Morstein is the great dry Riesling site of the southern Rheinhessen, and this is Wittmann's flagship from it — a Grosses Gewächs, meaning the estate's best dry wine from a classified grand cru slope. The vines sit in a five-hectare parcel in the heart of the hillside, on a south-facing incline of up to 20% where heavy clayey marl runs over porous limestone rock, which is why Morstein gives Riesling both weight and cut rather than just one or the other. The Wittmanns have farmed in Westhofen since 1663 and were remarkably early to conviction farming: organic certification in 1990, biodynamic in 2004, well before either was fashionable in Germany. They're also largely responsible for the full-bodied, balanced dry style Rheinhessen is now known for, so this isn't a wine chasing a template — it helped write one. 2021 was what the estate calls a classic Rhine vintage: a long, fine autumn with cool nights that built aromatics while holding onto acidity, and selective picking throughout the harvest. The result is dry Riesling at modest alcohol with real tension, and it will reward a decade or more of patience.
