DO Conca de Barberà has a native and almost exclusive grape variety: trepat. It is an aromatic red grape with little colour.

Priorat's prestige is recognised with the highest quality designation: Qualified Designation of Origin. The area's characteristic soil is llicorella, weathered slate, with very good drainage that encourages the vines to root deeply and produces very low, concentrated yields.

Although there are both white and red grapes, the most representative variety is xarel·lo, which makes intense still or sparkling white wines with character.

Its most characteristic wines are the Garnatxes d’Empordà, sweet wines made from this variety, known locally  as lledoner. Even so, most Empordà wines are dry whites, rosés and reds.

It can be considered Catalonia's oldest DO because, although winemaking at Empúries was almost certainly earlier, Latin authors such as Silius Italicus, Martial and Pliny the Younger praised the wines of Tarraconensis in writing, making it the first local brand with prestige throughout the known world.

DO Terra Alta, one of Catalonia's 7 historic designations of origin, is the southernmost Catalan wine area, located between the river Ebro and the lands of Matarranya. 

DO Montsant is Catalonia's newest (2001). Even so it has a very long history and before 2001 it was part of the Falset sub-zone of DO Tarragona

Since its creation in 1995, the picapoll grape, the DO's characteristic white variety, has gradually been recovered. It has a harsh inland, mid-mountain climate, without the moderating influence of the sea breeze, which favours slow ripening and great concentration in the grapes.

It is the only DO whose territory is spread across eight counties: Pallars Jussà, Pallars Sobirà, Segrià, Urgell, Pla d'Urgell, Garrigues, Noguera and Segarra. And it is made up of 7 sub-zones: Raïmat, Segrià, Pallars, Garrigues, Vall de Riu Corb, Artesa de Segre and Urgell.
