The 2021 Siran Bordeaux Blend is a red wine from the Margaux sub-region of Bordeaux, France. This wine is produced by Siran and is sealed with a cork closure. It has garnered positive reviews from multiple professional wine critics, consistently scoring 91-92 points.

Jane Anson, writing for janeanson.com on December 6, 2023, describes the 2021 Siran as "one of the highlights of the 2021 vintage in Margaux." Anson notes its lighter frame compared to recent vintages but commends its flavor, grip, and juiciness. She highlights the fresh acidities of the vintage, which manifest as "textured slate minerality" and "bright fruits." This wine's harvest took place from September 23 to October 9, yielding a generous 51 hectoliters per hectare, with 35% of the wine aged in new oak.

Jeff Leve of TheWineCellarInsider.com, in his March 9, 2024 review, also awarded the wine 92 points. He praises its aromatic profile of "black cherries, plums, flowers, and a dollop of cocoa," and describes the palate as "supple, creamy, and fresh" with a "dusty, edged finish." Leve suggests that the wine will be best enjoyed between 2025 and 2040.

James Suckling, in his December 14, 2023 review for jamessuckling.com, also gave the wine 92 points. He notes aromas of "cherry stones, currants, tobacco, and lemon peel," and finds the wine to be "sleek and focused, elegant, with fine-grained tannins, a medium body, and a creamy, linear finish." Suckling recommends trying the wine from 2024 onward.

Neal Martin of Vinous, in his February 22, 2024 review, gives the wine a slightly lower but still respectable score of 91. He describes an "open bouquet with raspberry and blackberry fruit, iodine, and light iris flower scents." Martin notes that the wine is medium-bodied with "pliant tannins" and more black fruit, attributed to the 60% Cabernet Sauvignon in the blend. He also points out that the wine will drink sooner than other vintages but is worth seeking out given its price.

Finally, Decanter's review from April 1, 2022, also scores the wine at 92 points, highlighting "pretty, wild floral notes on the nose alongside fresh raspberry." The review describes the wine as "supple and agile" with "chalky, creamy red fruits and soft, fine, graphite-edged tannins." It praises the wine's "unfussy charm" and "lovely crushed stone salinity on the finish."

Overall, the 2021 Siran Bordeaux Blend is well-regarded for its bright fruit flavors, fresh acidity, and elegant tannins. It is noted for its approachability in the near term while still offering potential for aging.
