2015 Germany & Mosel Riesling Vintage

The 2015 season opened with a smooth, frost-free spring that allowed clean budburst and even flowering across Germany. Warm, dry conditions then persisted through summer, with August bringing genuine drought anxiety as vines reached their most parched state since 1961. A new German heat record of 40.3°C was registered at Kitzingen in Franken. The saving grace came in two waves of precipitation: some rain in early September and more in mid-October, both arriving at cool enough temperatures to prevent rot or mildew. By harvest's end, initial worries about acidity loss largely proved unfounded, and the uniformly healthy, small-berried fruit delivered concentrated, aromatic wines across all styles.

• Frost-free spring enabled clean budburst and even flowering throughout Germany's 13 wine regions
• New national temperature record of 40.3°C set at Kitzingen in Franken during the growing season
• Vineyards were drier by September than at any point since 1961, concentrating sugars and flavors
• Timely September and October rainfall, without rot or mildew, rescued acid balance and freshness

The Mosel excelled in 2015, with its cool microclimate and steep slate slopes moderating the heat to produce fruit-forward, balanced whites with a lovely interplay of sweetness and acidity. Dry Mosel Rieslings were particularly noteworthy, with several estates not typically known for their trocken wines delivering some of their finest results. The Saar sub-region, with its naturally cooler sites, produced wines with more pronounced acidity and mineral precision. The Nahe also performed strongly alongside the Mosel. In the Rheingau, the Robert Weil estate at Kiedrich harvested under ideal conditions, picking all dry Riesling fruit by late October in perfect health. Rheinhessen and the Pfalz, Germany's two largest regions, produced powerful, ripe Grosses Gewächs wines, though quality varied more widely and some examples were felt to be too heavy. Franken showed sophistication and age-worthiness, with a higher proportion of Pradikat-level wines produced.

• Mosel: standout region, with dry Rieslings from the Middle Mosel among the finest in Germany
• Saar and Ruwer: cooler sites retained sharper acidity and mineral definition for long-term aging
• Rheingau (Robert Weil): harvest completed by late October with fine balance between fruit and acidity
• Pfalz and Rheinhessen: powerful, concentrated GGs, though some wines were considered too ripe

Egon Müller's estate on the Scharzhofberger in the Saar produced what many regard as the single greatest wine of the vintage: the 2015 Scharzhof Riesling Auslese Gold Capsule, awarded a perfect 100 points by Robert Parker. Joh. Jos. Prüm, whose Wehlener Sonnenuhr vineyard with its famous 1842 sundial is one of Mosel's most celebrated sites, produced Spätlese and Auslese selections capturing the vintage's ripe stone-fruit generosity. Dr. Loosen, consistently ranked among Germany's top ten estates, demonstrated the Mosel's ability to combine old-vine concentration with elegant acidity. Fritz Haag and Hermann Dohnhoff were among other widely praised names. In the Pfalz, producers such as Dr. Bürklin-Wolf and Keller crafted benchmark dry Grosses Gewächs wines that showcased the vintage's power and freshness at their most balanced.

• Egon Müller Scharzhof Riesling Auslese Gold Capsule 2015: 100 points from Robert Parker
• Joh. Jos. Prüm Wehlener Sonnenuhr: quintessential Mosel ripeness with house-style elegance and aging potential
• Dr. Loosen: old-vine Mosel sites delivering ripe concentration with characteristic mineral freshness
• Dr. Bürklin-Wolf and Keller: powerful, balanced Grosses Gewächs dry Rieslings from the Pfalz

A decade on from the harvest, 2015 Rieslings are broadly in their prime drinking window. Entry-level Spätlese wines show forward, generous fruit profiles ideal for current enjoyment. Auslese and higher Pradikat selections continue to develop complexity, with the best Saar examples and structured Mosel Auslesen capable of evolving further over the next five to ten years. The noble sweet wines, including Beerenauslese and Trockenbeerenauslese, are built for the long haul, with their high sugar and acidity ensuring decades of development. Acidity levels across the vintage, though initially a concern, proved more resilient than feared, underpinning the aging potential of even the fuller-bodied dry styles.

• Spätlese: in or approaching peak drinking, with ripe fruit and generous texture
• Auslese from Saar and structured Mosel sites: prime window now through 2030 and beyond
• Beerenauslese and TBA: long-lived; will develop honey, dried apricot, and caramelized complexity for decades
• Dry GGs from top sites: drinking well now, with the best examples holding through the early 2030s

2015 drew inevitable comparisons to 2003, Germany's previous extreme-heat vintage, but most producers and critics agreed the two vintages should not be equated. Unlike 2003, photosynthesis did not stall in 2015, and better-regulated drought stress meant more balanced, complete wines. The vintage produced outstanding results for both styles: rich noble sweet wines that broke records and surprisingly elegant dry Rieslings. However, for dry Riesling purists, Mosel Fine Wines noted that 2015 lacked the ultimate finesse and precision of cooler benchmark years such as 2004 and 2008, as it was simply too hot for the highest level of refinement. Still, the vintage earned near-universal praise as a great year, sitting comfortably alongside 2009 and 2012 in the modern canon of warm-vintage German Riesling.

• 2015 vs. 2003: more balanced; photosynthesis did not stall as in 2003, giving superior acid structure
• 2015 vs. 2013 and 2014: riper and more generous; those cooler years offer greater mineral precision for dry styles
• For noble sweet wines, 2015 was exceptional with record-breaking quality across multiple regions
• Reflects Germany's broader shift toward warm-vintage success, alongside 2018 and 2019
