new French oak
In botrytized wines, pronounced honey, dried fruit, waxy texture.
more susceptible to botrytis so top wines have more Sem than Sauv
ageability, toast and honey
Sauv blanc’s flavors don’t evolve with age
Sauv Blanc in Bordeaux
grassy and gooseberry
high acidity
in both dry whites and botrytis
increasing dry white production due to worldwide popularity
