Opus One earns the elite Butterfly Mark, showcasing its leadership in sustainable luxury.
Opus One, the iconic Napa Valley estate has secured one of the most prestigious accolades in the luxury sector, the Butterfly Mark from Positive Luxury.
This certification, specifically crafted for ultra-premium brands, recognises industry leaders committed to sustainability at the highest levels. Launched in 2011 by London-based sustainability consultancy Positive Luxury, the Butterfly Mark sets the benchmark for environmental and social responsibility across the luxury landscape from fashion houses to fine wine producers.
According to Positive Luxury, the initiative was designed with one clear mission: to ensure that luxury leads the charge when it comes to sustainable business practices. Their model tailors sustainability criteria to the unique challenges and standards faced by high-end companies, and annual fees for participation reflect that bespoke approach, stretching to £50,000 for businesses generating turnover in excess of £100 million.
Other Butterfly Mark holders include globally recognised names like Monica Vinader, Erdem, Coco de Mer, and the Marbella Club Hotel. With this latest certification, Opus One becomes part of a highly select group redefining what modern luxury should stand for.
Securing the Butterfly Mark is no small feat. Unlike the B-Corp model which renews every three years, brands under the Butterfly programme are re-evaluated every two. The process typically takes up to 12 months and involves an in-depth assessment across three critical pillars:
To pass, companies must meet a minimum threshold of 50% in each category.
Opus One demonstrated extensive improvements and forward-looking strategies across these areas, guided throughout by a dedicated advisor provided by Positive Luxury. Once certified, the winery also gains access to the Connected Butterfly Mark, a digital tool, often embedded via QR code, that gives customers transparent insights into the company’s performance and progress.
Opus One’s sustainability credentials are just the latest chapter in its already storied legacy. Known for crafting two refined red blends in the Bordeaux tradition, its flagship “Opus One” and its second wine “Overture”, the estate remains one of California’s most collectible fine wines.
Its bottles routinely command thousands on the secondary market. A 100-case collection of the 1979 vintage fetched $165,000 via Sotheby’s China in 2013, while the most eye-watering sale to date came in 2015, when a “Chair’s Lot” secured a staggering $2.4 million at Auction Napa Valley.
In last year’s Liv-ex Power 100 ranking (a list of the most powerful fine wine brands globally) Opus One placed 21st, one of only six Californian names to make the cut. That was a notable drop from its No. 4 position in 2023, with the average trade price per lot reaching £2,770. Market volatility aside, the brand’s recognition on the global stage remains strong.
In a move to bolster its leadership and winemaking continuity, Opus One also announced the appointment of Meghan Zobeck, formerly of Screaming Eagle as its first Director of Winemaking. Michael Silacci, who has served in the lead role for 24 years, will continue overseeing harvest strategy, blending, and operational oversight.
Commenting on the certification, Positive Luxury noted that Opus One’s achievement marks a clear signal of intent: a commitment not just to quality winemaking, but to reshaping the future of luxury itself. As the fine wine world increasingly aligns with sustainability and ethical leadership, Opus One is showing that world-class terroir and responsible business practices can and must go hand in hand.
