The method describes the approach for conducting the duo-trio test.
beer, beer-based beverages, non-alcoholic beverages, mineral water
This method can be employed to reveal slight differences between two samples (water, wort, beer), e.g., type and expression of specific attributes or the overall impression.
This method is especially appropriate for a trained tasting panel, if a known product can be employed as a control sample (e.g., beer from a current production run). With an untrained tasting panel and/or unknown samples, one of the pair of samples is used as a control sample. The paired comparison method is better suited for evaluating samples possessing a lingering aftertaste.
