Section 3 · Still Wines of the World
The Loire Valley
The Loire Valley follows France's longest river for over 1,000 kilometres from the mountains of central France to the Atlantic coast. It is a region of extraordinary diversity, producing everything from bone-dry Sauvignon Blanc to lusciously sweet Chenin Blanc, from light Cabernet Franc reds to world-class sparkling wine, all united by a cool-climate signature of bright acidity and freshness.

Why the Loire Matters
The Loire Valley is one of the most important regions on the WSET Level 3 exam, and for good reason. It showcases the incredible versatility of Chenin Blanc (dry, off-dry, sweet, and sparkling, all from one grape), provides the French benchmark for Sauvignon Blanc (Sancerre and Pouilly-Fumé), and demonstrates how Cabernet Franc performs as a stand-alone variety in a cool climate.
The exam loves the Loire because it tests whether you understand how a single grape can produce radically different styles depending on climate, site, and winemaking decisions. Chenin Blanc is the ultimate example of this versatility.

Geography and Climate
The Loire is France's longest river, running roughly 1,000 kilometres from the Massif Central mountains in the south-east to the Atlantic coast at Nantes. Wine is produced along much of its length, but the four key sub-regions stretch from the coast inland to the eastern hills.
Climate Gradient
One of the most important things to understand about the Loire is that the climate changes significantly from west to east:
- Pays Nantais (west): Maritime climate. Influenced by the Atlantic. Mild temperatures, moderate rainfall, some risk of frost. The ocean moderates extremes.
- Anjou-Saumur and Touraine (middle): Maritime with some continental influence. Slightly warmer summers, cooler winters. The tuffeau limestone caves here are important for sparkling wine production and cellar storage.
- Central Vineyards (east): Continental climate. Further from the ocean's moderating effect. Warmer summers, colder winters, greater temperature extremes. Frost is a significant risk in spring.
Despite these differences, the entire Loire Valley is fundamentally a cool-climate region. This is what gives all Loire wines their hallmark high acidity: whether it's a dry Muscadet, a sweet Vouvray, or a red Chinon.
Pays Nantais
The westernmost wine region of the Loire, surrounding the city of Nantes near the Atlantic coast. This is Muscadet country.
Muscadet
Muscadet is made from Melon de Bourgogne (often just called Melon), a grape grown almost nowhere else in France. On its own, Melon produces lean, neutral wine. What transforms it is the technique of sur lie ageing: leaving the wine on its fine lees (dead yeast cells) through the winter after fermentation.
What sur lie does: The lees release compounds that add body, texture, and a subtle bready or creamy character to the wine. Sur lie Muscadet has more weight and complexity than wine racked off its lees immediately. Bottles labelled "Muscadet Sèvre et Maine sur lie" (the most common and best sub-appellation) must remain on lees until bottling, with a minimum period specified.
Style: Dry, light-bodied, high acidity, with lemon, green apple, and sometimes a slightly saline, mineral character. The classic pairing is with oysters and other shellfish, the wine's acidity and salinity mirror the flavours of the sea.
Muscadet Sub-Appellations
Anjou-Saumur
Moving upstream (east) from Nantes, you reach Anjou-Saumur, the heartland of Chenin Blanc in the Loire and one of the most versatile wine-producing areas in France. From the same grape and the same general area, producers make bone-dry whites, off-dry whites, lusciously sweet dessert wines, still rosé, and traditional-method sparkling wines.
Chenin Blanc: The Star of the Middle Loire
Chenin Blanc in Anjou-Saumur
Chenin Blanc is one of the most versatile grapes in the world, and Anjou-Saumur is where it reaches its highest expression. The grape has naturally very high acidity, which is preserved in the Loire's cool climate. This acidity means it can support significant residual sugar without tasting cloying, which is why it works across the entire spectrum from dry to sweet.
Flavour profile: Green apple, quince, honey, wet wool, chamomile, lanolin. With age, Chenin develops extraordinary complexity: beeswax, marzipan, dried apricot. Botrytis-affected sweet versions add marmalade and candied fruit notes.
