The Kupfergrube Riesling Sekt Extra Brut Versteigerungswein 2018 in Magnum hails from the historic Kupfergrube monopole, one of Germany's most celebrated Riesling vineyards, renowned for its deep, mineral-rich volcanic soils and commanding exposition. Combined with cool nights and an extended ripening season, this singular Nahe terroir yields grapes of crystalline fruit, intense aromatics, and razor-sharp acid structure.

In the glass, the Sekt gleams a delicate straw yellow with a lively, ultra-fine perlage. On the nose, a precise bouquet unfolds with green apples, lime zest, and white peaches, accompanied by floral hints reminiscent of acacia blossom and a seductive mineral depth. With aeration, delicate nuances of lemon peel and white flowers step to the fore, underpinned by a cool, savory note that lends tension and complexity.

On the palate, the Extra Brut is aristocratic and focused. Crisp, crystalline acidity gives the Sekt vibrant energy and carries its finely etched fruit aromatics. Yellow orchard fruits, citrus, and stony minerality unite in a harmonious whole, given chiseled precision by its Extra Brut dosage. The creamy, pinpoint mousse lends additional structure to the mouthfeel, culminating in a long, pure finish shaped by fruit, minerality, and invigorating freshness.

Displaying a magnificent balance between freshness, fruit, and mineral tension, the Kupfergrube Riesling Sekt Extra Brut Versteigerungswein 2018 in Magnum is ideal for celebratory occasions or paired with seafood and refined starters. With further maturation in magnum format, this rare auction bottling will gain even greater depth, elegance, and complexity over the years to come.
