2017: 50% Syrah, 22% Grenache, 14% Graciano, 8% Petite Sirah, 6% Touriga Nacional

97 points, Jeb Dunnuck. "Showing even better from bottle than barrel, it offers a stunning nose of ripe blueberries, black raspberries, ground pepper, and violets. Full-bodied, rounded, and seamless on the palate, it has a beautiful sense of complexity and purity paired with serious depth of fruit and opulence on the palate."

93 points, Wine Advocate. "Medium to deep ruby, it's scented of dried sour cherries, black cherries and currants with nuances of violet, orange peel, black tea leaves, underbrush and warm earth. Medium to full-bodied, it has a good balance of earth and fruit, with a grainy frame and long, layered finish."

2018: 59% Syrah, 14% Grenache, 14% Touriga Nacional, 13% Graciano

98 points, Jed Dunnuck. "A rich, powerful wine based on 59% Syrah, 14% Grenache, 14% Touriga Nacional, and the rest Graciano, brought up mostly in foudre, the 2018 Heart Stone Vineyard's deep purple color is followed by killer notes of red and black currants, peppery herbs, loamy soil, and assorted meaty, spice notes. It has a Rhône-like spicy, meaty, savory character yet packs gorgeous purity of fruit, full-bodied richness, and sweet, polished tannins that are pure Paso Robles. Enjoy this brilliant blend any time over the coming 10-15 years. Along with the 2007, this is the finest example of this cuvée I've tasted."

98 points, Wine Advocate. "The 2018 Heart Stone Vineyard is big and flavorful but tremendously elegant this vintage. A blend of 59% Syrah, 14% Grenache, 14% Touriga Nacional and 13% Graciano, it has a deep, alluring perfume, loaded with purple flowers, licorice, earth, charcuterie and blackberry pie scents. The palate is full- bodied and structured by wonderfully ripe tannins, exploding with spiced dark fruits that expand effortlessly into a very long, lifted finish. It's stunning now but will offer more with time in the cellar.

I’ve been eagerly anticipating the 2018 vintage in Paso Robles, where cooler temperatures resulted in some unusually elegant, lifted wines. The 2018s from Saxum did not disappoint—these latest releases offer incredible concentration of flavor with surprising elegance and freshness. While they took some time in bottle to unwind, I’m pleased with how they have blossomed over time. These layered, nuanced wines have the intense flavor, ripe tannins and freshness for long-term cellaring, and while they’re stunning now, they’ll offer more a few years down the road. Cheers!"
