Exceptional and profound, this 2017 Grosses Gewächs Reserve from Dr. Loosen's Erdener Prälat 'Alte Reben' vineyard is a masterpiece of aged Riesling, showcasing an intricate tapestry of ripe apricot, candied citrus peel, and a distinct slate minerality. Sourced from ancient, ungrafted vines and aged meticulously, it delivers remarkable concentration, a vibrant acidity that cuts through its richness, and an incredibly long, complex finish that will evolve for decades.
