Quick Facts: ABV: ~14.9%  |  Origin: Sonoma County, California  |  Vintage: 2017  |  Producer: Hidden Ridge Vineyard

Production & Heritage

Hidden Ridge Vineyard sits at elevations between 1,200 and 1,700 feet above sea level in the Sonoma County foothills of the Mayacamas Mountains. The vineyard's steep 55-percent grade terrain — the namesake of this bottling — forces vine roots deep into volcanic basalt and sandy loam soils, naturally limiting yields and intensifying fruit concentration. Winemakers Timothy Milos and Marco DiGiulio oversee production that relies heavily on hand labor; the extreme pitch of the slopes makes machine harvesting impossible, so fruit is picked entirely by hand and selected by taste rather than chemistry alone. These conditions produce small, thick-skinned berries with pronounced mineral character and structure that set the wine apart from valley-floor Cabernets.

Tasting Notes

Aroma: The nose opens with dense blackcurrant and ripe blackberry, followed by layers of toasted spice and licorice. Deeper in the glass, graphite and crushed stone-like minerality emerge, reflecting the volcanic soils of the vineyard.

Taste: The entry is full and concentrated, with dark berry fruit immediately asserting itself on the palate. At mid-palate, the wine builds with substantial tannin structure and notes of espresso, dark cocoa, and dried herbs. The peak reveals a core of blue-black fruit intertwined with savory graphite and a persistent mineral thread.

Finish: Long and gripping, with fine-grained tannins that taper slowly into echoes of blackberry, toasted oak, and wet stone. The finish sustains its mineral edge for well over a minute, rewarding patience.

How to Serve Hidden Ridge 55% Slope

This is a wine built for careful attention. Decant for at least 45 to 60 minutes before serving at 60–65°F to allow the tightly wound tannins to open and the aromatic complexity to fully express itself. A large-bowled Bordeaux glass concentrates the graphite and dark fruit aromatics effectively. While the 2017 drinks well now with decanting, the wine's tannic backbone and acidity suggest it will reward cellaring through 2030 and beyond. Serving it slightly below room temperature preserves freshness and keeps the alcohol from dominating the palate.

• Pairing with a special steak dinner or holiday prime rib

Why Hidden Ridge 55% Slope?

The defining fact about this wine is its origin: a 55-percent grade vineyard that cannot be farmed by machine and produces intensely concentrated fruit from vines stressed by steep volcanic terrain. The 2017 vintage captured that site at its best, earning 97 points from Robert Parker's The Wine Advocate — a score that places it in the top tier of California Cabernet in any given year. Winemakers Timothy Milos and Marco DiGiulio harvest by taste rather than by numbers, an approach that prioritizes physiological ripeness and flavor development over formulaic winemaking. For collectors and serious Cabernet drinkers looking beyond the most familiar Napa Valley names, this remains one of the most distinctive mountain-grown expressions California produces.
