Subvarieties and phenotypes
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. ''Catarratto Bianco Comune'' is characterised by a high amount of bloom, while ''Catarratto Bianco Lucido'' has a limited amount of bloom, and is more glossy or 'lucid'. The distinction between the two was first described by the Ampelography, Ampelographic Commission of Palermo in 1883, which gave them their names. They are also registered as two different grape varieties in Italy, but DNA typing has shown them to be identical. Thus, the two phenotypes have resulted from massal selection of vines showing intravarietal variability of vines having been propagated vegetatively (by cuttings) from the same original seedling. A third variety or phenotype, ''Catarratto Bianco Extra Lucido'', with a complete absence of bloom, was selected by B. Pastena in 1971 among Catarratto Bianco Lucido vines. This was also shown to be genetically identical with the other two, as was assumed by its origin.Pedigree
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. It is therefore possible that Garganega is one of the parents of Catarratto, however, since the parents of Garganega have not been identified, the exact nature of the relationship could not be conclusively established.''‘Sangiovese’ and ‘Garganega’ are two key varieties of the Italian grapevine assortment evolution''Synonyms
Catarratto is also known under the synonyms Castellaro, Cataratto Bertolaro, Cataratto Bianco Nostrale, Cataratto Carteddaro, Catarratto Bertolare, Catarratto Bertolaro, Catarratto Bianco Latino, Catarratto Bianco Nostrale Catarratto Carteddaro.References
