Alfred Graf produces wine in Rheinhessen, Germany's largest wine region by volume. The winery's Erdener Treppchen Vineyard Riesling Spätlese, made from Riesling grapes, represents its work in the steep, slate-rich vineyards of the Mosel valley's Eifel region. Riesling from this terroir characteristically expresses mineral precision and stone-fruit complexity, with the Spätlese designation indicating late-harvest fruit that brings riper phenolics and residual sweetness. Wine Enthusiast and Wine Spectator have both assessed the winery's offerings. The Erdener Treppchen bottling reflects the traditional German approach to Riesling: balancing natural acidity with subtle sweetness to create wines of structure and aging potential.
