Section 3 · Still Wines of the World
Alsace
Alsace is France's most important region for aromatic white wines and the only major French region where varietal labelling is the norm. Tucked between the Vosges mountains and the Rhine river on the German border, Alsace produces intensely flavoured whites that stand apart from every other French wine region in both style and labelling tradition.

Why Alsace Matters
Alsace is a region of contradictions for anyone studying French wine. While the rest of France labels wine by appellation and terroir, Alsace puts the grape variety front and centre on the label. While most French white wine regions focus on Chardonnay or Sauvignon Blanc, Alsace champions aromatic grapes like Riesling, Gewürztraminer, and Pinot Gris. And while its geographic position might suggest a cold, marginal climate, the Vosges mountains create a unique rain shadow that makes Alsace one of the driest, sunniest wine regions in France.
For the WSET Level 3 exam, Alsace matters because it tests your understanding of how geography creates a microclimate, how varietal labelling works differently from the rest of France, and how a single region can produce wines ranging from bone-dry to lusciously sweet, sometimes with confusing ambiguity in between.
Alsace Wine Map
Tap or hover over any area to see its key details. Alsace stretches along a narrow strip between the Vosges mountains and the Rhine river.
Geography and Climate
Alsace occupies a narrow strip of vineyards along the eastern foothills of the Vosges mountains in north-east France, directly across the Rhine from Germany. The region stretches approximately 170 kilometres from north to south but is rarely more than a few kilometres wide, the vineyards are squeezed between the mountains to the west and the flat Rhine plain to the east.
The Vosges Rain Shadow
This is the single most important geographic fact about Alsace. The Vosges mountains rise to around 1,200 metres and act as a barrier to the moist westerly winds blowing in from the Atlantic. As the air masses hit the mountains, they rise, cool, and drop their moisture as rain on the western slopes. By the time they descend into the Alsace vineyards on the eastern side, the air is dry.
The result: Alsace is one of the driest wine regions in all of France, with just 500–600mm of rainfall per year in the vineyard zones around Colmar (compared to about 800mm in Burgundy and over 900mm in Bordeaux). This low rainfall, combined with long, sunny autumns, allows grapes to hang on the vine well into October and November, building exceptional ripeness and aromatic concentration.
Continental Climate
Despite its sheltered position, Alsace has a continental climate with warm summers and cold winters. The key features for viticulture are:
- Warm, dry summers: long sunshine hours and low rainfall promote slow, even ripening
- Cool nights: the continental temperature swing between day and night preserves acidity in the grapes, which is why Alsace wines maintain freshness despite their aromatic richness
- Cold winters: can cause frost damage, though the vineyards on the foothills benefit from air drainage that reduces frost risk compared to the valley floor
- Long, dry autumns: critical for late-harvest styles (Vendange Tardive and Sélection de Grains Nobles)
Soils
Alsace has an unusually diverse range of soils due to complex geological history. Within a short distance, you can find granite, limestone, sandstone, marl, clay, schist, and volcanic rock. This diversity is one of the justifications for the Grand Cru system, different soil types on different slopes give genuinely distinct expressions from the same grape variety.
- Granite: produces elegant, mineral-driven wines with fine structure (e.g., Grand Cru Schlossberg)
- Limestone and marl: gives broader, richer wines with weight and power
- Sandstone: lighter, more delicate wines with bright fruit
- Volcanic: adds a smoky, flinty mineral character (e.g., Grand Cru Rangen)
Exam Angle
If asked about Alsace's climate, always connect the Vosges rain shadow to the wine style. The chain is: Vosges block rain → dry, sunny conditions → long growing season → fully ripe aromatic grapes → intense, concentrated wines. This cause-and-effect explanation is exactly what earns marks.
Varietal Labelling: The Alsace Exception
In almost all of mainland France, wine labels emphasise the place of origin (the appellation) rather than the grape variety. Burgundy labels say "Chablis," not "Chardonnay." Bordeaux labels say "Pauillac," not "Cabernet Sauvignon." The philosophy is that terroir matters more than grape variety.
Alsace is the great exception. Here, the grape variety is the primary identifier on the label. A bottle of Alsace wine will prominently display "Riesling," "Gewürztraminer," "Pinot Gris," or whichever grape it's made from. The appellation (AC Alsace) is there, but the grape name is what catches your eye.
The Appellation System
Grape Varieties
Alsace is defined by its grape varieties more than any other French region. The grapes fall into two tiers: the four "noble" varieties (which can appear on Grand Cru labels) and the supporting cast.
