Spain’s first region-wide DO was established in 1999 to allow bodegas

in the existing Catalan DOs to blend wines with quality control and

regulated status. Alongside this, as a catch-all denomination, Cataluña

draws in nearly 4,000 hectares of scattered vineyards which were

formerly unclassified within the DO system. These areas are not

allowed to produce wines bottled under another DO name. However,

bodegas registered with the DO may also produce unblended wines

under the original geographically demarcated DOs of which they are

also members.
