France: In general what is the climate?
The climate varies due to the size of the country. Latitude is 42-49, conditions vary markedly between
France: In general, how is the vineyard managed?
With exception of bush vines in the south, virtually all france vineyards are planted at high density with vines trained on trellises. Vines are often trained with cane-replacement pruned Guyot system with vertical shoot positioning.
10% of all vineyard area is certified organic.
France: What is the top 10 of grape varieties grown?
- Merlot
- Ugni Blanc
- Grenache Noir
- Syrah
- Chardonnay
- Cabernet Sauvignon
- Cabernet Franc
- Carignan
- Pinot Noir
- Sauvignon Blanc
France: In general, what can you tell about winemaking?
Chaptalisation was founded in France but lesser used due to warmer climate and better canopy management. Use of maturation in barrels was a long standard in French winemaking. The industry is supported by a large scientific sector devoted to viticulture and vinification.
France: In general, how is wine law and regulation organised?
1935: Institut National des Appellations d’Origine now: Institut National de l’Origine et de la Qualité. It oversees creation of AOC system and also IGP wines.
The AOCs embed a commitment to geographically defined appellations that include rule about methods of productions based on the idea of terroir.
France: In general, what can you tell about wine business?
Average size of vineyard holdings is higher than Spain or Italy (10,5ha). Co-operatives are very important for smaller growers (40%).
Wine consumption per capita is half of the level a century ago. 75% of volume sales are through small and medium-sized local companies or private label, sector is highly fragmented. Largest company is Castel Frères, Carrefour France and ITM enterprices. Export volumes is less than Spain or Italy by volume but still the world leader by value. Also imports, mostly cheaper wines.
Bordeaux: What can you tell in general about Bordeaux?
It is traversed by the river Garonne and the river Dordogne, which merge to form the Gironde. In between the rivers it is known as Entre-Deux-Mers. Left bank and right bank.
90% of plantings are black grapes. Production of AOC wine is 85% red, 10% dry white, 1% sweet white and 4% rose.
Bordeaux: What are the top varieties planted?
- Merlot
- Cabernet Sauvignon
- Cabernet Franc
- Other reds
- Sémillon
- Sauvignon Blanc
- Muscadelle
Bordeaux: What are key developments in the history?
In 17th and 18th century the marshy peninsula of Médoc was drained by Dutch residents in the city of Bordeaux and planted. By mid-18th, Lafite and Margaux were already widely appreciated across Europe and America. Important centre for wine export. Merchants came and brokers they distributed the wines of Bordeaux. This system of distribution is still in place.
1855, Exposition Universelle de Paris, classification of wines based on price, estates of the Médoc plus Haut Brion in Graves were classed into 5 bands, those of Sauternes into three.
Area under vine: 111000 ha, most is for Bordeaux or Bordeaux Supérieur appellations (70%)
Bordeaux: What is the climate of Bordeaux?
The region has a moderate maritime climate. The cool Atlantic Ocean is a cooling influence. In best years, gentle heat, sufficient rainfall and dry and warm autumn allow for steady and complete ripening. Left Bank is partially protected from storms by extensive pine forest (Landes), areas that are less protected by this forest are cooler.
Rainfall is variable, 950mm. Climate change in extreme temperatures does not have the greatest effect on the grapes of Bordeaux other than lack of acidity and thus balance. The rivers can have a moderating influence on frost effects.
Extremes in weather can lead to vintage variation (hail, frost, rain, temperature)
Bordeaux: What are the soils of the Left Bank?
Médoc to the north of the city and Graves to its south, benefits from deposits of gravel and stony soils (from Pyrenees and Massif Central). Gravel is mixed with clay and sand. Croupes are gravel mounds, that’s where the top estates are planted on.
Gravel drains well, so roots dry out soon and grapes can ripen. In extreme heat, there where the soil is shallow (Pomerol), vines can suffer from drought stress.
Gravel also has heat retention, this facilitates slow ripening.
Bordeaux: What are the soils of the Right Bank?
There is more clay in the soil with significant patches of gravel. Merlot is grown here a lot, this is ideally suited to such soils. The best wines come grom grapes grown on the limestone plateau or the gravel section that borders Pomerol
Bordeaux: What are the characteristics of Merlot?
