Drinks
Tea, coffee, juice and the craft of brewing
Two of the most widely consumed drinks in the world are infusions of leaves and roasted seeds, and both reshaped economies and colonial history.
The unit covers tea and coffee and their processing, juices and soft drinks, brewing and fermented drinks, and water supply - the one that matters most and gets the least attention.
This unit breaks down into 18 short steps and 110 questions, starting at difficulty 3 and building to 4. Below you can see exactly what it covers, how the path is structured, and worked examples with explanations.

What this unit covers
- Tea
- Coffee
- Juice and Soft Drinks
- Brewing and Fermented Drinks
- Water and Supply
Where this fits
Self-contained. The trade history connects to Herbs and Spices.
Where people slip
Green, black and oolong tea come from the same plant. The difference is oxidation after picking, not a different species.
How the unit is structured
Drinks runs as 18 short steps that unlock in order. 13 are practice rounds and 5 are challenge rounds that pull together everything before them. Questions start at difficulty 3 and climb to 4 as you progress.

Where these questions come from. Each unit starts as a plan of the concepts it should cover and the difficulty it should span. Questions are written against that plan with AI assistance, then checked by a validator that rejects anything without a single defensible answer, an explanation, or plausible wrong options. How we write questions sets out the whole process, and corrections are fixed in the bank and reach the site and the app the same day.
