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.

Understand coffee geneticsSource: World Coffee Research — Arabica catalog

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.

Explore brewing methodsSource: National Coffee Association — Storage and Shelf Life

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.

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.

What is the best kettle for pour-over coffee?

The best kettle for pour-over coffee is an electric gooseneck kettle with precise temperature control, such as the Fellow Stagg EKG or Bonavita Variable Temperature model. These tools are essential pieces of coffee equipment because their narrow spouts restrict water flow to 17–40 ml/sec, allowing you to saturate the coffee bed evenly and prevent channeling during the brewing process.

How do I choose the right coffee filter for my brewer?

Choosing the right coffee filter depends on your desired flavor profile: paper filters produce a clean, bright cup by absorbing oils and trapping fines, while metal filters allow oils and some sediment to pass through for a fuller, richer body. Always ensure the filter shape and size are compatible with your specific brewing equipment to ensure proper extraction.

What is the difference between conical and flat burrs?

The primary difference between conical and flat burrs lies in their geometry and the resulting grind profile. Conical burrs use two cone-shaped pieces to crush beans, often producing a wider range of particle sizes that can add body and complexity. Flat burrs use two parallel rings to cut beans, typically resulting in a more uniform grind that enhances clarity and flavor separation.

Why is my Moka pot sputtering?

A Moka pot sputters at the end of the brew because the water in the bottom chamber has been exhausted, allowing steam to force its way through the coffee grounds. This transition from liquid water to steam causes the characteristic gurgling sound. If your pot sputters prematurely or violently, it is likely due to excessive heat, a compromised gasket seal, or a grind size that is too coarse, which allows pressure to escape too rapidly.

A bottomless portafilter is a diagnostic tool used to visualize the underside of an espresso basket during extraction. By removing the spouts, it exposes the coffee puck, allowing baristas to identify uneven flow, channeling, and improper tamping in real-time. It serves as a critical feedback mechanism for refining grind size, distribution, and puck preparation, ensuring that water passes through the coffee bed uniformly rather than finding paths of least resistance.

What is the difference between a conical and flat burr grinder?

The primary difference lies in particle distribution: flat burrs use two parallel discs to produce a more uniform, unimodal grind that enhances flavor clarity, while conical burrs use a cone-within-a-ring geometry to create a bimodal distribution, which adds body and texture. Flat burrs rely on centrifugal force to push grounds outward, whereas conical burrs utilize gravity to pull beans vertically through the cutting path. Choosing between them depends on whether you prioritize distinct flavor separation or a traditional, syrupy mouthfeel.

What is the best water temperature for drip coffee?

The best water temperature for drip coffee is between 195°F and 205°F (90.5°C to 96°C). This range is the industry standard for effective coffee extraction, ensuring you dissolve desirable sugars and acids without over-extracting bitter compounds. If your coffee equipment runs cooler than this, you may experience weak or sour results, while excessively hot water can lead to harsh, burnt flavors.

What is a gooseneck kettle?

A gooseneck kettle is a specialized vessel featuring a long, slender, curved spout designed to provide precise control over the flow rate and placement of water during manual brewing. By restricting the water stream, it allows the brewer to saturate coffee grounds evenly, preventing the channeling and agitation that occur with standard kettles. This mechanical precision is essential for consistent extraction, ensuring that the delicate flavor compounds developed by the producer are balanced rather than washed away by an uneven deluge.

What is a French press?

A French press is a full-immersion brewing device that extracts coffee by steeping coarse grounds in hot water before using a metal mesh plunger to separate the solids from the liquid. By allowing the coffee oils and fine particles to remain in the final brew, this method produces a cup characterized by a heavy, viscous body and pronounced texture, distinguishing it from the clarity achieved by paper-filtered methods.

Is a manual grinder better than an electric one?

A manual grinder is often better for value and grind quality at lower price points, while an electric grinder is superior for speed, convenience, and high-volume brewing. Manual grinders avoid motor-induced heat and vibration, offering professional-grade consistency for a fraction of the cost of electric equivalents, provided you are willing to put in the physical effort.
