Spain has a long tradition of winemaking and is one of Europe's largest producers of wine. Freshness and fruit flavors characterize the best Spanish wines rather than oak influences. Rioja and Priorat are the most famous wine regions, known for their red wines made from Tempranillo and Garnacha grapes. Spanish wines also include sparkling cavas from Catalonia, fortified wines similar to Port from Tarragona and Jerez, and everyday table wines across many regions including La Mancha. Classification systems designate wines by region and quality level.
