1Which coffee species is the exclusive focus of the CQI Arabica Q Grader certification?

A.Coffea canephora

B.Coffea arabica

C.Coffea liberica

D.Coffea excelsa

Explanation: The Arabica Q Grader program certifies sensory evaluation of Coffea arabica specifically. A separate Q Robusta (R Grader) program exists for Coffea canephora. Arabica accounts for roughly 60% of global production and is prized for higher acidity, aromatic complexity, and lower caffeine (~1.2%) vs robusta (~2.2%).

2Which arabica variety, originating in Ethiopia and famously developed in Boquete, Panama, is known for intense jasmine and bergamot notes?

A.Caturra

B.Mundo Novo

C.Gesha (Geisha)

D.Catuai

Explanation: Gesha (also spelled Geisha) originated in the Gesha forest of Ethiopia and was propagated in Panama's Boquete region by Hacienda La Esmeralda in the early 2000s. It is famed for delicate, floral, tea-like cups with jasmine, bergamot and stone-fruit notes, and has repeatedly set auction price records.

3Caturra is a natural single-gene dwarf mutation of which variety?

A.Typica

B.Bourbon

C.SL28

D.Gesha

Explanation: Caturra was discovered in Minas Gerais, Brazil as a single-gene (Ct) dwarf mutation of Bourbon. The compact plant allows higher density planting and easier harvest. It retains much of Bourbon's cup quality and became foundational in Colombia and Central America.

4Pacamara is a cross between which two varieties?

A.Pacas and Maragogype

B.Caturra and Mundo Novo

C.Typica and Bourbon

D.SL28 and SL34

Explanation: Pacamara was developed in El Salvador by ISIC (1958) by crossing Pacas (a Bourbon mutation) with Maragogype (an elephant-bean Typica mutation). It produces very large beans and often shows herbaceous, chocolate, and tropical fruit notes prized in competitions.

5SL28 and SL34 are cultivars most closely associated with which origin?

A.Guatemala

B.Kenya

C.Brazil

D.Indonesia

Explanation: SL28 and SL34 were selected at Scott Agricultural Laboratories in Kenya in the 1930s–40s. SL28 traces to drought-tolerant Tanganyika material with Bourbon lineage; SL34 to French Mission (Bourbon). They define the classic Kenya cup — blackcurrant, grapefruit, and winey acidity.

6Castillo, Colombia and Catimor varieties share which key agronomic trait?

A.Extreme dwarfism

B.Resistance to coffee leaf rust (Hemileia vastatrix)

C.Very low caffeine

D.Red cherry color only

Explanation: Castillo, Colombia, and Catimor all derive from Hibrido de Timor (a natural arabica × robusta hybrid) crossed with arabica varieties, conferring resistance to coffee leaf rust (Hemileia vastatrix). Historically they were criticized for cup quality, but modern Castillo selections have narrowed the gap.

7Which statement about Coffea canephora (robusta) is correct?

A.It is typically self-pollinating with 22 chromosomes

B.It is cross-pollinating with 22 chromosomes and roughly double the caffeine of arabica

C.It has higher perceived acidity than arabica

D.It originated in Yemen

Explanation: Robusta (C. canephora) is diploid (2n=22), outcrossing (self-incompatible), and contains ~2.2–2.7% caffeine vs arabica's ~1.2%. It tolerates heat and disease but generally shows lower acidity, more body, and grain/rubber/peanut notes. Arabica is tetraploid (2n=44) and self-pollinating.

8Ethiopian 'heirloom' or 'landrace' refers to:

A.A single registered variety with stable genetics

B.A genetically diverse mix of indigenous arabica populations, often unmapped

C.Only JARC-released selections

D.Hybrids with robusta

Explanation: Ethiopian 'heirloom' is shorthand for the enormous genetic diversity of indigenous arabica landraces growing semi-wild and in garden plots. It is not one variety. JARC (Jimma Agricultural Research Center) has released specific named selections (e.g., 74110, 74112, Kurume), but most lot descriptions still simply read 'heirloom.'

9Which Ethiopian region is traditionally associated with dry-processed, wild-fruit and blueberry-like cups?

A.Yirgacheffe

B.Limu

C.Harrar

D.Bebeka

Explanation: Harrar is a long-standing natural-process origin in eastern Ethiopia, often showing blueberry, jammy fruit, and winey notes. Yirgacheffe and Limu are more associated with washed processing and delicate floral/citrus profiles, though naturals are produced in all regions today.

10In Kenya's auction grading system, what does the grade 'AA' primarily indicate?

A.Cup score above 85

B.Bean screen size (~17–18/64 inch)

C.Organic certification

D.Single estate origin

Explanation: Kenya's physical grade classifications (E, AA, AB, PB, C, TT, T) are defined primarily by screen size, not cup quality. AA is screen 17/18; AB is screen 15/16; PB is peaberry. Cup quality is graded separately by the outturn and by licensed cuppers.

SCA Q Grader Study Tips from Top Performers

1Memorize the SCA Cupping Protocol — 8.25 g of coffee per 150 mL water (ratio 1:18.18), grind within 15 minutes of cupping, water temperature 92-96°C (200°F), 4-minute crust break, skim the crust, slurp from each cup at cooling intervals. The 10 attributes scored 0-10 are Fragrance/Aroma, Flavor, Aftertaste, Acidity, Body, Balance, Uniformity, Clean Cup, Sweetness, and Overall — with taint and fault deductions producing a 100-point total (specialty ≥80).

