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.
