Macabeo
Very common grape in northern Spain and, as Maccabéo or Maccabeu, in the Languedoc and Roussillon. It is known as Viura in Rioja, where it is very much the dominant variety for white wines. Its vaguely floral character develops at full ripeness but it is often picked earlier to retain acidity. As Macabeo it is an important ingredient in Cava. See this article.
