Fragrance and aroma
The assessment begins before any liquid is tasted. Graders evaluate the fragrance of the dry, freshly ground coffee, then the aroma of the wet grounds once hot water is added.
This first impression reveals the aromatic complexity locked inside the bean and gives an early indication of what the cup will deliver.
Flavour
The combined impression of taste and aroma – the full sensory experience of drinking the coffee.
A high-scoring coffee will have clear, well-developed flavour characteristics: hazelnut and dark chocolate at one end of the spectrum, peach, cherry, or blackcurrant at the other.
Aftertaste
The length and quality of the flavour that lingers after swallowing. A positive aftertaste is clean, sweet, and inviting, the kind that makes you reach for another sip.
Commodity coffees tend to leave a dry, burnt-tasting bitterness that fades unpleasantly.
Acidity
Acidity in speciality coffee is often mistaken for sourness, but it’s actually the liveliness and brightness of the cup.
Good acidity is crisp, sweet, and complex – the green apple quality of malic acid, or the citrus clarity of citric acid. It should feel like a bonus, not a negative.
Body and mouthfeel
The physical weight and texture of the coffee on the tongue – the difference between something light and tea-like, and something rich and almost syrupy.
Q Graders assess whether the body is pleasant, consistent, and suited to the coffee’s origin character.
Balance
This is how well the acidity, sweetness, flavour, and body work together as a whole.
In a well-balanced coffee, no single attribute dominates. Everything is in proportion, and the cup feels continuous from first sip to the last.
Sweetness
Speciality coffee is often naturally sweet – the result of what develops inside a perfectly ripe coffee cherry.
Q Graders look for a clean, honest sweetness: honey, cane sugar, ripe fruit. Nothing added or masked.
Cleanliness
The complete absence of off-flavours, taints, or any negative sensory interference from first sip to the aftertaste.
Any hint of mould, chemical contamination, or poorly managed fermentation eliminates points here immediately
Uniformity
To assess consistency across a harvest, graders cup five separate bowls from the same lot side by side.
If four cups are exceptional but one is flat or defective, the uniformity score drops – a signal that something in the sorting or processing stage wasn’t quite right.
Overall impression
The final rating that allows each taster to express their personal appreciation of the coffee’s character, clarity, and distinction – the qualities that don’t always fit neatly into individual categories but make a truly memorable cup what it is
