Brief
More than 95% of olive oils are imported. Great olive oils are made in dozens of countries around the world including Spain, Italy, Greece Portugal, Tunisia and others. Look for fresh oil as indicated by a harvest date. If it smells and tastes like fresh olives and has some nice fruitiness and bitterness, you likely have the real thing.
