The Untold Story of How Black Olives are Made

FAQ

What do they soak olives in to make them black?

The color difference between green and black olives is due to the curing process, not ripeness. Green olives are harvested before ripening and cured using methods like lye or brine soaking. Black olives are often riper at harvest or turn black during fermentation and oxidation in brine.

Are black olives healthier?

The nutritional content of black and green olives are very similar — both contain healthy fats, vitamin E, and other antioxidants. However, there are some key differences, the major being their color and the ripeness when picked. Black olives are ripe when harvested, while green olives are unripe.

Why are black olives always in a can?

The end product is raw, cured and crisp, olives. The short of it is — black olives are “always” in a can because the canning process is what creates the desired sweetness; and green olives are “always” in a jar because the final product is expected to be a crispy raw olive, not a cooked one.

What is a black olive?

Black olives are olives that have been allowed to fully ripen on the tree before harvesting. There are many different varieties based in part on geographic origin and tree species, but also influenced through storage and curing techniques. Nearly any ripe olive is considered “black,” even if its true color is more reddish or purple.

Which olive is healthier, black or green?

Green olives have a lot of vitamin E, but they also have a lot of sodium. People who are worried about their sodium intake should eat black olives instead. However, the servings must be limited.

Why do black olives turn black?

For many manufacturers, this is a reason to take them unripe from the tree and color them artificially later. Iron (II) gluconate and iron (II) lactate are the additives used for dyeing. The iron salts turn the actually green olive black. Are Black Olives Carcinogenic?

Where are black olives grown?

California, alongside Greece, Spain, and the southern coasts of Italy and France, are some of the world’s largest producers of black olives. Greek-grown Kalamata olives are some of the most commonly sold, alongside California Mission olives.
