Synonym: Tanat, Tannat Gris, Tannat Noir Male, Moustrou, Madiron.


Commonly mistaken for: Mansec


Origin: French Variety, very probably from Basque origins, from the zone of Madiron. Its name most probably derives from the elevated level of tannins of the fruit. This variety has become widespread in the viticultural world to be blended into aging wines.  It performs a similar role as Petit Verdot in a blended red but is higher yielding when grown in a warm climate area.  Tannat is most commonly used in the wines of Uraguay.


Agronomic and environmental aspects: Very vigorous vine that demands expanded growing area and longer pruning. Because of its late budding it escapes the spring frosts.


Diseases, pests and disorders: It shows particular sensitivity to mites and the mealy bug, slightly sensitive to botrytis.



Growing Tip: expanded, cottony, of white/amber colour with reddish edges.   

Leaf: of large dimensions, pentagonal, orbicular, 3-lobed or 5-lobed. Has a closed or slightly open petiolar sinus, superior side sinuses shaped like an open U-V, while inferior are hardly present. The upper surface is intense green, leathery and bubbly.

Bunch: medium-large, compact, lengthened, of cylindrical form with one or two wings.   

Berry: of medium dimensions, spherical or elliptic (because of the pressure within the tight bunch); skin of purplish-black, blue-black colour, covered by waxy bloom.
