Why do green olives come in jars and black olives come in cans?
<|assistant|>
It is largely due to the process of how the olives are picked and harvested. Olives that are picked early while still green and immature have a higher chance of being accepted for the commercial market and thus require a jar to preserve the flavor. Black olives, on the other hand, are picked much later in the olive's life when they are ripe and dark in color and have a much stronger flavor. Due to their greater maturity, these darker olives require the tougher packaging of a can for shelf-life and preservation.
