Situated on the southwestern facing slope of the Zabrada mountains between the small villages of Trstenik and Podobuče, it is a highly regarded area for growing the autochthonous Croatian red wine grape, Plavac Mali.

This attribute, in addition to the level of sunlight (2800 hours annually), 45 degree slope, and weather make for ideal red wines growing conditions which are planted from sea level up to 300 m.[1] The wines derived from this area are eligible for a "stamp of geographic origin" if they meet a series of strict requirements[2] and can reach upwards of 17.6% alcohol.

Also, at Potomje is the entrance to a one lane tunnel through the mountain that winemakers paid to build in 1973 in order to transport grapes directly.

This replaced the old system of using donkeys to carry harvested grapes over the 400 m high pass of the mountain.

[1] Notable producers of Dingač region wines include: Matuško, Matković, Bura-Mokalo, Miloš, Kiridžija, Benmosché, Indijan[5] and Bartulović among others.
