(Reply #9 at the very bottom) Latest Olive Oil Brand Tests by Consumerlab.com © 2016, David Leonard, Educational Program Coordinator (retired), Nutrition Connections Program, Univ. of NH Coop. Extension Good-quality extra virgin olive oil (EVO) has many well-researched health benefits (see my 1/15/16 post) such as blood pressure reduction and lower risk of heart disease, stroke, breast cancer, and cognitive decline. Benefits start with as little as 2 Tbsp. daily (about 40 cents for the lower-cost quality brands). www.consumerlab.com (a trusted testing company) recently analyzed 10 popular EVO brands it purchased at stores. Ratings are based on sensory qualities judged by a certified taster plus lab analyses for: Quality Purity (to detect adulteration with cheaper oils) Rancidity (due to improper handling which shortens storage life) Antioxidant content: Polyphenols are the ones behind EVO’s health benefits, and the amount varies with olive variety, amount of water during growth (low amounts boost polyphenols), and harvest stage (levels fall as olives mature). So a brand’s polyphenol content likely varies from year to year. Polyphenols increase bitterness which, along with pungency, determines robustnesss (boldness of flavor) graded as “mild”, “medium”, or “robust”. Brands Tested 365 Extra Virgin Olive Oil Bertolli Extra Virgin Olive Oil California Olive Ranch Colavita Extra Virgin Olive Oil Kirkland Signature (Costco) Organic Extra Virgin Olive Oil Lucini Premium Select Extra Virgin Olive Oil Newman’s Own Organics Organic Extra Virgin Olive Oil Pompeian Extra Virgin Olive Oil Spectrum Organic Extra Virgin Olive Oil Trader Joe’s Premium Extra Virgin Olive Oil Results All 10 brands claimed to be “extra virgin", but the taster downgraded 2 of them to “virgin” (Newman’s Own & Bertolli), and another was rated unsatisfactory (Pompeian). Both grades come from the first pressing of the olives w/o using solvents, other chemicals, or heat, but genuine EVO has a better taste and chemical makeup. 1. Top 3 choices Kirkland Signature Organic Extra Virgin Olive Oi l (Costco): Highest in polyphenols (369), good quality and taste, and one of the lowest priced. But the 2-liter bottle (over 2 quarts) may begin to spoil before it's used up (see below). Mild robustness. Trader Joe’s Premium Extra Virgin Olive Oil: Good quality & taste, relatively low cost. Polyphenol content of 237 is still a good level). Medium robustness. California Olive Ranch: Widely available (incl. Walmart). Good quality & taste. Three bottle sizes: 500 ml (16.9 oz.), 750 ml (25.4 oz.), 1.4 liters (47.3 oz.). Good polyphenol content (260). Mild robustness. Runner-up: 365 Extra Virgin Olive Oil. The lowest cost plus good taste & polyphenol content (216). Medium robustness. 2. Also approved but more pricey Colavita Extra Virgin Olive Oil Lucini Premium Select Extra Virgin Olive Oil Spectrum Organic Extra Virgin Olive Oil 3. Not approved Newman’s Own Organics Organic Extra Virgin Olive Oil: Taster-rated as “virgin” due to moderate taste defects. But good polyphenol content (330). Mild robustness. Pricey. Bertolli Extra Virgin Olive Oil: Passed lab tests, but rated as “virgin” (not extra virgin) on the taste test, so received an approval rating of “Uncertain”. Likely a mixture of good & lower-quality olive oils, but good polyphenol content (318). Mild robustness. Pompeian Extra Virgin Olive Oil: Taster-rated as “lampante” (unsatisfactory) despite being certified by the USDA and NAOOA (North. American Olive Oil Assoc.). Polyphenol content (218) was good, and it showed little rancidity. Mild robustness. Buying Tips Choose brands whose containers state the harvest date (ideally no older than last year’s) and that come in dark glass or plastic. The best California brands have a quality seal from the Calif. Olive Oil Council. Note that actual oil color can vary from green to pale yellow, but this isn’t related to quality. Storing EVO: Its shelf life unopened is about 18-24 months after bottling if protected from light & high temps (deterioration increases above about 700F). Once opened, significant loss of quality & antioxidants won’t occur if used within 30-60 days & kept tightly capped & away from bright light. You can also store EVO in the fridge, and any resulting cloudiness & minor solidification will resolve once it warms to room temps. https://www.oliveoiltimes.com is an excellent source for olive oil info and its health benefits.
