It's in the Milling

In 2004, Apollo Olive Oil become involved with Dr. Marco Mugelli, the president of the Tuscan Professional Olive Oil Tasters and head of a research group supported by the Florence
Chamber of Commerce. Dr. Mugelli is a leading spokesman in the movement to advocate a new quality designation for olive oil one that would qualify and quantify the positive characteristics of
Super Premium oils, and would therefore provide consumers with valuable information while avoiding the political factors and economic issues involved in the traditional use of the term
Super Premium in the global marketplace.

To avoid the confusion and lack of meaning of the term Super Premium, Saltonstall Estate uses the nomenclature Super Premium. This terminology was proposed by Dr. Marco Mugelli in 2007.
The larger machine harvesting California Olive Oil Ranches have not as yet adopted this termenology for fear of not being able to qualify for the higher grade.

After more than a decade of scientific research into the components of top quality Super Premium olive oils, and the factors influencing quality olive oil extraction, Dr. Mugelli invented
and designed a method of milling under vacuum, which dramatically improves the extraction of polyphenols and provides much more quality control over the entire milling process. This new
technology can produce excellent Super Premium olive oil with roughly triple the amounts of polyphenols, compared to conventional milling technologies. Only five such vacuum mills exist
in the world, and Apollo Olive Oil was privileged to obtain one in 2005.

Since obtaining our new vacuum milling system and employing Dr. Mugelli’s techniques, Apollo Olive Oil has produced batches with as much as 810 ppm of polyphenols. The chart below are
the polyphenols of 11 leading 2014 California olive oils,

The low ppm of the machine harvested oils should not indicate any defect in their products or milling procedures. Their products are excellent, However, It is imposible to obtine high
polyphenols with the type of trees, milling procedures, and harvesting procedures they must use to produce cheap oil. Polyphenols are only a small part the health benifits which olive oil
provides. With machine harvest it is possible to produce an excellant oil for half the price. Only with machine harvest can olive oil be available to the mass

In 2005 Staltontall Estate conducted extensive reserch to quantify Oleocanthal in our oils, other California artisan oils as well as off the shelf imports. We were successful in locating the remarcable polyphenols in our oils and some other California olis but not in off the shelf imports.

More experimentation will solidify our understanding of the dynamics involved, but it is safe to say that our Olive Oil is at the forefront of polyphenol extraction, and may be the healthiest olive oil you can find.

Olive oil polyphenols have been the recent subject of several encouraging scientific studies – several of which are cited here:

Alpha-Tocopherol, the main tocopherol homologue found in olive oil, was determined in 90 Greek virgin olive oils. … Storage of samples under domestic conditions showed that good handling is quite important for retaining high alpha-tocopherol levels and for increasing, thus, the storage life and nutritional value.
