Summary:

Of all the vineyard soils of the world, a dozen or so have acquired a designation of their own.

Examples are New Zealands Gimblett Gravels (with their astonishing rise to fame), the albarizas of Spains sherry district (made of tiny but crucial architectural marvels), Californias enigmatic Rutherford Dust, the cherished Kimmeridgian of Chablis, and the spectacular terra rossa of Australias Coonawarra. The names probably mean little to most people but to wine enthusiasts they are features to celebrate, prompting images of exceptional places and wines of distinction.

In WSG Live, Alex Maltman will explore the stories and the science behind these five examples of elite vineyard soils, with names that are legendary in the world of wine.

Presenter: Alex Maltman

Alex is Emeritus Professor of Earth Sciences at Aberystwyth University, in Wales, U. K. He has a decorated career in university teaching and research together with a long-standing interest in wine: for nearly fifty years Alex has grown vines and made wine at his home in Wales.

Alexs scientific curiosity has always questioned things about wine including, inevitably, the fashionable but poorly understood relationship between wine and vineyard geology. This has led to publications in both the popular press and academic journals, and to various international lectures.

Alex has contributed to a number of wine books, such as the Oxford Companion to Wine and the World Atlas of Wine, and is the author of the acclaimed Vineyards, Rocks, and Soils: A Wine Lovers Guide to Geology (Oxford University Press 2018)

Summary:

In Burgundy, the word "terroir" is frequently used to designate the subsoil which is thought to be responsible for the classification of the appellations from "regionales" to "grand cru. "

This same subsoil is also thought to delineate the puzzling mosaic of "climats" which sculpt the hillside vineyards and influence the wines of the Cote de Nuits' characteristics. This WSG Live will explore the nature of this rock and see if it corresponds perfectly to the specific vineyard plots which produce the very high quality and diverse nature of the wines... from Marsannay to Corgoloin.

Presenter: Francoise Vannier

As told by Francoise:

After studying both at university and the French Insitute of Petroleum (IFP, -Ecole Nationale Superieure du Petrole et des Moteurs-), I worked for an oil company until 2000, when my family moved to Burgundy. In this renowned wine country, I decided to transfer my geological skills to the study of terroir. I successfully completed a one-year diploma in Wine-tasting and Terroir at the University of Burgundy, (Dijon, France), and I now work as a consultant. My new career as a consultant began in 2003, and since March 2015, with Adama, a little company dedicated to vineyard terroirs. Since 2019, I also work for Terroir Invest, a society dedicated to the sale of vineyard estates.

I performed numerous studies in both the Cote de Nuits and Cote de Beaune, for the renewing vineyard of Dijon, and for Marsannay, Fixin, Gevrey-Chambertin, Morey-Saint-Denis, Chambolle-Musigny, Pommard, Santenay, Les Maranges, further south for Lugny (Maconais), or for Coulanges-la-Vineuse to the North (Yonne), but also elsewhere in France, especially with a starting project in the Val de Loire (Sancerre). I have also produced several preliminary technical reports to reclassify certain plots at a higher appellation level (communal for Lugny, 14 premiers crus for Marsannay, and a grand cru for Les Saint-Georges and other AOP). I also work for foreign estates (Chile, Japan, USA -California-, Italy... ) in order to characterize the soil and the subsoil, and for terroir expertise.

I have contributed to the geological chapters in Remington Normans (UK) book Grand Cru, to several articles in Le Rouge & le Blanc, La Revue des Vins de France, le Maagzine of Ficofi; I am now in-house expert for terroir geology in Bourgogne Aujourdhui. I drew the cross-sections of geological maps in The wines of Burgundy by Sylvain Pitiot and Jean-Charles Servant, and I have done some posters for the Saint-Vincent in Saint-Aubin (January, 2014). Most of my works are available through the educative website http: //monocepage. com. I provide information for CDs or websites for numerous estates, highlighting the characteristics of the terroir, and booklets for some appellations of both Cote de Nuits and Cote de Beaune. I was the subject of a four-page interview paper in the January 2014 issue of Decanter magazine.

Summary:

In order to understand better the specificities that led not only to the present-day landscape but also to the soil and subsoil nature and diversity of the French vineyard, a travel in the past times is necessary.

