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

In the glass, this rare Auction 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 uncompromising Extra Brut dosage. The creamy, pinpoint mousse lends additional structure to the palate, culminating in a long, pure finish shaped by fruit, minerality, and invigorating freshness.

Striking a magnificent balance between freshness, fruit, and mineral tension, the Kupfergrube Riesling Sekt Extra Brut Versteigerungswein 2018 shines at celebratory occasions and alongside refined hors d'oeuvres or shellfish, and will continue to gain depth, elegance, and complexity with further bottle age.
