Due to printer minimums, smaller producers are forced to purchase more than a year’s worth of labels at a time.Also changing the copy on your labels every year incurs additional design and set-up costs.Additionally, because most of its heartwood has been lost, radioisotopes can't be used to give a more precise age.
Though an exact age of the tree cannot be determined, tree ring analysis demonstrates that it's at least 2,000 years old.

The Council’s Extra Virgin Seal Certification Program was established to guarantee that oil bearing the seal was of extra virgin quality.
