Costers del Segre is a DO (Denominación de Origen) wine region located in Catalonia, on the north-eastern coast of Spain. The name means 'Banks of the Segre' – a river which originates in the Pyrenees mountain ranges and meets the Ebro River just south of the city of Lleida. Most vineyards sit in the Segre's expansive basin. The DO was created in 1986, but has seen many evolutions since its inception, including new international varieties, adopting modern California winemaking techniques and the creation of sub-regions.

Costers del Segre is Catalonia's most inland wine region and generally speaking, this region is harsh. It's semi-arid, with a climate of extremes. Although its seven fragmented districts do represent a varied mix of soil and climatic conditions. The sub-regions from north to south are Pallars Jussa, Artesa de Segre, Segria, Raimat, Valls del Riucorb, Les Garrigues and Urgell. As a result of these scattered sub-regions, this DO boasts one of the most versatile wine portfolios in the country.