Key Anjou-Saumur Appellations
Savennières
A small appellation producing dry Chenin Blanc of exceptional intensity and ageing potential. The wines are full-bodied, bone-dry, and austere in youth, with mineral, quince, and chamomile character. They often need several years to open up and can age for decades. Within Savennières, two single-vineyard appellations, Coulée de Serrant and La Roche aux Moines: are considered Grand Cru quality.
Coteaux du Layon
The most important sweet wine appellation in the Loire. Sweet Chenin Blanc made from grapes affected by noble rot (botrytis cinerea) or simply very ripe grapes left to desiccate on the vine. Rich, honeyed, with apricot, quince, and marmalade flavours balanced by Chenin's trademark acidity.
Within Coteaux du Layon, two sub-appellations produce the finest sweet wines:
- Bonnezeaux: a Grand Cru for sweet Chenin Blanc. Rich, concentrated, and long-lived.
- Quarts de Chaume: another Grand Cru. Even more concentrated and prestigious. Tiny production.
Saumur and Saumur-Champigny
Saumur produces dry white Chenin Blanc (sometimes blended with Chardonnay and Sauvignon Blanc) and is also the base for Saumur Mousseux and Crémant de Loire: traditional-method sparkling wines that represent excellent value compared to Champagne.
Saumur-Champigny is the top red appellation in Anjou-Saumur, producing Cabernet Franc reds. These are light to medium-bodied, with bright red cherry and raspberry fruit, distinctive pencil-shaving and leafy herb notes, and fresh acidity. Best drunk relatively young.
Rosé d'Anjou and Cabernet d'Anjou
Rosé d'Anjou is a medium-sweet rosé made primarily from Grolleau. It's simple and commercial. Cabernet d'Anjou is a step up, a medium-sweet rosé made from Cabernet Franc and/or Cabernet Sauvignon. Both are off-dry to medium-sweet, which is important to note for the exam: Loire rosés are not always dry.
Exam Angle
If the exam asks about Chenin Blanc's versatility, use the Loire as your example. From Savennières (bone-dry, austere, age-worthy) to Vouvray (dry to sweet) to Coteaux du Layon (lusciously sweet) to Crémant de Loire (sparkling), one grape does it all. The key enabling factor is Chenin Blanc's naturally high acidity, which provides structure and balance across every style.
Touraine
Centred on the city of Tours, Touraine is the middle section of the Loire and home to some of the region's most famous wines, particularly for Chenin Blanc (Vouvray) and Cabernet Franc (Chinon, Bourgueil).
Vouvray
Vouvray is perhaps the ultimate expression of Chenin Blanc's versatility. From a single appellation, producers make wines in four distinct styles:
- Sec: dry. Crisp, apple, and mineral.
- Demi-sec: off-dry. Slightly sweet, with honey and pear notes. The residual sugar balances the high acidity beautifully.
- Moelleux: sweet. Made from botrytis-affected or very ripe grapes. Honey, quince, dried apricot.
- Pétillant / Mousseux: sparkling. Traditional-method Chenin Blanc with apple, brioche, and honeyed notes.
The style produced in any given year depends heavily on the vintage: in warm years, grapes ripen fully and sweet wines are made; in cooler years, the focus shifts to dry and sparkling. Tuffeau limestone (the chalky local rock) is the dominant soil and provides the caves where sparkling wines are aged.
Chinon
Chinon is the most important and best-known appellation for Cabernet Franc in the Loire, and arguably the best expression of this grape as a single-variety wine anywhere in the world. The wines are light to medium-bodied with red cherry, raspberry, green bell pepper, pencil shavings, and a distinctive herbal, leafy quality.
Chinon has diverse soils: gravelly terraces near the river produce lighter, fruitier wines for early drinking, while tuffeau limestone slopes (côteaux) produce more structured, age-worthy reds.
