About

Wine Faults and Flaws: A Practical Guide

From the back cover:

An essential guide to the faults and flaws that can affect wine.

Written by the award-winning wine expert, Keith Grainger, this book provides a detailed examination and explanation of the causes and impact of the faults, flaws and taints that may affect wine. Each fault is discussed using the following criteria: what it is; how it can be detected by sensory or laboratory analysis; what the cause is; how it might be prevented; whether an affected wine is treatable, and if so, how; and the science applicable to the fault.

This book will prove invaluable to winemakers, wine technologists and quality control professionals. Wine critics, writers, educators and sommeliers will also find the topics highly relevant. The wine-loving consumer, including wine collectors will also find the book a great resource and the basis for discussion at tastings with like-minded associates.

Keith is an excellent and entertaining presenter, highly knowledgeable, and full of irreverent humour. He has the advantage over many other presenters of actually having made wine in several countries, including South Africa, Turkey, and Cyprus, over many years.
