The lower end of the scale is below specialty grade. Evaluation Procedure Samples should first be visually inspected for roast color. This is marked on the sheet and may be used as a reference during the rating of specific flavor attributes. After infusing with water, the crust is left unbroken for at least 3 minutes but not more than 5 minutes.
Breaking of the crust is done by stirring 3 times, then allowing the foam to run down the back of the spoon while gently sniffing. The liquor is aspirated into the mouth in such a way as to cover as much area as possible, especially the tongue and upper palate.
Because the retro nasal vapors are at their maximum intensity at these elevated temperatures, Flavor and Aftertaste are rated at this point. For these attributes, the cupper makes a judgment on each individual cup, awarding 2 points per cup per attribute 10 points maximum score.
Step 4 - Scoring After evaluating the samples, all the scores are added as describe in the "Scoring" section below and the Final Score is written in the upper right hand box. Individual Component Scores The attribute score is recorded in the appropriate box on the cupping form. On some of the positive attributes, there are two tick-mark scales. One can evaluate this at three distinct steps in the cupping process: 1 sniffing the grounds placed into the cup before pouring water onto the coffee; 2 sniffing the aromas released while breaking the crust; and 3 sniffing the aromas released as the coffee steeps.
Specific aromas can be noted under "qualities" and the intensity of the dry, break, and wet aroma aspects noted on the 5-point vertical scales. It is a combined impression of all the gustatory taste bud sensations and retro-nasal aromas that go from the mouth to nose. The score given for Flavor should account for the intensity, quality and complexity of its combined taste and aroma, experienced when the coffee is slurped into the mouth vigorously so as to involve the entire palate in the evaluation.
Aftertaste Aftertaste is defined as the length of positive flavor taste and aroma qualities emanating from the back of the palate and remaining after the coffee is expectorated or swallowed. If the aftertaste were short or unpleasant, a lower score would be given. Acidity Acidity is often described as "brightness" when favorable or "sour" when unfavorable.
Acidity that is overly intense or dominating may be unpleasant, however, and excessive acidity may not be appropriate to the flavor profile of the sample. Coffees expected to be high in Acidity, such as a Kenya coffee, or coffees expected to be low in Acidity, such as a Sumatra coffee, can receive equally high preference scores although their intensity rankings will be quite different.
Body The quality of Body is based upon the tactile feeling of the liquid in the mouth, especially as perceived between the tongue and roof of the mouth. Most samples with heavy Body may also receive a high score in terms of quality due to the presence of brew colloids and sucrose. Some samples with lighter Body may also have a pleasant feeling in the mouth, however. Coffees expected to be high in Body, such as a Sumatra coffee, or coffees expected to be low in Body, such as a Mexican coffee, can receive equally high preference scores although their intensity rankings will be quite different.
Balance How all the various aspects of Flavor, Aftertaste, Acidity and Body of the sample work together and complement or contrast to each other is Balance. If the sample is lacking in certain aroma or taste attributes or if some attributes are overpowering, the Balance score would be reduced. Sweetness Sweetness refers to a pleasing fullness of flavor as well as any obvious sweetness and its perception is the result of the presence of certain carbohydrates. The opposite of sweetness in this context is sour, astringency or "green" flavors.
This quality may not be directly perceived as in sucrose-laden products such as soft drinks, but will affect other flavor attributes. Clean Cup Clean Cup refers to a lack of interfering negative impressions from first ingestion to final aftertaste, a "transparency" of cup.
In evaluating this attribute, notice the total flavor experience from the time of the initial ingestion to final swallowing or expectoration. Any non-coffee like tastes or aromas will disqualify an individual cup. Uniformity Uniformity refers to consistency of flavor of the different cups of the sample tasted. If the cups taste different, the rating of this aspect would not be as high. Overall The "overall" scoring aspect is meant to reflect the holistically integrated rating of the sample as perceived by the individual panelist.
A sample with many highly pleasant aspects, but not quite "measuring up" would receive a lower rating.
A coffee that met expectations as to its character and reflected particular origin flavor qualities would receive a high score. An exemplary example of preferred characteristics not fully reflected in the individual score of the individual attributes might receive an even higher score.
This is the step where the panelists make their personal appraisal. Defects Defects are negative or poor flavors that detract from the quality of the coffee.
These are classified in 2 ways. A taint is an off-flavor that is noticeable, but not overwhelming, usually found in the aromatic aspects. A "taint" is given a "2" in intensity. A fault is an off-flavor, usually found in the taste aspects, that is either overwhelming or renders the sample unpalatable and is given an intensity rating of "4". The defect must first be classified as a taint or a fault , then described "sour," "rubbery," "ferment," "phenolic" for example and the description written down.
The number of cups in which the defect was found is then noted, and the intensity of the defect is recorded as either a 2 or 4. The defect score is multiplied and subtracted from the total score according to directions on the cupping form. Final Scoring The Final Score is calculated by first summing the individual scores given for each of the primary attributes in the box marked "Total Score. Total Score Quality Classification.
