Bordeaux grape growing?
Moderate maritime climate
1. Moderating influence from Atlantic Ocean, cooling and wet influence.
Bordeaux geology (soil)
Left Bank:
- gravel and stony soils carried to the region by floodwaters from the Pyrenees and the Massif Central
- Depending on their origin, the gravel is mixed with clay and
sand.
- Gravel with sand -> These areas have lighter, freer-draining soils → they warm up quickly → better for Cabernet Sauvignon ripening (Margaux) -> drier and fast draining soils dangerous in dry years (risk of drought stress)
- Gravel with clay -> More common in northern Médoc (e.g. Saint-Estèphe) -> Clay makes soil heavier and cooler, retains more water → can delay ripening a bit → better for Merlot or Cabernet blends.->Vines have more water supply during droughts, which helps in hot years.
- Gravel hold heat, re-radiate it, helping grapes ripen slowly and fully.
- Gravel Drains water quickly
On the Right Bank (where Pomerol is), there is much more clay overall than on the Left Bank. (some gravel near Libournais)
- shallow soils are particularly risk from drought stress which is case Pomerol
- suitable for Merlot, because it thrives on clay soils — it ripens fully and easily, even in cooler years, and builds more sugar/alcohol than Cabernet.
- Best wines come from limestone and gravel section (borders Pomerol)
Merlot characteristics in Bordeaux
Cabernet Sauvignon characteristics in Bordeaux?
Petit Verdot characteristics in Bordeaux?
Semillon characteristics in Bordeaux?
In Bdx dry blend contribute weight and body, soften SBl intense flavour and high acidity.
in sweet wines contribute honey, dried fruit, waxy texture. Top Sauternes wines ->high % of Semillon
Density in Bordeaux, and reasons?
High density as rest of France 10000 vines (Bordeaux AOC 3000-4000 vines).
Reasons: add cost
- more vines
- more trellising need to buy
- tractor need to buy (specialist)
- more time needed for vine training, ploughing and spraying
Why? Best use of expensive vineyard land

Red winemaking in Bordeaux?
Premium wines aged in 225 L French oak - 18-24 months. How barrels made, cooperage, less new oak this days. Wines racked every 3 months, oxygenation (some dont do racking)
Rose Bordeaux winemaking?
Two styles:
Clairet – darker colour, fuller body (more like a very light red)
Rosé – paler colour, lighter style (modern, fresher)
Main grapes: Merlot and Cabernet Sauvignon
How they are made:
Traditional method (for Clairet)
Short maceration and bleeding off (saignée)
Start making red wine → after a few hours, some pink juice is drained off from the skins.
This makes the remaining red wine more concentrated, and the drained juice becomes rosé (Clairet).
Modern method (for pale rosé)
Direct pressing
Red grapes are pressed immediately with almost no skin contact.
Produces a very light-coloured, delicate rosé.
White wine making Bordeaux?
Contemporary style by Denis Douboudieu. and Andre Lurton for white Bdx:
fresher, crisper, aromatic white wines with good balance — not heavy, buttery, or strongly oaked like in the past.
More Sauvignon Blanc → for fresh, aromatic flavours (citrus, herbs)
Some skin contact before pressing → to boost aromas and complexity
Less new oak → keeps wines fresher and lighter, not heavy or too oaky
Cool fermentation in stainless steel → preserves fruity aromas
Often block malolactic conversion → keeps acidity high and crisp
Less bâtonnage (lees stirring) than before → avoids making wines too rich or heavy, especially in warm years
Sweet wine grape growing in Bordeaux?
Level of botrytis in final wines depends on:
1. conditions are correct for spread of noble rot, year to year vary
2. position of estate (proximity to areas where mist forms most regularly)
3. estate able to wait for best time to harvest and risk losing all or part due to adverse weather
4. can pay for workers for multiple passes
Sweet wine winemaking in Bordeaux?
Top quality:
1. barrel fermented (for beter integration of oak and fruit flavours)
2. high% of new oak
3. longer ageing in barrel 18-36 m to gentle oxidation that add complexity
Tell me about left bank regions?
4 most famous:
St Estephe
More clay -> retention of water advantage in dry years, more Merlot plantings (Merlot best in clay)
Coolest region, rustic wines
Cos d’Estournel
Pauillac
More gravel, high % Cab Sauvignon 0> high concentration, great longevity
Ch Lafite, Latour
St-Julien
High % Cab Sauvignon
homogenous gravel soils
stylistically - mid way between Margaux and Pauillac
Margaux
Slightly more Merlot, than Cab S
stony, gravelly soil
further south, grapes ripen 7-10 days earlier than the most Medoc. Some clay. Drainage.
Listrac & Moulis:
Further from river, as a result less moderating influence. And they are located on the Atlantic side of the Medoc, but sheltered from Atlantic by Landes forest. Because of that is slightly cooler here and the soil also.
Both have more clay soils and less gravel soil, indicating more Merlot.
