Archaelogists and anthropologists (especially ethnologists) have for many years realised that man"s ingestion of alcoholic beverages may well have played a significant part in his transition from hunter-gatherer to agriculturalist. This unqiue book provides a scientific text on the subject of "ethanol" that also aims to include material designed to show "non-scientists" what fermentation is all about. Conversely, scientists may well be surprised to find the extent to which ethanol has played a part in evolution and civilisation of our species.
