How to Cup Coffee Using the SCAA Method

If you’ve ever wondered how professional coffee tasters evaluate beans—what they sniff for, how they slurp, and why they focus on certain traits—this is your guide. The SCAA (Specialty Coffee Association of America) cupping method is the global standard for assessing green bean quality, roast level, and brewed flavor potential. Here’s how it works, broken down for clarity and precision.

The SCAA cupping protocol evaluates coffee across six key attributes: fragrance, aroma, taste, nose, aftertaste, and body. Each step uses specific measurements—like 10 grams of coffee, 150 ml of water at near-boiling, and a 3–5 minute brew time—to deliver consistent, comparable results.

Step 1: Evaluate Fragrance (Dry Aroma)

Cupping begins before brewing. Grind 10 grams of freshly roasted coffee into 3–5 sample cups. Immediately sniff the dry grounds: the volatile aromatics released—especially sulfur compounds like methyl mercaptan—reveal the coffee’s inherent character. Sweet-smelling grounds often indicate bright, acidic flavors; sharp or pungent notes suggest more intense, potentially harsh profiles. The strength of the fragrance also signals freshness: the shorter the time between roasting and grinding, the more potent the scent. Most aromatic compounds, especially the fragile ones, degrade quickly post-roast.

Step 2: Assess Aroma (Wet Aroma)

Next, pour 150 ml of freshly boiled (near 100°C) filtered water over the ground coffee in each cup. Let it steep for 3–5 minutes, during which a crust (or “cap”) forms on the surface. Break the crust by stirring vigorously with a deep spoon—this releases trapped aromas. Lean in and deeply inhale the vapors rising from the cup. You’ll detect a spectrum of notes, from fruity and floral to nutty and herbal. These wet aromas correlate strongly with the coffee’s origin and processing method, and their intensity reflects how fresh the beans are (measured from roast date to brew time). Packaging that protects against moisture and oxygen also preserves aroma quality.

Step 3 & 4: Taste & Nose (Flavor & Aroma in the Mouth)

Taste and aroma are inseparable in cupping. Use an 8–10 cc silver spoon (for rapid cooling) to take 6–8 cc of brewed coffee. Slurp it forcefully—it aerates the liquid, distributing it evenly across your tongue and sending volatile compounds into your nasal passages via the retronasal route. Focus on the interplay of sweet, salty, sour, and bitter tastes. Temperature affects sensitivity: cooler coffee may mute sweetness but enhance acidity. Hold the coffee in your mouth for 3–5 seconds to identify primary and secondary flavor traits. Simultaneously, note the aromas released in-mouth—this combined assessment defines the coffee’s unique flavor profile. Standard roasts often yield caramelized notes; darker roasts bring out more roasted, sometimes smoky, characteristics.

Step 5: Measure Aftertaste

After swallowing (or spitting out), note the lingering sensations. Swirl the remaining liquid in your mouth, then draw air through your throat to push vapors into your nasal cavity. This reveals the aftertaste: the longer-lasting compounds that define the coffee’s finish. Expect notes ranging from chocolatey sweetness to smoky, woody, or spicy impressions—like cedar, resin, or even clove-like spice. The complexity and persistence of these aftertastes contribute significantly to the coffee’s overall score.

Step 6: Determine Body (Mouthfeel)

Finally, assess the coffee’s body—the tactile sensation of its texture. Glide your tongue along the roof of your mouth to evaluate richness. Oily or silky feels indicate higher fat content; heavier, thicker, or more viscous sensations suggest elevated fiber and protein levels. Together, these traits define the coffee’s “weight” or body—a key factor in its perceived quality and drinking experience.

Frequently Asked Questions

What is the SCAA cupping method?

The SCAA cupping method is a standardized protocol developed by the Specialty Coffee Association of America for evaluating coffee quality. It assesses six attributes—fragrance, aroma, taste, nose, aftertaste, and body—using specific measurements (e.g., 10g coffee, 150ml water, 3–5 min steep) to ensure consistency and comparability across samples.

How much coffee do you use in SCAA cupping?

The SCAA method uses 10 grams of freshly roasted coffee per sample cup. Typically, 3–5 cups are prepared for evaluation to ensure consistency and account for minor variations.

What water temperature is used for SCAA cupping?

The SCAA method specifies using freshly boiled water, close to 100°C (212°F), poured over the ground coffee to start the brewing process.

How long should coffee steep during SCAA cupping?

Coffee grounds should steep for 3–5 minutes after pouring hot water over them. This allows proper extraction and the formation of the crust, which is then broken for aroma evaluation.

Why is slurping important in coffee cupping?

Slurping aerates the coffee, spraying it across the tongue and sending volatile aromas into the nasal cavity via the retronasal passage. This enhances both taste and aroma perception, helping tasters identify a wider range of flavor and fragrance notes.

What does 'body' mean in coffee cupping?

In cupping, 'body' refers to the tactile sensation of the coffee’s texture in the mouth. It’s assessed by how the liquid feels on the roof of the mouth—ranging from light and watery to rich, oily, or thick—and is influenced by the coffee’s fat, fiber, and protein content.
