摘要: There are widely divergent opinions on the number of judges required for sensory descriptive analysis (DA) with some authors saying 6 and others up to 15. Yet, there very little data support these numbers. Therefore, from three DA studies between 14 22 trained judges, evaluating 8 30 different red wines in triplicate using 20 descriptors, were re-analyzed randomly selected subsets assessors. The results compared analyses variance, multifactor Tucker-1 analyses. showed variability minimum panelists that gave a stable result, but, general, at least preferably 10 seems sufficient.
