Olive History
The olive, botanically-known as Olea europaea, dates back to 17th century B.C where it first appeared in print in Egyptian records. Olives were mentioned numerous times in the Bible. The word comes from the Latin olivea which first appeared in English around 1200 a.d.Since the olive is native to the Mediterranean area, it is no surprise to learn the largest producers in the world are Italy and Spain, where olives are a diet mainstay.
Olive Oil Labeling
Olive oil labels can be confusing. Be aware that the only terms recognized by the U.S. labeling laws are Fancy and Super Fancy.
The United States is not a member of the International Olive Oil Council (IOOC) which sets strict standards on olive oils to ensure better products.
The California Olive Oil Council offers a certification program to assure oils with the extra virgin label actually comply with the strict IOOC standards. Those that qualify can carry a special seal.

Olive Oil Storage
Store olive oil in a cool, dark place for up to 6 months or in the refrigerator up to a year. Check the label for a bottling date for freshness. Olive oil does not improve with age like fine wine and is best when used during the first 6 months of pressing.
Refrigerated or very cold olive oil will become cloudy, but will clear up when brought to room temperature. Be sure it is kept in an airtight container.
In general, use higher quality forms of olive oil for flavor foremost, and lower grades for high-heat applications.

Types of Olive Oil
The best olive oil is a blend of oil from a mixture of red-ripe (not green and not fully ripe) olives and a smaller proportion of oil from green olives of a different variety.
When purchasing olive oil, it is important to check labels for the percentage of acidity, grade of oil, volume, and country of origin. The level of acidity is a key factor in choosing fine olive oil, along with color, flavor, and aroma. Here are the different categories of olive oils:
• Extra virgin olive oil: cold-pressed result of the first pressing of the olives, with only 1% acid; considered the finest and fruitiest, and thus the most expensive; ranges from a crystalline champagne color to greenish-golden to bright green; generally, the deeper the color, the more intense the olive flavor.
• Virgin olive oil: also a first-press oil, with a slightly higher acidity level of between 1-3%.
• Fino olive oil: (meaning fine in Italian) is a blend of extra virgin and virgin olive oils.
• Light olive oil: This version contains the same amount of beneficial monounsaturated fats as regular olive oil, but due to the refining process, it is lighter in color and has essentially no flavor. This makes it a good choice for baking and other purposes where the heavy flavor might not be desirable. This process also gives it a higher smoking point, making it a prime candidate for high-heat cooking.

Olive Types
The only difference between green olives and black olives is ripeness. Unripe olives are green, whereas fully ripe olives are black.
Olives are cured or pickled before consumption, using various methods including oil-cured, water-cured, brine-cured, dry-cured, and lye-cured.
Green olives must be soaked in a lye solution before brining, whereas ripe black olives can proceed straight to brining. The longer the olive is permitted to ferment in its own brine, the less bitter and more intricate its flavor will become. Green olives are usually pitted, and often stuffed with various fillings, including pimientos, almonds, anchovies, jalapenos, onions or capers.
Black olives are graded into sizes labeled as small (3.2 to 3.3 grams each), medium, large, extra large, jumbo, colossal, and supercolossal (14.2 to 16.2 grams). Black olives contain more oil than green.
Unopened olives can be stored at room temperature up to 2 years. Opened olives should be refrigerated in their own liquid in a non-metal container and will last up to several weeks after opening.
