Wild clay from old vineyard soil becomes tasting cups Taste the terroir—in the wine and in the earth Viola Beuscher and GLOW GLOW have joined forces in a quietly shared passion: soil. It’s the same ground that gives Viola the wild clay for her ceramics and nourishes the Baumberger family’s vines. For this collection, we gently gathered clay from a former vineyard and shaped it into tasting cups and carafes. In this way, you can discover the wine’s character—shaped by its terroir—right where it began. Show more. Show less.