Bourgueil and Saint-Nicolas-de-Bourgueil
Across the river from Chinon, producing similar Cabernet Franc reds. Bourgueil can be slightly more structured and tannic than Chinon. Saint-Nicolas-de-Bourgueil, a sub-appellation within Bourgueil, tends to be lighter and more approachable.
Central Vineyards
The easternmost sub-region of the Loire, and the furthest from the ocean. This is Sauvignon Blanc country: home to two of the most famous Sauvignon Blanc appellations in the world.
Sancerre
Sancerre is the French benchmark for Sauvignon Blanc. The wines are dry, crisp, and intensely aromatic, with gooseberry, citrus, green apple, grassy/herbaceous notes, and a distinctive flinty minerality. The best examples have a wet-stone or gunflint character that comes from the Kimmeridgian limestone and flint (silex) soils.
Soils matter here: Sancerre has three main soil types, each producing a subtly different style:
- Silex (flint): produces the most mineral, flinty, long-lived wines
- Kimmeridgian limestone/marl (terres blanches): produces fuller, rounder wines with good structure
- Caillottes (stony limestone): produces lighter, more immediately fruity wines
Sancerre also produces a small amount of red and rosé wine from Pinot Noir. These are light-bodied and cherry-scented, pleasant but not the main attraction.
Pouilly-Fumé
Directly across the river from Sancerre. Also 100% Sauvignon Blanc. The name "fumé" (smoky) refers to the wine's characteristic smoky, gunflint quality, attributed to the flint-rich soils. The style is similar to Sancerre but often considered slightly more full-bodied and mineral, with a smoky depth.
Important distinction: Do not confuse Pouilly-Fumé (Sauvignon Blanc from the Loire) with Pouilly-Fuissé (Chardonnay from Burgundy). This is a classic exam trap, they sound similar but are completely different wines from different regions.
Menetou-Salon, Quincy, and Reuilly
Three smaller Central Vineyard appellations producing Sauvignon Blanc in a similar style to Sancerre, often at lower prices. Menetou-Salon also produces some Pinot Noir red. These are "value" alternatives to Sancerre and worth knowing as budget-friendly study wines.
Exam Tip
Sancerre and Pouilly-Fumé are the French benchmark for Sauvignon Blanc. If the exam asks you to compare Sauvignon Blanc styles globally, use Sancerre as the Old World reference point (mineral, restrained, unoaked) vs Marlborough, New Zealand as the New World reference (tropical, pungent, also unoaked). Know what distinguishes them: climate, soil influence, and aromatic intensity.
Sparkling Wines of the Loire
The Loire is France's second-largest producer of sparkling wine after Champagne, and the traditional method is used throughout. The tuffeau limestone caves of the Saumur area provide perfect cellar conditions for ageing sparkling wine.

Pull these from your kit: gooseberry, lemon, green apple, honey, red cherry, green bell pepper. Group them: gooseberry + lemon = Sancerre Sauvignon Blanc; apple + honey = Vouvray Chenin Blanc; red cherry + green bell pepper = Chinon Cabernet Franc. This three-way contrast is the essence of the Loire.
Wine drill: Taste a Sancerre, a Vouvray (demi-sec if possible), and a Chinon side by side. Three completely different wines from one river valley. Write SAT notes for each and notice how high acidity is the common thread despite the different grapes, colours, and sweetness levels.
What the Exam Expects You to Know
- The four main sub-regions and the climate gradient from maritime (west) to continental (east)
- Muscadet: grape (Melon de Bourgogne), sur lie ageing, and why it matters
- Chenin Blanc's versatility in Anjou-Saumur and Touraine (dry, off-dry, sweet, sparkling)
- The key Chenin appellations: Savennières (dry), Vouvray (all styles), Coteaux du Layon (sweet)
- Cabernet Franc in the Loire: Chinon and Bourgueil as single-variety expressions

Short Answer Strategy
The Loire is a "versatility" region. If asked about it, structure your answer geographically (west to east) or by grape variety. Show that you understand the climate gradient and how it determines which grapes are grown where. And always come back to acidity: it's the unifying theme of every Loire wine.
