Peter Jakob Kühn – St. Nikolaus VDP Grosses Gewächs Dry Riesling 2006 MAGNUM 1500ml

🏰 Introduction and the Winery

The Peter Jakob Kühn Winery is one of the most renowned and time-honoured estates in the Rheingau. The Kühn family can look back on over 230 years of history in the region and has specialised in Riesling in particular, with the emphasis today being primarily on dry wines.

The winery is run by Peter Bernhard Kühn, a winemaker renowned for his distinctive style and his uncompromising commitment to quality. His vineyards have been organically farmedsince 2004. Fermentation takes place using wild, natural yeasts – a method that has as many supporters as it does critics. Kühn himself comments on this with a shrug, stating that he makes wines that age well.

🍇 The vineyard: Mittelheimer St. Nikolaus

St. Nikolaus is a VDP.Grosse Lage in the Rheingau, belonging to the municipality of Mittelheim. The plots are situated in the immediate vicinity of the Rhine – just around 150 metres away – and benefit from the Rheingau’s excellent microclimatic conditions.

The vineyard is characterisedby its stony, mineral-rich soils, which lend the Riesling a particular depth and complexity. The vines used for the St. Nikolaus are over 60 years old, which explains the wines’ natural concentration and enormous ageing potential.

🍷 VDP.Grosses Gewächs – The premier class

The designation ‘VDP.Grosses Gewächs’ (GG) is the highest quality classification awarded by the Association of German Prädikat Wine Estates (VDP) for dry wines from the finest sites. A GG Riesling is the equivalent of a Grand Cru from Burgundy and stands for:

• Origin exclusively from a VDP.Grosse Lage

• Hand-harvested with strict selection

• Dry vinification (residual sugar below 9 g/l)

• Extended ageing on the lees for greater complexity and structure

Peter Jakob Kühn’s St. Nikolaus GG is one of the Rheingau’siconic wines.

📅 The 2006 vintage in context

The 2006vintage was changeable in the Rheingau and posed a challenge for the winegrowers. A review by Vinous describes Peter Jakob Kühn’s 2006 wines as a ‘mixed bag’ – some were, surprisingly, better than those of the previous year, others less so.

Despite these challenges , the St. Nikolaus GGappears to be one of the vintage’s most successful wines. The community reviews on CellarTracker are predominantly positive and reveal a wine that still impresses almost two decades after harvest.

🍾 The magnum size (1.5 litres)

This bottle is a magnum – that is , a 1.5-litre bottle. The magnum size is particularly sought-after for top-quality wines, as it offers several advantages:

• Slower maturation: The ratio of wine to oxygen (via the cork) is more favourable in a Magnum, leading to a more elegant, refined ageing process.

• Longer shelf life: Magnum bottles age more slowly and can often be stored for decades longer than the standard 0.75-litre bottle.

• Collectors’ value: Large-format bottles are rarer and particularly sought-after at auctions.

👃 Tasting notes and ratings

The community tastings on CellarTracker paint a predominantly positive picture of the 2006 St. Nikolaus GG:

One contrasting experience reports a bottle that had developed a medicinal odour – an indication that the storage history is crucial at this age.

A professional review of the 2016 vintage of the same wine by Robert Parker scores 96/100 points and describes the wine as “profound, cool, intense, rich, refined, salty-mineral, enormously complex and with lingering mineral bite and tension”. This highlights the enormous potential of the St. Nikolaus vineyard.

💰 Market and auction data

The 2006 St. Nikolaus GG in a magnum bottle is a rarity. The available market data:

The comparatively low hammer price of €40 at the auction in July 2026 reflects the condition of the capsule (damaged) and the level of the wine (‘top shoulder’ – several centimetres below the cork). With such an old wine, these factors are decisive for its market value.

By way of comparison: the standard 0.75-litre bottle of St. Nikolaus GG retails for around €60 to $96 – the magnum should command a significantly higher price due to its rarity.

⏳ Drinking maturity and ageing potential

The 2006 St. Nikolaus GG has reached its peak drinking window and is now at its optimal stage of maturity. If stored correctly (constant temperature, high humidity, stored horizontally), a magnum of this age can certainly continue to be enjoyedfor a further 5–10 years.

However, cautionis advisedwith bottles of this age :

• There isa realrisk of cork taint or maderisation (excessive oxidation).

• The level of the wine in thebottle is a key indicator of the quality of the storage conditions.

• Ideally, a tasting should take placein a small, experienced group – with due respect for this almost 20-year-old testament to its era.
