What is Terroir: Understanding Wine and Sense of Place

What is terroir? It is the unique combination of natural factors and human influence that gives a wine its distinctive character. For you, as someone acquiring fine wine at auction, understanding terroir is essential for evaluating a wine's quality, aging potential, and long-term value. Jancis Robinson, writing in the Oxford Companion to Wine, describes Burgundy as "the most terroir -conscious of the French wine regions." The region offers a clear example of this concept. The practice of delineating vineyards by their terroir in Burgundy dates back to medieval times. Monasteries played a key role in its development. The Cistercians, for instance, were the first to observe that different vineyard plots consistently yielded different wines. That observation laid the early groundwork for Burgundy's cru naming system and its deep-seated terroir philosophy. This deep connection to place ensures that the wine in your cellar is not just a beverage, but a reflection of its specific origin.

What factors define terroir?

An intricate interplay of natural elements and human decisions shapes terroir. These factors include the specific geography of a vineyard, its climate and the composition of its soil. They also include the viticultural practices that growers employ.

Geography plays a significant role. In Burgundy, for example, the best wines from Grand Cru vineyards are typically grown from the middle and higher parts of the slopes. These locations offer the most exposure to sunshine and superior drainage. Premier Cru wines come from slightly less favorably exposed slopes. More common "village" wines come from the flatter land nearer the villages.

Climate is another critical component. Burgundy's continental climate brings cold winters and hot summers. The weather is often unpredictable, with potential for rain, hail, and frost around harvest time. This variability means that vintages from Burgundy can differ considerably.

Soil conditions are also fundamental. Burgundy is notable for its "400 types of soil." Immense attention is paid to the area of origin and the specific soil type where a wine's grapes are grown. In Bordeaux, however a peculiarity. Any château may use a vineyard parcel that lies within the boundaries of a wine commune. The parcel's inherent quality does not enter into it. This distinction underscores different regional approaches to the importance of soil in defining terroir.

Human factors, or savoir-faire, are the final element. This includes vineyard management and winemaking techniques. The Poor management can result in a significant decline in quality. It cites Chateau Margaux's wines in the 1960s and 1970s as an example of being "far below what's expected of a First Growth." Conversely, Alexis Lichine, a member of the 1960 revision panel, cited Chateau Lynch-Bages as an example of a Fifth Growth. Through good management and by "patiently collecting the best parcels as they come on the market," that estate makes wine worthy of a much higher classification. Yields also impact quality. We cite a study by the Institut National des Appellations d'Origine. It found that yields rose in the appellations contrôlées vineyards of the Côte d'Or. The yearly average went from 29 hectoliters per hectare (hl/ha) between 1951 and 1960 to almost 48 hl/ha between 1982 and 1991. This increase in yields was associated with wines of "less flavor and concentration."

How does terroir influence wine classification?

Terroir's influence on wine classification varies significantly by region. Burgundy and Bordeaux offer contrasting models. The International Standard for the Labelling of Wines by the OIV lists "Appellation of origin or Geographical indication" as compulsory information provided by labelling.

Burgundy's classification system is geographically focused. A specific vineyard or region holds a given classification regardless of the producer. Wine labels reflect this focus: appellations are most prominent. Producers' names often appear in smaller text at the bottom. The region has 100 appellations, classified into four quality categories.

Bordeaux's 1855 classification, in contrast, is producer-driven and awarded to individual châteaux. Emperor Napoleon III requested this system for the 1855 Exposition Universelle de Paris. Brokers ranked wines based on a château's reputation and trading price. The red wines were ranked from first to fifth growths. All but one (Château Haut-Brion from Graves) came from the Médoc region. White wines were limited to sweet varieties from Sauternes and Barsac. Changes to this classification have been rare. Cantemerle was added as a fifth growth in 1856. Château Mouton Rothschild rose from a second growth to a first growth in 1973, after decades of lobbying.

