Chocolate Making Training

Lesson 1 • From Pod to Raw Bean

Covers harvesting methods and initial post-harvest handling at the farm level. Proper pod selection and pulp management directly affect fermentation success.

Lesson 2 • Sensory Vocabulary for Chocolate

Introduces standardized tasting language and aroma wheel terminology. Developing sensory vocabulary enables objective quality evaluation used in every subsequent chapter.

Lesson 3 • Chocolate Product Categories

Defines dark, milk, white, and ruby chocolate by composition and regulation. Knowing category standards guides formulation decisions in later chapters.

Lesson 4 • History and Origins of Cacao

Traces cacao from ancient Mesoamerican use to modern global industry. Establishes cultural and commercial context that informs quality standards throughout the course.

Lesson 1 • Microbiology of Fermentation

Explains yeast, lactic acid bacteria, and acetic acid bacteria roles in cacao fermentation. This microbial sequence creates flavour precursors essential to all downstream processing.

Lesson 2 • Evaluating and Grading Dried Beans

Applies international grading criteria to assess mould, insect damage, and flat beans. Consistent grading ensures only suitable beans advance to roasting.

Lesson 3 • Fermentation Box Design and Management

Covers wooden box construction, bean mass ratios, and turning schedules. Proper box management ensures uniform microbial activity across the entire bean batch.

Lesson 4 • Fermentation Duration and Endpoints

Teaches how to identify optimal fermentation completion using cut tests and pH readings. Recognising endpoints prevents under- or over-fermentation defects.

Lesson 1 • Roasting Chemistry and Flavour Development

Explains Maillard reactions, caramelization, and pyrazine formation during roasting. Understanding these reactions allows intentional flavour manipulation in subsequent profile design.

Lesson 2 • Roast Quality Assessment

Uses colour measurement, moisture loss, and sensory evaluation to verify roast accuracy. Systematic assessment creates a feedback loop for continuous profile refinement.

Lesson 3 • Designing and Executing Roast Profiles

Guides students through building time-temperature curves for different bean origins and sizes. Profile execution skills are applied directly in grinding and conching chapters.

Lesson 4 • Roaster Types and Equipment

Compares drum, fluid-bed, and convection roasters by heat transfer mechanism and batch size. Equipment selection determines profile flexibility and production scalability.

Lesson 1 • Measuring and Achieving Target Fineness

Uses micrometer and grindometer tools to verify particle size at each refining stage. Accurate measurement ensures consistent texture across production batches.

Lesson 2 • Ingredient Addition During Refining

Explains when and how to add sugar, milk powder, and cocoa butter during refining. Correct addition timing prevents viscosity spikes and ensures even ingredient distribution.

Lesson 3 • Pre-Grinding and Liquor Production

Covers impact pre-grinders and stone melangers for initial nib breakdown into liquor. Efficient pre-grinding reduces load on fine refiners and shortens total processing time.

Lesson 4 • Ball Mill and Roll Refiner Operation

Teaches operation of ball mills and five-roll refiners for fine particle reduction. Mastery of these machines is central to producing couverture-grade chocolate.

Lesson 1 • Emulsifier Use in Conching

Covers lecithin and PGPR functions in reducing viscosity and yield value during conching. Correct emulsifier dosing minimises cocoa butter use without compromising flow properties.

Lesson 2 • Conching Science and History

Explains volatile evaporation, oxidation, and particle coating mechanisms during conching. Historical context shows how conching transformed chocolate texture and flavour standards.

Lesson 3 • Sensory Evaluation of Conched Chocolate

Applies structured tasting to assess acidity reduction, aroma complexity, and mouthfeel after conching. Sensory data drives decisions to extend or terminate the conche cycle.

Lesson 4 • Conching Phase Management

Guides students through dry, pasty, and liquid conching phases with temperature targets. Phase transitions determine when to add cocoa butter and emulsifiers for optimal results.

Lesson 1 • Continuous Tempering Machine Operation

Covers setup, zone temperature programming, and throughput control on continuous tempering machines. Machine tempering enables consistent large-scale production with repeatable results.

Lesson 2 • Temper Testing and Verification

Uses temper meters, snap tests, and gloss checks to confirm correct crystallisation before moulding. Verification prevents bloom and structural defects in finished products.

Lesson 3 • Cocoa Butter Crystal Polymorphism

Explains the six cocoa butter crystal forms and why Form V is the target for quality chocolate. Crystal science underpins every tempering decision made in subsequent sections.

Lesson 4 • Diagnosing and Correcting Bloom

Identifies fat bloom and sugar bloom by appearance, cause, and corrective action. Bloom diagnosis skills protect product quality and reduce waste in production.

Lesson 1 • Hand-Finishing and Decoration

Develops skills in hand-dipping, transfer sheet application, and cocoa butter spray decoration. Finishing techniques elevate product presentation and differentiate artisan offerings.

Lesson 2 • Cooling Tunnel Management

Explains cooling tunnel zone temperatures and belt speed for proper crystallisation after moulding. Incorrect cooling causes bloom, soft bases, or cracked shells in finished pieces.

Lesson 3 • Depositing and Shell Moulding

Teaches manual and automated chocolate deposition and shell formation for filled confections. Shell thickness control determines structural integrity and ganache-to-chocolate ratio.

Lesson 4 • Enrobing Line Operation

Covers enrober belt speed, curtain thickness, and bottom coating control for uniform coverage. Consistent enrobing protects fillings and delivers a professional appearance.

Lesson 1 • Caramels, Jellies, and Specialty Centres

Teaches wet and dry caramel cooking, pectin-based jellies, and alcohol-based centre techniques. Diverse centre types expand the confection portfolio and require distinct process controls.

Lesson 2 • Water Activity and Shelf Life

Covers water activity measurement and its role in microbial safety and texture over time. Controlling water activity is mandatory for producing commercially safe filled chocolates.

Lesson 3 • Classic and Flavoured Ganache Formulation

Guides students through ratio calculation, infusion techniques, and flavour pairing for ganaches. Mastery of formulation enables creative development of signature confection lines.

Lesson 4 • Pralines, Gianduja, and Nut Pastes

Covers caramelised nut grinding, fat bloom prevention, and gianduja formulation standards. Nut-based fillings require specific fat management to maintain texture and prevent separation.
