Trevor grew up in Sonoma County, at the heart of Northern California’s wine country. Having studied Viticulture and Enology at the University of California, Davis, in 2003 he completed a harvest internship at Russian River Valley-based Sonoma-Cutrer Vineyards, followed by two sparkling wine harvests for Gloria Ferrer in Sonoma’s Carneros District. In late 2005, he joined Moon Mountain Vineyard, a small, well-regarded organic vineyard in Sonoma Valley.

In March of 2010, Trevor joined Provenance Vineyards and Hewitt Vineyard in Napa Valley as assistant winemaker, where the 2010 Hewitt Vineyard Cabernet Sauvignon achieved Wine Spectator’s 2013 #4 Wine of the Year. In early 2015, Trevor became lead winemaker; and in 2017 he was named senior winemaker at Beaulieu Vineyard.

Trevor presides as only the fifth senior winemaker in Beaulieu’s more than one-hundred-year history to craft the winery’s pinnacle bottling—Georges de Latour Private Reserve Cabernet Sauvignon. In 2022, the 2019 vintage of this wine received a perfect 100-point score from JamesSuckling.com – the first 100-point score in the winery’s history. In February 2023, Wine Spectator named the 2019 Beaulieu Vineyard Napa Valley Cabernet Sauvignon its 2022 Wine Value of the Year.

At the ACS: As one of Napa Valley’s founding wineries, Beaulieu Vineyard has kept research and development front of mind ever since first opening its doors back in 1900. Streaming in from the USA, Trevor talks through the history of this iconic property before diving into the notion of “Rutherford Dust,” the unique terroir and how they are battling climate change through modified viticulture and winemaking practices.

Ross obtained a BSc (Hons) in 2016 from the University of Adelaide (UofA) and after working as a technical officer at SA Water, began employment with UofA as a Research Assistant in 2017, working on a project in collaboration with the AWRI. In February 2019, Ross started an industry PhD at UofA in conjunction with CSIRO and Wynns Coonawarra Estate as the industry partner. Ross’ PhD involved an investigation of the effect of rootstock on grape rachis composition, specifically in relation to methoxypyrazines.

In 2022, Ross was awarded a Nicolas Baudin internship in France with the University of Bordeaux where he explored the impact of oxygen on the chemical composition of wine under bottle and barrel aging conditions. After completing his PhD in February 2023, Ross relocated to Edinburgh, Scotland, where he is currently employed as a Knowledge Transfer Partnership Associate with Heriot-Watt University and Diageo Scotland ltd. In this role, Ross is exploring how American Standard Barrel (ASB) rejuvenation parameters impact oak stave chemistry, and the implications for the sensory and chemical profile of Scotch Whisky.

At the ACS: Methoxypyrazines (MPs) are readily extracted from grape berry and rachis during fermentation and can impart “green” and “herbaceous” sensory attributes to red wine.  3-Isobutyl-2-methoxypyrazine (IBMP) is the main contributor, but 3-isopropyl-2-methoxypyrazine (IPMP) and 3-sec-butyl-2-methoxypyrazine (SBMP) can also be present.

The concentration of MPs in both grape and rachis matrices is influenced by grafting of common Vitis vinifera scions to emerging rootstocks varieties. Ross shares the findings of his research into the contribution of rootstock, vine vigour, and sunlight to the concentration of methoxypyrazines (MPs)in Cabernet Sauvignon rachis and berries.

Roger has been involved in teaching and research related to grape and wine composition, scientific winemaking and sensor and measurement systems at the University of California, Davis for more than 40 years. He led the design and development teams associated with the world’s first LEED Platinum Winery constructed at UC Davis in 2010. He is an Emeritus Distinguished Professor in the Department of Viticulture and Enology and works as an advisor to innovative grape and wine organizations throughout the world.