The following table compares the classification approaches in these two prominent French regions:

Feature	Burgundy Classification	Bordeaux 1855 Classification
What is classified	A specific vineyard or region, which holds its classification regardless of the wine's producer	An individual château; any parcel inside the boundaries of the wine commune is eligible to be used by any château, independent of the quality of the parcel itself
Basis of ranking	Geography: the area of origin and which of the region's 400 types of soil the grapes grow in	A château's reputation and trading price, as ranked by wine brokers
Tiers	100 appellations in four quality categories: Bourgogne, village, premier cru and grand cru	Red wines ranked from first to fifth growths; sweet whites of Sauternes and Barsac ranked from superior first growth to second growth
Origin of the system	Cistercian monks were the first to notice that different vineyard plots gave consistently different wines	Emperor Napoleon III requested it for the 1855 Exposition Universelle de Paris
Movement between tiers	Producers are allowed to declassify a wine in steps to a lower-ranked AOC if they wish	Changes have been rare: Cantemerle added as a fifth growth in 1856, Château Mouton Rothschild raised from second growth to first growth in 1973

The Burgundy classification system has four main levels:

• Grand Cru: These wines represent 2% of production, with yields at 35 hl/ha. They are designed for cellaring and typically need a minimum of five to seven years of aging. The best examples keep for over 15 years. The label will only show the vineyard name (e.g., Corton or Montrachet) and the "Grand Cru" term, not the village name.
• Premier Cru: Making up 12% of production, with yields at 45 hl/ha, these wines often require three to five years of aging. Top examples can keep longer. Labels include the village name, "Premier Cru" status, and usually the vineyard name (e.g., "Volnay 1er Cru Les Caillerets").
• Village Appellation: These wines account for 36% of production, with yields at 50 hl/ha. They are generally consumed two to four years after release. Labels display the village name (e.g., "Pommard"), and sometimes the specific single vineyard or climat name.
• Regional Appellation: These wines, such as AOC Bourgogne, can be produced across the entire region or a significantly larger area than a single village. They have yields of 55 hl/ha and are typically intended for immediate consumption, within three years of the vintage date.

How do grape varieties relate to terroir?

Grape varieties are fundamental to how terroir expresses itself in wine. The majority of wine grapes belong to the Vitis vinifera species. Many varieties can grow in diverse locations. Their expression changes dramatically based on the specific terroir.

For instance, Pinot Noir is the dominant red grape in Burgundy's Côte d'Or region. Gamay is prevalent in Beaujolais, which is also part of the Burgundy wine region. Chardonnay is the most common white grape in Burgundy. It produces wines like Chablis and the Côte d'Or whites, which are typically made from 100% Chardonnay grapes. Another white grape, Aligoté, is also found in Burgundy. It tends to produce more acidic, cheaper wines, traditionally used in the Kir drink. Sauvignon Blanc is grown in the Saint Bris appellation of Burgundy.

Cabernet Sauvignon is a cross of Cabernet Franc and Sauvignon Blanc. The variety originated in France in the 17th century. It covered 262,000 hectares globally in 2004. In Bordeaux, its character is profoundly shaped by the Médoc's gravelly soils and maritime climate.

Red Burgundy appellations, from regional to Grand Cru level, generally permit blending up to 15% of white grape varieties like Chardonnay, Pinot Blanc, and Pinot Gris. That practice is "not widely practised today,". This highlights a modern preference for varietal purity, even where historical blending traditions exist.

Why is understanding terroir important for you?

For you, as a fine wine expert and auction buyer, a deep understanding of terroir is crucial. It is what informs your decisions about what to acquire and hold. Terroir directly influences a wine's quality, its potential for development in the cellar, and ultimately, its value in the secondary market.

Recognizing the specific terroir of a wine helps you anticipate its character and aging trajectory. A Grand Cru Burgundy is produced with yields of 35 hl/ha. It is "generally produced in a style meant for cellaring," often requiring "a minimum of five to seven years" and potentially over "15 years" for the best examples. Knowing that lets you gauge its long-term investment potential. Conversely, a regional appellation wine, with yields of 55 hl/ha and typically intended for "immediate consumption, within three years after the vintage date," suggests a different acquisition strategy.

Furthermore, understanding terroir helps you navigate the complexities of wine quality and pricing. British wine critic Jancis Robinson has stated that "price is an extremely unreliable guide" and "what a wine sells for often has more to do with advertising hype and marketing decisions than the quality contained in the bottle,". This perspective suggests that a strong grasp of terroir can enable you to identify undervalued wines. Village-level wines from top producers, Robinson notes, "can be found at lower price points."

The practice of declassification in Burgundy also underscores the importance of terroir knowledge. Producers are permitted to declassify their wine to a lower-ranked AOC if they choose. One example is selling a Grand Cru wine as a Premier Cru. This is often done to maintain the quality and prestige of their top-tier wines, by only including grapes from older vines. The wine from younger vines then sells at a lower price under a lesser appellation. Recognizing these nuances helps you understand the true origin and potential of a bottle, regardless of its label.
