    Sounds interesting. I wonder how the choice of participants for the sensory tests impacts the lack of differences observed.

    A total of 100 untrained coffee consumers participated in the study (consuming coffee at least once per week)

      I think they’re more concerned with whether the average consumer has a negative opinion. A coffee snob will be picky regardless.
