Part of the confusion among those less familiar with German wine is the classifications of the Prädikat. Most exported wines are of Qualitätswein mit Prädikat (QmP) quality, which certifies the characteristics of the grape must used to produce the wine. This form of classification does not specify the characteristics of the final wine, but simply controls for the concentration of sugars in the must (must weight). Therefore, there can be variation in sweetness and alcohol levels due to how completely the must is fermented and other preferences of the winemaker. While the six classifications provide a good indication of the degree of residual sugars and the quality of the grapes with which the wine was produced, the classification system permits significant variation in winemaking style and often blurs the lines that separate the various categories.
- Kabinett wine is produced from young grapes that are lower in must weight and generally suggest a lighter wine with subtle, more delicate flavors. Often these wines are dry with little residual sugar.
- Spätlese wine is made from grapes that have spent more time on the vine and developed a higher sugar concentration, as the translation of “late harvest” suggests. These wines generally have a higher concentration of residual sugars but still retain the distinctive and complex flavors of the famed Riesling.
- Auslese, translated as “select harvest”, is also late harvest wine that is produced from select bunches of grapes with higher sugar concentrations than Spätlese. Generally, the selective nature of the component grapes produces a higher quality of wine than Spätlese and often is richer in flavor and character.
- Beerenauslese, or “selected grapes”, refers specifically to wine made of individually selected grapes that affected by the botrytis fungus (also known as noble rot) where the grape is shriveled and dehydrated creating intensely concentrated flavors and sweet wines similar to those produced in the Sauternes region of Bordeaux and the Tokay region of Hungary.
- Trockenbeerenauslese, or “dry berry selection”, must be made from grapes shriveled by the botrytis fungus and are required to have an Oechsle value of 150 or higher (designating the concentration of sugar). These are often amber colored wines that are thicker due to the high sugar content and can have high alcohol levels.
- Eiswein, of simply “ice wine”, are made from grapes that are among the last to be harvested and have literally been frozen by the winter temperatures. The frozen grapes are brought to the winery in December or January to be pressed before thawing, with the resulting juice highly concentrated and rich in sugar and acids. By separating the ice crystals from the flavorful juice, the eiswein process creates a rich, concentrated, sweet wine that is often an expensive, yet pleasurable, treat.
In addition to the classification system, confusion emerges from the German labeling rules which allow producers to mislead potential customers with designations that suggest theirs is a single vineyard wine from a highly desirable location when instead it is a lower quality regional wine with grapes drawn from potentially a number of inferior vineyards in the area. While the price will likely give away the quality, the only recourse consumers have is to familiarize themselves with the leading producers and vineyards of the region.
In my upcoming trip to the Mosel River Valley, I will be traveling to three of the top wineries to sample their wines and reflect upon the intricacies of exquisite German Riesling. Reviews of their offerings can be found by following the links below.
- Dr. Loosen, Bernkastel-Kues, Germany
- Weingüter Mönchhof & Joh. Jos. Christoffel Erben, Ürzig / Mosel, Germany
