The Zaloščan wine cellar, owned by the family of Anton Slejko, markets its wines under the established brand name of De Adami. The wines carry the name of a venerable monk who lived in the village of Zalošče in the 16th century and who is still very much alive in the stories told among the people.

The cellar got its name from the village of Zalošče, situated at the very heart of the wine-growing Vipava valley. Besides their own grapes, they also buy grapes from five winegrowers that provide the cellar with the surplus of their integrated harvest. They make fourteen varietal still wines and wine types. Their wines are soft, fruity, fresh and easy-drinking, while their vintage wines rank among the top wines in the world. Outstanding reviews given to their wines in Slovenia and abroad are a result of unique winegrowing sites and minimum interference in the process of winegrowing, climatic conditions and the wine-growing soil. Attentive care, love for soil and vines, as well as respect for the wine and tradition are also an important factor contributing to the success of the forth generation of the Slejko family that gives their wines the soul and thus completes their recognizable character.
