Olives: Storing After Opening

Ever wonder why your olives go soft after a few days? Let’s sort out the basics of keeping them fresh.

At a Glance

Fresh olives are naturally bitter, so they’re brined before we eat them. Green ones stay firm and sharp, while black olives are milder and can vary in texture.

Why Raw Olives Are Bitter

A fresh olive contains oleuropein, a bitter compound that protects the fruit on the tree. Soining pulls that bitterness out slowly, either by daily water changes, salty brine, dry salt, or a food-grade lye process.

Green vs Black Olives

Green and black olives come from the same tree; colour mainly reflects ripeness. Green olives are picked early and stay firm and sharp. Black olives that ripen on the branch become rich and fruity. The jet-black tins are actually green olives treated with lye and air, then fixed with a harmless iron salt, giving a milder taste.

Salt and Blood Pressure

If you’re watching sodium, note that a hundred grams of brined green olives can hold about 1,500 mg of sodium. That means ten medium green olives can deliver roughly a quarter of the WHO’s recommended daily salt limit. Tinned black olives tend to be a bit less salty, but they’re still salty.

Quick Fact

Ten olives can use up a quarter of your day's salt before dinner has started.

Choosing Olives at the Shop

When you shop, look for a clear brine that isn’t cloudy or frothy. Avoid cans or jars that are bulging, leaking, or dented. Pitted olives are convenient, but those with stones stay firmer. Some are stuffed with a red pepper paste, which adds flavor and a bit more salt.

Storing Olives After Opening

The brine is the olive’s bodyguard. Keep the olives submerged in their liquid and refrigerate. If the brine runs out, dissolve a teaspoon of salt in a cup of cooled boiled water, pour it over the olives, and use them within a week. Olives packed in oil need extra care; add fresh garlic or herbs only if you’ll finish them in four days.

Spotting Bad Olives

Check the surface for a thin white film; that’s usually harmless yeast you can skim off. If you see fuzzy spots in green, blue, black or pink, the whole jar should be tossed. Mushy or slimy olives are past their prime, and a sour, winey smell is normal, while a cheesy or nail-polish odor means they’re spoiled.

What Olives Do for You

Olives are a fatty fruit, mostly monounsaturated oleic acid, the same healthy fat found in olive oil. Ten medium olives give about 40-60 kcal, a little fiber, vitamin E, and some iron in tinned black varieties. They also contain polyphenols, though soaking washes many of them out. So a handful adds flavor, good fat, and a modest nutrient boost, but it isn’t a shortcut to all the benefits of olive oil.

Olive Kachumber

Dice a cucumber, a tomato and half an onion. Toss in eight rinsed, sliced olives and two tablespoons of chopped coriander. Squeeze half a lemon over the mix, finish with black pepper and a pinch of roasted cumin. No extra salt needed, the olives bring enough.

Myths and Facts

A common myth says black olives grow on a different tree. In reality, green and black olives are the same fruit at different stages. Some black tins are simply green olives that have been darkened with air and a harmless iron salt.

Olives in Tradition

Olives hold a special place in many Muslim homes because they’re named in the Quran. Families often keep a jar of olives or olive oil out of respect as well as taste, and traditional Unani medicine talks more about the oil than the fruit. Respect the tradition, but still count the salt.

Watch Your Salt

If you have high blood pressure, heart failure, kidney disease, or need to limit fluids, treat olives as a salty food and ask your doctor how they fit into your daily sodium budget. Children under five should get only pitted, small pieces, and babies under one should avoid olives altogether because their kidneys aren’t ready.
