SCAA Cupping Standards for Specialty Coffee Beans

If you’ve ever wondered why professional coffee tasters evaluate beans the same way—or how you can replicate those reliable, consistent cupping sessions at home—understanding the SCAA’s standardized methodology is essential. This isn’t about subjective preference, but repeatable conditions that highlight coffee’s true qualities without bias.

The SCAA requires medium roast coffee (matching color standard 55), roasted between 8 and 12 minutes without scorching or tipping, cooled quickly, and cupped within 24 hours—but no sooner than 8 hours—post-roast.

What Is SCAA Cupping and Why Follow It?

SCAA cupping (from the Specialty Coffee Association of America, now part of the SCA) is the industry standard method for evaluating coffee quality. It removes variables like brew method or personal technique so that professionals can assess aroma, flavor, aftertaste, acidity, body, balance, and sweetness objectively. Following these protocols ensures consistency whether you're cupping in Guangzhou, Seattle, or Addis Ababa.

The Roast: Medium and Precise

For accurate cupping, use a medium roast that aligns with SCAA roast color standard 55. This roast level balances origin characteristics without over- or under-developing the beans. Your roast time must be between 8 and 12 minutes. Avoid scorching or “tipping” (burnt spots on the bean surface). After roasting, cool the beans rapidly and store them in an airtight container away from light and heat. Do not cup until the beans have rested at least 8 hours post-roast—but no later than 24 hours after roasting. For example, beans roasted at noon should be cupped between 8 PM that same day and noon the next day.

Coffee Grinding and Preparation

Grind the coffee just before cupping and begin evaluation within 15 minutes. If delayed, cover the grounds but don’t let them sit longer than 30 minutes. The target grind size must allow 70–75% of particles to pass through a China-standard No. 20 sieve. Prepare six cups of equal weight per sample: one for rinsing the cupping spoon, and five for actual cupping. Arrange five cups per coffee to assess uniformity.

The Cupping Recipe: Coffee, Water, Time

The optimal cupping formula, based on SCAA research, is 8.25 grams of ground coffee per 150 milliliters (5 fluid ounces) of water heated to 93°C (200°F). Allow the coffee to steep for 3 to 5 minutes, typically 4 minutes, for balanced extraction. Adjust the coffee dose proportionally if your cup volume differs: for 180 ml water, use around 9.9 or 10 grams of coffee. After brewing, break the crust with a spoon and skim off the grounds and foam. Let the coffee cool down to approximately 71°C (160°F) before beginning the sensory evaluation by slurping.

Frequently Asked Questions

What roast level does SCAA recommend for cupping?

The SCAA recommends a medium roast that matches color standard 55 on the SCAA roast color chart. This level highlights origin characteristics without excessive bitterness or acidity, ensuring an accurate evaluation of the coffee’s intrinsic qualities.

How long should coffee rest after roasting before cupping?

Coffee should rest for at least 8 hours but no more than 24 hours after roasting before cupping. For example, beans roasted at noon can be cupped any time from 8 PM the same day to noon the next day.

What is the correct coffee-to-water ratio for SCAA cupping?

The SCAA standard ratio is 8.25 grams of ground coffee to 150 milliliters of water. For different cup sizes, adjust proportionally—for instance, 9.9 or 10 grams for 180 ml water—to maintain consistency in extraction.

What grind size should be used for SCAA cupping?

The grind must be fine enough that 70–75% of the particles pass through a China-standard No. 20 sieve. This corresponds to a grind size roughly similar to a pour-over or slightly coarser than espresso, tailored for optimal extraction during the 4-minute steep.

How soon after grinding should you start cupping?

Begin cupping within 15 minutes of grinding. If that’s not possible, cover the grounds and delay no longer than 30 minutes before proceeding with the cupping evaluation.

At what temperature should you taste the coffee during cupping?

Allow the coffee to cool to around 71°C (160°F) before tasting. This temperature is ideal for safely and effectively evaluating aroma, flavor, and mouthfeel through the slurping method.
