A Guide to the Alsace Wine Classification System

Alsace runs one of the simplest appellation structures in France. Two classifications cover the still wines: Alsace and Alsace Grand Cru. That’s most of what you need to read a shelf or wine list. The complication shows up further down the label, where a wine starts telling you how much sugar the grapes had when they were picked.

How Alsace Labels Its Wine

Alsace labels by grape, not by place. A Burgundy bottle names the vineyard and trusts you to know what grows there; an Alsace bottle names the grape itself, and when it does, the wine is 100 percent that variety. Riesling, Muscat, Gewurztraminer, Pinot Gris: these are the four noble varieties, and the wines worth paying attention to are single-variety bottlings of one of them. Blends happen too, and they carry their own terms, more on that below.

Terms With No Legal Weight

You’ll sometimes see Réserve Personnelle or Cuvée Spéciale on a label. Ignore them; they carry no legal standing in the classification system. It’s just a producer’s own way of saying “this one’s special,” not a rule you need to track.

The Two Classifications

Alsace AOC

This is the workhorse, most of what the region actually bottles. The grape name goes on the label, occasionally with a village name added alongside it.

Alsace Grand Cru

Above Alsace AOC sits Alsace Grand Cru: as of 2026, more than 50 vineyards carry their own Grand Cru classification, each a named site with its own rules. A Grand Cru has to come from a single noble variety, and the label has to show four things: the vineyard name, the vintage, the grape, and the words “Grand Cru” itself.

The Sugar Terms

Either kind of wine, Alsace or Grand Cru, can also carry one of two sugar-level terms.

Vendanges Tardives (VT)

VT means late harvest, and what earns the label is a minimum sugar level in the grapes at picking, measured there rather than judged later in the glass. The floor depends on the grape: 235 grams per liter for Muscat and Riesling, 257 for Pinot Gris and Gewurztraminer, and only those four noble varieties qualify at all. In the best VT wines, the fruit has raisined right on the vine, concentrating sugar, acid, and flavor together. Botrytis might play a part, but VT doesn’t require it.

Sélection de Grains Nobles (SGN)

SGN does require botrytis, the noble rot, and the sugar minimums climb to match it: 276 grams per liter for Muscat and Riesling, 306 for Pinot Gris and Gewurztraminer. The real difference between the two isn’t sweetness, it’s how the grapes got there: VT dries on the vine, SGN gets there through rot.

The Blend Terms

Two everyday blends round out the system. Gentil has to be at least half noble varieties, with the rest coming from any other Alsace grape, so it still keeps a foot in the serious camp. Edelzwicker has no such rule; it’s the everyday table blend, priced to match.

Crémant d’Alsace

The region’s sparkling wine, and often the best value on the list. Pinot Blanc usually leads the blend, Pinot Noir (the only red grape allowed in Alsace AOC) sometimes joins it, and Crémant is the one Alsace appellation where Chardonnay is allowed in at all, a grape that otherwise has no home here.

The two-classification system still holds, but it’s not the whole story on its own. The rank tells you the tier, the sugar terms tell you how the wine was made, and the blend terms tell you how seriously to take what’s in the bottle. Read the label in that order, and it all falls into place.
