How to Cup and Test Coffee Like a Professional

Ever wonder how professional coffee tasters evaluate a new coffee bean—without bias, without fancy gear, and with repeatable results? Whether you’re a home enthusiast or a roaster-in-training, understanding how experts assess coffee reveals far more than just 'good' or 'bad.' This is how they break it down, step by methodical step.

To taste and evaluate a coffee bean thoroughly, pros typically test it in two ways: first through steep extraction (like a simplified pour-over or cupping), then as an espresso. Each method highlights different characteristics, and both are done under controlled conditions to isolate the coffee’s inherent traits.

Why Test Coffee in Two Ways?

Coffee evaluation serves one goal: to understand the bean’s qualities for research or selection. Steep extraction gives a clear, unprocessed view of the coffee’s intrinsic flavors, while espresso amplifies every detail—good or bad—making it easier to assess a bean’s full range.

Steep Extraction: Your Coffee’s ‘Sashimi’ View

Think of steep extraction as the sashimi version of coffee: direct, minimal processing, and highly revealing. This method minimizes variables like brew technique, focusing purely on the coffee itself. It’s also equipment-light and portable—ideal for both lab and field tasting.

For steep tests, I use an Abid Dripper fitted with a Hario MCD3SV metal filter. This combo is reliable, easy to use, and delivers consistent results. When traveling, I switch to a French press or standard cupping setup.

Here’s my standard setup with the Abid Dripper and metal filter:

• Coffee dose: Two level European coffee spoons (approximately 14–16g)
• Grind size: Medium
• Water volume: 250ml
• Water temperature: 200°F (≈93.3°C)
• Steeping time: 2 minutes
• Agitation: Stir three times during steeping
• Serving vessel: White ceramic cup

While brewing, I record detailed observations on:

• a) Bean appearance, roast level (pre-grind Agtron), dry bean aroma
• b) Dry fragrance, color of ground coffee (post-grind Agtron)
• c) Wet aroma (just after water contact)
• d) Brew color
• e) Full cupping notes (flavor, acidity, body, etc.)

Espresso Testing: The Flavor Amplifier

Espresso is a magnifying glass for coffee character. Every strength, weakness, nuance, and defect becomes obvious—which is why it’s invaluable for deep evaluation. But espresso is also highly sensitive to variables, so control is critical.

To stabilize the test environment, I rely on a Synesso Cyncra machine with ±0.1°F temperature precision, paired with a Mazzer Robur grinder using a conical burr. For consistent puck prep, I use a fixed-pressure tamper (Press Point Espresso Tamper) instead of manual pressing.

My standard espresso test protocol includes:

• Water temperature: 200°F or 203.5°F for medium-light roasts (both tested); 197°F for dark roasts (adjusted as needed)
• Dose: 17g in a Synesso NPF (naked portafilter)
• Filter basket: Double shot basket
• Extraction time: ~30 seconds
• Yield: 25–60ml, adjusted per coffee behavior
• Preparation: Fresh water is drawn into all boilers before each test session

I may tweak dose or basket size depending on the coffee’s response and available time. The key is consistency across every variable except the coffee itself.

When and How to Taste for Best Results

Tasting isn’t just about method—it’s about timing and setup. To get the clearest read on a coffee:

• Time of day: Always taste in the morning, preferably during daylight hours
• Freshness: Avoid coffees less than three days post-roast. For espresso blends, wait one week (dark roast) to two weeks (medium-light roast) post-roast
• Cup color: Only use white cups to accurately judge color and crema
• Repetition: Never judge a coffee on one cupping or shot. Re-test the same beans multiple times over days or weeks

Frequently Asked Questions

What’s the best way to evaluate a new coffee bean?

Evaluate using both steep extraction and espresso. Steep brewing (like a simplified pour-over) shows the coffee’s natural profile with minimal variables, while espresso amplifies all characteristics, making strengths and flaws more visible. Both methods should be done under controlled conditions.

What grind size and dose do you use for steep testing?

For steep extraction, use a medium grind with two level European coffee spoons (about 14–16g) of coffee, extracted with 250ml of water at 200°F for 2 minutes. Stir three times during the brew.

What’s your espresso test temperature for light and dark roasts?

For medium-light roasts, test at both 200°F and 203.5°F. For dark roasts, start at 197°F and adjust based on results. These benchmarks help highlight the roast profile’s impact on flavor.

Why shouldn’t you taste coffee right after roasting?

Always let coffee rest post-roast. Avoid tasting beans less than three days old. For espresso blends, wait one week (for dark roasts) or two weeks (for medium-light roasts) to allow gases to dissipate and flavors to stabilize.

Does cup color matter when tasting coffee?

Yes. Always use a white cup. Colored cups can distort your perception of coffee color, crema, and even flavor contrast, leading to inaccurate assessments.

How many times should you taste the same coffee?

Never rely on a single cupping or shot. Always re-taste the same coffee multiple times over several days or weeks to account for variables like freshness, mood, and preparation consistency.
