Bestheim produces Riesling and Gewürztraminer from Alsace, the northeastern French region renowned for aromatic white wines of precision and minerality. The winery's Exception Riesling—a wine rated 93 by prestige critics including Wine Enthusiast, Wine Spectator, Falstaff, and Decanter—demonstrates the region's capacity for complexity and depth. The Alsace Grand Cru Schlossberg Riesling, rated 92, draws from one of Alsace's most distinguished vineyard sites, where slate-rich soils impart distinctive mineral character. The Lieu-Dit Roemerberg Réserve Gewürztraminer, also rated 92, showcases the spiced, floral intensity Gewürztraminer achieves in this terroir. Riesling and Gewürztraminer thrive in Alsace's continental climate, where cool nights preserve acidity and aromatic compounds. Bestheim's focus on these classic varieties reflects the region's viticultural identity.
