Sharing borders with Portugal in the south and France in the North, Spain is both culturally and topographically diverse. Spain is cool on the coast particularly due to the surrounding Atlantic Ocean and Mediterranean Sea and is warmer and more arid the more central you travel. There are 138 official wine designations in Spain and has the biggest vineyard surface in the world. There are seven major wine regions which are classed based in their particular microclimates and geography. Broader Spain can be said to include smaller producing regions such as Aragon, Basque Country, Rias Baixas, Murcia and the Canary Islands.