Same AOC wines = early consumption wines.
Graves appellations and grape growing?
Graves AOC - from city Bordeaux to southwards. 85% red.
Graves Superioer AOC - only sweet wines, but higher yields than Sauternes 40 hL/ha (w 58, r 55)
Pessac-Leognan AOC - wishing the city, southern suburbs of city. It has gravel soils and moderating affect like top communes in Medoc.
Known for barrel fermented aged white wines (80%red/20%white)
Max yields 54 for r and w.
White Bordeaux style originates in Pessac-Leognan, describe the style.
Winemaking:
Can direct pressing (maximum freshness) or left on skins up to 24 hours (more aromatic and phenolic complexity).
Mid-priced wines: Left on fine lees 6–12 months → adds weight, complexity, and texture.
Top wines: fermented and aged in barriques, with varying proportion of new oak. (integrate oak flavors with the wine)
Block MLF to retain freshness and acidity.
It used to be common to battonage (stirring fine lees) to enrich wines, but today it gives excessive body producers skip.
Influence
Sauvignon Blanc: Provides aromatic lift, citrus, herbaceous notes, acidity.
Sémillon: Adds body, waxy texture, honeyed character with age, and ability to age in oak.
Oak contributes vanilla, spice, and toast.
Style:
Wines are typically blend of SBl and Semillon
pronounced aromas of gooseberry, lemon and grapefruit with vanilla and clove oak notes
Med (+) body
Med(+) to high acidity
med to high alc
Typically good to outstanding, with premium to super-premium price.
Right bank grape growing?
Right bank characterised by small estates + dominance of Merlot (cool clay soils)
St Emillion and St Million Grand Cru - red wines only
53 hL/ha - St Emillion (6 m)
46 hL/ha - St Emillion GC (20 m)
St Emillion top wines - pronounced red and black plum fruits, vanilla, clove (oak)
Full body, high alc
med(+) - high acidity
med(+) - high tannins
Montagne St Emillion and Lussac-St-Emillion AOC - further away from river Dordogne (less moderating affect)
Pomerol - 80% merlot dominant grape
rest Cab F
max yields 49 hl/ha
Soil in Left Bank Bordeaux?
The soil is also a fundamental factor and with an average of 950 mm of rainfall a year, the soil needs to have good drainage. If the soil gets too wet, there will be a further cooling influence on the vines in an already cool climate. The Left Bank is made up of gravel and stony soils, mixed with clay and sand. Many of the best estates are planted on gravel mounds known as croupes which provide their vineyards with better drainage after showers and storms. The gravel soils also help to retain heat as the pebbles and stones stay warm from the sun during the evening and facilitate ripening, which is particularly beneficial for a late-ripening grape variety like Cabernet Sauvignon.
geography and why St Estephe is cooler ?
The geography here plays a vital role in the quality of the wines. The rivers in the region, the Garonne and the Dordogne, which merge to form the Gironde estuary, divide the vineyard area into different parts. The vineyards on the west of the rivers, known as the ‘Left Bank’ are protected from the Atlantic Ocean’s weather systems by a large pine forest, the Landes. In the northern Médoc, the forest is less of a feature and the landscape is more open to maritime influence. As a result, its climate is cooler and its wines, in general, are less reputed than those of the more southerly Haut-Médoc and Graves.
Explain the density of vines in Bordeaux?
10000 vines per ha:
For example, in Bordeaux, top-quality wine producers tend to plant at a high vine density of 10,000 vines per hectare. In such conditions, where soils are relatively infertile and the level of rainfall is generally sufficient, planting the vines close together can encourage competition between them. This reduces the vigour of the vines and results in a balanced canopy that can ripen moderate crop levels fully while being open enough to reduce the threat of fungal disease.
Right bank Bordeaux grape growing?
The region is in the southwest of France around 45° latitude, at the cooler end of latitudes suitable for grape growing. It has what is classed as a moderate maritime climate due to its close proximity to the Atlantic Ocean.
Warm Gulf Stream, originating in the Gulf of Mexico, is a warming influence across Bordeaux. Plentiful rain to promote growth and ripening. Relatively warm and dry first month of autumn allow steady ripening.
Maritime influence is less prominent in the Right Bank, but remains a factor.
As a result, slightly more continental conditions: warmer summers, cooler winters, and greater vintage variation.
Soil is more clay. Limestone.
More Merlot. It’s best in clay soils, ripen every year even in cooler years. Water holding capacity of soil enable to produce large berry size typical of Merlot. It also reach higher sugar, therefore high potential alcohol.

Bordeaux classifications?
In 2018 revised again. 🥇 The New System Since 2018 (Starting with 2018 vintage)
They returned to a multi-tier classification (like before).
Now each château can be ranked in one of three quality levels:
Cru Bourgeois
Cru Bourgeois Supérieur
Cru Bourgeois Exceptionnel (the highest)
This status lasts for 5 years at a time (not forever, and not just one year like in 2010–2017).
