Keller's 2017 Riesling G-Max shows a clear nose with ripe, concentrated fruit and saline notes of crushed rocks and already indicates a fine tannin quality. Elegant and juicy on the palate, this is a very dense and firmly structured dry Riesling with concentrated fruit and a still somewhat phenolic structure that is even astringent on the finish. It has a currently slightly untamed character that is reminiscent of game. It is still inaccessible but a promising G-Max with power and structure that needs a lot of patience (or another decade in the bottle). Tasted blind as wine number 19 in this historic G-Max vertical at Steinheuer's Restaurant Zur Alten Post in Bad Neuenahr-Ahrweiler, January 2024.
