The 2020 Domaine Zind Humbrecht Riesling Clos Hauserer is a notable expression of Alsace Riesling, originating from the Wintzenheim appellation in the Haut Rhin sub-region of France. Produced by Domaine Zind Humbrecht, this wine is crafted from biodynamically grown grapes, showcasing the winery's commitment to sustainable viticulture.

James Suckling awarded this wine an impressive 96 points, highlighting its ability to thrive on clay-rich soils, contrary to the common belief that Riesling performs best on stony grounds. Suckling describes the wine as having "so much citrus and peach," with a "rich and powerful" profile. He praises its "breathtaking succulence," noting the excellent integration of concentration, fine tannins, and bright acidity that contribute to its long and complete finish. He suggests that it can be enjoyed now or held for future drinking.

Robert Parker's Wine Advocate, through reviewer Stephan Reinhardt, also provides a positive review, rating it at 92 points. Reinhardt notes the wine's origins from a "warm setting below the grand cru Hengst," with marly soils overlaying limestone rock. He describes the wine as "very intense but pure and iodine-like on the nose," with a "full-bodied, silky-textured, very elegant" character. The wine is noted for its saline qualities and fine tannins, though Reinhardt mentions it has a "somewhat narrow and caged" profile, with a touch of astringency on the finish. Bottled with 6.6 grams per liter of residual sugar, this Riesling maintains a moderate alcohol level of 13.2%.

Overall, the 2020 Domaine Zind Humbrecht Riesling Clos Hauserer is a rich and powerful wine that exhibits both elegance and complexity, making it a compelling choice for Riesling enthusiasts seeking a distinctive Alsace wine.
