italyMONDO!’s Olive Oil 101
Two weeks ago, in a post about Olive Oil and La Cucina Italiana, we left off daydreaming about all the wonderful ways olive oil is used in Italian cooking. But good food and reveries aside, there are some basic facts about olive that will help you make the best of that freshly pressed oil you’ve just brought home from the frantoio. And with so many different olive oils to choose from at the store, how do you choose the best one? Once you’ve brought it home, how should to store it to keep it fresh from the first to the last drop? Read on to learn some handy olive oil tips.
Types of Olive Oil
With all of its health benefits, olive oil has received a great deal of press in recent years, and many know already that Extra-virgin Olive Oil (Olio Extravergine di Oliva) offers best quality, flavors and nutrients. To be labeled Extra-virgin, the olive oil must be produced in what is termed a “cold press” where heat during pressing doesn’t raise above 80° F (27°C). Acidity levels also determine the quality of the oil. Extra-virgin oils must have an acidity level lower than 1%. Oils with an acidity level between 1-2% with a nice flavor and color are often labeled as Virgin Olive Oil (Olio Vergine di Oliva). Oils with acidity levels between 2-3.3% are labeled Ordinary Virgin Oil (Olio di Oliva Vergine Corrente), and are often used for frying or cooking where the flavor of the oil is not as important. Any olive oils produced with acidity levels over 3.3% are termed Olio Lampante (named because it used to be used to light lamps!) and are not used for cooking. Nothing is wasted during olive pressing, and what remains of the olive pulp after pressing, called sansa, is often burned for fuel or can be sold to olive refineries that use chemical solvents to extract even more oil. The oil produced by this method is labeled Olio di Sansa in Italy and it is a much lower quality product, often lacking in flavor.
A good olive oil flavor depends not only on the acidity and production methods, but also on the type of olives used and on the particular location and seasonal climate where they are grown. Some of Italy’s regions are geographically quite diverse, which means that oils produced in the same region near the sea can differ significantly from those produced in more mountainous areas with cooler temperatures. Colors and flavors of oils vary from dark green to light golden and strong and pungent to delicate and fruity. For example, the fine oils made with the local Dritta olives in the provinces of Pescara and Teramo in the Abruzzo region are known for their rich and fruity aroma, while those from the neighboring Molise region made with the local Gentile di Larino olives offer a delicate flavor with a slight aftertaste of almonds. Heading further south, olive oil from Puglia and Calabria can be quite peppery with an intense aroma perfectly complementing the spicy local dishes. This range and variety of flavors is what makes sampling olive oil from the top of the boot to the toe such an exciting culinary adventure.
Buying and Storing Olive Oil
The first thing to keep in mind when selecting an olive oil is to remember that it is a delicate product and must be packaged and stored carefully. Olive oil does not improve with age as wine does, and it is best used within a year after production. Take the time to check for a date while shopping and fresher flavors will be your reward. Like any fat, olive oil can become rancid or loose its flavor and health benefits if it is not stored properly. The two main enemies of olive oil are light and heat. Look for olive oil packaged in tins or tinted bottles rather than clear ones, and remember never to store your olive oil in a sunny spot! The ideal temperature for olive oil is between 58-64° F (14-18° C), so be sure not to store it next to your stove as the heat can quickly change the oil’s quality. Too cold is also no good, so get that olive out of the refrigerator!
Olive oil easily absorbs aromas, making it an ideal base for perfumes and for aromatic oils, such as those commonly made in Italy like chili pepper oil, rosemary oil and citrus oils. However, this also means that olive oil quickly absorbs bad odors as well. Be sure to store your oil in a container that has been thoroughly cleaned and dried, and keep it away from strong smells.