2SCA Green Coffee Defect Handbook — zero tolerance for Category 1 (primary) defects in a 350 g sample: full black, full sour, dried cherry/pod, large stones or foreign matter, severe insect damage. Up to 5 Category 2 (secondary) defects allowed for specialty grade: partial black, partial sour, parchment, floater, immature/unripe, withered, shell, broken/chipped/cut, hull/husk, slight insect damage. Use moisture meters for 10-12% target and water activity meters for aw 0.55-0.65.

3Organic acids and the SCA Taste Training Kit — citric (bright, lemon-lime citrus), malic (green apple, crisp), acetic (vinegar, fermented), quinic (astringent, developed-roast), lactic (yogurt, creamy), phosphoric (cola, round acidity). Practice at low and moderate thresholds, and drill matching-pair and triangle tests using the SCA kit to build sensitivity before the exam.

4Arabica varieties cheat-sheet — Typica (parent, balanced), Bourbon (sweet, complex), Caturra (compact Bourbon mutation), Catuai (Mundo Novo x Caturra), SL28/SL34 (Kenya, intense blackcurrant acidity), Gesha/Geisha (Panama, floral/jasmine, bergamot), Pacamara (Pacas x Maragogype, large bean, floral), F1 hybrids (Starmaya, Centroamericano, Milenio — disease resistant). Arabica is self-pollinating and tetraploid (2n=44); robusta (canephora) is self-sterile and diploid with ~2x caffeine and higher chlorogenic acid.

52023 SCA Coffee Value Assessment (CVA) — four components: Physical (green grading and moisture/density), Descriptive (intensity scales with CATA check-all-that-apply flavor descriptors from the SCA Flavor Wheel), Affective (1-9 Likert impression of quality), Extrinsic (origin, certification, story). CVA supplements or replaces the traditional 100-point cupping form and is increasingly adopted through 2026 — know how the Descriptive CATA interacts with the Flavor Wheel and WCR Lexicon.

Frequently Asked Questions

What is the SCA / CQI Q Grader Certification?

The Q Grader Certification (Arabica) is the leading international credential for coffee quality evaluation. Administered by the Coffee Quality Institute (CQI) in partnership with the Specialty Coffee Association (SCA), the exam consists of 22 sensory and knowledge tests embedded in a 6-day in-person course. Q Graders evaluate Coffea arabica using the SCA Cupping Protocol and score coffees on a 100-point scale against the specialty threshold of 80.

Who is eligible to take the Q Grader exam?

The Q Grader credential is open to coffee industry professionals — green buyers, roasters, quality-control technicians, exporters, baristas, and others working with coffee. There is no formal academic prerequisite, but prior cupping experience and sensory training are strongly recommended. Candidates should complete regular cuppings with a panel and practice with the SCA Taste Training Kit and Le Nez du Café before enrolling.

What is the format of the Q Grader exam?

The exam comprises 22 tests administered across a 6-day in-person course — 4 olfactory triangulations using Le Nez du Café, organic acids identification and matching pairs, sensory skills triangle tests, cupping triangulations across multiple origins, SCA cupping form calibration, green grading against the SCA Green Coffee Defect Handbook (Category 1 and Category 2), sample roast identification, and a multiple-choice General Knowledge exam. Candidates must score at least ~75% on each of the 22 sections.

How much does the 2026 Q Grader course and exam cost?

Most 2026 Q Grader courses are priced at approximately $1,800-$2,500 for the 6-day course and exam package, varying by authorized training provider and region. Candidates should also budget for a Le Nez du Café kit (~$500), SCA Taste Training Kit, and travel or lodging for in-person attendance. Verify the current schedule with the authorized CQI Q Instructor before enrolling.

How long is a Q Grader certification valid?

Q Grader status is valid for 3 years from the date of initial certification. To maintain active status, Q Graders must re-calibrate every 3 years with an authorized Q Instructor. Re-calibration is shorter and less expensive than the full course. Q Graders who allow their status to lapse beyond the calibration window may need to repeat the full 6-day course.

What is the pass rate?

Historically, approximately 75-85% of candidates pass at least one section on the first attempt, and the overall initial-pass rate across all 22 tests in a single sitting is considerably lower because of the breadth of the exam. Most candidates retake one or more individual sections within the allowed 6-month window; the sensory triangulations and organic acids tests are commonly retaken.

What are the highest-yield topics?

Highest-yield topics include the SCA Cupping Protocol (8.25 g / 150 mL at 92-96°C with a 4-minute crust break), the 10 cupping attributes scored 0-10, SCA Green Coffee Defect Handbook Category 1 and Category 2, Le Nez du Café aromas and olfactory triangulation, organic acids (citric, malic, acetic, quinic, lactic, phosphoric), arabica cultivars (Typica, Bourbon, Caturra, SL28, Gesha, Pacamara) and WCR variety catalog, processing methods (washed, natural, honey, anaerobic), the 2016 SCA Flavor Wheel and WCR Sensory Lexicon, the 2023 SCA Coffee Value Assessment, and water chemistry (TDS 150 mg/L).

How should I study for the Q Grader exam?

Use a 3-6 month structured plan before the course. Train daily with the SCA Taste Training Kit at threshold levels, drill the 36-aroma Le Nez du Café kit, run triangulation practice, and host cupping panels weekly with calibration against a reference scorer. Study the SCA Cupping Protocol, Green Coffee Defect Handbook, arabica variety catalog, processing methods, SCA Flavor Wheel, and the 2023 Coffee Value Assessment. Review the General Knowledge MCQ syllabus in the final month and take timed mock exams.
