WINES OF THE WORLD 🇫🇷 France - Bordeaux Flashcards
Climate of Bordeaux
Moderate maritime, cooling influence by the Atlantic Ocean. The Left Bank is partially protected from Atlantic storms by extensive pine forest (Landes). More maritime influence in the northern Médoc, so cooler than the southern Médoc and Graves. Variable rainfall. Climate change has led to hot and dry summers with insufficient rainfall (drought in 2003). Less maritime influence in the Right Bank. Vineyards close to the Gironde estuary are more protected from frost due to the moderating influence. High vintage variation.
Key elements in the topography of Bordeaux
SW of France, close to the Atlantic Ocean. Traversed by the River Garonne and the River Dordogne, which merge to form the Gironde estuary.
Type of soil in Bordeaux
Deposits of gravel and stony soils in the Left Bank by floodwaters from the Pyrenees and the Massif Central. Gravel mounds not so high (also called croupes), mixed with clay and sand, free-draining soil (risk of drought stress) also heat retention property. Some pockets of clay (Saint-Estèphe) but wines have not the same acclaim as those from gravel. Right Bank is characterised by more clay (some patches of gravel in Libournais).
Croupes
Gravel mounds in the Left Bank of Bordeaux.
Hazards in Bordeaux
Frost can be an issue (1956, 1991, 2017). Risk of hail. Eutypa dieback and Esca, flavescence dorée. Drought can be an issue due to climate change (2003).

Vineyards density in Bordeaux
High density for high-quality vineyards (10,000 vines per ha) and vines are one metre apart with one metre between the rows; the best use of expensive lands. Low density for basic wines (3-4,000 vines per ha).
Training system for the vineyards in Bordeaux
Head-trained, replacement cane-pruned is the common training system. Double Guyot in the Left Bank, single in the Right Bank. Alternatively, cordon-trained, spur-pruned.
Harvest for dry wines in Bordeaux
In the past, teams were hired for a defined period, now for a longer period. Large teams of workers are hired by big estates. Mechanical harvest when difficult to hire workers or for inexpensive wines.
Harvest for sweet wines in Bordeaux
Harvesters need to be able to recognise noble rot in contrast to grey or black rot, more passes for wines made with a high % of botrytised grapes. Usually from September to November.
Key winemaking operations for red wines in Bordeaux
Fermentation in closed vats (wood, stainless steel, concrete) with pump-overs, cultured yeasts, temperature control. Temperatures and time of maceration according to the style and quality. Mid-temperatures of fermentation and short maceration (5-7 days) for early-drinking wines. Warmer temperatures and longer maceration (14-30 days) for wines intended to be aged in the bottle for many years. Shorter maceration if bad vintage. The wine is drained off, the remaining skins are pressed and the pressed wine like the free-run is transferred into barriques. Malo in tanks or barrels (inoculation and heating the cellar).
Key maturation practices for red wines in Bordeaux
Simpler wines stay in stainless steel, concrete vats or large vats for 4-6 months, possibility to add oak chips. French oak barriques for premium wines (18-24 months). Different % of new, one-year-old or two-year-old, also selection of the barrel makers and level of toast (100% new oak for some very prestigious properties). Racking after three months traditionally, some leave the wine undisturbed, or use micro-oxygenation.
When blending for red wines of Bordeaux happens
Two approaches for blending. Most estates blend over the winter, especially those that take part in the en primeur tastings (the outcome is deselection of wines that will end up in the 2nd or 3rd label. Others prefer a few months before bottling because the team know better the evolution of each variety and each lot. Top properties collaborate with a winemaking consultant, that assists them with the blending process.
Grape varieties from Bordeaux used to produce rosé wines
Merlot and Cabernet Sauvignon.
Key winemaking operations for rosé wines in Bordeaux
Traditionally, use of grapes from younger vines or by short maceration and bleeding off method. Now, also direct pressing.
