Germany — Riesling, the Mosel, and the World's Greatest Sweet Wines

Germany produces the world's finest Riesling — wines of extraordinary precision, the most complex expression of the grape from dry Spätlese to the impossibly concentrated Trockenbeerenauslese. The Mosel, with its dramatic slate river bends and pencil-thin rows of vines clinging to near-vertical slopes, is one of the most visually stunning and historically significant wine regions on earth.

Geography

Germany's 13 wine-growing regions (Anbaugebiete) are all in the country's warmer south and west. The major zones:

• Mosel — the most famous; the Mosel River and its tributaries Saar and Ruwer; slate soils; the benchmark for light, delicate Riesling
• Rheingau — the bend of the Rhine; south-facing slope opposite Wiesbaden; more powerful, drier Riesling style; see separate article
• Rheinhessen — Germany's largest region; diverse; source of Liebfraumilch (historic) and some excellent Riesling and Spätburgunder
• Pfalz — warm, diverse; excellent Riesling and increasingly important Spätburgunder (Pinot Noir)
• Nahe — small, diverse; excellent quality, underrated
• Baden — Germany's warmest zone; strong Spätburgunder tradition; southernmost

The Praedikat System

Germany's wine classification is based on the ripeness (sugar content) of the grapes at harvest, measured in degrees Oechsle. This is the Praedikatswein system:

Trocken / Halbtrocken / Feinherb: Modern German wine also uses dryness level labels: Trocken (dry, max 9 g/L RS), Halbtrocken (medium-dry, 9–18 g/L), Feinherb (a looser term for gently off-dry). Many top Riesling producers now produce fully dry expressions.

GG (Grosses Gewächs): The VDP (a producer association) designation for dry wines from classified single vineyards — Germany's equivalent of Grand Cru for dry wines.

The Mosel

The Mosel (and its tributaries Saar and Ruwer) is Germany's most famous wine region. The unique combination:

• Blue Devonian slate soils that retain heat and reflect light onto vines
• Extreme southerly-facing slopes (some at 65–70°) that maximise sun exposure
• The river's thermal moderating effect
• The cool continental climate that preserves acidity even in ripe grapes

The result: Riesling of extraordinary delicacy and precision — the lowest alcohol of any fine wine region (7–9% for Kabinett), combined with the highest natural acidity. The tension between sweetness and acidity is the Mosel's signature.

Key villages: Bernkastel (Bernkasteler Doctor), Piesport (Goldtröpfchen), Wehlen (Wehlener Sonnenuhr), Erden (Erdener Treppchen), Ürziger Würzgarten, Brauneberger Juffer.

Famous Producers

Mosel:

• J.J. Prüm — the most revered Mosel estate; Wehlener Sonnenuhr; ethereal Spätlese and Auslese
• Egon Müller — Scharzhofberg (Saar); TBA prices match Pétrus; the world's most expensive Riesling
• Weingut Mosel (formerly Fritz Haag) — Brauneberger Juffer; excellent across all levels
• Willi Schaefer — small, meticulous; Graacher Domprobst and Himmelreich; consistently extraordinary
• Dr. Loosen — reliable quality; good international distribution; excellent value

Rhine:

• Georg Breuer — Rheingau; benchmark dry Riesling
• Robert Weil — Rheingau; remarkable Auslese and above from Kiedricher Gräfenberg

Wine Styles

Mosel Kabinett/Spätlese: The most ethereal expressions in world wine. As light as 7.5% ABV, yet with extraordinary complexity from the tension of grape-sugar sweetness and piercing slate-mineral acidity. Peach, apricot, lemon, floral, slate. Drink 5–30 years from top estates.

Auslese: Richer, more concentrated. Begin to show botrytis influence. Honey, apricot, lemon curd, ginger.

TBA and BA: Among the world's greatest sweet wines. Honey, marmalade, saffron, incredible complexity. Decades of ageing ahead. Produced only in finest years.

Making German-Style Riesling

Approach

German Riesling can be made dry (Trocken) or with residual sugar from any Riesling clone. The goal is maximum aromatic precision and minerality.

Harvest

• For Kabinett style: harvest at 21–22°Bx; target pH 2.9–3.1; TA 9–12 g/L.
• For Spätlese: 23–24°Bx.
• Cool nights and meticulous vineyard selection are essential.

Fermentation

• Cool (12–14°C) is mandatory for Riesling. Warm fermentation destroys the delicate aroma.
• Yeast: Oenoferm Cool or VL3 — both designed for aromatic preservation at low temperatures.
• For off-dry styles: arrest fermentation when desired RS is reached by dropping temperature to 0–4°C, then filter and cold stabilise.
• For dry styles: ferment to dryness; the balance then comes from the natural high acidity.

Ageing

• Stainless steel or large neutral oak (traditional Fuder — 1,000L oval casks) for best examples.
• No malolactic fermentation — ever. Malic acidity is structural and essential to Riesling's character.
• Bottle with 35–40 mg/L total SO₂ to protect during ageing.

Food Pairing

Mosel Kabinett: Asian cuisine (Thai, Vietnamese), sushi, delicate white fish, fresh cheeses.
Spätlese/Auslese (off-dry): rich pâtés, blue cheese, spiced pork dishes.
TBA/BA: alone as a meditation; or with aged hard cheeses and bitter dark chocolate.
