Ariston's Greek Extra Virgin Olive Oil (EVOO) is produced in the Messinia region of Greece by the Doukas family and local cooperatives. Made from Koroneiki olives which are naturally high in polyphenols! It is our flagship product that we have been importing to the U.S. market since 1997. (Available in bulk as Ariston item #110.) This oil boasts exceptionally low acidity levels (0.2-0.4%), resulting in a high-quality extra virgin olive oil with a smooth, well-rounded olive fruit flavor and a buttery finish, free from any acidic aftertaste. Each bottle contains 500 ml (16.9 oz). Ariston launched their Refill & Save Program in 1997. This listing is for the 5-liter size of Select Extra Virgin Olive Oil. Please note that the stainless steel container and empty bottles are sold separately. T
