The amount of coffee sample to be evaluated is determined
according to the brewing standard of Specialty Coffee Association of
America (SCAA). For a standard 100 mL cup of brewed coffee, 4.9 g
of ground coffee is recommended by the SCAA. Therefore, 4.9 g of
each sample of green coffee, roasted coffee, and ground coffee and
100 mL of each sample of brewed coffee were presented to the
panelists in a 414-mL glass snifter covered with a watch glass. The
panelists cleansed their nasal passages between each sample by
breathing through a warm clean cotton washcloth filter.
