Riesling

Character & Identity

Ask any group of sommeliers which grape they would drink if they could only choose one, and Riesling will win the vote more often than any other. The reasons are not hard to find. No other grape combines such searingly high acidity with such vibrant aromatic personality, such a wide range of sweetness levels, and such profound ageing potential — all at alcohol levels that remain civilised (often 8–10% abv) where most serious wines are pushing 14%. Riesling is the grape that makes wine writers reach for superlatives while remaining, somehow, the world’s most underrated variety in the mainstream market.

In youth, Riesling offers laser-precise citrus — lime, lemon, green apple — alongside white peach, pear, and floral notes of jasmine or white blossom. On slate-heavy soils, there is a mineral quality that sommeliers describe as “wet stone” or, more evocatively, “licking a riverbed.” The famous “petrol” note — technically 1,1,6-trimethyl-1,2-dihydronaphthalene, or TDN — develops with age and is caused by the breakdown of carotenoids in the skin. It is to Riesling what earthiness is to Pinot Noir: a mark of maturity, not a flaw. Newer, cooler vintages from high-altitude sites often produce TDN-free wines; warmer vintages and older bottles develop it irresistibly.

Key Regions & Expressions

The Mosel is Riesling’s heartland and produces what many consider the most precise, most ethereal white wines on the planet. The steep, slate-terraced vineyards — some at angles of 60 degrees or more — force vines to send roots deep into mineral-rich subsoil, while the river moderates temperature extremes and reflects sunlight upward. Mosel Rieslings are featherlight in body, rarely above 9% abv, and balance delicate fruit sweetness (even in ostensibly “dry” Kabinett wines) against almost electric acidity. Great producers — Egon Müller, J.J. Prüm, Dönnhoff — produce wines that warrant decades of cellaring.

Alsace, directly across the Rhine from Germany, produces a radically different expression: fuller-bodied, more phenolic, often completely dry, and frequently fermented to 13–14% abv. Alsace Grand Cru Riesling from limestone-dominant sites like Schlossberg or Brand is among the world’s most powerful and age-worthy dry whites. Australia’s Clare and Eden Valleys produce superb expressions under screwcap — lime cordial, slate, and lanolin — that age gracefully for fifteen-plus years. Austria’s Wachau, New York’s Finger Lakes, and Germany’s Rheingau all add significant chapters to the variety’s story.

Ageing & Structure

The combination of high acidity, moderate to low alcohol, and significant residual sugar (in classic German styles) gives Riesling ageing potential that borders on the miraculous. A Mosel Auslese from a great vintage — Egon Müller’s Scharzhofberger, say — will peak somewhere between fifteen and forty years after harvest. At that point, the wine is something altogether different from what went into the bottle: golden in colour, honeyed and complex with beeswax, dried apricot, truffle, and that haunting petrol note, yet still underpinned by laser-bright acidity that keeps it alive and vibrant.

For everyday drinking, even modest Kabinett and Spätlese wines show real development over three to eight years — it is worth buying a case rather than individual bottles to track their evolution. Dry styles (labeled Trocken in Germany) generally mature faster than sweeter examples, because residual sugar acts as a natural preservative. Alsace Riesling sits between these poles. Under screwcap, Clare Valley Riesling is famous for the way it develops over a decade: the zippy primary lime of youth giving way to a beautiful, kerosene-tinged, toasted complexity that rewards those patient enough to wait.
