Choices in the Vineyard - Part II
With Marc Greven, Gregory Gambetta
Tuesday Aug 13 2024
Introduction
Wine Scholar Guild is pleased to bring you this 5-session course developed in conjunction with Agro-Bordeaux, a public viticulture and enology school under the authority of the French Ministry of Agriculture. The curriculum explores terroir from the ground up, and is designed to give you a thorough understanding of some of the fundamental principles of viticulture, the various challenges faced by growers in the vineyard, and how the fine wine regions of the world are adapting to the changing climate to preserve the quality of their fruit.
The course is split into 5 sessions, the first 3 sessions are in Part One, and the remaining 2 sessions can be found in Part Two here.
Summary:
Session IV
In this lecture, Dr Marc Greven will discuss the use of cover crops in the vineyard and the influence on the soil an dhence the vine and wine quality. Cover crops can work both in favor of the vines or against them depending on the local soil and climate conditions. These influences will have to be well understood in order to make the right choices when planting cover crops. The influence of cover crops will be discussed in the context of soil protection, their influence on vine water availability as well as the competition for nutrients, and all that related to vine productivity and wine quality.
Session V
Water is the driving force of all nature, said Leonardo da Vinci. In this webinar, Dr. Greg Gambetta will explore the relationship between vines, soil, and hydric stress. Just how does water availability, or lack thereof, impact the vine? What is “drought tolerance” and how does water availability impact vine health and wine quality? Drought is plaguing many of the wine regions of the world. This webinar will address a hot topic with an eye to the future.
