Carignan is an ancient blue-skinned grape varietal, thought to be indigenous to the Aragon region of Spain. However, today it is most commonly associated with the fine wines of southern France, and has been grown in many countries around the world which have the warm and dry conditions it requires to thrive. Carignan is recognized as being quite a sensitive vine, highly susceptible to all kinds of rot and mildew, although producing excellent results when given the right conditions and handled correctly. Its high tannin levels and acidity make the Carignan grapes very astringent, and as such, they are often used as a blending grape to give body to other, lesser bodied varietals. Despite this, with careful treatment, Carignan can produce superb single varietal wines packed full of character and unique attributes. Ever since the Phoenicians and Romans brought their knowledge of vine cultivation to Spanish soils, the country's culture has grown alongside wine production, with wine being a vital part of Spanish identity and Spanish traditions. Each region of Spain has a wine quite distinct from the others, and it is produced by smallholders and families as much as it is by large companies and established wineries. From the relatively mild and lush regions of La Rioja to the arid plateaus that surround Madrid, grapes are grown in abundance for the now booming Spanish wine industry, and new laws and regulations have recently been put in place to keep the country's standards high. By combining traditional practices with modern technology, Spanish wineries are continuing to produce distinctive wines of great character, flavor and aroma, with the focus shifting in recent decades to quality over quantity.
