The yield of grapes that will be harvested from a vineyard will depend on several factors including vintage conditions, local wine laws and winemaker's preference. In viticulture, the yield is a measure of the amount of grapes or wine that is produced per unit surface of vineyard, and is therefore a type of crop yield. Two different types of ...
It is because of this reputation that the return on one ton of wine grapes grown in Napa is $3600, while neighboring Sonoma comes in second at $2200 per ton as of 2012. [14] In comparison with other wine grape growing regions in California, Napa ranks second to last in terms of wine grape yield per acre at just over 3 tons grown per acre. [14]
California's own consumption of table production grew from 1980 to 2001 from 1.8 to 3.5 kilograms (4.0 to 7.7 lb) per capita per year. [7] Consumption here and throughout the country is so high that the country remains a net importer despite this state's production, which reached 71,000 short tons (64,000 t) in the 2015 table harvest.

[citation needed] The allowed base yield is 35 hectoliter per hectare (374 US gallons per acre), a minimum planting density of 9,000 vines per hectare and a minimum grape maturity of 11.5% potential alcohol is required. [24] The actual yield over the period 2003-2007 was 26 hectoliters per hectare (278 US gallons per acre). [1]
In the 1970s, yields were reported as surpassing 49 tonnes per hectare (22 short ton/acre), a sharp contrast to the average yields in premium wine regions such as Bordeaux and Napa Valley of 4 to 11 t/ha (2 to 5 short ton/acre). [10] As the Argentine wine industry continues to grow in the 21st century, several related viticultural trends will ...
Yields in Grands Crus must be limited to 45 hectoliters per hectare (3.3 tons per acre) with a 20% allowance for increased yields. [17] There is no official regulation on the use of mechanical harvesting , but most Grand Cru producers prefer hand picking because human pickers tend to be more delicate with the grapes and can distinguish better ...

Older vines with low yields can increase the concentration of phenolic compounds and produce darker, more tannic wines such as those found in the Priorat region of Spain where yields are often around 5-6 hectoliters/hectare (less than half a ton per acre). Yield control is intimately connected with the resulting quality of wine with yields ...
