What is the difference between olive juice and olive brine?


Both olive juice and olive brine are made from olives, but they are used for different purposes in cooking and have some key differences. Olive juice is made by pressing or centrifuging olives to extract the liquid, while olive brine is the salty water left over from curing olives.

In this article, we’ll examine how olive juice and brine are made, their ingredients and nutritional values, how they taste, and how each is used in recipes. Understanding the distinctions between these two olive-based ingredients can help you determine when to use one versus the other in your cooking.

How Olive Juice is Made

Olive juice is made by pressing or centrifuging fresh olives to extract the liquid. This liquid is dominated by the juices from the olive flesh. Here is an overview of how it is made:

Olive Juice Production
  1. Olives are washed and any stems or leaves are removed.
  2. The olives are crushed or ground into an olive paste.
  3. The olive paste is pressed between mats or spun in a centrifuge to separate the liquids from the solids.
  4. The extracted liquid is filtered to remove any solid particles.
  5. The filtered olive juice is bottled for use in cooking or drinking.

This process extracts the watery juices within the olive flesh, resulting in a fluid product that is milder in flavor compared to olive brine.

How Olive Brine is Made

Olive brine starts its life as the curing liquid for olives. Here’s an overview:

Olive Brine Production
  1. Olives are soaked in water to remove any surface dirt.
  2. The olives are then drained and placed into a solution of salt water strong enough to cure them.
  3. Typically 8-12% salt is used. Other flavorings like vinegar, herbs, or oils may be added.
  4. The olives are cured in this brine for anywhere from a few weeks to over a year, depending on the type of olive.
  5. This long brining leads to strong salty and aromatic flavors permeating the olives.
  6. After curing, the leftover brine solution is bottled up for use in cooking.

So olive brine starts as the curing solution for olives, while olive juice is simply the pressed liquid from fresh olives. This leads to differences in their taste and saltiness.

Taste and Salt Content

Due to the different production methods, olive juice and brine have distinct tastes and levels of saltiness:

Olive Juice Olive Brine
  • Has a mild, delicate flavor
  • Tastes like the liquid from fresh olives
  • Low sodium content
  • Typically less than 100mg per serving
  • Very salty and pungent in flavor
  • Can have other preserved flavors like vinegar
  • High sodium content due to brining
  • Around 600-800mg per serving

So olive juice will have a lighter, more subtle olive taste without much saltiness, while olive brine is packed with intense briny flavors from the curing process.

Nutritional Profile

Despite coming from the same fruit, olive juice and olive brine differ in their nutritional content:

Olive Juice Olive Brine
  • Rich in antioxidants like polyphenols
  • Contains healthy monounsaturated fats
  • Very low in sodium
  • Minimal calories
  • High acidity
  • Fewer polyphenols and fats
  • Very high in sodium
  • Higher calorie count
  • Lower acidity

Olive juice retains most of the beneficial compounds like antioxidants, healthy fats, and acids directly from the olives. Meanwhile, olive brine is diluted with water during curing which decreases its nutritional value but concentrates the sodium content.

Uses in Cooking

The different flavors and textures of olive juice and brine lend themselves to different culinary uses:

Olive Juice Olive Brine
  • Drinking straight as a beverage
  • Marinating vegetables like mushrooms
  • Light salad dressings and sauces
  • Adding mild olive flavor to dishes
  • Marinating meats
  • Strongly flavored sauces and braises
  • Bread dipping oils
  • Adding a briny olive punch

Olive juice works well lightly drizzled over dishes or in sauces where you want light olive essence. Olive brine is used to impart a sharper, salty olive taste to strongly flavored marinades, braises, and condiments.

Popular Uses for Each

Here are some of the most popular ways olive juice and brine are used:

Olive Juice Uses

  • Drinking straight – Many people enjoy sipping olive juice straight as a tangy, savory beverage.
  • Salad dressings – Whisked with oil and vinegar, olive juice makes well-balanced light vinaigrettes.
  • Pasta sauce ingredient – Olive juice blends well into vegetable or cheese sauces for pasta.
  • Risotto/pizza topping – Drizzled over risotto or on pizza, it provides subtle olive flavor.

Olive Brine Uses

  • Marinated chicken, fish, pork – Great for robust marinades that impart olive flavor.
  • Stews and braises – Adds savory depth of flavor to long-cooked meat or bean dishes.
  • Dipping oils – Mixed with olive oil and herbs/spices, it makes a tasty bread dip.
  • Spaghetti sauce – A small amount can add richness and brininess to tomato-based pasta sauce.

As you can see, each liquid shines in different applications based on their concentration and salt content.


In a pinch, olive juice and brine can be substituted for one another in recipes, though they will provide different results:

Substitute Results
Olive juice instead of brine Will lose the strong salty flavor. The dish may need extra seasoning or salt.
Olive brine instead of juice Will significantly increase the saltiness. Use smaller amounts of brine.

To better mimic the flavor of the original ingredient, you can dilute brine with water to make it less salty, or add a pinch of salt to olive juice. But the overall flavor profile won’t be quite the same.

Storing Olive Juice and Brine

To maintain freshness after opening, olive juice and brine should be stored:

  • In the refrigerator
  • In a tightly sealed container
  • Away from light exposure

Properly stored and unopened, both products can last 1-2 years. Once opened, they should be used within a few months. Signs they may have gone off are mold, fouled smell, or very cloudy appearance.

Buying Quality Products

To end up with the best quality olive juice and brine:

  • Check for reputable producers and brands
  • Avoid additives like preservatives
  • Seek out expiry dates furthest in the future
  • Look for opaque, light-blocking bottles

Higher price doesn’t always mean higher quality. Smaller boutique producers may offer excellent products for less than major brands. Pay close attention to production methods and ingredients when choosing.


While olive juice and olive brine both start from the olive fruit, their different production methods result in very distinct tastes and uses. Olive juice showcases the fresh, delicate flavors of the olive, while brine is dominated by intense salty and aromatic qualities from curing.

Understanding when you want a subtle olive essence versus a potent briny punch will guide you in when to reach for the juice versus the brine. Taking the time to buy high quality, pure versions of each without unwanted additives will also pay off in better flavor.

Both olive juice and brine can be used creatively in a wide variety of Mediterranean and Middle Eastern inspired dishes. Keep them on hand to add delicious dimensions of olive taste easily at a moment’s notice.
