Name for a liquid measure and unit of weight that was used in Spain and Portugal, especially for oil, wine and honey. In some Latin American countries, the arroba is still a very common measure of weight or quantity for staple foods such as flour, sugar, maize, beans and rice as well as coca leaves. The volume was/is somewhat different per country and also locally. The values are between 10 and 15 l or kg.
In Spain, arroba is still used to some extent for a certain quantity of grapes that are wedged into a harvest basket during the grape harvest. When grapes are harvested for the production of sherry, this is understood to mean a picking basket with 11.5 kg of grapes. A carretada (a wagonload of grapes) consists of 62 arrobas. See also under units of measurement.
I have great respect for the scope and quality of the wein.plus encyclopaedia. It is a unique place to go for crisp, sound information on terms from the world of wine.
