Wine law and labelling: reading any bottle
Wine law looks like a memory test and is really a comprehension test. Examiners want to know whether you can read an unfamiliar label and say what its words legally guarantee. Almost all of it reduces to one organising contrast and one hierarchy. This guide covers both, then the terms that trip candidates up.
The organising contrast
Old World labels lead with place. A bottle says Chablis, and the grape is not printed because the appellation rules already require it to be Chardonnay. The label assumes you know what the place implies.
New World labels lead with grape and brand. A bottle says Marlborough Sauvignon Blanc, naming the variety explicitly and treating the region as an address rather than a rulebook.
That is a tendency rather than a law, and it is eroding as New World producers emphasise site and Old World producers add varietal labelling for export. But it remains the fastest way to orient yourself in front of an unfamiliar bottle, and it is how the topic is framed at Level 2.
The EU hierarchy
Three tiers, distinguished by how tightly they are drawn and how much they regulate:
- PDO, Protected Designation of Origin. The tightest tier. A smaller defined area, with rules covering permitted grape varieties, maximum yields, minimum alcohol and often winemaking and ageing methods. All the grapes must come from the named area.
- PGI, Protected Geographical Indication. A larger area with looser rules, permitting a wider range of varieties and higher yields. A defined majority of the grapes, commonly 85 percent, must come from the named area, though the exact figure varies.
- Wine without geographical indication. The base tier, which may still state variety and vintage under certain conditions.
The crucial point for an exam answer is that PDO regulates method as well as origin. It tells you not only where the wine came from but, to a significant degree, how it was allowed to be made.
The national terms map onto those tiers directly. At PDO level: AOC or AOP in France, DOC and DOCG in Italy, DO and DOCa in Spain, DOC in Portugal, and both Qualitätswein and Prädikatswein in Germany. At PGI level: IGP in France, IGT in Italy, Vino de la Tierra in Spain and Landwein in Germany.
Germany is worth separating out because it classifies within PDO by ripeness at harvest rather than by geography alone. Prädikatswein sits above Qualitätswein and is subdivided by must weight through Kabinett, Spätlese, Auslese and the sweet categories above them, with chaptalisation permitted for Qualitätswein but not for Prädikatswein. The detail is set out in Germany for WSET.
The New World model
Appellation systems outside the EU generally regulate origin only. The American AVA, the Australian GI and the South African Wine of Origin scheme all define boundaries and require a stated proportion of fruit to come from within them, but they do not tell a producer which varieties to plant or how to make the wine. Minimum percentages for stated variety, vintage and origin are common, frequently around 85 percent, and vary between countries.
This is the difference to state plainly in an answer: EU appellations constrain practice, New World appellations describe geography.
What the label must say, and what it merely may
Mandatory information under EU rules broadly covers country of origin, the quality designation, actual alcoholic strength, nominal volume, the bottler's details, an allergen declaration for sulfites, and a lot number, with sweetness required on sparkling wine. Everything else is optional: vintage, variety, producer name, vineyard, and the various quality-suggesting terms.
That optional category is where candidates lose marks. Reserva and Gran Reserva in Spain carry legally defined minimum ageing periods. Riserva in Italy is legally defined, but separately within each appellation, so it means different things in different DOCs. Reserve in most New World countries has no legal definition at all and is purely a marketing term. Spain's system is set out further in Rioja for WSET.
Classifications are a separate layer again, sitting on top of appellation law rather than inside it. Bordeaux's 1855 ranking classifies châteaux rather than vineyard land, and Burgundy's ranks the vineyards themselves, which is why the two behave so differently. See Bordeaux for WSET for that distinction.
Rules and thresholds in this area are periodically revised, so treat specific figures as indicative and confirm current requirements against your study materials.
FAQ: wine law questions
What is the difference between PDO and PGI? PDO covers a smaller area with stricter rules on varieties, yields and methods, and requires all grapes from the area. PGI covers a larger area with looser rules and a majority-of-grapes requirement.
Which national terms are PDO? AOC or AOP, DOC and DOCG, DO and DOCa, Portugal's DOC, and Germany's Qualitätswein and Prädikatswein.
How do New World appellations differ from EU ones? They generally regulate origin only, defining boundaries and minimum percentages without dictating grape varieties or winemaking methods.
Is Reserve a legally defined term? In Spain, Reserva and Gran Reserva carry legal minimum ageing. In Italy, Riserva is defined separately within each appellation. In most New World countries, Reserve has no legal meaning.
Why is the grape often absent from Old World labels? Because the appellation rules already specify which varieties are permitted, so the place name implies the grape.
