Terroir - Influences of Viticulture and Winemaking

Influences of Viticulture and Winemaking

Many decisions during the growing and winemaking process can either lessen or increase the expression of terroir in the wine. These include decisions about pruning, irrigation and selecting time of harvest. At the winery the use of oak, cultured or ambient yeast, length of maceration and time in contact with lees, temperature during fermentation as well as processes like micro-oxygenation, chaptalization, clarification with fining agents, and reverse osmosis all have the potential to either reduce or emphasize some aspect derived from the terroir. Winemakers can work between the extremes of producing wine that is terroir-driven and focussed on purely expressing the unique aspects of a region's terroir, or winemaking that is done without any consideration given to terroir. Furthermore, aspects of terroir such as climate and soil type may be considered when deciding such things as which grape variety to plant if the goal is to make good wine rather than terroir-driven wine.

The importance of these influences depends on the culture of a particular wine region. In France, particularly Burgundy, there is the belief that the role of a winemaker is to bring out the expression of a wine's terroir. The French word for winemaker, vigneron, is more aptly translated as "wine-grower" rather than "winemaker". The belief that the terroir is the dominant influence in the wine is the basis behind French wine labels emphasizing the region, vineyard, or AOC more prominently than the varietal of grape, and often more prominently than the producer.
