High on the slopes above Epfig, Fronholz is one of Ostertag’s most distinctive Riesling sites, shaped by its rocky soils and naturally vivid acidity. The wines are stony and intensely expressive, with a sharp mineral edge balanced by layered fruit and texture. Farmed biodynamically and handled with great precision, it captures the kind of tension and structure that makes Alsace Riesling so compelling.
