Spätlese Riesling is one of the categories for late-harvest German Riesling wines. It falls under a broader category of Prädikatswein—which is a classification based on the ripeness level at which the grapes are harvested.
Apart from Spätlese, this category also includes Kabinett (the least amount of sugar), Auslese, Beerenauslese, Trockenbeerenauslese, and Eiswein. Spätlese is made from fully ripe grapes, and it is the lightest variety of late harvest wines.
If the fermentation is stopped early, the wines will have a sweeter profile and more amounts of residual sugar, while longer fermentation results in drier wines. Some will also have the additional labeling—spätlese trocken for bone dry wines and spätlese halbtrocken for off-dry, slightly sweet wine.
Alcohol level can also suggest the character of these wines. If the ABV falls around or under 11%, these wines will typically be medium-dry. As Riesling is generally packed with bright acidity, Spätlese wines are lively, fresh, and well-balanced.
