The Robusta version of the Q Grader exam uses scents found in the Le Nez du Vin (wine) set shown here (plus the Le Nez du Café series). Subjects must first match six (6) among nine (9) blind pairs, then identify three (3) specified vials of scents for each of four different groups for the Olfactory Test.
While this Kit includes 54 aromas that are particular to wine, it can hone one's olfactory acuteness as it relates to coffees.
