The 2020 Weingut Clemens Busch Marienburg Riesling Grosses Gewachs is a distinguished white wine from the Mosel Saar Ruwer region in Germany, specifically the Middle Mosel's Punderich appellation. Produced by Weingut Clemens Busch, this Riesling showcases the classic attributes of the varietal with a modern twist, all encapsulated within a 12% alcohol content and sealed with a natural cork.

James Suckling, renowned for his insightful wine reviews, awarded this Riesling a score of 94. He highlights its "complex fresh-herb character," complemented by notes of white fruit and lemon curd. Suckling notes the wine's "discreet succulence" and "lemony freshness," which contribute to a balanced, medium-bodied palate. He describes the finish as having a "serious structure" that is "slightly austere" and "savory." This wine is crafted from biodynamically grown grapes with Respekt certification, indicating a commitment to sustainable and ethical winemaking practices.

Robert Parker's Wine Advocate, with Stephan Reinhardt as the reviewer, scored this Riesling even higher at 95 points. Reinhardt praises the wine's "pure and fresh" nose, which perfectly represents its terroir despite a "sur lie layer." The palate is described as "very elegant and refined," with a "lush, well-balanced" texture that has become creamy over time. The finish is "long, saline and finely tannic," suggesting this Riesling's aging potential. Reinhardt recommends cellaring the wine for an additional 3 to 4 years to allow it to regain its purity.

Both reviewers agree on the wine's elegance and balance, with Reinhardt calling attention to its refined texture and Suckling noting its serious structure. This 2020 Riesling from Clemens Busch is a testament to the quality and character of Mosel wines, offering complexity and freshness that will appeal to Riesling enthusiasts.
