Terroir ( in French) was originally a French term in wine and coffee appreciation used to denote the special characteristics of geography that bestowed individuality upon the food product. It can be very loosely translated as "a sense of place" which is embodied in certain qualities, and the sum of the effects that the local environment has had on the manufacture of the product. Terroir is often italicized in English writing to show that it is a French loanword, although many now regard it as a word naturalized into English.
The Terroir-France website asserts that "a 'terroir' is a group of vineyards (or even vines) from the same region, belonging to a specific appellation, and sharing the same type of soil, weather conditions, grapes and wine making savoir-faire, which contribute to give its specific personality to the wine." Some writers include history, tradition, vineyard ownership and other factors.
The contemporary meaning of the term clearly goes beyond mere geography, but at that point disagreement begins. Some assert that terroir is distinct from the characteristics imparted by the plant variety, the vintage and production methods (vinification, etc.), and is the product of a range of local influences that are transmitted into the character of the product.
The question of whether terroir is quantifiable, and the role that terroir plays in producing a "good" wine are matters of some controversy. To complicate the issue even more, some oenophiles use the concept of terroir to refer to wines that are distinctive and unique to their place of origin. In this case, terroir refers not to land but to wine.
The components of terroir may include:
The opposite argument comes from those who do not believe in the concept of terroir. They agree that many aspects of terroir are important to wine quality, such as drainage, aspect, etc., but dispute that the combination creates something truly unique and better. Some argue that perceived local characteristics of wine come predominantly from factors such as local wild yeasts, rather than from factors such as soil and microclimate.
In the middle are those who agree that terroir causes wines to be different, but believe it has no impact on the overall quality of the wine. In their thinking, a Volnay can be a great wine even if it doesn't taste much like other Volnays.
Someone tasting in a number of wines from the premiers crus may perceive them as more concentrated and interesting than the villages wines, and perceive a similar jump from premier cru to grand cru. However, the role of terroir in this can be difficult to determine. One important factor may be expectancies, which is one reason blind tasting is so important. (For example, people expect more expensive wine to have more desirable characteristics than less expensive wine. When given wine that they are falsely told is expensive they virtually always report it as tasting better than the very same wine when they are told that it is inexpensive.) Grand cru wines have lower legal limits on yield, such as a nominal 35 vs 40 hl/ha (350,000 vs 400,000 l/km²), and so on for village and Bourgognes, so they would be expected to be more concentrated. Also, the percentage of new oak tends to increase as the price increases, another difference that is unrelated to terroir. However, despite differences in winemaking, most people do not dispute the effects of terroir. And terroir certainly affects market price.
However, in blind tastings, Premiers Crus often fare poorly against other wines. In the historic Paris Wine Tasting of 1976, the creme de la creme of French wine experts ranked a California wine as the best red wine and three of the four top whites were from California. The results of this and many subsequent blind wine competitions around the world suggest that the importance of terroir can easily be overstated.
For example, in the Ottawa Wine Tasting of 1981, "thirteen wines were involved, and California swept the first five places, defeating Château Lafite-Rothschild, Château Mouton-Rothschild, Château Latour, Château Margaux and Château Haut-Brion, all from the excellent Bordeaux vintage of 1970." These are all Premiers Crus as established by the Bordeaux Wine Official Classification of 1855 and have the greatest terroirs in France.
Wine critic Robert M. Parker, Jr. contends that the terroir-based cru classification system has long victimized consumers. He asserts that mediocre wines have sold for too much thanks to their cru classifications, and that good wines have sold for too little for lack of a ranking. For these reasons, Parker says that cru classifications "should be regarded by both the wine connoisseur and the novice as informational items of historical significance only."
