The monks of the Tvrdoš Monastery opened a new chapter of the wine making story in monasteries ten years ago. They started working old Vranac vineyards covering 70 hectares of land and planted new 60 hectares of vineyards in Popovo polje. The monastery has two wine cellars. Vranac ages in hundred years old oak barrels in an old cellar from the XV century and only ten meters away, next to the bank of the river of Trebišnjica, a new cellar has been build and equipped with the modern technology. Cellars of the Tvrdoš Monastery apply traditions of monastery viticulture and Herzegovian climate, producing wines made of autochthonous and international varieties of grapes in the cellar from the XV century. Žilavka, vranac, chardonnay, cabernet sauvignon and traditional monastery varieties are combined using ancient and modern technologies. Tvrdoš wines have been awarded silver medals for its quality.
