Extra Virginity by Tom Mueller is a fun and informative book on olive oil. He also runs a website called Truth in Olive Oil: http://www.truthinoliveoil.com/ http://www.truthinoliveoil.com/ His page on supermarket olive oils has been really helpful for me - I haven't gone wrong with any of his picks. In particular I've liked the California Olive Ranch, Kirkland Signature Extra Virgin Toscano, and Trader Joe's Premium 100% Greek Kalamata. Another Greek oil we picked up at random at Rockridge Market Hall in Oakland: Terra Creta Early Harvest (November 2015). A bit more expensive than the ones above, but very tasty!
