However, the ability to predict wine style from tasting grapes is unverified and the relationship between the sensory characters of grapes and wine is poorly understood. The objective of the study was to investigate the sensory properties of Cabernet Sauvignon grapes and the corresponding wines, and to determine the relationships between the two data sets. Grapes were harvested between 23–25 Brix from eight locations across the state of South Australia over two vintages and vinified using a standardized protocol. A total of 25 samples from across the eight locations were harvested for each vintage. The grapes and wines were evaluated by a trained descriptive analysis sensory panel. Grapes were evaluated using the berry sensory assessment (BSA) methodology previously described in the literature and grapes and wines were measured for their basic chemical parameters. Samples were consistently discriminated by chemical and sensory properties within the grape and wine data sets across vintages. Five sensory attributes of wine were consistently modelled with moderate to high regressions using BSA attributes and berry chemical measures. Finding berry sensory attributes that consistently relate to wine style and profile remains challenging. The contribution of basic chemical measures including Brix, anthocyanins, and chroma of grape homogenates were reliable contributors to wine sensory attributes for both vintages. ER -
