Discover the grape variety: Etraire de la Dui

Etraire de la Dui is a black grape variety, originating from the department of Isère. It is so similar to the Persian that many people have difficulty differentiating between them. This resemblance has earned it the nickname "gros persan". This grape variety is now in danger of extinction. It is only cultivated on 10ha. The leaves of the Dui are large and have convex teeth. Its bunches and berries are generally large. A vigorous variety, it is quite productive and prefers a short pruning. This plant appreciates deep, clay-limestone soils. With an average budburst, it reaches maturity in the second half of the year. It fears winter frosts and is susceptible to shattering, especially when fully ripe. On the other hand, it defends itself well against powdery mildew and grey rot. This variety produces concentrated, colorful and tannic wines. Some of them are astringent when the grape variety is too ripe.