In order to understand all the key events that occurred during the hundreds of million years of geological history. Being aware that a lagoon, a tidal-influenced shoreline, a broad river, a collision between two tectonic plates, the occurrence of a tropical climate… or ice ages led to a better comprehension of the identity of each French wine growing region.

Since 2019, I also work for Terroir Invest, a society dedicated to the sale of vineyard estates.

I performed numerous studies along both Côte de Nuits and Côte de Beaune, for the renewing vineyard of Dijon, and for Marsannay, Fixin, Gevrey-Chambertin, Morey-Saint-Denis, Chambolle-Musigny, Pommard, Santenay, Les Maranges, further south for Lugny (Mâconais), or for Coulanges-la-Vineuse to the North (Yonne), but also elsewhere in France, especially with a starting project in the Val de Loire (Sancerre). I have also produced several preliminary technical reports to reclassify certain plots at a higher appellation level (communal for Lugny, 14 premiers crus for Marsannay, and a grand cru for Les Saint-Georges and other AOP). I also work for foreign estates (Chile, Japan, USA -California-, Italy...) in order to characterize the soil and the subsoil, and for terroir expertise.

Sharing my scientific experience, my expertise and my knowledge of the Burgundy vineyard either in French or in English, with students (the University of Burgundy, Burgundy School of Business, Lycée Viticole de Beaune, ISARA…) winegrowers, people working in and around wine, and for wine-lovers (e.g. the “Master class” of Allen Meadows, the “Masters of Wine”, the “Académie du Vin” of Tokyo and Paris, Jasper Morris MW (Berry Bro^s and Rudd) and for Anthony Hanson (Christie's in London) la Paulée de New York (Daniel Johnes) and so many others…) is a key goal in my work, which has become more of a vocation than a profession. Burgundy needs ambassadors to promote a scientifically grounded in-depth knowledge of terroir. I have given many presentations and organised field trips both in French and in English for the scientific community (International Terroir Congress, 2012), wine professionals, tourists and wine-lover associations. 

I have contributed to the geological chapters in Remington Norman’s (UK) book “Grand Cru”, to several articles in “Le Rouge & le Blanc”, “La Revue des Vins de France”, “le Magazine” of Ficofi; I am now an in-house expert for terroir geology in “Bourgogne Aujourd’hui”.

Summary:

Terroir has often been defined as an untranslatable French concept with somewhat mystical attributes.

Some wine experts view terroir as an over-hyped myth, while others consider it to be primarily responsible for the unique sensory characteristics and distinctiveness of wines.

This webinar will explore how the concept of terroir has evolved over time, and how it is currently defined.

Examples of the misuse of the term for marketing will be highlighted as well as the scientific validation of terroir.

Presenter: Dr Kevin R. Pogue

Dr Kevin R. Pogue has been a professor in the Department of Geology at Whitman College in Walla Walla, Washington for over 30 years.

Dr Pogue’s research is primarily focused on variations in growing conditions related to vineyard topography, climate, and soil chemistry.

He has presented papers at national and international terroir conferences and his research has been featured in the New York Times and on National Public Radio's "Science Friday". 

He has authored five petitions for federally-sanctioned American Viticultural Areas (AVAs) and was honored with the Walter Clore award by the Washington State Wine Commission for his “significant dedication to the advancement of the Washington wine industry as an ambassador, mentor, and champion of Washington wines.” 

Dr Pogue provides vineyard site evaluations, AVA petitions, terroir-related web content, and promotional and educational materials through VinTerra, his consulting business.

Summary:

This webinar will dig into the basics of rocks and soil, and their respective roles in defining a site’s terroir. This discussion will give you the terms, tools, and scientific foundation to discuss terroir like a pro.

We will explore the different types of rocks, how they form, and in which wine regions across the globe you can expect to find them.

We will also discuss the difference between bedrock, soil, and subsoil in order to understand how soils form and how they support plant life.

Finally, we will review the concept of terroir, and how the geology of a region can influence the character of its wine.

Summary:

Our fifth edition of WSG Live features the Chilean terroir consultant Dr. Pedro Parra.  Join Andrew Jefford for a passionate discussion about Pedro's work and his ideas surrounding terroir!

