This book describes the frightening nets of corruption that exist around the olive oil market. The author tells about his experiences tasting different kinds of oils, and finding the supermarket oil very gross tasting and even dangerous for the health. He states that the olive oil producers cut the good oil with other seeds and chemically wash the bad odors. He says that there are still very few honest oil makers, but they struggle to survive as their oils are really expenisve. He describes his visits to some of these honest oil makers, as well as the terrible consequences of bad oil marketing: fake oil has killed 30 times more people than fake alcohol. Finally, he gives some advice on buying good oil: buy at the mill, preffer dark glass bottles and look for recent harvesting dates.
