2006 Germany & Mosel Riesling Vintage

The 2006 growing season in Germany was defined by dramatic swings rather than uniform warmth. Winter arrived late, and a cold, wet March gave way to a warm spring and exceptional heat in June and July, raising fears of another 2003-style vintage. August then reversed course entirely, turning unusually cool and wet, which slowed sugar accumulation, raised acidity levels, and created conditions favorable to fungal disease. The decisive moment came in late September, when rain played havoc with already ripe grapes and botrytis spread rapidly across the Mosel and other regions. Producers who reacted quickly and harvested selectively were rewarded; those who hesitated or overcropped produced dilute wines.

• June was very hot and dry; July was hot and even drier, prompting drought stress in younger vineyards
• August turned cool and wet, keeping acidity high and slowing maturity after the scorching July
• Late September rain triggered widespread botrytis, forcing an early, frenzied harvest across Mosel, Nahe, and Rheingau
• Warm temperatures returned through October, continuing the concentration of botrytis-affected grapes on the vine

The Mosel was the vintage's headline act, particularly for noble sweet styles. The rapid and widespread botrytis that arrived in late September transformed many vineyards into sources of Auslese, Beerenauslese, and TBA material rather than the lighter Kabinett and Spätlese wines the region typically prizes. Cooler parts of the Saar were somewhat less affected by botrytis, giving producers there more flexibility at lower Prädikat levels. In the Pfalz and Rheingau, estates also reported excellent quality for those who harvested selectively, with VDP-Palatinate chairman Hansjoerg Rebholz declaring the vintage capable of magnificent results. Across all regions, the key variable was timing and rigor of selection; the best wines came from late pickers who sorted carefully.

• Mosel: exceptional noble sweet wines from Auslese to TBA; Kabinett and Spätlese production severely limited by botrytis and sheer ripeness levels
• Saar: cooler sites less affected by botrytis, producing more structured wines at lighter Prädikat levels than the Middle Mosel
• Rheingau: Robert Weil and others harvested QbA and Kabinett before late September rains, then picked premium sweet categories after a few days of dry weather
• Ahr: the vintage was celebrated especially for Spätburgunder, described as very good and even better than 2003

The 2006 vintage produced some of the most celebrated noble sweet Rieslings in decades. Mosel Fine Wines re-tasted over 150 wines from estates including Geltz-Zilliken, Fritz Haag, Schloss Lieser, Egon Müller and Le Gallais, Joh. Jos. Prüm, Willi Schaefer, and von Schubert, declaring it a resounding success. At Dr. Loosen, Ernst Loosen assembled his largest-ever harvest crew of 50 pickers and completed the harvest in under four weeks, roughly half the normal duration, securing exceptional Auslese and higher-Prädikat wines from sites like the Ürziger Würzgarten and Graacher Himmelreich. At Joh. Jos. Prüm, the estate harvested essentially nothing other than Auslese. Egon Müller lists 2006 among the finest years for his Scharzhofberger Auslese Goldkapsel.

• Joh. Jos. Prüm: produced almost entirely Auslese and higher categories; Wehlener Sonnenuhr wines are among the vintage's most sought-after
• Dr. Loosen: Graacher Himmelreich Beerenauslese achieved 95 points from Wine Enthusiast; range spans single-vineyard Auslese through TBA
• Egon Müller: 2006 ranked among the best years for Scharzhofberger Auslese Goldkapsel alongside 2005, 2010, 1999, and 1994
• Fritz Haag, Geltz-Zilliken, and Willi Schaefer: all singled out in the Mosel Fine Wines 10-years-after retrospective as outstanding performers

The noble sweet wines of 2006 are built for the very long term. Mosel Fine Wines noted after a decade of aging that the 2005 and 2006 duo had already achieved epic stature but that neither vintage was fully ready. The combination of very high sugar readings, exceptional acidity levels comparable to 2001, and the Mosel's naturally low alcohol framework gives Auslese, BA, and TBA wines from this year decades of aging potential. Kabinett and Spätlese production was extremely limited and much of it was, in effect, declassified Auslese in terms of sugar weight; these wines are at or near their peak now. Collectors with Auslese Goldkapsel, BA, or TBA from top estates should continue to hold.

• Kabinett and Spätlese (where produced): largely at peak drinking now, with the best examples still showing vibrancy through 2028
• Auslese and Auslese Goldkapsel from top Mosel estates: entering a broader drinking window now but will continue to develop through 2035 and beyond
• Beerenauslese and TBA: long-term cellaring wines, potentially improving for 40 or more years from harvest; not yet at peak
• The 2005 and 2006 duo is considered of comparable epic stature for Mosel dessert wines; either vintage rewards patience in the cellar

Unlike the restrained, delicate style of classic cool-vintage Mosel Riesling, the 2006s are rich, concentrated, and botrytis-driven across the premium tier. At their finest, the sweet wines display aromas of tropical fruits including pineapple and coconut rather than the simpler apricot and honey of more typical botrytis years, paired with marzipan complexity. The acidity framework, though abundant, is integrated rather than sharp, providing structure without austerity. The vintage rewarded patience and meticulous selection; wines made by producers who harvested too early or without careful sorting showed dilution or unwanted rot characters. This is not a vintage celebrated for dry Riesling or classic Kabinett elegance; its greatness lies squarely in its noble sweet tier.

• Aroma: tropical fruits (pineapple, coconut, mango), honey, marzipan, dried apricot, and saffron in the richest sweet styles
• Palate: high residual sugar balanced by exceptional acidity; wines are never cloying due to structured acid backbone comparable to 2001
• Style split: noble sweet categories (Auslese through TBA) excel; Kabinett and Spätlese production was very limited and often reflects declassified Auslese ripeness
• Aging trajectory: slow development with extraordinary longevity in the sweet categories; top TBA wines may approach near-indefinite cellaring potential

The 2000s were a pivotal decade for German Riesling, producing a string of high-quality harvests punctuated by extremes. The 2003 heatwave vintage produced powerful but often low-acid wines; 2005 is widely considered a great balanced year; and 2006 is the decade's benchmark for noble sweet styles. Joel Payne's retrospective assessment put it plainly: 2006 will be remembered for its wealth of noble late-harvest Rieslings. The vintage is paired almost inseparably with 2005 in critical assessments, with Mosel Fine Wines describing the two as a duo of epic stature for Mosel dessert wines. Unlike 2005, however, 2006's greatness was concentrated in the sweet tier; dry and off-dry wines were secondary achievements due to the pervasive botrytis.

• 2003: extreme heat vintage, often low acidity; 2006 surpassed it in both sugar and acidity at the BA and TBA level
• 2005: celebrated balanced vintage; 2005 and 2006 are described together as an epic duo for Mosel dessert wine
• 2007: followed as a very different vintage, favoring dry styles; far fewer botrytized wines produced than in 2006
• 2001: the acidity benchmark of the decade; producers noted 2006 acidity levels as comparable to 2001
