Food pairing

Decant and pair with dry-aged beef, roast lamb, wild game, or porcini risotto; mature cheeses like Comté or aged cheddar complement its depth.

Serving

Decant

Yes (1-2 hours) — The wine has high tannins and is still relatively young at 7 years, which can benefit from aeration to soften the tannins and enhance the overall flavor profile.

Sustainability

Sustainability score: 8/10

Extreme focus on native ecosystem preservation; significant portions of estate left wild; erosion control; dry-farming largely practiced; solar energy for facility; recycled/reclaimed water for vineyards and landscaping; low-impact packaging (recycled glass and eco-friendly materials); commitment to carbon reduction and waste minimization

Promontory, under the Harlan family, is known for environmental stewardship, habitat conservation, and responsible resource use. While not organic or biodynamic certified, the estate’s extensive green practices, combined with Napa Green certification, position it as a sustainability leader among luxury Napa estates. Energy and water conservation efforts are advanced, but international shipping and packaging weight increase carbon impact for non-U.S. buyers.
