Castello di Rubbia was founded at the end of the 90's as a wine tourism project, continuing the wine-making tradition that begain in the 16th century by the Counts of Egg. The Estate lies in San Michele del Carso in the province of Gorizia. The property contains a vineyard with 13 hectares under vine, producing 60,000 bottles per year, in addition to a historic castle that remains on the estate. It is surrounded by 170 hectares of woodland and 16 kilometres of trenches and underground embrasures from the First World War.

Castello di Rubbia has worked to preserve the traditional native vines of the Carso, such as Terrano, Vitovska and Malvasia. These varietals best represent the distinctive characteristics of the area such as the red soil, a product of a geological phenomenon called Carso, which is rich in iron and lime. In Carso, drought alternates with the local wind, the Bora, to cultivate grapes that produce the best dry, full-bodied wines which have complemented the local gastronomy for centuries.
