What is the main characteristic that defines German Riesling across most regions?

• A. Low acidity and high tannin
• B. Neutral profile with minimal aging potential
• C. Predominant oak influence with vanilla notes
• D. High acidity and the potential for mineral, citrus, and floral notes with aging

Answer: (D)

High acidity anchors German Riesling across most regions. The cool climate and often slate soils give Riesling bright, persistent acidity that keeps the wine lively and forms the backbone for aging. As it ages, Riesling develops mineral or slate-like character along with citrus and floral notes, becoming more expressive over time. This combination of high acidity with aging potential and those evolving flavor notes is what defines the style in Germany. The other profiles—low acidity with tannin, a neutral profile with little aging potential, or heavy oak influence—don’t fit the typical Riesling profile in German regions.
