2015

When Christian Moueix — steward of Château Pétrus — crushed his first Napa vintage in 1983, he made a deliberate choice that ran against the valley's entire trajectory: no irrigation, ever. That single decision, transplanted from his family's Pomerol operations, defines every bottle of Dominus produced since.

The fruit comes exclusively from Napanook Vineyard, a 108-acre planted estate on an alluvial fan spreading from the Mayacamas foothills in Yountville AVA. Upper blocks sit on the coolest, uppermost volcanic gravelly clay-loam, where natural drainage and dry-farming force root systems deep into the subsoil, producing small berries with dense phenolic concentration. Afternoon breezes off San Pablo Bay extend hang time and preserve structural acidity.

Vinification proceeds lot-by-lot by block, with hand-sorting complemented by optical berry-sorting, gentle pump-overs, and a low-pressure vertical press for delicate skin extraction. The wine ages in 100% French oak barriques for approximately 15–18 months, with roughly one-third to 40% new wood — restrained by Napa standards — before barrel-to-barrel racking with no fining agents cited by the producer.

The 2015 vintage is not individually documented in producer release notes, but the house's structural signature — graphite spine, dark currant, tobacco, iron-edged minerality — is anchored by the same dry-farmed Napanook terroir that gives Dominus its 30-year-plus aging trajectory, setting it apart from virtually every other Napa Cabernet of its price tier.
