there are purple/black olives, they deepen in colour when processed in brine
- we pick our Frantoio when some of the olives have turned black and the
bulk of the tree is green or turning purple so I'm not sure where the
statement that there are no black olives comes from




> There is no such thing as Black Olives... Black Olives are treated or
> De-Bittered for eating- The Black color comes from the process. All Olives