Early budding (spring frost), mid ripening (early harvest). Susceptible to coulure, drought and botrytis. In Bordeaux Merlot can ripen in cooler years. It is the dominant variety on the Right Bank and cooler northern Médoc. It reaches higher sugar levels (higher potential alcohol). It contributes medium to pronounced intensity fruit (strawberry and red plum with herbaceous flavours in cooler years; blackberry, black plum in hot years), medium tannins and medium to high alcohol to the blend.
Bordeaux: What are characteristics of Cabernet Sauvignon?
Late budding (less spring frost). Small berry with thick skin and high tannin. Prone to fungal diseases, especially powdery mildew and Eutypa and Esca. Late ripening (needs warmer soils), making it vulnerable to autumn rains.
It contributes pronounced violet, blackcurrant, black cherry and menthol or herbaceous flavours, medium alcohol and high acidity and tannins to the blend.
In cooler years growers could struggle to ripen resulting in wines with high acidity, unripe tannins and little fruit.
Bordeaux: What are the characteristics of Cabernet Franc?
In Bordeaux as a variety, it contributes red fruit, high acidity and medium tannins to the blend.
Bordeaux: What are the characteristics of Malbec?
In Bordeaux, after the hard frosts of 1956, Malbec was mainly replaced with Merlot, which is easier to grow in Bordeaux.
Bordeaux: What are the characteristics of Petit Verdot?
This variety buds early and ripens late, making it vulnerable to spring frosts, struggle to ripen in cooler years and to rain around harvest. It does best in the warmer parts of the Médoc.
It contributes powerful, deeply coloured wines with spice notes and high tannins. Often less than 5% in blend, nowadays increasingly valued because of warmer climate
Bordeaux: What are the characteristics of Sémillon?
Mid-ripening variety, susceptible to botrytis and noble rot. It has low intensity apple, lemon (and if under ripe: grassy) flavours, a medium body, medium alcohol and medium to medium+ acidity. It contributes low to medium intensity aromas, weight and body, and medium acidity. It softens Sauvignon Blanc. It has strong affinity with vanilla and sweet spice from new oak.
In sweet wines it contributes pronounced honey and dried fruit (lemon, peach) and a waxy texture. Sauternes has high proportion of Sémillon in the blend. It can age well, developing toast and honeyed notes with age.
Bordeaux: What are the characteristics of Sauvignon Blanc?
In Bordeaux, it contributes its grassy and gooseberry fruit and high acidity to dry white blends and to sweet botrytis-affected wines. Also single variety dry SB white wines are made.
Bordeaux: What are the characteristics of Muscadelle?
It needs to be planted on a well-exposed site, as it is very prone to botrytis bunch rot. The vast majority is used in sweet white wines where it contributes flowery and grapey notes.
Bordeaux: What can you tell about vineyard management in plantings?
Top quality is very densely planted, this adds costsas more plants and more trellising have to be bought, specialist tractors bought and more time is needed for vine training, ploughing and spraying. However, this makes the best use of expensive vineyard land.
Often, vines are head-trained, replacement cane-pruned. Left bank: double Guyot, Right bank: single Guyot. Single is cordon-trained, spur-pruned: it reduces yields naturally and gives better aeration.
Bordeaux: What can you tell about vineyard management in disease pressure?
The moderate, damp climate leads careful canopy management to reduce the incidence of downy mildew, powdery mildew and botrytis bunch rot. Important technique is leaf removal to improve aeration and increase exposure to uv-light.
Soft pruning is used to deal with Eutypa dieback and Esca. And insecticides can contain Flavescence dorée, but the use of insecticides is not favoured because of impact on biodiversity.
Bunch-thin was used to correct vines carrying a high yield and to improve concentration, now less used because vines become unbalanced.
Bordeaux: What can you tell about vineyard management in harvesting?
Yield have decreased in the past two decades. This led to exaggeratedly low yields which led to super-concentrated wines that could be jammy or fatiguing.
In harvest nowadays, teams are hired for a longer period with calculated idle days because of rain. This way winegrower can ensure ripe grapes. Because of problems of finding workers, many grapes are picked by machines, especially the grapes intended for high volume inexpensive wines.
Bordeaux: What can you tell in general about winemaking?
Levels of sorting vary according to the value of the wine and the quality of the vintage. Often, especially in high quality wines, plot to plot winemaking is exercised. This way there can be separate lots of wine made which can be blended later. This adds to costs.
