Bjana is the name for the village of Biljana in the local dialect. Their wines are produced and taken care of on the family estate in the heart of the Goriška Brda wine-growing district, in the pre-alpine world of hills with a strong Mediterranean influence. The wines are matured in a completely renovated manor known as Dorišče, in one of the oldest cellars far and wide. Written sources mention that the manor was built by the counts of Gorizia in the 13th century. Back then it bore the name of Wyglan. The manor is now owned by the family of Miran Sirk. The manor and the surrounding estate were purchased by his great-grandfather Franc Obljubek after World War I. Part of the facility has been arranged to accommodate tourism activities.
