Six coffee questions, answered without the attitude.

Plain-English answers drawn from the Specialty Coffee Association, World Coffee Research and the National Coffee Association. These explain general coffee knowledge, not the scores or identity of any untested coffee. The full searchable answer bank is available below when you need something more specific.

Are tasting notes ingredients added to coffee?

Usually not. Notes such as citrus, cocoa or jasmine describe aromas and flavors a taster perceives in brewed coffee; they are not an ingredient list. Flavored coffees are a separate category. A roaster's tasting notes are its descriptions, not proof that we independently tasted that bag.

Why this matters: A descriptive assessment records perceived sensory characteristics. It is separate from an evaluator's judgment of quality.

What is the difference between washed, natural and honey coffee?

In broad terms, washed coffee is depulped and its mucilage is removed before drying; natural coffee dries inside the whole cherry; honey coffee is depulped but dried with some mucilage remaining. These process labels do not guarantee a particular flavor or a higher score.

Why this matters: Processing choices influence fermentation and drying, but variety, ripeness, handling and roasting also affect the cup.

Is Arabica a coffee variety?

Arabica is a species, Coffea arabica. Bourbon, Typica, and many other named lines are varieties within that species. A variety name can help explain agronomic traits, but it cannot identify a farm or establish that a particular lot tastes a certain way.

Why this matters: Growing environment, plant health and postharvest decisions matter alongside genetics.

Is dark roast stronger than light roast?

Dark roast can taste more bitter or intensely roasted, but that does not by itself mean it contains more caffeine. Roast color labels are not uniform across companies. Compare the same coffee brewed at the same dose before attributing flavor or strength to roast alone.

Why this matters: Roast degree affects flavor, while brewing dose and recipe affect the concentration in your cup.

Read the roasting guideSource: National Coffee Association — Coffee Roasts

How should I store whole-bean coffee?

Keep beans in an airtight, opaque container in a cool, dry, dark place, away from moisture and heat. Grind just before brewing when practical. Freshness depends on the roast, packaging and how the coffee has been stored; a single universal peak-freshness date is not reliable for every bag.

Why this matters: Air, light, warmth and moisture all speed flavor loss or create storage problems.

Can one tasting score prove which coffee is best?

No. A score reflects a particular evaluation method, sample and taster or panel. The Specialty Coffee Association distinguishes sensory descriptions, judgments of quality, physical characteristics and information such as origin traceability. We publish our own scores only for coffees actually brewed and reviewed by us.

Why this matters: A competition result, a roaster's flavor description and an independent tasting score answer different questions; they should not be converted into one universal ranking.

Research update · Genetics

Is Pink Bourbon actually a Bourbon?

Genetic tests reported by Cafe Imports in 2017 and 2023 indicate that sampled Pink Bourbon material belongs closer to Ethiopian landrace ancestry than the traditional Bourbon variety. The older Red × Yellow Bourbon origin story should not be repeated as established fact.

A farmer or roaster may use Pink Bourbon as the trade name for a pink-cherry coffee; a name and cherry color do not prove genetic parentage. Some tested samples had mixed markers, so the identity of any particular lot still needs evidence.

How do I descale my coffee machine?

To descale your coffee machine, use a dedicated descaling solution or a mixture of water and citric acid to dissolve mineral deposits. Run the solution through the machine's brewing cycle, let it sit for 15–30 minutes to break down the limescale, and then flush the system with several cycles of fresh, clean water to remove any remaining residue.

Are automatic coffee machines worth it?

Automatic coffee makers, particularly super-automatic models, are worth it if you prioritize convenience and consistent, one-touch brewing over manual control. While they offer significant time savings and ease of use, they often come with a higher price tag and less flexibility regarding coffee quality compared to semi-automatic machines, which allow for precise adjustments to grind, dose, and extraction.

How long do coffee makers last?

A standard drip coffee machine typically lasts 3 to 5 years, while high-end espresso machines can last 5 to 10 years or more with proper care. The coffee machine lifespan is heavily influenced by appliance maintenance, specifically regular descaling to prevent mineral buildup. Investing in durable coffee equipment and using filtered water are the best ways to extend your brewing gear's longevity.

Why is my French press coffee gritty?

French press coffee is often gritty because the metal mesh filter allows fine coffee particles, known as sediment, to pass into your cup. This is a natural characteristic of immersion brewing. To reduce grit, ensure you are using a coarse, uniform grind size and consider letting the coffee rest for a few minutes after plunging to allow the fines to settle.

What is the difference between a V60 and a Chemex?

The primary difference between a V60 and a Chemex is the filter thickness and the resulting cup profile. The V60 uses a thinner paper filter and has spiral ridges, promoting faster flow and a brighter, more nuanced cup. The Chemex uses a much thicker paper filter, which removes more oils and sediment, resulting in a cleaner, lighter-bodied cup.

Do I need a scale to make good coffee?

Yes, a coffee scale is essential for achieving the brewing precision necessary to make consistently good coffee. Without a scale, you are relying on guesswork, as the density and volume of coffee grounds vary significantly based on the roast and grind. Using a scale ensures you follow an exact coffee recipe, resulting in repeatable, high-quality flavor every time you brew.

What is a portafilter and how does it work?

A portafilter is the handle-mounted, basket-filled tool used in an espresso machine to hold the coffee grounds during extraction. It works by locking into the group head, allowing high-pressure hot water to pass through the compressed coffee bed, creating the concentrated shot known as espresso. It is central to the brewing mechanics and overall espresso extraction quality.

How do I clean my espresso machine?

Effective espresso machine maintenance requires a consistent schedule of daily, weekly, and monthly tasks. Daily, wipe the steam wand and rinse the portafilter. Weekly, perform backflushing with a blind filter to remove coffee oils from the group head. Finally, use a descaling solution every 1–3 months to remove mineral buildup and ensure your coffee equipment remains in peak condition.

What is the difference between a Moka pot and an espresso machine?

The primary difference between a Moka pot and an espresso machine is pressure. A Moka pot uses steam pressure of 1–2 bar to brew strong, concentrated coffee on a stovetop. In contrast, an espresso machine uses an electric pump to generate 9 bar of pressure, which is required to emulsify oils and create the signature syrupy texture and crema of true espresso.

Why is my espresso puck soggy?

A soggy espresso puck is often caused by under-dosing your portafilter, which leaves too much headspace for water to pool. While it can be messy, a wet puck does not necessarily mean your coffee is bad. If your espresso tastes balanced, the puck's appearance is secondary; however, if the shot is sour or watery, try increasing your dose or adjusting your grind size.

What is the difference between a burr and blade grinder?

The primary difference is grind consistency: a burr grinder uses two abrasive surfaces to crush beans into uniform particles, while a blade grinder uses a spinning metal blade to chop them unevenly. Burr grinders are essential for specialty coffee because uniform particle size ensures even extraction, whereas blade grinders produce 'fines' and 'boulders' that lead to inconsistent, muddy flavors.

Are stainless steel coffee filters better than paper?

Stainless steel coffee filters are not necessarily 'better' than paper; they simply offer a different brewing experience. While paper filters produce a clean, sediment-free cup by trapping oils and fines, stainless steel filters allow these oils to pass through, resulting in a fuller, heavier body and more texture in your coffee.
