One of the peculiarities of D.O. Ribeiro is the distinction between the figure of "adega" (bodega), winery and "colleiteiro" (cosechero).The figure of the "colleiteiro" was regulated in 1987 and is contemplated in article 17 of the Regulation on the records of warehouses, in which there is an underregistration of wine cellars. It is understood by "colleiteiro" the wineries that make less than 60,000 liters per year and only from home-grown grapes, without being able to purchase grapes from other winegrowers. For their part, wineries can make wines with grapes from their own vineyards or buy from other winemakers.
