Methods A non-trained panel of 100 consumers evaluated eight organic herbal teas: lemon verbena (Aloysia triphylla), white peppermint (Mentha x piperita officinalis), lemon thyme (Thymus x citriodorus), lemongrass (Cymbopogon citratus), chamomile (Chamaemelum nobile), lemon balm (Melissa officinalis), globe amaranth (Gomphrena globose) and tutsan (Hypericum androsaemum), using a CATA ballot with the 39 Essence Profile emotion terms. After the tasting test, two focus groups (n=6) were performed in order to evaluate the applicability of the questionnaire, namely the terms that were missing or those that did not match herbal teas.

The emotion terms ‘happy’, ‘steady, ‘mild’ and ‘tender’ were removed because were considered to be very similar to other emotion terms in the questionnaire. The participants of the focus group added the emotions ‘indifferent’, ‘afraid’, ‘confused’ and ‘relaxed’.
