Promontory wines are designed for long-term aging, combining Napa intensity with old-world structure and cool site minerality. 2017 is a classic, ageworthy vintage from a highly selective terroir in the Mayacamas hills, backed by the Harlan pedigree.

Food pairing

Prime-aged beef, wild venison, porcini mushrooms, rich truffled dishes, aged hard cheeses such as Comté or Parmigiano.

Serving

Decant

Yes (1-2 hours) — The wine has firm, high-quality tannins that will benefit from aeration, allowing it to open up and enhance its flavors.

Sustainability

Sustainability score: 7/10

Estate farmed with sustainable methodologies; intensive erosion control, dry farming when possible, significant native flora retention, low chemical input, biodiversity emphasis. Modern energy/water use (gravity-flow, native vegetation buffers, minimal irrigation). Packaging is traditional (heavy bottle, wooden case), which limits environmental gains. Low volume/lot production allows greater stewardship but not industry-leading innovation.

Promontory operates under the Harlan Estate philosophy of long-term ecological stewardship, minimizing chemical interventions and emphasizing natural balance in the vineyard. However, a lack of formal environmental certifications and the use of heavy, non-recyclable packaging dampen its sustainability profile. Though practices are above conventional Napa standards and site-specific stewardship is evident, further improvements (e.g., lighter bottles, renewable energy, formal certifications) would boost sustainability. Its carbon footprint remains elevated compared to locally consumed, lighter-packaged wines.
