Very old measure of area (0.25 hectare) already used by the Romans, corresponding to an area of arable land that could be ploughed in one day with one yoke (team) of oxen. Presumably, however, this also applied to perde, but in earlier times oxen were mainly used for agricultural work. The term is derived from the Latin jugerum (iugerum), which corresponded to a quarter of a hectare (2,500 m²). Other terms are juchart, juck, jück, or Tagewerk. Until the end of the 19th century, the fathom was used as the standard measure; 1,600 square fathoms resulted in one yoke. In Austria it is still used today, here a yoke is equivalent to 5,755 m² (0.57 ha); a dash is half a yoke with 2,744 m² and a metzen is a third of a yoke with 1,918 m². Other sizes are found in Hanover with 0.655, in Oldenburg with 0.45 to 0.56, in Switzerland with 0.36 and in Hungary with 0.43 hectares. In terms of meaning and size, the old land measures of acre and acre, as well as the Anglo-American acre, are quite similar. The name "Joch" is also found in the names of individual sites, especially in Germany; for example, Jochhöhschlößchen. See also under area measurements, hollow measurements and units of measurement.
In the past, you needed a wealth of encyclopaedias and specialist literature to keep up to date in your vinophile professional life. Today, Wine lexicon from wein.plus is one of my best helpers and can rightly be called the "bible of wine knowledge".
