Step 1
Learn the different grades of olive oils
Olive oils, obtained by pressing tree-ripened olives, are graded according to degree of acidity. Here are descriptions of various grades of olive oil:
• Pure olive oil: An olive oil that has been filtered and stripped of much of its flavor and color. It has up to 3 percent acidity.
• Extra-virgin olive oil: The highest class of oils, these must, by regulation, contain less than 1 percent acidity. They must be mechanically, not chemically, produced, and are never subjected to heat during production. Milling and oil extraction occur within 24 hours of the olive harvest. These oils come in a wide range of colors, flavors and textures.
• Virgin olive oil: These oils range in acidity from 1.5 to 2 percent. Because of their less distinctive flavor, they are less expensive and a good choice for baking.
• Light olive oil: Contains a low amount of extra-virgin oil in the mix and up to 3 percent acid. Light does not mean lower in calories but, rather, less flavor.
