Hello! You've hit the Keith Grainger wine website. Here you can find out about me, my books, and about forthcoming events. There are also informative articles on winemaking and quality in wine.

You can also learn about wine faults. These pages will change regularly and I will add more informal pieces to my blog. Whether you are a wine professional, or just love a glass and want to discover more, there's something here for you.


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.


Great News: I have just heard that the book has won the 2022 Prix de l'OIV (OIV Award) for the Oenology Category. The OIV is an intergovernmental organisation whose functions include setting the standards for grape growing and winemaking globally. I will be receiving the award in Bordeaux on September 30th. Following my success in the Gourmand Awards for The Best Wine Book for Professionals, I am over the moon! The book had already won the Gourmand Award for the 'Best Wine Book in the World for Professionals'. It is available in hardback, as an e-book and also on Kindle.

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.
