Riesling — The Noble Grape of Germany and Alsace
Riesling's origins are in the Rhine Valley, documented in records from 1435 at Rüsselsheim. The grape's name may derive from 'riessen' (to tear) referring to its tendency to split. The Mosel's steep slate terraces, planted with Riesling since Roman times, remain the variety's spiritual home. Mosel wine was Germany's most valuable export for centuries; Johannes Gutenberg reportedly preferred it. The first documented Spätlese was from Schloss Johannisberg in 1775.
Riesling is widely considered by wine professionals to be the world's greatest white grape variety — capable of producing the driest, most age-worthy dry whites (Alsace Grand Cru, Wachau Smaragd, Clare Valley Dry), the most complex and long-lived semi-sweet wines (German Spätlese and Auslese), and the most transcendent sweet wines ever produced (Trockenbeerenauslese, which can age for 50–100 years). Unlike almost every other variety, Riesling's quality is not determined by winemaking intervention — the grape's natural high acidity, low alcohol (8–12% in many European expressions), and intense aromatic complexity (citrus, stone fruit, slate, petrol) speak entirely for themselves with no oak, no malo, and minimal manipulation. Germany's Mosel, Rhine Rheingau, and Rhinehessen regions; Alsace's Grand Crus in France; and Australia's Clare and Eden Valleys represent the diversity of the world's finest Riesling expressions. The characteristic 'petrol' note (TDN — 1,1,6-trimethyl-1,2-dihydronaphthalene) that develops with bottle age is a complexity indicator, not a flaw.
