Germany makes wine at the very northern edge of where the vine can ripen, on slopes so steep they must be worked by hand. From this improbable frontier comes Riesling — for many critics the most nuanced white grape on earth — along with a uniquely German idea: that a wine should be classified not by region alone, but by exactly how ripe its grapes were when picked1.
Quick facts
- The Romans planted vines along the Mosel and Rhine nearly two thousand years ago.
- Riesling is Germany’s flagship grape; its first written mention dates to 1435.
- The Spätlese (late harvest) was, by legend, discovered by accident in 1775.
Rome’s northern frontier
Wine came to Germany with the Roman legions, who planted the banks of the Mosel and Rhine to supply the frontier city of Trier. The vine took to the cool, steep river valleys, and after Rome fell it was the Church that kept viticulture alive through the Middle Ages. Germany became, and remains, the northernmost of the classic wine countries — a place where ripeness is never guaranteed and every sunny slope is precious1.
Riesling, king of the slate



The grape that made Germany famous is Riesling, first recorded by name in a cellar account of 1435. On the dark slate of the Mosel and the sun-catching hills of the Rheingau, it ripens slowly and holds on to a piercing acidity, giving wines that can be bone-dry or lusciously sweet yet always taste of their stony ground. Few grapes reflect their terroir so faithfully, or age so gracefully over decades2.
The monks and the first Riesling estate
No place tells the story better than Schloss Johannisberg in the Rheingau, where vines have grown since 817. In 1720 its slopes were replanted entirely with Riesling, making it the first estate in the world devoted to the grape. Perched above the Rhine, its Benedictine cellars became a laboratory for German wine — and the setting for its most famous accident3.
The messenger who came late
By tradition, the pickers at Schloss Johannisberg could not begin the harvest until a messenger returned from the abbot with formal permission. In 1775, the story goes, the rider was badly delayed, and by the time he arrived the grapes had shrivelled and grown mouldy with noble rot. The monks pressed the ruined-looking fruit anyway — and made a wine of astonishing sweetness and depth. The Spätlese, or “late harvest,” was born, and Auslese and the even sweeter styles soon followed4.
The grapes were shrivelled and rotten — and made the finest wine anyone had tasted.— the Spätlese legend, Schloss Johannisberg, 17754
A ladder of ripeness
That discovery shaped the whole German system. Rather than rank wines by vineyard alone, Germany grades them by the ripeness of the grapes at harvest — a ladder rising from Kabinett through Spätlese and Auslese to the intensely sweet Beerenauslese, Trockenbeerenauslese and frozen-grape Eiswein. Codified in the German Wine Law of 1971, this Prädikat system is unlike any other in the wine world5.
Crash and revival
Germany’s reputation nearly drowned in sugar. In the later twentieth century, floods of cheap, semi-sweet Liebfraumilch — think Blue Nun — taught the world to dismiss German wine as sweet and simple. The backlash sparked a revival: a new generation turned to bone-dry (trocken) Rieslings and top “Grosses Gewächs” bottlings under the growers’ association, the VDP, restoring Germany to the front rank of fine white wine6.