Since earning his doctorate in 2004 in Terroirs Viticoles from the Ecole d'Agriculture de Grignon (now part of AgroParisTech), Pedro has travelled the world consulting for many of today's leading wineries, including Liger-Belair and Roulot in Burgundy, Biondi-Santi and Argiano in Montalcino, Quintessa in Napa, Marengo in Barolo, Comando G in Gredos and Altos Los Hormigas in Mendoza. 

His approach to soil studies is unique, combining as it does scientific analyses and detailed site mapping with an intuitive understanding and original reasoning, and always validating his insights with tasting in his quest for minerality (a term he uses freely), tension and freshness. 

Since 2013, too, he has made his own wines in his native Chile, in Itata.

Summary: 

Can you taste ‘minerality’? What do we mean by ‘terroir’? Where do aroma and flavour come from? Is too much attention paid to the role of the soil in discussions of the aromas and flavours of great wines? How rare are truly great wine-growing sites? These are some of the questions we aim to discuss in the upcoming Meeting of the Minds on November 25th.

Wine Scholar Guild Academic Advisor Andrew Jefford, speaking from France, will be bringing together a panel of key thinkers, educators, writers and experts in four countries to talk through these and other issues. Wales-based Professor Alex Maltman has had a forty-year teaching career, and now divides his time between writing about the relationship between geology and wine production as well as the influence of geology on other beverages and tending his own vineyard. California-based Professor Hildegarde Heymann teaches sensory science within the viticulture and oenology department of UC Davis, one of the world’s leading wine-educational institutions. Former plant scientist and science editor Dr Jamie Goode, speaking from the UK, writes, blogs and tweets about wine and wine science via his own Wine Anorak website as well as for The World of Fine Wine and other publications. Finally, speaking from Turckhiem in Alsace, comes Olivier Humbrecht MW, one of the world’s leading exponents and practitioners of site-sensitive winemaking and a widely acclaimed viticulturalist and winemaker.

This Meeting of the Minds aims to explore one of the most misunderstood yet also the most important topics in today’s wine world.

Host: Andrew Jefford

Andrew, Academic Advisor to the Wine Scholar Guild, has been writing about wine since 1988, notably for The Evening Standard and The Financial Times among other UK newspapers. 

He has columns in every edition of Decanter magazine and World of Fine Wine magazine, and is co-chair of Decanter World Wine Awards and vice-chair of Decanter Asia Wine Awards.  His books include The New France, Whisky Island and Andrew Jefford’s Wine Course.

Summary:

Clay is very familiar: in garden soils, for modelling toys, baked as bricks and tiles, pots and plates. It’s very widely used commercially: in landfill linings, drilling muds, animal housing, insulation, explosives, medicines, cosmetics, etc. etc. And yet it’s a rather mysterious substance. What is it exactly? What is it made of? Why does it behave in such unique ways?

In this WSG Live I will explain the basics of clay and clay soils. In particular I will show how two fundamental properties of the minuscule flakes that constitute clay underpin its multifarious significance. In the wine world this includes critical influences on the nutrient status and the drainage properties of vineyard soils, and also its use for such things as a rooting medium for vine cuttings, a sunscreen on vine foliage, and a wine clarifying agent. Clay foundations can affect the very stability of winery buildings. Even fermentation vessels, in recent years so fashionably made of oak or stainless steel, are for some producers now shifting back to the material used 8,000 years ago – clay.

It’s a bewildering array of applications, but an understanding of the basics of what clay is goes a very long way to explaining just why it’s such a special material and so important in the world of wine.

Alex Maltman is Emeritus Professor of Earth Sciences at Aberystwyth University, in Wales, U.K. Besides a long and decorated career in academic teaching and research, which has involved some of the Earth’s high mountains, drilling below the floors of the deepest parts of the oceans, and a lot of geological matters in between, for over forty years he has grown vines and made wine at his home in Wales.

His scientific curiosity always questioned things about wine, and particularly its much-mentioned relationship with vineyard geology. This led to research on vineyard soils on four continents and eventually to presentations at international conferences, workshops and masterclasses, together with publications both in the popular press and academic journals. Alex was responsible for the geological entries in the Oxford Companion to Wine and has advised on the geological content of a number of wine books, including the World Atlas of Wine. He is author of the widely acclaimed volume: “Vineyards, Rocks, and Soils: A Wine Lover’s Guide to Geology”.
