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 guide Source: 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 methods Source: 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.

Why is Arabica grown at higher altitudes than Robusta?

Arabica is grown at higher altitudes primarily because it requires cooler temperatures (18–22°C) to thrive, which slows the maturation of the coffee cherry. This extended ripening period allows for the complex accumulation of sugars and acids that define specialty coffee. In contrast, Robusta is a lowland species native to warmer, humid environments; it is genetically adapted to higher temperatures (22–30°C) and lower elevations, where it maintains high yields and disease resistance that would be impossible for the more sensitive Arabica plant.

What is the difference between high-grown and low-grown coffee beans?

High-grown coffee beans are typically denser and more complex due to slower maturation in cooler temperatures, often resulting in higher acidity and sweetness. Low-grown beans mature faster in warmer climates, generally producing a milder, less acidic cup with more body and sometimes increased bitterness. These differences are fundamental to the flavor profile and market value of the coffee.

Why do some regions produce more floral coffee than others?

Floral notes in coffee are primarily driven by a combination of high altitude, specific coffee varieties, and precise processing methods. High elevations slow cherry maturation, allowing for the development of delicate aromatic compounds, while varieties like Gesha are genetically predisposed to floral profiles. Additionally, careful processing preserves these volatile compounds, resulting in the distinct, perfumed qualities found in certain origins.

What is terroir?

Terroir is the collective influence of a specific location’s environment—including soil composition, topography, altitude, and microclimate—on the sensory profile of coffee. It acts as the foundational "flavor blueprint" for a coffee cherry, dictating the potential acidity, sweetness, and body before human intervention. While processing and roasting can highlight or obscure these traits, true terroir represents the immutable, place-specific characteristics that cannot be replicated by planting the same variety in a different ecosystem.
