Domaine Mersiol produces wines from Alsace, the northeastern French region celebrated for aromatic whites and elegant reds. The winery's portfolio centers on three flagship expressions: a Vendanges Tardives Pinot Gris, a Pinot Noir, and a Riesling Alsace Grand Cru from the Frankstein vineyard. The late-harvest Pinot Gris showcases the region's capacity for concentrated, sweet wines built on the grape's stone-fruit character and subtle spice. The Pinot Noir reflects Alsace's cooler continental climate, where the variety achieves silky texture and red-cherry definition. The Frankstein Grand Cru Riesling taps into one of Alsace's most prestigious terroirs, where the variety's mineral precision and aromatic intensity find full expression. Wine Enthusiast and Wine Spectator have rated the winery's releases.
