What is "arbosana"

The Arbosana is an olive cultivar from Spain. Typically used for olive oil production, Arbosana thrives in super-high density growing systems. In 2009, a study by UC Davis found that 16% of super-high density olive groves (1,687 acres) in the state were Arbosana, and that along with Arbequina and Koroneiki, Arbosana olives were among the most common in the state.
