Test Your Olive Oil Knowledge: An Olive Oil Trivia Quiz

How many trees does it take to make one bottle of extra virgin olive oil? Please keep reading to find out. … We’ve just begun harvesting our olives. And we’ve just wrapped up our annual Harvest Retreat.  We give chefs, big customers, and culinary partners a  tour of how we harvest and crush olives into EVOO at our groves and mill in Artois, in northern California.

On Tuesday and Wednesday mornings a big group of us climbed on a bus and drove about 100 miles north on the interstate, to Artois (don’t blink or you’ll miss it). People chatted and got to know each other during the ride. I also talked about our olives, our mill, and other ins and outs of the business.

One more thing: I gave an olive oil trivia quiz. I thought it would be good to share it with you. Sorry, there’s no prize. But we hope you learn something new about our company and the olive oil business.
