Decanter awarded this wine an excellent score of 96 points, describing it as "sweet, baked red fruits with rose and pink floral aromas on the nose alongside touches of clove, toast and cinnamon." The review highlights its smooth, soft texture and rich yet elegant profile, with a supple core of strawberry, cherry, and raspberry flavors. Decanter notes its "mineral, iron, salty tang" that lingers on the tongue, with tobacco and dried spices adding contrast to the ripe, herbal-edged fruit. They conclude, "A really delicious, mouthwatering compelling glass of wine. Succulent and oh so lifted and juicy."

James Suckling also highly praised the wine, giving it 95 points. He described it as "spicy and vibrant with a mix of red and dark berries with dried citrus peel, chili pepper, and spicy herbs." He noted its full body with layers of polished tannins and a chalky, powdery texture, mentioning that it shows "depth and concentration" with "juicy acidity coming through." Suckling suggests that the wine will be even better from 2026 onwards.

Vinous scored the wine 94 points, with Antonio Galloni stating that the 2021 Concerto di Fonterutoli is "plush and resonant to the core."

Robert Parker's Wine Advocate also gave the wine 95 points. Monica Larner described it as a "thickly extracted wine that carries its fruit weight over a long and velvety mouthfeel."
