Rapid and Cost-Effective Methods for Wine Profiling: CATA/RATA

The objective of this chapter is to underline the main practical and methodological issues encountered when applying CATA or RATA to wine profiling. In the material section, we discuss some important methodological points that might impact the efficiency of the methodologies such as the type of assessors able to perform the task, the selection and presentation of the wines to be described, and the selection and presentation of the terms used to describe the wines. In the method section, we successively detail the CATA or RATA tasting procedures: session organization, instructions to be given to the assessors as well as statistical analysis.
