"The 2019 Siepi continues a trend toward greater finesse and nuance in this wine. Crème de cassis, lavender, spice, licorice and plum meld together effortlessly in the glass. Dense and layered, with striking detail, the 2019 is so impressive. The flavors are bright, bold and punchy. An exceptionally beautiful and riveting wine, the 2019 is rich and concentrated, but not at all heavy. What a total knock-out."

"This is a really racy and fine Siepi with currant, black-cherry and dark-chocolate character. It’s medium-to full-bodied with very long, intense tannins that are linear and fine-textured. Really builds on the palate. Super structure. Finesse with power."

"In 2019, a 'classic' good quality vintage in much of Tuscany, the vines experienced very large temperature differences between day and night in September, giving perfect ripeness allied to great freshness. This wine combines ripe, fruit-forward and super-floral aromas with a fresh, fleshy and elegant palate showcasing plush black cherry. It seems a bit lighter than the 2020, with more plentiful grainy tannins, making for a focused and harmonious Siepi."

"Now on the market, the Mazzei 2019 Siepi is a special achievement and a delight to taste at the exciting conclusion of this historic retrospective spanning 26 vintages. This edition of Marchesi Mazzei's celebrated blend of Merlot and Sangiovese benefited from ideal growing conditions, with warm days and cool nights throughout the summer season. The clusters were healthy and full. The fruit is crisp and fresh, and the tannins serve to softly support the wine's generous texture and fiber. The 2019 vintage also achieves balance with a pretty assembly of dark fruit, mineral and spice aromas. Production is 35,000 bottles."
"After a subtle nose, this is generous and fruit-driven on the palate, with black cherry and delicious minerality giving that petrichor sort of aroma. Very tannic fur on the palate, finishing with persistent savoury, granitic notes and a touch of beefiness too. 18+/20 points. (RH)"
