What is "bovale"

Bovale is a name attributed to two Italian wine grape varieties that are known more commonly by their Spanish names. The most widely planted is Bovale Grande ( Carignan/ Mazuelo) which has larger berries, while Bovale Sardo ( Graciano) which has slightly smaller berries and tends to produce a more austere wine is found more rarely. Both are found on the island of Sardinia where they are used mainly for blending.
