Delving into the Olive Universe
Sit tight, dear readers, as we steer into the swirling vortex that is the Olive Universe. These tiny drupes (yeah, you heard us right, they're not fruits, technically speaking) hold a special place in our hearts and our recipes, especially for the culinary enthusiasts among us. From Mediterranean cuisine, think Greece's olive-laden dishes, to the Middle Eastern Za'atar sprinkled with olive oil, olives are a global agricultural powerhouse, revered for their cultural significance and gastronomic traditions.
But let's address the olive-phant in the room. The confusion between black and green olives is as old as the debate on whether a tomato is a fruit or a vegetable. Not to leave you in suspense, the difference between black and green olives is not akin to the difference between red and green apples, it’s more like the difference between a green and yellow banana. Hold on to that thought as we will delve deeper into this olive-colored mystery in the next section.

Why Green Olives Turn Black
Are you intrigued about the transformation of olives from green to black? Good, because we're about to lift the veil on this olive metamorphosis. Here's the big reveal: green olives and black olives are often the same olives, just at different stages of maturity and/or processing. The color change from green to black can occur on the tree as the olive ripens, or it can occur during the fermentation process. Which is an important step. Raw olives are uneditable due to oleuropein, an extremely bitter substance. The fermenting process, also known as curing, not only alters the olive's hue but also impacts its taste profile and nutritional changes.
It's like a caterpillar's transformation into a butterfly, except it's an olive, and there are no wings involved. More like a kitchen chemistry experiment with a side of food preservation, making each bite of an olive an exciting journey of flavors, from bitter to savory.

Freda Ehmann, The Mother of California Ripe Olives
Alright, let's set the scene. Picture the United States in the ’80s and ’90s. It was a time when chart-topping pop songs could be heard from every car radio, and our biggest concerns were largely confined to the schoolyard. If you were growing up in this era, chances are, you only knew one type of olive: The California Ripe Olive.
To understand the backstory of this ubiquitous pantry staple, we have to spotlight one incredible woman: Freda Ehmann. Affectionately known as the "Mother of California Ripe Olives," Ehmann was a business powerhouse who set out to revolutionize the olive industry.
Born in Germany in 1839, and later an immigrant to the United States, Ehmann waited until the age of 56 (1895) to make her mark - a comforting reminder that it's never too late to innovate. She developed a novel method that transformed unripe green olives into the delicious, black ripe ones we've all come to know and love, and aptly named them "California Ripe Olives."
In contrast to the traditional, and frankly slow, European methods that revolve around soaking olives in salt water for three to six months, Ehmann sought a faster route from tree to table. She introduced a process using lye that could cure olives in a remarkably short span of just seven days. Quite the upgrade, wouldn't you agree?
Interestingly, although Ehmann's method started with green olives, the end result was always dark black olives. It was as if the olives had a dramatic personality switch, from cheerful green to dark and moody black, much like a plot twist in a movie. It wasn't until later that it was found out that the culprit was oxygen sneaking into the lye soak, causing the olives to oxidize.
With this newfound knowledge, a more controlled process was introduced, one that could keep the oxygen out and let the olives retain their original vibrant green color.
So, there's your fun fact for the day. The difference between green and black California Ripe Olives is simply a matter of oxygen exposure during the curing process. The same olive, plucked from the same tree on the same day, could end up in a can of green olives or a can of black olives depending on what curing vat it ended up soaking in.
Old World Black Olives vs Green Olives
We've established that California Ripe Olives are plucked from the tree when they're still sporting their youthful green attire. But what about those olives that are treated with a nod to yesteryear, basking leisurely in brine? How do we get both green and black olives from that process?
The secret lies in the timing of the harvest. Black brined olives enjoyed a longer sunbathing session on the tree, ripening to their mature state, while the green ones were invited to the harvest party a little earlier. Like in California, green and black olives grow on the same tree even. It is when these olives are plucked that determines their final couture color.
Curious to know a little trade secret to distinguish between black lye-cured olives and black brine-cured olives? Keep an eye out for the subtle purple undertones. Black brine-cured olives tend to boast a hint of purple, creating a contrast to the sleek, jet-black look of the lye-cured variety. The more you know, right?
