Abstract What role categorization processes play in
chemosensory expertise and its acquisition? In this paper,
we address this question by exploring the criteria used by
trained and untrained assessors when they categorize beers.
Two experimental factors were manipulated: beer color and
brewery. Participants sorted nine commercial beers coming
in three different colors and from three different breweries.
Participants sorted in two different conditions: in one
condition, participants could see the beers, and in the other
condition, they could not see the beers. We observed that in

and untrained assessors categorized beers similarly. In the
visual condition, assessors sorted beers by color, whereas in
the blind condition, they sorted them by brewery. Overall, our
