SCAA Cupping Standards for Specialty Coffee

When you’re evaluating coffee quality, especially in a professional or competitive setting, the way you cup matters. Many roasters, buyers, and baristas rely on standardised methods to ensure consistency and fairness. But what exactly does the SCAA — the Specialty Coffee Association of America — require for a proper cupping session? This guide breaks down the essential steps, timings, and measurements so you can cup like the pros.

The SCAA requires cupping coffee roasted to a medium level (reference: SCAA Roast Color Tile No. 55), brewed within 24 hours of roasting but no sooner than 8 hours post-roast, using 8.25g coffee per 150ml water at 93°C, with a 3–5 minute (typically 4-minute) steep.

What Is SCAA Cupping and Why It Matters

SCAA cupping is the standardised method used worldwide to assess green coffee quality, roast consistency, and flavour profiles. It’s the protocol behind cupping tables at origin, in roasteries, and during coffee competitions. By following SCAA guidelines, coffee professionals ensure that every cup is evaluated under the same conditions — making flavour notes, defects, and roast quality truly comparable.

Roast Profile & Timing Requirements

For SCAA cupping, the coffee must be roasted to a medium level. This corresponds to SCAA Roast Color Tile No. 55. The roast duration should be between 8 and 12 minutes — avoid over-roasting until burnt or developing faceted, uneven roast profiles (often called “firing” or “tipping”). After roasting, beans must be cooled quickly and stored in an airtight container away from light and heat. They should rest for at least 8 hours, but cupping must occur within 24 hours of roast completion. For example, if your batch is finished at noon, you have until midnight the same day or noon the next day to cup.

Grinding & Sample Prep

Grind the coffee just before cupping, and begin tasting within 15 minutes of grinding. If you must wait longer than 15 minutes, cover the grounds — but don’t exceed 30 minutes total. Your grind size should allow 70–75% of particles to pass through a US Standard Size 20 sieve. Prepare 6 cups of equal weight for each coffee sample: 1 cup is used to rinse the cupping spoons, leaving 5 for consistent evaluation of uniformity. Arrange these in a standard cupping flight to assess evenness across the batch.

Brew Ratio, Water Temp & Extraction Time

The SCAA-established ideal cupping formula is 8.25 grams of ground coffee to 150 millilitres of water heated to 93°C (200°F). Steep the coffee for 3 to 5 minutes, with 4 minutes being the standard target. Depending on your cup volume — for example, if using 180ml cups — adjust coffee dose accordingly (approx. 9.9g or 10g for 180ml water). Once the steep is complete, break the crust (also called “breaking the cup”) and skim off the foam and grounds. Allow the coffee to cool to around 71°C (160°F) before beginning the sensory evaluation through slurping (or “cuppings”).

Frequently Asked Questions

What roast level does SCAA recommend for cupping?

The SCAA recommends a medium roast, specifically aligned with SCAA Roast Color Tile No. 55. This roast level is neither too light nor too dark, allowing the inherent flavours of the coffee to be clearly evaluated without being masked by roast character.

How long after roasting can you cup coffee according to SCAA?

Cupping should occur no sooner than 8 hours after roasting and no later than 24 hours post-roast. For example, coffee roasted at noon can be cupped anytime between 8:00 PM the same day and 12:00 PM the next day.

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

The SCAA standard is 8.25 grams of ground coffee per 150 millilitres of water. For larger cup volumes, such as 180ml, adjust the dose proportionally (approximately 9.9g or 10g).

What grind size should be used for SCAA cupping?

The grind should be fine enough that 70–75% of the particles pass through a US Standard Size 20 sieve. This typically results in a medium-fine grind akin to what you’d see in commercial cupping setups.

How long should coffee steep during SCAA cupping?

Coffee should steep for 3 to 5 minutes, with 4 minutes being the generally accepted standard duration for balanced extraction.

When is the best time to start cupping after grinding?

You should begin cupping within 15 minutes of grinding. If necessary, you may wait up to 30 minutes, but only if the grounds are covered. Beyond 30 minutes, the coffee’s aromatic and flavour integrity may be compromised.