The Four Noble Grapes
Riesling
Considered the finest grape in Alsace and the region's flagship variety. Alsace Riesling is typically drier and more full-bodied than German Riesling, with pronounced citrus (lime, lemon), green apple, and white flower aromas. Young wines are steely and precise; aged examples develop the distinctive petrol (kerosene) note that is a hallmark of mature Riesling worldwide.
Key characteristics: High acidity (even when fully ripe), bone-dry to off-dry, mineral character that reflects the soil type, excellent ageing potential. The best Grand Cru Rieslings can age for 20+ years.
Style range: From racy, lean wines on granite to broader, richer wines on limestone. The majority are dry or near-dry, though late-harvest versions exist.
Gewürztraminer
The most instantly recognisable wine in Alsace, and arguably in the world. Gewürztraminer produces explosively aromatic wines with lychee, rose petal, Turkish delight, ginger, and exotic spice. The name itself means "spiced Traminer" (gewürz = spice in German).
Key characteristics: Naturally low acidity, high alcohol potential (often 13.5–14.5%), deep golden colour, full body. Even when technically dry, Gewürztraminer can taste off-dry because of its rich texture and low acidity. This grape divides opinion, some people find it overwhelming, others find it glorious.
Food pairing note: A classic match for spicy Asian cuisine (Thai, Indian), foie gras, and Munster cheese (the local Alsatian washed-rind cheese).
Pinot Gris
Produces the richest, most full-bodied dry whites in Alsace. Pinot Gris here is a completely different proposition from Italian Pinot Grigio, where Pinot Grigio is light and neutral, Alsace Pinot Gris is weighty, smoky, and complex, with aromas of honey, beeswax, pear, and sometimes a subtle spiciness.
Key characteristics: Medium acidity, full body, high alcohol potential. Can be vinified dry or off-dry. Often has a slight golden hue and a richly textured, almost oily mouthfeel.
Exam note: Alsace Pinot Gris was historically labelled "Tokay d'Alsace" or "Tokay-Pinot Gris," but this name was phased out to avoid confusion with Hungarian Tokaji. You might still see older bottles with the Tokay name.
Muscat
The only one of the four noble grapes that is typically vinified completely dry in Alsace, which sets it apart from most Muscat wines worldwide, which tend to be sweet or sparkling. Alsace Muscat smells exactly like fresh grapes and orange blossom, but on the palate, it's dry and crisp. This grape-juice-that-isn't-sweet quality is its charm.
Two types used: Muscat Blanc à Petits Grains (more aromatic, finer quality) and Muscat Ottonel (less intense, earlier ripening). Both are permitted and often blended together.
Production note: Muscat is the least planted of the four noble grapes. It's sensitive to poor weather and can be tricky to grow, so volumes are small.
Other Permitted Varieties
Pinot Blanc
The workhorse white grape of Alsace. Clean, apple-and-pear flavoured, medium-bodied, and easy-drinking. Often used as the base for Crémant d'Alsace. Think of it as Alsace's version of a house white, pleasant, reliable, and affordable. Technically, "Pinot Blanc" on an Alsace label may also include the related variety Auxerrois, which adds a slightly richer, rounder character.
Sylvaner
A light, neutral, high-acid white. Once widely planted but declining in favour. Simple, lemony, and best drunk young. Rarely seen outside Alsace and Germany. Not considered a noble grape, so generally excluded from Grand Cru (with one exception: Grand Cru Zotzenberg permits Sylvaner).
Pinot Noir
The only red grape permitted in Alsace. Historically produced light, pale rosé-like reds, but climate change and better winemaking have brought more serious, darker Pinot Noirs in recent years. Some producers now use oak ageing to make structured reds reminiscent of lighter Burgundy. Quality is rising, but Alsace Pinot Noir is still generally lighter than Burgundy's best.
Exam Tip
Know the four noble grapes cold: Riesling, Gewürztraminer, Pinot Gris, Muscat. These are the only varieties permitted for Grand Cru wines and for the Vendange Tardive and Sélection de Grains Nobles designations. If the exam asks what makes Alsace unique in France, the answer is varietal labelling, and these four grapes are at the heart of it.
The Grand Cru System
Alsace has 51 Grand Cru vineyards, each a named site with defined boundaries, specific soil types, and particular exposures. The Grand Cru designation was officially established in 1975 and has been expanded over time.
