James Suckling, a respected voice in the wine community, awarded this wine an excellent score of 94 points. His review, published on jamessuckling.com on March 5, 2021, describes the wine as having "beautifully pure cherry, berry, black-olive and lightly toasted coffee-bean aromas." He notes that these aromas transition seamlessly to a "full body with a lovely center palate and purity of fruit." Suckling praises the wine for its "lots of fine tannins" and commends its "balanced and poised" nature, highlighting the "wonderful depth" of the wine.

An interesting point Suckling makes is regarding the production volume of this vintage. He points out that it has a "tiny production – only 20% of the normal production," which suggests that this wine could be quite exclusive. He also mentions that the wine "needs two or three years to come around," recommending that it be tried after 2022.

Overall, the 2018 Marsau Bordeaux Blend is characterized by its rich and complex flavor profile, underpinned by a robust structure of fine tannins. The organic growing practices and limited production volume add an element of exclusivity and care to this vintage. James Suckling's high praise and detailed description suggest that wine enthusiasts should look forward to enjoying this Bordeaux Blend in the coming years.
