Within the Jerez region the term "bodega" is used not only to refer to the warehouses where sherry wines are stored during their production and ageing, but is also used to describe those companies which are dedicated to the activity.
Those bodega firms belonging to the Denomination of Origin are recorded in the different official registers kept by Consejo Regulador according to the stage of the sherry production and ageing process in which they intervene:
A register also exists for what are known as the "Processing Bodegas" in which those facilities used for pressing grapes and those where they are transformed into base wine during the harvest are registered each year. Given the nature of the process these Processing Bodegas are facilities which are only used for a few months of the year.
Often they are wine-producing facilities belonging to sherry firms which in turn are to be found in the Ageing or Production Register. On other occasions they are independent pressing-houses which sell base wine to the sherry firms.
