Trentino's leading wine-making co-operative, Cavit, is on the brink of losing one of its star co-ops.

Cavit, which is the umbrella co-operative for 13 of the region's larger co-ops, has accused LaVis of breaking a commercial agreement by selling bulk wine directly to US wine giant E&J Gallo, which itself is one of Cavit's clients.

Marco Raengo, a spokesman for LaVis, has said that the situation requires legal clarification, adding that the issue was being used to draw attention away from the upcoming election of Cavit's new president and political turmoil within the co-op.

When contacted by just-drinks, Claudio Gambarotto, Cavit's export manager, said: "The issue is quite delicate and we prefer not to comment for now."
