Spreitzer produces Riesling from the Rheingau, Germany's premier region for the variety. The winery's portfolio centers on dry and sweet expressions from classified vineyard sites. Oestricher Trocken, a dry Riesling, and Oestricher Doosberg Riesling Auslese, a naturally sweet wine, both achieve 94-point averages from prestige critics including Wine Advocate, Wine Spectator, Wine Enthusiast, Falstaff, and Decanter. The Hallgartener Würzgarten Riesling Eiswein VDP.Erste Lage—a rare ice wine from a first-growth vineyard—scores 93.7 across the same panel. These wines reflect the Rheingau's cool-climate precision: mineral acidity, stone-fruit character, and the ability to balance ripeness with freshness across styles from bone-dry to lusciously sweet.
