Which of the following is true about Prädikatswein?

Prädikatswein is indeed characterized by having higher sugar levels than the standard required for other Qualitätswein. This category of wine represents a specific classification in the German wine system that emphasizes quality and the natural ripeness of the grapes, which leads to elevated sugar content. The higher sugar levels are a result of specific harvesting practices and can significantly influence the sweetness and overall character of the wine, making Prädikatswein a distinguished category that includes various levels such as Kabinett, Spätlese, Auslese, and more.

In contrast, the other choices do not accurately represent Prädikatswein. It is not the lowest category of German wines; that distinction goes to simpler table wines. Additionally, Prädikatswein is predominantly made from traditional German grape varieties like Riesling, Silvaner, and Gewürztraminer, rather than international grape varieties. Lastly, there is no requirement for Prädikatswein to be made from organic grapes, making that statement incorrect as well. The focus on the higher sugar levels is what firmly places Prädikatswein in its distinguished position within the German wine classification system.
