Background and Aims
In recent years, there has been significant growth in the popularity, and therefore sales, of Moscato in Australia. The aim of this study was to determine the sensory and quality variation amongst Australian Moscato wines, as well as consumer acceptance of different styles of Moscato.
Methods and Results
The sensory profile of 24 Australian Moscato wines was determined by descriptive analysis using a trained panel, while quality ratings were determined by an expert panel of sparkling winemakers and wine show judges. Statistical analysis of sensory attribute ratings facilitated selection of a subset of Moscato wines, comprising three white and three pink wine styles that reflected the sensory variation observed amongst all wines, which were subsequently used in acceptance trials to determine consumer liking.
Conclusions
Considerable diversity was observed amongst the composition and sensory profiles of the Moscato wines studied, with some exhibiting more prominent varietal characters, while others displayed complex, developed notes. Mean hedonic ratings for the subset of Moscato wines ranged from 4.7 to 5.6 (on a 9 cm scale). Segmentation of consumers according to their individual liking scores enabled identification of two consumer clusters with opposing preferences for distinct styles of Moscato.
Significance of the Study
The variation in sensory profiles and quality of Australian Moscato wines has been profiled for the first time and consumer acceptance of different styles of Moscato determined. These results enable industry to make more informed decisions with regard to wine production and marketing, that is, to tailor different styles of Moscato for specific segments of the domestic sparkling wine market.
