It corresponds to the ratio between production and surface area of cultivated vineyards. It is usually expressed in hectolitres (100 liters) per hectare (10,000m2).<\/span><\/p>\n

In 2019, the average yield per hectare is 57 hectolitres per hectare, or 7,600 bottles per hectare. But the different vineyards are heterogeneous: the average over 20 years at Yquem (Sauternes, Bordeaux) is 10 hectoliters per hectare (with a maximum authorized of 25 hectoliters per hectare), while in the old Languedoc vineyards we reached up to 120 hectoliters per hectare.<\/span><\/p>\n

In most cases, the more bunches a vine has, the more energy it divides up to ripen them. In fact, high-yielding vines produce grapes that are less mature and less concentrated in sugar, flavor and acidity. Wines are therefore less rich and flavors are more diluted. As a result, many renowned winemakers focus on low yields in order to obtain the best quality grapes possible.<\/span><\/p>\n

What does yield depend on?<\/h2>\n


\nYield is determined by grape variety, soil, age of vines, viticultural practices, year (weather conditions), type of harvest and pressing. Yield potential can be estimated before the harvest using certain data. We can take into account the density at which the vines are planted, the number of eyes left when pruning (the load), the number of bunches per eye (fertility) and the average weight of a bunch.<\/span><\/p>\n

Yield limits in France<\/h2>\n


\nIn France, wine yields are monitored and limited. Of course, this limit depends on the region and appellation, and each appellation has its own specifications specifying authorized yields. If the vineyard fails to comply with the specifications, the wine it produces is downgraded to a less prestigious appellation.<\/span><\/p>\n

Thus, we have the following performance limitations:<\/span><\/p>\n
