Far Mountain
Fission Cabernet Sauvignon 2023
Sonoma Valley
Fission is a dry-farmed, pure mountain wine, showcasing dark, intense fruit shaped by the cool elevation of the Alta Vista vineyard. With deep texture and sappy concentration from the old, 50-year-old vines, it builds into powerful tannins that remain refined, almost cloaked by the seductive fruit and gently evolving structure. The unique volcanic soils impart textural and mineral complexity, contributing to the wine’s earthy and savory tones. The terraced vineyard, nestled in the Mayacamas mountains, gives Fission a precise, saline minerality and remarkable depth that define its greatness.
VINTAGE
The 2023 Moon Mountain vintage stands out due to consistent, mild weather and above-average yields, resulting in wines of exceptional density, concentration, and structure. The region's low-yielding vines, producing at half the level of Sonoma County’s average, benefit from extended hang time due to later bud break and harvest. The challenging soils and elevations stress the vines, producing fruit with intense flavors and a high skin-to-fruit ratio. The result is wines with powerful tannins, balanced acidity, and impressive aging potential.

Reviews

James Suckling - December 10, 2025 "Aromas of spices and dark fruit with a real mountainous yet refined feel. The palate has such purity and precise focus, with a densely packed fruit and dried flower profile and ferric, graphite and herbal undertones. What a wonderfully crafted cabernet sauvignon."

Amotus Cabernet Sauvignon
Sonoma Valley, Sonoma County, California
Fission is a wine of texture, with the intensity and concentration we associate with old vines. It builds into powerful tannins that remain refined, almost cloaked by the seductiveness of the fruit and the gently building structure. The name Fission was ultimately chosen to reference the textural and mineral characteristics that the unique volcanic soil brings to this wine.
Bresa Chardonnay
Sonoma Valley, Sonoma County, California
Bresa Chardonnay is a wine of substance, grown from the oldest block of Bald Mountain Vineyard, planted in 1972 with Wente clones on fractured volcanic rock. This single-parcel, dry-farmed site yields just one barrel, producing a wine of depth, tension, and dazzling clarity. Far Mountain is rooted in the belief that the most profound wines come from remote mountain sites in Sonoma. Their growers have taken decades of risk, and the winery channels that drama into wines of energy, texture, and endless fascination.
Montecillo Cabernet Sauvignon
Moon Mountain, Sonoma County, California
The Montecillo vineyard is one of California’s most historic sites, first planted in 1860. This Cabernet Sauvignon reflects the vineyard’s high elevation, volcanic soils, dry-farming, organic viticulture, and pioneering spirit. Refined and complex, it honors over a century of resilience and innovation at Montecillo, embodying the enduring legacy of California winemaking.
Myrna Chardonnay
Sonoma Valley, Sonoma County, California
Myrna combines Bald Mountain’s surprisingly delicate floral notes that move quickly to ripe yellow and more exotic fruits with salty, lime and green fruit-inflected notes from Thornton Vineyard. The sappy texture of the wine makes its presence felt, and this grows into a more defined and powerful structure with layers of spice persisting through the finish.
