Read D2 like a business case.
D2 is a one-hour paper and a tenth of the Diploma. It is passed on its own, so a strong D3 cannot rescue it. It asks for principles and the trends behind the figures, not for statistics. After fifteen years in investment banking, I read it as what it is: a business case about wine.
D2 can look like the easy unit: short, no tasting, no regions to learn. It is short. It is also graded on its own and it rewards a way of thinking that wine study rarely asks for: following the money from the vineyard to the glass. In banking, the first question about any business is where the margin is made. D2 asks the same question about a bottle of wine.
This is an independent guide, based on the current specification. Formats change, so check the WSET website before you plan. For the six units together, start with our guide to the Diploma.
What D2 covers
The specification sets three learning outcomes:
- Price. The factors that contribute to the price of a bottle of wine.
- Businesses and routes to market. The types of business that make wine and the options for getting it to the point of sale.
- Marketing. The key considerations in marketing wine.
The exam is one open-response paper of 60 minutes, held on four set dates a year: October, January, March and June. D2 is studied at the start of a Diploma programme, alongside D1. It is graded like every unit: a pass from 55%, a merit from 65% and a distinction from 75%.
Principles and trends, not statistics
WSET's own study guide for D2 is clear on this. You will not be expected to quote statistics in the exam, but you should be able to discuss the trends that they show. It goes further: showing that you understand the principles, through clear and logical arguments, matters more than remembering the exact figures in its tables.
That changes how you revise. Learn mechanisms, not numbers. Why does a large harvest across a region push grape prices down? Why can a stronger currency hurt an exporter's sales abroad? A candidate who can explain the mechanism can answer a question about any country or any vintage.
The price of a bottle, layer by layer
Think of the price as a stack. At the bottom sit the costs of growing the grapes and making the wine. Above them come packaging, transport and the costs of importing: duties and taxes. Then come the costs of selling and marketing, with a margin for each business the bottle passes through on its way to you.
- Costs build in sequence. A duty charged on arrival becomes part of the cost on which the importer's margin is calculated; the next margin is calculated on that. A small change early can mean a large change on the shelf.
- Demand and supply set the frame. Shortage lets producers raise prices; oversupply forces them down. Fashion, the economy and a run of large or small vintages all move the balance.
- Outside forces shift the costs. Legislation, taxes and exchange rates can change the price of a bottle without anything changing in the vineyard.
Follow the money: every cost and every margin ends up in the price on the shelf.
Two of our Journal articles follow the same logic with real decisions: what the price of fine wine really buys and the real landed cost of buying in Europe to drink in Asia.
Who makes the wine and how it reaches you
The study guide covers a wide cast: estates, growers, grower-producers, merchants, grower-merchants, co-operatives, custom crush facilities, virtual winemakers and conglomerates. It then sets out the routes to market, from selling directly to retailers to appointing a distributor, forming a joint venture or using a broker. Then come the places where wine is sold: supermarkets, discounters, specialists, online, travel retail, bars and restaurants. Some markets have rules of their own, such as state monopolies and the three-tier system of the United States.
The guide also follows two contrasting wines through every stage: a high-volume, inexpensive branded Chardonnay and a low-volume, super-premium Cabernet Sauvignon. Use them as your test. For any business model, route or marketing choice, ask which of the two it suits and why. Many good D2 answers come down to explaining why the right choice for one wine is the wrong choice for the other.
Marketing without the jargon
D2 gives you the standard tools: a SWOT analysis of strengths, weaknesses, opportunities and threats; segmentation and market research to find the target market; objectives; then the marketing mix of product, price, people, place and promotion. Knowing the names earns little. Applying them to the wine in the question earns the marks.
A promotion that builds volume for a supermarket brand can damage a super-premium wine whose value rests on scarcity. Say so and say why.
Answering in 60 minutes
- Read the command verb. Describe, explain, evaluate and discuss ask for different things. An evaluation needs a judgement at the end.
- Use the chain. For each point: the decision, the mechanism and the consequence for price, volume, margin or brand.
- Stay in the context. If the question names a type of business or a market, every point must fit it.
- Write by hand, to time. Sixty minutes goes quickly. Plan briefly, then write in plain sentences.
A plan for D2
Study D2 alongside D1, as the specification intends. Write one timed answer by hand every week or two and mark it strictly. Keep a single page of chains (cost to price, decision to consequence) and add to it as you read. Follow the trade press for current trends, since the exam asks you to discuss them. The study guide ends with a reading list to start from.
