Term for too high earnings; look there.
Name for the yield of grapes or grapes in the vintage, mostly expressed in hectoliters grape or wine per hectare or kilogram of grapes per hectare. Overseas is too tons / acre common. This is also called wine law Target, expressed as maximum yield in hectoliters per hectare, used for certain wine quality grades and may vary widely depending on the country, wine-growing region, individual locations or even specific wines. In terms of grapevine density, there has been an extreme reduction in the last two millennia. The Romans still recommended 50,000 vines per hectare; this excluded from the outset a mechanical processing of the vineyard. In the middle of the 19th century, the average density was still 20,000 vines per hectare, with yields of at most 40 hectoliters per hectare. Today, the vines are set at a distance of 1.5 to 2 meters (different for each country and wine-growing region, as well as depending on regional requirements).
In general, it is common to plant an average of 5,000 vines per hectare (see below training system ). In the rough average yields a vine for low-yielding quality wine 1.5 to 2.5 kg of grapes, this results in 1.5 to 2 bottles of wine, each 0.75 l. For specialties, or predicates such as Beerenauslese. Trockenbeerenauslese or Eiswein, it is much less. At the grape varieties cultivated in Germany and Austria one can average about 55 to 75 liters at normal maturity of 100 kilograms of grapes must expect. The yield and quality of grapes in the vineyard are controlled by the winemaker through various measures throughout the year, including among others pruning and foliage care, such as thin out (Green reading) and grapes division or. grapes break,
The yield is calculated using the following formula: average number of grapes per stick x average weight of grapes in kg x number of heads per ha gives the yield in kg / ha. A more precise formula, taking specific values into account, is available from the website "Service Centers Rural Areas Rhineland-Palatinate": (Bleed [Eyes / St.] X Extraction Rate [%] x Average Grape Number / Shoot x Average Grape Weight...
