 Carignano
is a red grapevine present in all the areas in the Western
Mediterranean where viticulture is practised, and it is therefore difficult
to identify from where it arrived in the island of Sant’Antioco and
the nearby area of Sulcis, to which its diffusion is Iimited. It could
have been introduced by the Phoenicians, the founders of Sulcis, the ruins
of which are still visible on the island of Sant’Antioco, yet it
could also have been introduced in the Aragonese period, as the dialect
term for this grapevine is “Axina di Spagna”. This grapevine
resists well to salt winds and crittogam; it is prolific and does not require
particular soil or climatic conditions: it is interesting to note that
in the vines planted on the fossil dunes present in Sant’Antioco,
it has demonstrated an optimum resistance to phylloxera, so much so that
in old vineyards with treetype vines it is common to find ungrafted vines.
The Carignano grapevine is used to produce red wines, which have a high
alcohol content and a strong colour: reasons for which they are much sought
after, in particular by the French market, as an optimum blending wine;
the DOC wine ‘Carignano di Sulcis’ is obtained from the newly-planted
vineyards, grown with forms different to that of the tree.
