The Grading Process
Green coffee is graded by Q-certified professionals — trained tasters who evaluate samples brewed to a standardised recipe. They assess ten attributes: fragrance, aroma, flavour, aftertaste, acidity, body, balance, uniformity, clean cup, and sweetness. Coffee that meets high standards across all attributes earns a specialty-grade classification.
Commodity coffee — the kind in supermarket own-brand bags and instant coffee — does not pass this grading. Specialty-grade coffee has no primary defects and minimal secondary defects. It has distinct, positive character. Every coffee we stock at blend.ie is specialty-grade.
What Gets Evaluated
Fragrance and aroma (the dry grounds and the wet cup), flavour (the overall taste impression), aftertaste (what lingers after swallowing), acidity (the brightness and quality of acidity, not harshness), body (the weight and texture in the mouth), balance (how the attributes work together), uniformity (consistency across multiple cups), clean cup (absence of off-flavours), and sweetness (natural sweetness without additives).
Defects disqualify coffee from specialty status. These include ferment, mould, phenol, or rubber — signs of poor harvesting or processing. The grading process exists to catch these before coffee reaches the roaster.
Why It Matters
Specialty-grade coffee tastes noticeably different from commodity coffee. You can distinguish the origin — it might have a clear chocolate or nut profile. Better lots have distinct, positive character: clear fruit notes, defined acidity, a clean finish. The best coffees are striking. The acidity might be complex. The aroma might be floral or fruity in ways that are immediately obvious.
The practical takeaway: buy specialty-grade coffee from a roaster who can tell you about the origin. If they cannot, they are buying without tasting. Grading is not everything — roast level, freshness, and brew method matter enormously — but it tells you the starting quality of the raw material before any of that.