He received his B.Eng. and PhD in Chemical Engineering from the University of Melbourne and spent most of his professional career in the Departments of Viticulture and Enology, and of Chemical Engineering, at the University of California, Davis, CA, USA. He is known as the primary author of the Principles and Practices of Winemaking, which was awarded the OIV Prize in Oenology in 1998, translated into three languages, and which continues to be used and referenced more than 25 years later. He is known to many winemakers and researchers due to teaching short courses throughout the world and presentations at international conferences. He is a member of the Jurade de Saint Emilion.

At the ACS: Streaming in from the USA, Roger addressed delegates at the Australian Cabernet Symposium 2024, highlighting the features of the Self-Sustainable, Zero-Carbon, LEED Platinum, Research Winery (and what it means for Precision in research winemaking and the Future of Cabernet Sauvignon).

The Research Winery at the University of California, Davis was conceived to overcome limitations in small-scale winemaking processes typically experienced in scientific experiments. 152 identical fermenters were designed, capable of precise control of juice and skin temperature, and reproducible automated pump overs for mixing of 1/2 tonne grape lots. When utilised for replicated, reproducible regional grape-to-wine research, as many as 50 individual vineyard lots can be fermented at a time.

Today, juice density, temperature, redox potential and model characterisation and prediction of all fermentations, can be viewed on a phone in front of each fermenter and anywhere in the world, in real time. Examples of Malbec and Pinot noir studies across large geographical distances will be presented and their importance for future studies with Cabernet Sauvignon will be discussed.

Chilean by origin and an agricultural engineer from the Catholic University of Chile, in 2004 Rodrigo arrived in France to complete a Master of Science in Viticulture and Enology at the ENSA in Montpellier, in addition to a French Enologist Diploma. He then worked in wineries such as Château Brane-Cantenac and Château Margaux, among others, until he became Technical Director of Château Kirwan, Grand Cru Classé de Margaux.

At the same time, Rodrigo also started working as an international consultant, participating in projects such as the development of a new wine region in Sonora (Mexico), working in the Maipo Valley (Chile) and conducting terroir studies in Nova Scotia (Canada).

These experiences led him to the role of International Technical Director for the Moet-Hennessy wine division, LVMH group, with wineries in seven countries (France, Australia, New Zealand, China, Spain, Argentina, and USA). Following this, he set up his own consulting company, Fine Wines & Terroir, based in Bordeaux, where to this day he consults on terroir, viticulture, enology, and due diligence, in France and other countries, intervening at all stages of wine production, with an integrative and international vision adapted to each reality.

At the ACS: Climate change poses new and increasingly important challenges to red wine production around the world. While this reality is an advantage in colder regions, in warmer regions it has become a major concern for producing quality Cabernet Sauvignon wines. Vineyard management, adapted to terroir and climate research, with adapted winemaking techniques, always oriented towards a high-quality wine, are imperative. Rodrigo will share his experience of how countries facing these challenges are adapting in order to continue to produce high quality Cabernet Sauvignon wines.

At the ACS: With the recent shrinking of the red-dominant China market and the consumer drift away from red wine globally, plus the longer-term impacts of climate change, what is the future for Cabernet, particularly in the regions where that variety dominates, most notably Coonawarra and also Margaret River?

Kym’s presentation highlights key aspects of the evolution of Cabernet Sauvignon’s place in the Australian wine industry using a comprehensive new annual dataset that covers the past 23 vintages. This data will help to address questions concerning the future of this noble variety in Australia given pertinent market developments nationally and globally.

At the helm of one of Margaret River’s founding wineries, Vanya Cullen’s passion and innovation are driving the winery – and the region – into the future. Having begun winemaking at Cullen Wines in 1983, since taking the reins as Chief Winemaker in 1989 and Managing Director in 1999, Vanya has transformed the family business into one of Australia’s best boutique wineries and most environmentally sustainable vineyards. She’s a pioneer of biodynamic grape-growing, an award-winning winemaker and respected wine show judge on both the national and international stage.

Thanks to Vanya, Cullen Wines is organic and biodynamic certified and was the first winery in Australia to be certified 100% carbon neutral. Her deep respect of the land brings these holistic principles into the winery too, gently handling hand-harvested fruit, fermenting using wild yeast and religiously following the biodynamic calendar.

