Named in honour of his great-grandfather Georg and his youngest son Max, Keller's 2015 G-Max is the most in need of serious cellaring of all his dry Rieslings. Notes of lemon, wet stones, fresh bread and white flowers introduce an extraordinarily three-dimensional, complete wine which stains the palate with minerality and lingers through an impossibly long finish. Simply the pinnacle of dry Riesling - and the only thing that keeps the Morstein and Abtserde from receiving a perfect score.

A powerful and extremely citrusy, focused dry riesling with stacks of drive for the very warm vintage. Still very tense on the concentrated, medium- to full-bodied palate. The great freshness at the finish suggests this wine is still not at its peak. Shows much better than when first tasted on release. Drinkable now, but best from 2025. At the Keller G-Max vertical tasting. - Stuart Pigott

(94 - 96) The iconic 2015 Riesling G-Max offers a deep, clear, pure and intense bouquet of ripe seed, stone and a touch of tropical fruits that is perfectly intertwined with smoky crushed limestone, herbal and floral flavors. Dense, round, tight and vivacious on the palate, this is a very pure and mineral Riesling of great finesse and elegance. It is a dense and very complex, yet perfectly balanced, long and stimulatingly salty wine with an intense and persistent fruit core. A perfect blend of earlier and late harvested grapes that were slowly pressed with the basket press, like all of the crus and sweet wines at Keller.- SR

Ripe, pit-inflected peach and mirabelle are accented on the nose by smoky suggestions of peat. More typical chalkiness ensues inner-mouth, with broadly palate-saturating pit fruit flavors allied to animating (analytically over 9 grams) acidity experienced as infectiously juicy lime and grapefruit. An incisive crunch of mustard seed adds to the nearly detonative intensity and grip of this palpably extract-rich Riesling’s finish.-DS
