Experimental set- up. On the left, the table is laid out with glasses and the questionnaires are shown. On the right, the first question in the response booklet is demonstrated. For this question, participants had to choose which of the seven coloured cups best matched the smell/nose of the sparkling wine. For half of the participants, the left-right ordering of the colours was reversed (that is, the deep red glass appeared on the left of the score sheet).
