Terroir refers to the geographical origin of wines. The landscape factors (topography, parent rock, soil, microbial life, climate, natural vegetation) are coupled with cultural (cultivation history and technology, cultivars rootstock) all together define a terroir. physical can be well visualized by slope profile developed into pedosequence showing regular configuration relevant for wine district. In present study generalized topographic (or catena) GIS spatial model Villány Hills, historical producing region, serves representation characterization terroir types. A survey properties Cabernet Franc grape juice allowed comparison 10 vineyards in Wine District, Southwest Hungary. Five (FAN, NH3, YAN, density glucose + fructose content) have been found moderate linear relationship (0.5 < r2 0.7) Huglin Index (HI) aspect. Aspect, when determined on basis angular distance from South (180°), showed strong correlation (r2 > FAN, sugar primary amino nitrogen (PAN). HI three related parameters content. Elevation slope, however, did not correlate any chemical properties.
