In the intense world of blind tasting, Riesling is supposed to be a "banker"—a grape so aromatic and distinct that its identity should be immediate and confident. But while the structural markers of high acidity, low alcohol, and zero new oak are constant, the real challenge lies in untangling its global terroir. Drawn straight from Master of Wine exam preparation notes, this comprehensive profile breaks down the precise anatomical blueprints of Riesling. From the ethereal, slate-driven off-dry styles of the Mosel to the broad, savory oiliness of Alsace and the bone-dry, lime-slicked structures of Australia's Clare Valley, this is your ultimate guide to nailing regional nuances and avoiding common tasting pitfalls.
