Practical Handbook of Grapevine Pruning (English edition) by André Crespy

The Practical Handbook of Grapevine Pruning by André Crespy is an authoritative resource that delves into the art and science of grapevine pruning, an essential practice in viticulture. This comprehensive guide is designed for vineyard managers, viticulturists, and wine enthusiasts who wish to deepen their understanding of vineyard management and enhance the quality of their grapes.

Introduction

Pruning is a critical practice in viticulture that directly influences the quantity and quality of the grape harvest. Over centuries, wine growers have refined their methods to suit the specific conditions of different wine regions, ensuring consistent and satisfactory yields. This book provides a historical context for pruning, exploring its evolution alongside the Appellation d’Origine Contrôlée (AOC) system, and addresses modern challenges posed by climate change.

For instance, the accelerated ripening of Grenache in southern French appellations, such as Côtes de Rhône, presents unique challenges that require innovative pruning techniques. The book underscores the importance of adapting traditional practices to modern realities, particularly in regions facing rapid changes in climate.
