France

France – the home of Bordeaux, Burgundy, Loire and Champagne – is arguably the world's most important wine-producing country. For centuries, it has produced wine in greater quantity – and of reportedly greater quality – than any other nation. Wine is ingrained in French culture at almost every level of society; it is the drink of both the elite and the common people, and a key symbol in Roman Catholicism, France's majority religion.

The diversity of French wine is due, in part, to the country's wide range of climates. Champagne, its most northerly region, has one of the coolest climates anywhere in the wine-growing world – in stark contrast to the warm, dry Rhone Valley 350 miles (560km) away in the southeast. Bordeaux, in the southwest, has a maritime climate heavily influenced by the Atlantic ocean to its west and the various rivers that wind their way between its vineyards. Far from any oceanic influence, eastern regions such as Burgundy and Alsace have a continental climate, with warm, dry summers and cold winters. In France's deep south, Provence and Languedoc-Roussillon enjoy a definitively Mediterranean climate, characterized by hot summers and relatively mild winters.

France's appellation system was created in the early 20th century and has since been imitated in many other countries. This complex system of laws ultimately defines each wine region and its boundaries and imposes strict rules around winemaking practices. Protecting the names of French wines and guaranteeing the quality and provenance of the products themselves are its key objectives. No other country has developed its appellation system to such an extent; as of 2012, there were more than 450 controlled appellations under the AOC titles and a further 150 Vin de Pays/IGP titles.

Bordeaux

Bordeaux, in the southwest of France, needs little introduction as one of the world's most famous, prestigious and prolific wine regions. The majority of Bordeaux wines (nearly 90 percent of production volume) are the dry, medium- and full-bodied red Bordeaux Blends that established its reputation.

The finest (and most expensive) of these are the wines from the great châteaux of the Haut-Médoc and the Right Bank appellations Saint-Émilion and Pomerol. The former is focused (at the top level) on Cabernet Sauvignon, the latter pair on on Merlot.

The legendary reds are complemented by high-quality white wines based on Sémillon and Sauvignon Blanc. These range from dry whites to challenge the best from the Burgundy region (Pessac-Léognan is particularly renowned) to the sweet, botrytized nectars of Sauternes.

While Bordeaux is well regarded for wines produced within specific districts or communes, many of its wines fall under other, broader appellations. These include AOC Bordeaux, Bordeaux Supérieur and the sparkling-specific Crémant de Bordeaux. The Bordeaux Rouge appellation accounts for more than one-third of all production.

The official Bordeaux viticultural region stretches for 130 kilometers (80 miles) inland from the Atlantic coast. 111,000 hectares (274,000 acres) of vineyards were recorded in 2018, a figure which had remained largely consistent over the previous decade.

Bordeaux Grape Varieties
The "big three" make up 98 percent of all red grape plantings, according to 2020 figures on the official Vins de Bordeaux website:

Merlot, which accounts for 66 percent of all red grape plantings
Cabernet Sauvignon (22.5 percent)
Cabernet Franc (9.5 percent)
Petit Verdot, Malbec and Carmenère (2 percent)
These last three are grapes which have been largely abandoned (the latter almonst entirely) since the 19th Century, as they failed to ripen reliably, though Malbec has a continued role in Saint-Émilion in single-digit percentages as a color enhancer. Climate change and success achieved elsewhere may yet lead to a partial comeback for one or more of them.

Bordeaux's white wines are generally blends of Sémillon, Sauvignon Blanc, and, less often, Muscadelle. Sauvignon Blanc has seen some uplift in recent years given the success of varietal wines from New Zealand and other regions. As of 2020 the figures for permitted white grapes were:

Sémillon (47 percent)
Sauvignon Blanc (45 percent)
Muscadelle (5 percent, dwindling)
Sauvignon Gris, Colombard, Ugni Blanc, Merlot Blanc
