Catarratto

[1] In the Etna DOC, the grape is often blended with Minella bianca and Carricante.

[2] Catarratto exists in different phenotypes characterised by different pruinosity, i.e., different amount of whitish "bloom" on the grape berries.

When this bloom is largely absent, the grapes give a more glossy impression.

They are also registered as two different grape varieties in Italy, but DNA typing has shown them to be identical.

[3] An Italian study published in 2008 using DNA typing (the same study that showed the three Catarrattos to be identical) showed a close genetic relationship between Garganega on the one hand and Catarratto and several other grape varieties on the other hand.
