Robert Parker's Wine Advocate, represented by Stephan Reinhardt, gave the wine a 96 score. Reinhardt described it as having an "intense, golden-yellow color" and noted that it comes from a very warm but humid year in Styria. He praised its "generously intense but elegant and balanced bouquet" of ripe, dark yellow fruits with fresh lemon aromas, along with saline and caramel nuances. On the palate, the wine is "generous and rich but also refined and saline," with a finish that is "dense, intense and powerful yet structured by helpful fine tannins and the Zieregg's characteristic sustainable salinity and tension." Reinhardt observed that the wine has mild yet fine acidity and clear, juicy fruit. He also mentioned that the wine was picked from older vines, aged on the fine lees for 42 months, and bottled unfiltered, representing the essence of the 2018 vintage in the Zieregg.
