DO Catalunya is the DO covering wines made in Catalonia outside the areas protected by the other DOs. It embodies a traditional way of making wine, blending wines from various Catalan wine-growing counties.

It is Catalonia's smallest DO and the closest to Barcelona. It has a typical soil, sauló, which gives its wines special characteristics: its very good drainage makes the vine roots grow very deep and lends them minerality.

In Catalonia, DO Cava extends across various parts of Penedès, Anoia, Baix Llobregat, Camp de Tarragona, Conca de Barberà, Costers del Segre and Empordà.
