What You Need to Cup Coffee According to SCAA Standards

If you’ve ever wondered what it actually takes to properly cup coffee the way professional tasters do—according to the Specialty Coffee Association of America—you’re not alone. There’s a precise set of rules governing roast level, timing, grind size, water temperature, and even how long you wait after roasting. These aren’t just suggestions—they define the baseline for consistent, repeatable coffee evaluation around the globe.

To meet SCAA cupping standards, start with a medium roast (equivalent to SCAA Roast Color #55), roast for 8–12 minutes without scorching, cool quickly, and cup within 24 hours but no sooner than 8 hours post-roast. That’s the essential framework.

SCAA Cupping Roast Profile: Why Medium Matters

The SCAA specifies a medium roast, which you can identify using the SCAA Roast Color Tile #55. This roast level ensures you taste the bean’s inherent characteristics without being overshadowed by roast flavors. The roast duration should be tightly controlled: 8 to 12 minutes is ideal. Avoid burning or creating ‘tipping’ (charred spots), which introduce off-flavors and invalidate the cupping profile. This roast stage highlights origin traits while remaining light enough for accurate sensory evaluation.

Timing Is Critical: From Roast to Cup

Roasted coffee needs time to degas but shouldn’t sit too long before evaluation. Once roasted, the beans must rest for at least 8 hours—but no more than 24 hours—before cupping. That window ensures the coffee is stable yet still freshly expressive. For example, if you finish roasting at 12:00 noon, you have until 8:00 p.m. the same evening to begin cupping, with a hard deadline of 12:00 noon the following day. Don’t wait longer: freshness and balance decline sharply after 24 hours.

Grinding and Sample Prep: Precision in Every Step

Cupping starts with the grind. Grind your samples within 15 minutes of cupping if possible. If you must wait, cover the grounds and don’t exceed 30 minutes total. Aim for 70% to 75% of the grinds to pass through a US Standard #20 sieve—that’s your target grind size. Prepare six cups of equal weight per sample: use one for rinsing the cupping spoon, and the remaining five for consistent evaluation across multiple cups. Always prepare five cups per sample to assess uniformity—key for spotting processing or roast flaws.

The Gold Standard Cupping Recipe: Coffee, Water, Time

The SCAA defines the optimal cupping brew as follows: 8.25 grams of ground coffee + 150 milliliters of water heated to 93°C (200°F). Let it steep for 3 to 5 minutes, with 4 minutes as the standard. If your cup volume differs—for instance, 180 milliliters—adjust the dose accordingly (about 9.9 or 10 grams). After brewing, break the crust (the layer of grounds floating on top), skim off any residue, and let the coffee cool to approximately 71°C (160°F) before beginning the sensory evaluation by slurping.

Why These Numbers? Science Behind the Specs

Every number in the SCAA cupping protocol is the result of research and field testing. The 8.25g dose, 150ml water, and 93°C extraction parameters are calibrated to produce balanced, repeatable extractions across a wide range of coffees. Adjustments to coffee dose are allowed based on actual cup volume, but the 1:17 to 1:18 brew ratio range stays consistent. Timing the steep and controlling cooling temperature ensure the aromatics and flavors develop fully without over-extraction or bitterness.

Frequently Asked Questions

What roast level does SCAA recommend for cupping?

SCAA recommends a medium roast, specifically aligned with SCAA Roast Color Tile #55. This roast level is light enough to highlight the coffee’s origin qualities without heavy roast interference.

How long after roasting can you cup coffee?

You should cup coffee between 8 and 24 hours after roasting. For example, coffee roasted at noon can be cupped from 8:00 p.m. the same day until noon the next day.

What is the proper grind size for SCAA cupping?

The grind should allow 70% to 75% of particles to pass through a US Standard #20 sieve. This equates to a medium-coarse grind similar to what you’d use for French press, but slightly finer.

How much coffee and water are used in a standard SCAA cupping session?

The standard is 8.25 grams of coffee and 150 milliliters (about 5.1 fluid ounces) of water per cup. Adjust the coffee dose proportionally if your cup volume differs, such as using around 10 grams for 180 ml.

What temperature should cupping water be?

Use water heated to 93°C (200°F). Allow the brewed coffee to cool to about 71°C (160°F) before cupping and evaluating by aroma and taste.

How many cups per coffee sample should you prepare for cupping?

Prepare five cups per sample for consistent evaluation. An additional cup is used for spoon rinsing, making it six total cups per coffee evaluated.
