Researchers have demonstrated the ability to identify the complex chemical signatures emitted from grapes and wine to predict quality risks in wine production faster and more affordably than conventional methods.

Moët Hennessy, the wine and spirits division of LVMH, Analog Devices, Inc. (ADI), a global semiconductor leader, and University of California, Davis, a world-renowned leading research university, today announced a groundbreaking joint effort to deploy a new generation of technology aimed at enhancing wine quality and supporting the long-term vitality of vineyards.

The collaboration builds on a breakthrough technology that has its roots in early research at the Massachusetts Institute of Technology (MIT). Today, ADI continues to advance this technology platform for analyzing chemical signatures across a broad range of applications and, together with teams from Moët Hennessy and UC Davis, is exploring its use in viticulture and winemaking. The joint effort aims to detect and interpret volatile chemical signatures emitted by grapevines, juice, and wine, giving viticulture and winemaking teams much earlier insights into biological processes and potential quality risks.

A world first demonstration: predicting Fresh Mushroom Aroma before it develops

The collaboration’s first major achievement addresses one of the wine industry’s most complex quality challenges: Fresh Mushroom Aroma (FMA). Researchers at Moët Hennessy’s Robert-Jean de Vogüé Research Center have built a unique library of samples and associated data to train machine learning algorithms to recognize the chemical signatures associated with this quality risk.

For the first time, the technology successfully identified samples presenting an elevated risk of developing FMA at an early stage, well before the defect would traditionally be detected. This breakthrough creates entirely new possibilities for proactive quality management, enabling earlier interventions and fundamentally changing how quality risks may be monitored throughout the winemaking process.

Powered by ADI's sensing and machine learning platform, the system analyzes a broad spectrum of chemical information and uses AI to identify which signals matter most, revealing patterns that may otherwise go undetected. Rather than looking only for predefined conditions, the platform continuously learns from complex chemical data, enabling a deeper understanding of biological activity and emerging quality risks.

A technology platform with multiple future applications

Beyond FMA, the organizations view this technology as a scalable platform for living systems analysis, with potential applications wherever biological processes generate meaningful chemical signatures that can be measured, interpreted and acted upon. Additional applications being researched include early detection of vine diseases, soil assessment, and identification of other defects, especially those linked to climate change and related events (e.g., wildfires).

The goal is to support, not replace, human expertise by equipping researchers, viticulturists, and winemakers with decision-support tools for earlier detection and deeper insights. The technology is designed to augment the expertise of growers and winemakers, providing additional information and context while preserving the craftsmanship, experience, and judgment that remain central to exceptional winemaking.

An international collaboration uniting technology, AI and life sciences

The effort combines complementary expertise from:

• Moët Hennessy, the world leader in premium and super-premium wines and spirits
• ADI, a global semiconductor leader that bridges the physical and digital worlds to enable breakthroughs at the Intelligent Edge; ADI Health Solutions, ADI’s business unit focused on developing AI-driven solutions that contribute to the health of people and the planet
• UC Davis, internationally recognized as a global leader in viticulture and enology

Together, the organizations aim to unlock new capabilities for observing, understanding and interpreting the complex grape and wine matrix in support of quality and resilience across the wine industry. Beyond this initial collaboration, ADI intends to make this technology broadly available for future industrial applications, while Moët Hennessy and UC Davis are exploring how shared reference libraries could benefit the wider grape and wine industry.

Manuel Reman, member of the Moët Hennessy Executive Committee, overseeing R&D, and Member of the Comité Champagne: "This breakthrough marks the beginning of a new chapter for viticulture and winemaking. We can rapidly detect and interpret the chemical language of grapes and wine to anticipate quality risks before they become visible. Beyond a technological achievement, this opens an entirely new way of understanding and working, one that will help us produce exceptional wines while building greater resilience for the future."

Max Shulaker, Chief of ADI's Health Solutions Business Unit: "This collaboration unites world-class expertise in cutting-edge AI-enabled sensing systems and viticulture to accomplish something previously impossible: reading the chemical language that living systems emit themselves. By recognizing these signatures before conventional methods can, this technology can help winemakers shift from reacting to quality risks to anticipating them. Our first breakthrough addresses Fresh Mushroom Aroma, but it marks the beginning of a much broader platform for understanding living systems, one that can improve quality and resilience in ways that are just now being explored and unlocked."

Ben Montpetit, Ph.D, UC Davis: "In the face of major global challenges, the continued advancement and resilience of the grape and wine sectors will depend on two things: better knowledge and people equipped to put that knowledge into practice. What is especially powerful about this collaboration is that we are advancing both. We are developing technology that can give viticulturists and winemakers the right information at the right time to make informed decisions, while also training the next generation of experts who will know how to interpret and act on those insights."
