The General Certificate in Brewing (GCB) is awarded by the Chartered Institute of Brewers and Distillers (CIBD), formerly the Institute of Brewing and Distilling. It covers the whole brewing process plus quality, hygiene, engineering and health and safety. This guide sets out the 2027 exam dates and fees, maps the version 6.0 syllabus, explains the remotely invigilated exam format, and works through the calculation skills the syllabus flags.
What the qualification covers
The GCB covers the entire brewing process and the supporting brewery functions, and is aimed at brewers who have not previously studied brewing science formally.
The qualification covers the whole brewing process: raw materials, wort production, fermentation, maturation and beer finishing. Around that core, it also introduces quality and sustainability, plus brewery functions such as hygiene, engineering, utilities, and health and safety. CIBD describes it as a globally recognised technical qualification.
CIBD positions the GCB for brewers who have never formally studied brewing science and technology. It also states the certificate provides the knowledge expected of a senior operator or team leader in a larger brewery, or of brewers in small and medium-sized breweries.
Issuer and syllabus version
The awarding body now operates as the Chartered Institute of Brewers and Distillers; the applicable exam scope is syllabus version 6.0, effective 30 January 2025.
The programme was formerly known under the Institute of Brewing and Distilling name; the current pages and the syllabus are published by the Chartered Institute of Brewers and Distillers (CIBD). If you see older IBD references, they point to the same body under its previous branding.
CIBD is explicit that the scope of its examinations is always the syllabus and is not limited to the learning materials. The version 6.0 syllabus, effective 30 January 2025, tells candidates to have full knowledge of every topic, because questions can be drawn from any of them. Download the syllabus PDF from the GCB page and use it as your checklist, not the topic list on any study site.
The syllabus introduction also warns that the examination may include some calculation questions. That single sentence should shape how you revise: descriptive recall alone is not enough.

How the exam is delivered
You sit the exam online under remote invigilation, after downloading the exam platform application; questions can come from any syllabus topic and may include calculations.
CIBD emails preparation instructions that include downloading its exam platform application. Use the computer on which you installed it. On exam day, connect to the remote invigilator and complete the required checks before starting.
Because the scope is the whole syllabus, no unit is safely skippable. The syllabus also flags calculation questions, so build arithmetic practice into your plan rather than hoping to recognise a formula on the day. The retrieved pages do not state the number of questions or the exam duration; confirm those details with CIBD when you register.

The syllabus at a glance
The version 6.0 syllabus has eight units, running from an introduction to brewing through raw materials, wort production, fermentation, maturation, quality, hygiene, and engineering and the environment.
The table below condenses each unit to its main focus so you can plan study blocks. The official document goes much deeper, listing the specific topics candidates must be able to explain or demonstrate familiarity with. Read the full syllabus alongside this table, because exam questions can be drawn from any listed topic.
| Syllabus unit | What it covers |
|---|---|
| 1. Course introduction | Definition of beer, beer styles, and an overview of production from raw materials to packaging |
| 2. Raw materials | Barley and malt, adjuncts, water sources and treatment, hops and hop products, brewing yeast |
| 3. Wort production | Milling, mashing, wort separation, wort boiling, and clarification, cooling and oxygenation |
| 4. Fermentation | Fermentation theory and vessels, pitching, flavour compounds, yeast management and propagation |
| 5. Maturation | Warm and cold maturation, conditioning, cooling, carbonation, blending and filtration |
| 6. Quality | Process control, quality management systems including HACCP, sensory assessment, dissolved oxygen |
| 7. Hygiene | Microbiological contamination and control, plant cleaning and CIP systems |
| 8. Engineering and the environment | Maintenance, sustainability and utilities, effluent, co-products, health and safety |
A worked calculation: pitching rate
The syllabus lists calculating the yeast pitching rate for fermentation as an examinable topic, so it is worth rehearsing the arithmetic end to end with clear units.
This original arithmetic example supplies its own assumptions. A batch contains 5,000 litres of wort, or 5,000,000 millilitres. Assume a target of 10 million viable cells per millilitre of wort and a slurry concentration of 2.0 billion viable cells per millilitre. These figures are exercise premises, not a recommended brewery pitching rate.
Step one: total cells needed equals wort volume in millilitres times target rate, so 5,000,000 × 10,000,000 = 5.0 × 10¹³ cells. Step two: slurry volume needed equals total cells divided by slurry concentration, so 5.0 × 10¹³ ÷ 2.0 × 10⁹ = 25,000 millilitres, or 25 litres.
Check the units at each step: wort volume times viable cells per unit of wort gives the total viable cells needed; dividing by viable cells per unit of slurry gives a slurry volume. Convert the final millilitres to litres.
Practice task with answer
Work the following multi-step calculation, then check your answer and reasoning below.
This task follows the same structure as the worked example but adds one step: slurry viability. Work it on paper before reading the answer.
Practice task
A brewery is pitching 2,500 litres of wort (2,500,000 mL). Using the same stated exercise premise of a target rate of 10 million viable cells per millilitre of wort, the lab counts the slurry at 2.5 billion cells per millilitre, but the viability test shows only 80% of those cells are viable. Under these exercise assumptions, what slurry volume supplies the target number of viable cells?
Show answer
12,500 mL of slurry, which is 12.5 litres.
First correct the concentration for viability: 2.5 billion × 0.80 = 2.0 billion viable cells per millilitre. Total cells needed: 2,500,000 mL × 10,000,000 cells/mL = 2.5 × 10¹³ cells. Slurry volume: 2.5 × 10¹³ ÷ 2.0 × 10⁹ = 12,500 mL. If you skip the viability correction, the calculation gives 2.5 × 10¹³ ÷ 2.5 × 10⁹ = 10,000 mL and supplies 20% fewer viable cells than the target in this example. The 10-million-cell rate is an assumption for this task; the pitch rate you would actually use comes from your study materials and your brewery's process.
How to prepare
Plan 60 to 80 hours of study across the eight syllabus units, use the end-of-unit multiple-choice checks, and consider the optional Set for Success sessions.
CIBD states a minimum study requirement of 60 to 80 hours. Spread that across the units rather than compressing it into the final weeks, and tick topics off the syllabus PDF rather than the course contents page, because the exam scope is the syllabus itself.
The online, self-directed learning material explains every syllabus topic and includes multiple-choice questions at the end of each unit, which you can use as low-stakes checks. Access terms differ: members keep three years of access to the materials, while non-members get 90 days after their exam. Check your access terms and plan your exam revision before your sitting.
Set for Success is CIBD's optional three-session online preparation course, with live sessions of up to 3.5 hours each over three weeks. Tutors work through multiple-choice questions of a similar standard to the exam, and recordings remain available afterwards. It is recommended by CIBD for all GCB candidates, but it is a support course, not a requirement.

Preparation pitfalls to avoid
The avoidable errors are studying only the learning material, skipping calculations, missing a registration closing date, and re-registering after a purchase-code error.
Use the syllabus as your coverage checklist and the learning materials to study its topics. Include the calculation types the syllabus names; reading explanations alone does not check whether you can work them through.
Two administrative traps are also worth knowing. Registration for each sitting closes weeks in advance, so diary the closing date for your chosen sitting, not just the exam day. And if you register with a purchase code and see an error, do not attempt to register again, because that can create a duplicate registration; CIBD asks you to email corporatebookings@cibd.org.uk instead.
