Peter Lauer’s legendary Ayler Kupp vineyard, with its jaw-dropping 70-degree incline on the Saar’s slate soils, produces some of Germany’s most distinctive Rieslings. Fifth-generation winemaker Florian Lauer vinifies individual parcels separatelythis Fass 3 expression offers a lightly off-dry (Feinherb) profile that showcases the Ayler’s characteristic slate minerality and spontaneous fermentation character. The wine ferments wild, without cultured yeasts, drawing intensity from the vineyard’s own microbial ecosystem. Serious German Riesling in time-honored tradition.
