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.

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.

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 much caffeine is in an espresso shot?

A standard 1-ounce shot of espresso typically contains about 63 milligrams of caffeine. While this is the widely accepted average, the actual caffeine content can range from 40 to 75 milligrams depending on the specific coffee bean variety, the roast profile, and the precise brewing science applied during extraction.

How long does caffeine last in your system?

Caffeine typically has a half-life of three to five hours in the average healthy adult, meaning it takes that long for your body to eliminate half of the consumed amount. While the initial effects peak within 30 to 60 minutes, the stimulant remains in your system for several hours, which can impact sleep quality if consumed late in the day.

Can you be allergic to caffeine?

While a true allergy to caffeine is extremely rare, many people experience adverse reactions that mimic allergic symptoms. These side effects, such as hives, swelling, or difficulty breathing, are often confused with caffeine sensitivity or reactions to other compounds in coffee. If you experience severe symptoms after consuming coffee, it is essential to consult a medical professional for proper testing.

What is the caffeine limit per day?

For most healthy adults, the recommended caffeine limit is up to 400 milligrams per day, which is roughly equivalent to four cups of brewed coffee. While individual sensitivity varies based on genetics and tolerance, exceeding this dosage can lead to jitters, insomnia, or increased heart rate. Always listen to your body and consult a healthcare professional regarding your specific health needs.

What is the "caffeine crash"?

The "caffeine crash" is the physiological dip in energy and alertness that occurs as the effects of caffeine wear off. Caffeine works by blocking adenosine receptors in the brain, which normally signal tiredness. Once the caffeine is metabolized and cleared from your system, the accumulated adenosine floods those receptors, leading to a sudden feeling of fatigue and lethargy.

How many espressos is too many in one day?

For most healthy adults, the FDA suggests a limit of 400 milligrams of caffeine per day, which is roughly equivalent to four to five single shots of espresso. However, individual tolerance varies significantly based on genetics, body weight, and overall health, so it is important to monitor your own physical response to caffeine intake.

Does roast level impact caffeine content by volume vs weight?

Roast level has a negligible impact on caffeine content by weight, as caffeine is highly stable during the roasting process. However, because dark roast beans are less dense and expand more than light roasts, you will get more caffeine by volume if you measure by the scoop, but roughly the same amount if you measure by weight.

Why does coffee make me jittery?

Coffee makes you jittery primarily due to caffeine sensitivity and the rapid absorption of caffeine into your bloodstream. Caffeine is a central nervous system stimulant that blocks adenosine receptors, which can trigger a 'fight or flight' response in sensitive individuals. Factors like high caffeine intake, drinking on an empty stomach, or individual metabolic rates can intensify these side effects.

What is the difference between Arabica and Robusta caffeine?

Robusta coffee (Coffea canephora) contains nearly double the caffeine of Arabica (Coffea arabica). On average, Arabica beans contain 0.8–1.5% caffeine, while Robusta beans range from 1.7–3.5%. This biological difference is a primary factor in their distinct flavor profiles, as caffeine contributes significantly to the bitterness and chemical defense mechanisms of the coffee plant.

How many milligrams of caffeine are in a single coffee bean?

A single coffee bean typically contains between 2 and 6 milligrams of caffeine, depending on the species and size. Arabica beans generally contain less caffeine, averaging around 2 to 3 milligrams per bean, while Robusta beans are more potent, often containing 5 to 6 milligrams or more. Coffee chemistry dictates that these levels vary based on the specific cultivar and growing conditions.

What is the difference between coffee and tea caffeine?

While coffee and tea both contain caffeine, they differ in concentration and how they are absorbed. Coffee typically delivers a higher, faster spike of caffeine, while tea contains L-theanine, an amino acid that promotes relaxation and can smooth out the caffeine's effects, leading to a more sustained, focused energy rather than the jittery rush often associated with coffee.

What is the difference between Arabica and Robusta caffeine levels?

Robusta coffee species contains nearly double the caffeine content of Arabica. While Arabica beans typically range from 1.2% to 1.5% caffeine by dry weight, Robusta beans contain between 2.2% and 2.7%. This significant difference in coffee biology is a primary reason why Robusta is often used in commercial blends to provide a stronger, more potent caffeine kick.

How does roasting affect caffeine concentration?

Roasting has a negligible effect on the actual caffeine content of a coffee bean, as caffeine is a highly stable molecule. However, roast level significantly impacts caffeine per cup based on how you measure. Because light roast beans are denser, a scoop by volume contains more coffee mass—and thus more caffeine—than a scoop of lighter, expanded dark roast beans.

Does dark roast have less caffeine?

Dark roast coffee does not have significantly less caffeine than light roast. While the roasting process slightly reduces caffeine density by weight, the difference is negligible in a standard cup. Because dark roast beans are less dense, you might actually consume more caffeine if you measure your coffee by volume rather than by weight.