Rules for Grand Cru Wines
- Only the four noble grapes are permitted (Riesling, Gewürztraminer, Pinot Gris, Muscat), with very limited exceptions
- Single-variety wines only: no blending of grape varieties (again, with rare exceptions)
- Lower maximum yields than basic AC Alsace
- Higher minimum ripeness levels at harvest
- Hand harvesting required
- The vineyard name must appear on the label
Notable Grand Cru Sites
Vendange Tardive and Sélection de Grains Nobles
Beyond the dry and off-dry wines, Alsace produces two legally defined categories of sweet wine that are considered among France's finest. Both use only the four noble grapes.
Vendange Tardive (VT)
"Late harvest." Grapes are left on the vine well beyond normal harvest time to achieve very high sugar levels. The resulting wines are rich and concentrated, though they may range from off-dry to fully sweet depending on how much sugar the yeast ferments. There is no requirement for botrytis, though it may be present.
Minimum sugar at harvest: Specified by grape variety, highest for Gewürztraminer and Pinot Gris, lowest for Riesling and Muscat. These are legal minimums set by the appellation rules.
Style: Rich, honeyed, with the grape's characteristic aromatics amplified. VT Riesling keeps its acidity and can be strikingly balanced even with significant sweetness. VT Gewürztraminer is opulent and exotic.
Sélection de Grains Nobles (SGN)
"Selection of noble berries." An even richer, rarer category. Grapes are selected individually, only those affected by noble rot (botrytis cinerea). The sugar concentration at harvest is significantly higher than VT. These wines are always sweet, extremely concentrated, and produced in tiny quantities.
Style: Intensely sweet, with honey, dried apricot, marmalade, candied citrus, and often a distinctive botrytis character (mushroomy complexity). The best SGN wines are comparable to Sauternes in richness and can age for decades.
Production: SGN wines are only made in exceptional vintages when botrytis conditions are ideal. They are rare and expensive.
Exam Tip
The key distinction: VT requires late-harvested, very ripe grapes (botrytis optional). SGN requires botrytis-affected grapes with even higher sugar levels. Both are restricted to the four noble grapes. Know the names in French, examiners expect the proper terms.
The Dry vs Off-Dry Problem
One of the most talked-about issues in Alsace, and one the exam may touch on, is the ambiguity of sweetness levels. Outside of VT and SGN, Alsace wines are generally marketed as dry. But in practice, many wines (particularly Gewürztraminer and Pinot Gris) contain noticeable residual sugar, making them off-dry or even medium-sweet without indicating this on the label.
This happens because:
- The warm, dry climate allows grapes to reach very high sugar levels
- Fermentation sometimes stops before all sugar is converted to alcohol, leaving residual sweetness
- Some producers deliberately leave residual sugar for a richer, rounder style
- There has historically been no legal requirement to indicate sweetness level on the label
Winemaking
Alsace winemaking is relatively straightforward, designed to let the grape variety and vineyard express themselves without heavy intervention:
- Fermentation typically in stainless steel tanks or large old oak casks (foudres). The goal is to preserve the grape's aromatic character, not to add oak flavour.
- No new oak: this is a fundamental principle. Alsace whites are not oaked in the Burgundy or Bordeaux sense. The old oak casks used by some producers are neutral and contribute no flavour.
- Extended lees contact is common, adding texture and complexity without adding oak flavour.
- Malolactic fermentation: variable. Some producers block it to preserve crisp acidity (especially for Riesling); others allow it for a softer style.
- Single-variety bottling: the overwhelming norm. Blends exist (Edelzwicker, Gentil) but are typically entry-level.

Aroma Kit Integration
Alsace Aroma Session (20 min)
Pull these from your kit: lime, lychee, rose petal, ginger, peach, honey. Smell each one individually. Then try to assign each aroma to a grape: lime and petrol = Riesling; lychee, rose, ginger = Gewürztraminer; honey, peach = Pinot Gris. Building these mental associations is key for blind tasting.
Wine drill: Taste an Alsace Riesling next to an Alsace Gewürztraminer. Write a full SAT note for each. The contrast is dramatic, Riesling's precision and acidity vs Gewürztraminer's richness and low acidity. Can you spot the difference in body and aromatic intensity?
Advanced drill: Taste an Alsace Pinot Gris next to an Italian Pinot Grigio. Same grape, completely different wines. This illustrates how climate and winemaking philosophy shape a grape's expression.

Short Answer Strategy
If you get an Alsace question, lead with what makes it unique: varietal labelling, the Vosges rain shadow, aromatic grape varieties. Then connect these to the wine styles. "Alsace's sheltered position in the Vosges rain shadow creates a dry continental climate ideal for fully ripening aromatic grapes like Riesling and Gewürztraminer, producing intensely flavoured, concentrated wines that are labelled by variety rather than appellation, unique in France."
