Spain has the largest number of vineyards in the world. However, it does not have the highest production. That would be Italy first, with France as a close second. The reason for this is the density of the vineyards, and the yield per hectare. Spain has a wine-making tradition since 3000-4000 BCE, with a flourishing trade established through Cadiz as early as 1100 BCE.
The country of Spain is home to a great number of indigenous grapes, over 400. The most famous are Airén, Tempranillo, Garnacha, Monastrell, Albarino, and Verdejo. Apart from a prominent red and white wine production, it is also known for its cultivation of sparkling wine (cava) and reinforced wine (sherry).
