The 2013 Gemstone Proprietary Red Wine is a robust and complex offering from California's renowned Napa region. Crafted from a blend of Bordeaux varietals, this wine stands out for its concentration and depth, as highlighted in multiple professional reviews.

Robert Parker's Wine Advocate awarded it an impressive score of 96, describing the wine as "profound" and rich with layers of graphite, blackberries, and blueberries. The review emphasizes the wine's complexity and the lasting impression it leaves, with a finish that extends close to 60 seconds. Parker suggests that this wine can be savored over a span of 15 to 20 years, indicating its potential for aging.

Kevin Johnson from JJ Buckley offers a similarly glowing review, scoring the wine at 94. He notes its "very dark purple core" and the concentrated aromas of dark chocolate, tilled earth, and cassis. The palate mirrors these aromas, adding a touch of evergreen and an undercurrent of earthiness. Johnson praises its balance, achieved through bright acidity and fine-grained tannins, and appreciates the mineral-driven, slightly chalky finish. He advises that the wine will be at its best between 2018 and 2035.

Overall, the 2013 Gemstone Proprietary Red Wine is celebrated for its rich complexity and depth. Its robust structure and the potential for long-term aging make it a noteworthy choice for enthusiasts of Napa Valley reds. Both reviews highlight its layered flavors and the balance achieved by its composition, making it a compelling option for those seeking a wine with both immediate appeal and enduring potential.
