Trebinje, Bosnia-Herzegovina. Along the banks of the Trebišnjica river, in the Petrovo and Popovo Polje plains, vines grow surrounded by stony and lunar mountains. These vines give life to žilavka and vranac, two wines that have made the history and success of enology in Eastern Herzegovina. An age-old and fragile treasure of tastes, now promoted and safeguarded by the local Slow Food convivium
