Koenig produces wines from Alsace, the northeastern French region celebrated for aromatic white varieties and mineral-driven expressions. The winery focuses on three classic Alsatian grapes: Pinot Gris, Riesling, and Gewürztraminer. Each brings distinct character to the cellar—Pinot Gris offers body and subtle fruit complexity, Riesling delivers precision and acidity, while Gewürztraminer contributes floral intensity and spice. Wine Enthusiast and Wine Spectator have rated Koenig's Pinot Gris and Riesling at the upper end of their ranges, reflecting the technical demands of these varieties in Alsace's continental climate. The winery's Gewürztraminer rounds out a portfolio rooted in terroir-driven winemaking, where cool nights and limestone-rich soils shape the final character of each vintage.
