IICCT Chocolate Taster study guide
IICCT Chocolate Taster · Work through your exam, one topic at a time.
The IICCT Chocolate Taster credential is a professional tasting qualification offered by the International Institute of Chocolate and Cacao Tasting. It is aimed at people who need to evaluate chocolate seriously and describe what they taste in a shared, defensible vocabulary: chocolate makers and their production staff, quality and sensory technicians, pastry and chocolate professionals, cacao traders and buyers, and dedicated enthusiasts moving from hobby tasting to structured assessment. The IICCT Chocolate Taster study guide has 10 sections and about 3,912 words.
01Cacao botany, varieties and origins
This domain tests whether you can separate botanical fact from trade marketing: what Theobroma cacao actually is, how the Criollo/Forastero/Trinitario shorthand relates to modern genomic groupings, and why origin, genotype and flavour are three separate claims. Cacao is Theobroma cacao (Malvaceae, formerly Sterculiaceae), diploid with 2n = 20.
374 words, about 2 min02Cacao growing, harvest and post-harvest processing
This domain tests the causal chain from farm to dried bean: how agronomy and post-harvest handling decide whether the chocolate can ever be good, and how to diagnose fermentation and drying faults. Cacao needs 20-30 degrees C, 1,500-2,500 mm of rainfall spread through the year, and shade of roughly 30-50%, especially when young.
393 words, about 2 min03Bean-to-bar manufacturing: roasting, winnowing, refining, conching and tempering
This domain tests the process logic of bean-to-bar: what each unit operation does to flavour, texture and stability, and what happens when it is pushed too far. Roasting, typically 110-160 degrees C for 15-45 minutes, drives off water and acetic acid, develops Maillard and Strecker chemistry (pyrazines, aldehydes, thiols) and sets the balance between fruity and roasted notes.
406 words, about 2 min04Chocolate ingredients, formulations and labelling
This domain tests the ingredient logic and the regulation behind a label: what the percentage means, what may legally be called chocolate, and how formulation changes texture and flavour. Cocoa mass brings solids, butter and flavour.
403 words, about 2 min05Sensory evaluation methodology and tasting technique
This domain tests whether you can assess chocolate the way a trained panel does - controlled, reproducible, descriptive rather than personal - and whether you understand the methods behind sensory claims. Analytical tests measure differences or attribute intensities; hedonic tests measure liking.
390 words, about 2 min06Flavour attributes, aroma lexicon and defect recognition
This domain tests your flavour vocabulary and diagnostic accuracy: naming what you perceive, at what intensity, and tracing it to a cause rather than a guess. Use a structured wheel: fruity (citrus, red berry, tropical, dried fruit), floral, nutty, caramel, honey, spicy, woody, earthy, smoky, savoury, dairy.
383 words, about 2 min07Chocolate styles, origins and product categories
This domain tests product literacy: the categories chocolate is sold in, how they are made and named, and what claims such as couverture, single estate, bean-to-bar and ruby actually promise. Dark chocolate is cocoa mass, cocoa butter and sugar, commonly 55-85%; higher percentages mean less sugar and more cocoa solids, but not automatically more aroma.
414 words, about 2 min08Storage, shelf life and quality defects
This domain tests whether you can keep chocolate in condition, recognise a fault when it appears, and distinguish storage defects from manufacturing ones. Store at 15-18 degrees C with relative humidity below 50%, away from light, odours and vibration, in airtight wrapping.
373 words, about 2 min09Sustainability, ethics and supply chain
This domain tests how chocolate gets from farm to bar ethically and traceably, and whether you can discuss certification, price and deforestation claims with evidence rather than slogans. Cocoa is grown mostly by smallholders, and farm-gate prices have historically left many below a living income.
409 words, about 2 min10Professional tasting practice, vocabulary and communication of results
This domain tests professional communication: tasting with a repeatable method, using agreed vocabulary, scoring transparently and writing results that others can act on. Standardise what you can: blind coding, 20-22 degrees C samples, 3-5 g pieces, water and neutral cleansers, rest between samples, no strong flavours beforehand.
