Barrel Proof Technologies (“Barrel Proof”), a technology company developing non-invasive sensing and predictive intelligence solutions for barrel-aged and other sealed physical assets, announced the appointment of Jeff Hopmayer to its Board of Directors. 

Hopmayer (pictured) has also acquired an ownership interest in the company, reflecting his long-term conviction in Barrel Proof’s technology, intellectual property, and strategic vision. 

Hopmayer founded Brindiamo Group, one of the world’s largest bulk whiskey trading platforms, and successfully exited the business more than three years ago. During his tenure, Brindiamo facilitated transactions involving hundreds of millions of dollars in barrel inventory while working alongside many of the industry’s leading producers, investors, lenders, warehouses, and brand owners. 

His experience spans the operational, financial, and commercial aspects of barrel-aged assets, making him uniquely positioned to help guide Barrel Proof’s next phase of growth.

Barrel Proof’s technology enables continuous, non-invasive monitoring of sealed physical assets through externally mounted sensors, advanced analytics, and artificial intelligence. The platform is designed to provide greater transparency into inventory condition, helping producers, lenders, insurers, and asset owners make more informed decisions while reducing reliance on manual sampling and estimation.

“Jeff’s decision to join our Board and become an owner is a strong endorsement of both our technology and our long-term vision,” Brian Anderson, Chief Executive Officer of Barrel Proof Technologies, said in a news release. “Few people understand the barrel-aged spirits ecosystem as comprehensively as Jeff. His experience across production, inventory management, financing, and strategic growth will be invaluable as we continue commercializing our platform and expanding into new markets.”

Hopmayer said his decision was driven by the opportunity to help build foundational infrastructure for industries that manage high-value physical assets.

“Following my exit from Brindiamo, I’ve been very selective about where I invest my time, reputation, and capital,” he said. “Barrel Proof is one of those rare opportunities where breakthrough technology, meaningful intellectual property, and a significant market need come together.

“Throughout my career, one of the industry’s greatest challenges has been the reliance on estimates—whether measuring evaporation, proof changes, maturity, collateral value, or risk. I believe Barrel Proof has the opportunity to replace estimation with objective data, creating greater transparency and confidence for producers, lenders, insurers, investors, and ultimately consumers.”

As a member of the Board of Directors, Hopmayer will work closely with the leadership team to support commercial strategy, strategic partnerships, and long-term growth initiatives as the company expands applications for its sensing and predictive intelligence platform.
