Liebfraumilch is usually produced from Müller-Thurgau.

• A. Riesling
• B. Silvaner
• C. Müller-Thurgau
• D. Grauburgunder

Answer: (C)

This question tests which grape variety most commonly forms the base of Liebfraumilch, a semi‑sweet white wine from the Rhine region. Müller-Thurgau is the classic backbone for this style because it ripens early and yields a light, fruity wine with gentle acidity. That low-to-mid acidity plus fruity character balances the residual sugar that characterizes Liebfraumilch, delivering the smooth, easy-drinking profile the label is known for.

Other varieties listed can appear in German whites, but they don’t define this label as reliably. Riesling brings more pronounced acidity and aroma, Silvaner has a subtler, earthier note, and Grauburgunder offers more body—none align as consistently with the semi-sweet, approachable style as Müller-Thurgau.
