Wet Evaluation: Stirring 3 times, then allowing the foam to run down the back of the spoon while gently sniffing.
Step 1: – AT 90-80oC the liquor is aspirated into the mouth in such a way as to cover the tongue and upper palate. Because the retro nasal vapours are at their maximum intensity at these elevated temperatures, Flavour and Aftertaste are rated at this point.
Step 2: – At 80 – 70oC, the Acidity, Body and Balance are rated next. The Balance is the harmony of the tastes and flavours.
Step 3: – At 50-35oC, Sweetness, Uniformity, and Clean Cup are evaluated.
Step 4: – Evaluation of liquor should stop at 21ºC and the Overall score is determined by the cupper and given to the sample as “Cupper’s Points” based on all of the combined attributes.
Tasting and Describing:
