Food pairing

Prime dry-aged ribeye, lamb with rosemary, mushroom risotto, aged Gouda, black truffle dishes.

Serving

Decant

Yes (1-2 hours) — The wine has high tannins and is structured, which can benefit from aeration to soften the tannins and enhance the flavors.

Sustainability

Sustainability score: 7/10

Sustainable farming (cover crops, runoff control), water conservation/drip irrigation, solar energy, light-weight bottles, local sourcing for packaging materials where possible.

Stag’s Leap Wine Cellars is a leader in winery sustainability within Napa Valley, certified Napa Green since 2010 for both its vineyards and winery facility. They employ numerous eco-conscious practices—efficient water use, erosion control, biodiversity encouragement, and solar power generation. However, the use of heavier glass bottles for luxury cuvées like Cask 23 and the wine’s international transport contribute to a higher carbon footprint than small-scale, locally consumed wines. No organic or biodynamic certification, but the estate’s broad sustainability culture places it above the industry standard.
