Climate in Bordeaux
Moderate Maritime
Maritime climate
- cool-moderate temperatures (moderate in Bx)
- low continentality
(low annual diff between the hottest & coldest months) - evenly spread rainfall throughout the year
Factors influencing reg. cl. in Bordeaux
- Gulf Stream: warming ocean current extends the growing season: spring frosts are rarely a problem and grape ripening can continue well into October
- Atlantic: brings high levels of rainfall & humidity
- Landes forest & coastal sand dunes: lie to the west of the region. Protect from the worst of the Atlantic storms
rain in Bordeaux
Rain falls throughout the year (Maritime) and can
- disrupt flowering & fruit set
- promote rot
- dilute the flavours in the grapes at harvest
–> vintage variation is an important consideration
How can vintage variation in Bx (style & quality) be reduced?
- rejecting unhealthy & unripe grapes
- canopy management
- blend
What changes is done in Bx that have resulted in healthier grapes, decline in use of sprays, and a marked rise in the levels of sugar & flavour development at harvest time?
changes in canopy management techniques
what have the changes in canopy management techniques in Bx resulted in?
(3)
- healthier grapes
- decline in the use of sprays
- marked rise in the levels of sugar & flavour development at harvest time
Sv or blend in Bx?
Almost all red Bx & most Bx whites are produced from a blend of grape varieties
why can it be very risky to rely too heavily on one variety in Bx?
- the variability in the weather, in particular rainfall
flower & ripening times of varieties in Bx
- flower & ripen at different times
–> one bad frost or heavy shower is unlikely to ruin an entire crop - CS: late budding, late ripening
- CF: ?
- Merlot: early budding, mid ripening
(buds & ripens earlier than CS) - PV: ?
- Sémillon: ? budding, mid ripening
- SB: ? budding, early ripening
- Muscadelle: ?

Important Grape Varieties in Bx
(4+3)
- CS
- CF
- Merlot
- PV
- Sémillon
- SB
- Muscadelle
CS in Bx
(where, soil, blend)
- dominates in the Haut-Médoc, also very important in the Bas-Médoc and the Graves
- high stone/gravel content of the soils raises vy temperature –> the only areas where CS can reliably ripen
- prefers well drained warm soils
- 3/4 of the blend in the finest wines
CF in Bx
(where, char., soil)
- widely used in Saint-Émilion and, to a lesser extent, in the Médoc and Graves
- produces wines with less body & tannin than CS
- can have herbaceous or stalky flavours when unripe
- vibrant fruit & floral notes when ripe
- prefers well drained warm soils
Merlot in Bx
(where, soil, type)
- most widely planted variety in Bx
- particularly important in the premium wines of Saint-Émilion & Pomerol
- can successfully grow on the cooler clay soils
- softness
- usually the grape that is perdominant in high volume, inexpensive wines
PV in Bx
- far smaller plantings than CS, CF, Merlot
- ripens fully only in very hot years
- very deep-coloured, tannic wine
- ages slowly
- never plays more than a minor role in a blend
- used mainly to add tannin, colour & some spicy notes
wm practices for red wine in Bx
- wm practices are very varied
- reflection of the style of wine being made & the resources available to the producer
- little agreement over which fermentation vessels produce the best wines: some of the best producers use the traditional oak vats as well as steel or concrete vats to increase their blending options
- most wines are blended in the spring following the vintage, some winemakers prefer to keep their different parcels of wine separate until the end of maturation
- to maintain the quality & style of their top wine:
most leading châteaux now make second & third wines from blends that are not suitable for the grand vin (best wine). Some wine may even be sold off to a négociant. - top-quality red Bx is aged in small oak barriques of 225 litres
- amount of new oak:
–> In the finest châteaux, all the wine may be put into new casks
–> Lesser properties may use a smaller proportion of new casks
–> generic Bx wines are unlikely to see oak at all - constant improvements in the winery have led to riper, fruitier & more concentrated wines even in difficult vintages

Sémillon in Bx
(info, where, blend)
- thin skin
- affinity for noble rot
- most important variety for sweet wines in Bx
- blended with SB in the premium dry white wines of Pessac-Léognan & Graves
- adds body to the blend
SB in Bx
(char., sv vs blend)
- citrus & green fruit aromas
- used increasingly for varietal, dry white wines
- provides high acidity in blended wines, which is particularly necessary for sweet wines
Muscadelle in Bx
- pronounced grapey, floral flavour
- plays an important supporting role in sweet & dry white
- only makes up a small percentage of any blend
wm practices for white wines of Bx
(different styles - different techniques)
1. Lower end
2. Premium dry
3. Great sweet
- made in a range of styles
-
Lower end of the market tend to be
- fresh & fruity
- fermented in temperature controlled, inert vessels
- minimal further ageing
- some show toasty hints of oak -
Premium dry whites from Pessac-Léognan are
- frequently fermented & matured in new oak barrels
- have a richness & nutty flavour overlaying the fruit - The great sweet wines of Bx:
- from fruit that has been infected by noble rot
- best examples are fermented & matured in new oak barrels for anything up to three years
