THE GRAFTED GRAPEVINE (a three-part series) 

Welcome back to our three-part viticultural series that takes a deep dive into the grafted grapevine. Thomas Dormegnies, of the highly respected Bérillon Nursery in France, will share his expertise and experience to help you discover how grafted grapevines are produced, the impact of high-quality vine plant material on viticulture, how diversity and sustainability in the vineyard starts from the grafted grapevine plant itself and finally the importance of rootstocks.

Part III: Rootstocks, a solution for climate change? (September 6, 2021)

For the final webinar of the series, Thomas will focus on rootstocks, the living link between scion and soil. Bérillon has a collection of 20 different rootstock varieties that can accommodate a wide variety of different pedological and climatic constraints. One rootstock does not fit all! Thomas will discuss this link between rootstock and terroir, and how they may impact flavor. As climate continues to change, as farming practices continue to change, rootstocks have been and are increasingly key to vine health. Find out why!

Please find below the abstracts of the two other webinars in this series: 

Part I: How to produce a grafted grapevine? (aired on June 28, 2021, access to recording in our webinar archive)

Join Thomas Dormegnies of Bérillon Nursery as he walks us through grafted grapevine production from start to finish. Learn the steps, the vocabulary, and the thought processes behind the technique! Thomas will discuss reception and preparation of scions and rootstocks, whip and tongue (English cleft) grafting, stratification, planting, maintenance, sorting, hot water treatment and storage before delivery. This webinar will cover the basics in preparation for a deep dive into cloning and breeding on July 5.

Part II: How to Maintain Diversity?

Join Thomas for Part II of the Grafted Grapevine series as he explores the genetic mass selection of grape varieties intended for grafting. Bérillon’s team of breeders only source its scion material from old vine vineyards in order to identify, build-upon and preserve intra-varietal genetic diversity. The selected cuttings are tested to make sure the specimens are virus-free before being propagated. These same steps are carried out for international, regional, heritage and forgotten grape varieties.  The next session will focus on rootstocks and their relationship to soil and climatic stresses.

Presenter: THOMAS DORMEGNIES

Vine Breeder and Engineer at Bérillon Nursery 

Thomas graduated from the Agronomic Engineering School of Rennes in Plant Selection and Improvement and of Montpellier in Viticulture-Oenology, He has been working as a vine breeder in the wine nursery for 18 years. This work of plant archeology, also called "mass selection", consists of identifying future candidates found in old vineyards and breeding them in the nursery.

Passionate about plants, he roams the old vineyards of France and Europe in search of the widest possible genetic diversity, whether for the most multiplied international grape varieties or "modest" or forgotten grape varieties. This work requires a solid knowledge of plant physiology as well as ampelography, or the art of distinguishing grape varieties from one another using leaves, twigs or fruits.

His activity within the Bérillon Nursery (www.lilian-berillon.fr) also leads him to follow the planting projects of their clients, advising them both on the choice of their plant material and on the management of their soils. This is a comprehensive approach that links agronomy and pedology for the sake of sustainability and transmission of plantations.

Thomas is also a winemaker along the French Atlantic coast, he therefore has complete experience of the wine industry, from the selection of future vines to the vinification and marketing of the wines.

Rick's Pick: University of Tarragona instructor and winemaker, Antoni Sanchez-Ortiz focuses on climate change and how viticulture must adapt in Spain’s DOQ Priorat region.

The mesoclimate determines climatic differences due to the topography of the Priorat and that give rise to local modifications or changes that can affect to more or less ample extensions. Factors that condition them include distance to the sea, altitude, orientation, exposure, and latitude. Between nearby municipalities, noticeable differences in temperature, precipitation, insolation and thermal amplitude can be seen, which affect the processes of growth, bud breaking, fruit formation, ripening and, ultimately, the composition of grapes. The prediction of an interval of concentrations of color and tannins would be of utmost importance to define qualities and styles of wine, given the great inter-parcel variability observed in plots of Grenache and Carignan vines within the Priorat DOQ.

Presenter:  Antoni Sánchez-Ortiz

Here is his bio, as narrated by Antoni: 

I was born in December 4th, 1978 into a family with few financial resources in a small valley in the Spain’s Pyrenees. Although my parents never had the chance to go to school, I had some talent to study science and so continued my studies until college. After five years in college, I majored in analytical chemistry and more particularly to assess the degree of chemistry in the University of Barcelona. After I worked in corrosion of automobile engines and intercoolers using the Swaat Tecnique, at Frape Behr. Quickly I moved into the development of a GC-MS (gas chromatography-mass spectroscopy) methods to determinate fatty acid composition from raw materials (mainly palm and coconut oil), where I worked at Henkel Düsseldorf plant in Germany for one year after obtaining a scholarship.

It was there almost by chance where I took a course of wine tasting and there began my interest in the discovery of quality wines. Consequently I fell in love with fine wines. In the following years, after studying enology within the University Rovira i Virgili in Tarragona (Spain) and the University Victor Segalen in Bordeaux. I  graduated as a winemaker at 23 years of age. For 18 years now I have worked full time within the demanding context of producing world-class wines, both as a winemaker and as a viticulturist in the renowned appellation of Priorat,Spain. For many years I have also worked closely with the renowned French consulting enologist Claude Gross, and have travelled to California to study the Pinot Noir blending techniques of Sea Smoke Cellars, the acclaimed Pinot Noir producer near Santa Barbara, California.  I like obtaining outstanding fine wines with a unique personality, making a superb red wine in the Priorat wine growing region, as an expression of varietal and site showcases the best which region’s true native character. Currently, with the consulting company I am also committed to producing one of the high-end, handmade organic olive oil in Spain’s Pyrennees. My conviction that great wine results from an intimate knowledge of the land arises from additional experience in vineyard management and climate warming studies as a PhD candidate with the Viticulture Department at the Faculty of Enology in Tarragona.
