Is it true that black olives are simply ripe green olives? Do Kalamata olives only grow in the Kalamata region, and do olives naturally taste salty? Are olives actually fruit or vegetables?
Many myths have developed around this popular stone fruit. We’re clearing up the most common misconceptions.
Myth: “Black olives are simply ripe green olives.”
Sometimes – but not always.
Many olive varieties change color as they ripen, from green to violet and eventually black. Naturally ripened black olives develop a milder, fruitier flavor.
However, not every black olive is naturally ripened: some are harvested while still green and then artificially darkened. A look at the ingredients list can help – iron(II) gluconate (E579) or iron(II) lactate (E585) indicate that the olives have been darkened after harvesting.
Color alone does not reveal how a black olive came to be.
You can find out how to tell whether black olives have been artificially colored and how natural ripening works in detail in another article in our Olive Knowledge section.
At MANI Bläuel, olives are allowed to retain their natural character: differences in color and shape are not a flaw, but a sign of genuine organic quality. Our olives are harvested gently, naturally fermented in brine, and processed without artificial coloring.
Myth: “All Kalamata olives come from Kalamata.”
Not everything called Kalamata necessarily comes from Kalamata. This is where many people stumble over a small but important distinction: variety and origin are not the same thing.
The Kalamata olive is primarily an olive variety – not exclusively a designation of origin.
It originally comes from Messenia in the Peloponnese. Today, however, it is also cultivated in other regions such as Laconia.
Its characteristic properties – the dark color, firm skin, and spicy-fruity flavor – are determined by the variety and traditional processing, not solely by the region where the olives are grown.
Not every Kalamata olive comes from Kalamata – the name primarily refers to the variety.
Myth: “Olives are naturally salty.”
In fact, fresh olives contain very little salt. Straight from the tree, they actually taste extremely bitter and are therefore not immediately edible.
So where does that pleasantly salty taste come from – and what happens to the natural bitterness?
The bitterness is caused by the natural bitter compound oleuropein. It is only through further processing that olives are de-bittered and develop their characteristic flavor.
In traditional fermentation, olives are placed in brine for several months. During this time, the bitter compounds are gradually broken down while the characteristic flavor develops: the olives become milder, their texture becomes softer, and they absorb some of the salt from the brine.
At MANI Bläuel, we rely on this traditional, natural fermentation process. Our organic olives mature for several months in sea-salt brine – without chemical de-bittering – and are then prepared differently depending on the recipe. This results in olives of raw food quality that preserve their natural flavor and are characterized by craftsmanship, experience, and gentle processing.
So olives are not naturally salty – they only acquire their characteristic flavor during the course of further processing.
Myth: “Olives are vegetables.”
Although olives are often used in savory dishes such as salads, antipasti, or on pizza, botanically they are not vegetables.
Olives are fruits – more precisely, stone fruits. They grow on the olive tree and develop from the flower of the plant. Just like cherries, plums, or peaches, they contain a hard pit inside that protects the plant’s seed.
The fact that olives are often not perceived as fruit is mainly due to their flavor: unlike sweet fruits, they contain very little sugar and taste bitter when fresh from the tree.
So olives are actually a fruit – while still being a popular ingredient in savory cuisine.
Our conclusion
Many myths surrounding olives arise because their natural characteristics are not always visible. Whether it’s color, flavor, or botanical classification – first impressions can be misleading.
Behind every olive is a process: from the variety and origin to the degree of ripeness and traditional processing. These factors determine the quality, flavor, and character of an olive.
At MANI Bläuel, this tradition of original processing is at the heart of what we do. Our organic olives are given time to ripen naturally and develop their flavor at their own pace – resulting in a product that showcases the unique characteristics of the olive in all its diversity.
