Although it comprises two geologic and geo-morphological units of very different ages, formation and palaeographical evolution--that is the Romanian Plain and the Dobrogea Plateau--, the Danubian-Pontic wine-growing region appears unique because of similar relief and lithologic substratum--since quasi-tabular surfaces covered by a layer of loess are predominant--but mainly because of the resourceful chernozem steppe-silvosteppe soils and climate that benefits largely from the most extensive sun exposure in Romania.
