Best known for intense, impressive and age-worthy fortified wines, Portugal relies almost exclusively on its many indigenous grape varieties. Bordering Spain to its north and east, and the Atlantic Ocean on its west and south coasts, this is a land where tradition reigns supreme, due to its relative geographical and, for much of the 20th century, political isolation. A long and narrow but small country, Portugal claims considerable diversity in climate and wine styles, with milder weather in the north and significantly more rainfall near the coast.
