The fraud and pretty much entire lack of regulation described in today's olive oil market is outrageous. Mueller weaves history and more scientific descriptions together with the tale of oil adulteration and fraud nicely, though sometimes I wished for more of one or the other. This messy state of affairs for consumers is what really made an impact, so I was happy to see the appendix with info on how to find reputable supplies of olive oil.

A few quibbles Which take it from 4 to 3 stars, well 3.5 if that was possible.
1. No index. This is non-fiction with a lot of information packed in a relatively concise (206 text pages) package - an index would have been helpful.
2. Font - greeting card font used, annoying to read
3. The appendix on choosing olive oil. Great to have this, but there is so much here, organized randomly - would have made a solid final chapter.
