What is Gmax?

• A. Germany's most expensive Riesling produced by Weingut Keller, marketed as G-Max.
• B. A Riesling from a single vineyard by a different producer.
• C. A red wine from Rheinhessen.
• D. G-Max is the micro-production Riesling from Keller with an undisclosed vineyard site in Rheinhessen.

Answer: (D)

G-Max is Keller’s ultra-limited Riesling produced in a tiny quantity, with the vineyard site intentionally kept secret in Rheinhessen. This combination—extremely small production and an undisclosed source—defines what G-Max is. It’s a white wine from Keller, not a red, and not from a different producer, which is why the option describing it this way is the most accurate. The other choices either imply a different producer, a red wine, or a publicly identified single vineyard, none of which matches Keller’s G-Max concept.
