Executing a precise coffee sensory evaluation requires a rigorous, methodical approach to evaluate coffee’s aromatic and flavor characteristics. Select multiple coffee lots—optimally from distinct growing areas—with differing processing methods—or varying roast profiles. Ensure every sample is freshly roasted and ground immediately before the session to retain delicate fragrance molecules.

Apply the same grind setting—roughly the texture of sea salt—and measure precisely 8.25 grams of coffee per 150 milliliters of water. Opt for پارتاک کافی purified H₂O heated to at a temperature of 194–205°F for balanced solubility.

Assign one bowl per coffee variety, one for each sample. Gently saturate the coffee bed until no dry patches remain. Let it brew for a precise 240 seconds. During this time, a crust of grounds will rise to the top. After four minutes, use a spoon to gently break the crust while noting the bouquet that emerges. The crust break reveals essential olfactory cues, so note the aromatic complexity.

Skim off the surface debris without agitating the grounds at the base. Wait until it reaches a sippable temperature of 60 degrees before sampling. When tasting, slurp loudly to aerate the coffee to distribute it across your entire palate. This technique helps you identify flavor notes, assess acidity levels, determine texture and weight, note sugar-like undertones, and evaluate finish length.

Evaluate all coffees in parallel, maintaining comprehensive notes using SCA-approved flavor lexicon to maintain consistency across sessions.

Reset your sensory perception between tastings with still water and neutral rice cakes. Eliminate ambient scents and distractions to avoid contamination of aroma perception. If possible, conduct the session with a panel of tasters to gain diverse sensory perspectives. Archive your findings in a standardized format so they can be used in procurement decisions.

A disciplined sensory evaluation is more than just tasting coffee—it is revealing the potential hidden in each bean.