Vanya has been named Winemaker of the Year by Qantas/The Wine Magazine as well as Woman of the Year and Green Personality of the Year by UK Drinks Business Magazine. In 2015, she was inducted into the Australian Business Women’s Hall of Fame, and in 2021 Vanya received Halliday’s 2022 Wine Companion Inaugural Viticulturist of the Year Award, as well as being named ‘Outstanding Viticulturist’ at the 2021 Delicious Magazine/ Harvey Norman Produce Awards. In 2023, Vanya joined the ranks of her mother and father, by also being a recipient of the Order of Australia for her services to viticulture and oenology.

At the ACS: Vanya shares the Cullen story, key learnings for Cabernet Sauvignon, and how they are preparing for the future, highlighting the evolution and benefits of biodynamic practices in her vineyards and winery.

With climate change at large, there is a priority to reduce emissions at Cullen in alignment with the Paris agreement, grow in the vineyard and property carbon neutral offsets, by carbon farming projects to produce ACCUs, in order to provide a sustainable way forward for winegrowing.

Lishi Cai is a passionate researcher who recently completed her Ph.D. in viticulture at the University of Adelaide. Her doctoral research continues to explore the causes of late-season berry shrinkage, which is a pertinent problem for winegrowers, especially for certain varieties (e.g., Shiraz and Cabernet Sauvignon). Comparisons were made between less and more susceptible varieties to infer metabolic control. Temperature was investigated as a primary abiotic variable, along with interactions with the degree of ripening on the incidence and severity of cell death. Hypoxia and ethanol production were investigated as physiological symptoms or precursors to cell death. She also explores possible agronomic treatments (such as anti-transpirants) that would be hypothesized to ameliorate this shrinkage.

At the ACS: Berry shrivel at full sugar content is becoming increasingly common in Australia and also in Europe for certain varieties. It can result in yield loss of up to 30% and high sugar concentration in juice. Shiraz and Cabernet Sauvignon are particularly prone to this phenomenon.

Lishi explains the predictors of cell death and berry shrivel and how an innovative “berry breathalyser” that monitors ethanol production in berries can indicate cell death before shrivel, with key learnings for Cabernet producers uncovered.

Vinay Pagay is a Senior Lecturer in Viticulture at The University of Adelaide, Australia. Vinay received his doctorate at Cornell University (USA) in 2014 where he worked on the development of novel tools for plant water sensing.

Vinay also holds a degree in computer engineering from McGill University (Canada). His basic and applied research lie at the intersection of grapevine ecophysiology and vineyard technology. His current applied research is looking into the use of proximal and remote sensing tools to obtain high spatial and temporal resolution data of both biotic and abiotic stresses in vineyards, as well as for precision irrigation scheduling in vineyards. Vinay is a co-inventor of the microtensiometer (commercialized by FloraPulse) and has co-founded Athena IR-Tech, a startup company out of the University of Adelaide that develops proximal crop water status sensors.

At the ACS: Dr Vinay Pagay provided delegates of the Australian Cabernet Symposium an insight into agriculture technology (AgTech) and the future of irrigation management in vineyards using continuous vine-based sensors to simultaneously increase water use efficiency and grape/wine quality. Presenting on how the challenges of vineyard irrigation motivated the development of Athena IR-Tech’s TranspIR irrigation scheduling sensors. The sensors employ proximal infrared technology to continuously measure canopy temperature and, together with ancillary environmental data, provide a daily index of vine water status.

Vinay demonstrates how this index simplifies irrigation decision-making and scheduling and in both premium and commercial vineyards in a diverse range of climates and with contrasting production goals. He also provides a glimpse into the future of irrigation management in vineyards using continuous vine-based sensors and show how these can optimise irrigation applications to simultaneously increase water use efficiency and grape/wine quality, sharing his findings from Coonawarra and various trials around South Australia.
