Olive Oil Odyssey

You know it’s good for you. Now it’s time to discover some of olive oil’s subtler nuances.


Olive oil is like wine. It can contain a multitude of subtle aromatic and flavor differences, from flowery and fruity to earthy and nutty. There’s cheap stuff and pricey stuff, and price is often (but not always) a decent indicator of quality.

Most olive oil imported to the United States comes from Italy, Spain and Turkey, but olive oil is also produced in Greece, Portugal, California, Palestine, Australia, South Africa, France and Croatia. People like to debate which country produces the most delectable olive oils (“Italian is richest! No, Spain’s softer taste rules! Greece’s grassy quality is divine!”), but frankly, such preferences are intensely personal. Moreover, flavor varies not just by country, but by region within a given country, so it’s almost impossible to generalize.

As with wine, differences in flavor are also determined by variety of olive tree, soil and climate, and especially by how the oil is processed.

So how do you choose? Your first priority should be finding a good but affordable extra-virgin olive oil you like for everyday use. From there, you’ll want to experiment to find out what olive oils you like for special-use purposes like dipping, dressing, drizzling and marinading, or for recipes that call for milder and more robust oil flavors.

A great way to determine which olive oils you prefer is to purchase small bottles from different countries and producers and conduct a sample tasting. Either swirl a small amount in a cup and sip, or dip into the oil with a baguette. Note the different flavors and aromas. A strong, rich extra-virgin olive oil would pair nicely with grilled beef or white bean purée or drizzled on sautéed greens. A lighter one would complement fish, vegetable, pesto and pasta dishes.

In general, extra-virgin olive oil should have a deep-green or golden color. It may have a range of flavor undertones: fruity (which you can smell); bitter (which you taste on the back of the tongue); and peppery (which you feel in the back of the throat). Flavors you don’t want to find? Rancid, musty, burnt, muddy or vinegary, which indicate poor processing or storage.

Nutrition Know-How

  • Eating an olive-oil-rich “Mediterranean diet” has been shown to reduce the risk of chronic illnesses, such as heart disease, atherosclerosis, diabetes, colon cancer and asthma.
  • In one study, exclusive use of olive oil when preparing foods — as opposed to other fats — decreased the likelihood of coronary heart disease by an amazing 47 percent.
  • One tablespoon of extra-virgin olive oil offers nearly 45 percent of the recommended daily amount of monosaturated fats and about 4 percent of omega-3 fatty acids.
  • The chemical makeup of specific olives — their phenolic compounds — determines an oil’s pungency and offers antioxidant activity. Extra-virgin olive oil has higher levels of polyphenolic phytonutrients than more refined olive oils. They lower LDL or “bad” cholesterol and improve heart health.
  • Oleocanthal is a natural organic compound isolated from extra-virgin olive oil. It gives the oil its peppery bite, and its anti-inflammatory properties can help ward off chronic disease.
  • Olive oil’s green-gold color comes from chlorophyll and the carotenoid pigments beta-carotene and lutein, which are all antioxidants. Carotenoids also enhance the immune system.
  • The vitamin E in olive oil helps protect your cells from free radicals, and your brain from Alzheimer’s disease.

Kitchen Tricks

  • With the exception of high-heat deep-fat frying, using extra-virgin olive oil is the best choice for cooking, including sautéing, stir-frying, and for rubbing on meats when grilling and roasting. But avoid heating extra-virgin olive oil above 350 degrees F, because the unrefined particles within the oil will burn, ruining the taste and leading to possible toxicity (overheating can create polycyclic aromatic hydrocarbons, or PAHs, which are carcinogenic).
  • The fine, delicate flavors of extra-virgin olive oil make it the best choice when preparing salad dressings, marinades and dipping sauces, and when finishing prepared dishes, such as potatoes and vegetables, and seasoning most fresh-cooked items.
  • To preserve the most nutrients, add olive oil to foods after cooking, if possible.

More Ways to Enjoy

  • Instead of buttering bread, serve it brushed with mild-flavored olive oil — or simply place a small dish of oil on the table for dipping.
  • Drizzle a small amount of extra-virgin olive oil over fresh mozzarella, tomatoes and basil for homemade caprese salad.
  • For a basic crostini, generously brush small rounds of good-quality bread with olive oil and bake at 350 degrees F until golden. Toss fresh roasted red peppers with additional olive oil and basil, then serve the mixture on crostini.
  • Make your own olive-oil infusion by decanting oil into a small, dark bottle and then submerging a sprig or two of fresh herbs, plus salt and pepper to taste. Let flavors mingle for a couple of days in sealed bottle. Fresh infused oils are great on salads or in marinades and will keep for about a week in the refrigerator.

Keep It Fresh

  • Buy olive oil in dark, opaque containers. They cut down on exposure to damaging sunlight and grocery-store fluorescents, which can speed up the oxidation that causes oils to go rancid.
  • Elevated temperatures also speed oxidation, so once you’re home, store olive oil away from heat and light.
  • Any time you open a container, you let in air and speed spoilage. If you’re a heavy user, consider buying a big tin of olive oil, then pour a week’s worth into a small bottle and store it at room temperature. (Keep the rest in its original container in the refrigerator. Oil gets cloudy when refrigerated, but will become clear again at room temperature.)
  • It’s best to use olive oil within a few months of purchase. Studies show that at one year, olive oil’s nutrients have significantly declined.
  • Fresh olive oil has a fruity, pleasant smell. If it smells bitter or dusty or oily, it’s probably gone bad. Start over with some new stuff — and purchase a smaller quantity next time!

Red Snapper Scented With Orange and Olive Oil, Baked in a Foil Package

Makes four servings

Baking fish in foil packages keeps it moist and steeps it in the flavors of any added ingredients. Drizzling olive oil over hot fish just before serving creates an amazing aroma and deepens the flavors of the fish, herbs and vegetables.

  • Four (20-by-15-inch) pieces of aluminum foil
  • Four (4-ounce) skinless red snapper fillets
  • 2 tbs. fresh herb mix: chopped basil, parsley, chives and oregano
  • Two carrots, peeled and cut into 3-inch batons
  • One zucchini, cut into 3-inch batons
  • Eight Kalamata olives, sliced thin
  • One orange: zest and juice
  • 3 tbs. extra-virgin olive oil

Preheat the oven to 450 degrees F.

Season the fish on both sides with fresh herbs. Place one fillet on half of each piece of foil.

Top each fillet with four carrot batons, two zucchini batons, and one-fourth of the olives. Sprinkle with orange zest and drizzle with 1 tablespoon of orange juice over each fillet.

Fold each piece of foil in half over the fillets. Begin with a folded corner. Twist and fold the edges together to form a half-moon package. Seal the end tightly by twisting it. Repeat with remaining packages.

Place packages on baking sheet and bake for 10 minutes. Cut the packages open to serve and drizzle each with 2 teaspoons extra-virgin olive oil.
