The whitish clayey earth of the Ventos and the Castellar Sierras has traditionally been the source of Agost's prosperity - the production of ceramics. Bricks, domestic utensils and typical ivory white botijos (earthenware jugs) have been the main industry of this locality. Today, in addition to the traditional pottery and ceramics, the main source of wealth is the manufacturing of bricks of which there are nine factories in the town. The land has also been very good for the growing of the vines that are present throughout the entire region. Agost is included in the area, has been awarded the title of Denominación de Origen (guarantee of origin) for bagged grapes, and grows the Aledo and Italia varieties.
