This is certainly the best known but not the only quality DO of Galicia. The white Spanish wine of the Albariño grape is deservedly famous. Galicia has an attractive coastline with large inlets or estuaries here and there known as rías baixas or 'low rivers'. These are slightly reminiscent of the Scandinavian fjords. The rest of the country consists of green valleys in which the coolest and moistest vineyards of Spain are to be found.
There are three different soil types in Rías Baixas: bedrock of granite covered with alluvium, alluvial deposits, or a bedrock of granite with a covering of sand. The average height at which the vineyards are situated is about 1,476 feet (450 metres) . This Spanish wine is mainly white and made from 90% Albariño grapes. These Albariño grapes are said to be a twin of the Riesling. These are said to have been brought to Santiago de Compostella as gifts by German monks. Some wine is also made with Treixadura and/or Loureira Blanca, and also an extremely rare red produced from Brancellao and Cañio.
