Robert Parker's Wine Advocate, represented by reviewer WK, also rated the wine 93 points. The review commended the wine's aromas of "cassis, plums, vanilla pod and orange rind," and described it as a "medium to full-bodied, lively and concentrated wine" with "admirable depth of fruit, vibrant acidity, and powdery tannin." WK concluded that this wine "will be long-lived."

In summary, the 2020 Louis Jadot Gevrey Chambertin 1er Cru Lavaux St Jacques is a robust and complex Pinot Noir, characterized by its deep fruit flavors, vibrant acidity, and well-structured tannins.
