An antique and traditional grape growing region is located in the Departments of Lujan de Cuyo and Maipu; a location known as primera zona [1st region] of Argentine wines. Such a name was not given by chance but was adopted by virtue of the prestige acquired by its labels, historically placed among the best productions in the country.

Its privileged location in the south of the city of Mendoza, at perfect heights and on the best land of the province, has considerably collaborated with this aim.

The 1st region in Mendoza has been, together with Valle de Uco, one of the regions that most interest has aroused, and a real attraction for foreign investors, who seek great chances and better wines. RPB S.A. is proud of having two of its three wineries located in the 1st grape growing region.
