Table olives: green, black, brined, and seasoned – what are the differences?

Green or black? In brine or seasoned? When choosing a jar of table olives, color is just one piece of information to consider. Stage of ripeness, cultivar, processing method, covering liquid, and any added ingredients also matter.

Understanding these differences helps you make a more informed choice, especially when comparing two seemingly similar products. In this PUGGHIA guide, we will look at what distinguishes green, turning, and black olives, what “in brine” really means, what changes with seasoned olives, and what information to check on the label.

Table olives are receiving increasing attention even at events dedicated to olive culture. The program for the tenth edition of the Vieste Oil Week, August 23–27, 2026, includes a session specifically dedicated to table olives on August 25, featuring in-depth analysis and tastings of the winning olives from the Ercole Olivario Competition. However, the topic goes far beyond a single event: knowing the different processing methods is useful every time we choose an olive to bring to the table.

What are table olives

Table olives are fruit from the olive tree intended for human consumption after appropriate preparation or processing.

The international Codex Alimentarius standard for table olives refers to healthy fruit from the cultivated olive tree, Olea europaea L., chosen in varieties suitable for processing and subjected to treatments that make them fit for consumption.

This means that not all olives are necessarily destined for the same use. Some cultivars have characteristics particularly prized for table consumption, others are used mainly for oil production, and some may have a dual-purpose character.

For table olives, characteristics such as fruit size, pulp-to-pit ratio, texture, shape, ease of pitting, and behavior during processing can be important.

It is also important not to confuse two different concepts: the cultivar identifies the variety of the olive tree, while terms like green, turning, or black classify the fruit mainly in relation to the stage of ripeness at harvest.

Why freshly picked olives are bitter

An olive freshly picked from the tree can have a very intense bitterness. Among the compounds naturally present in the fruit is oleuropein, a substance associated with the characteristic bitter taste.

The International Olive Council explains that, precisely because of these characteristics, olives are not normally eaten directly from the tree. There are some exceptions related to specific cultivars and conditions, but in most cases, processing is required to reduce or transform the natural bitterness.

However, there is no single method that works for all olives. The process can change depending on the cultivar, the degree of ripeness, and the type of product to be obtained.

Green, turning, and black olives: what changes

International classification distinguishes three fundamental categories in relation to the stage of ripeness: green olives, turning olives, and black olives.

Green olives

According to the International Olive Council's classification, green olives are harvested during the ripening period, after reaching normal size but before the color change begins.

The term “green,” therefore, does not automatically identify a specific cultivar. It describes primarily the stage of the fruit at the time of harvest.

Turning olives

Turning olives are harvested when the color change has already begun, but before full ripeness.

During this phase, the coloration can evolve from green towards pink, purplish, or brown shades, with differences linked to the cultivar and the degree of ripeness.

Black olives

In the official classification, black olives are fruit harvested when they have reached full ripeness or shortly before.

However, it is important to know that the market also includes preparations called darkened olives produced by oxidation. In this case, initially green or turning olives are subjected to a technological process that produces a dark color.

For this reason, the visible color alone does not allow you to reconstruct the product's history with certainty. To understand what you are buying, you must read the product name and information on the label.

Do green and black mean different varieties?

No, not necessarily.

“Green,” “turning,” and “black” are not cultivar names: they describe categories related to ripening and, in the case of some commercial preparations, to processing.

Consequently, you cannot conclude from color alone that two olives belong to different varieties. A cultivar suitable for multiple preparations can be used at different stages of ripeness, but this depends on the variety's characteristics and the chosen production process.

Are table olives and oil olives the same thing?

They all come from the olive tree, but their production destination may differ.

Some cultivars are valued primarily for table consumption, others mainly for oil extraction. There are also dual-purpose cultivars that can be used both as table olives and for oil production.

For olives destined for the table, the fruit's physical and technological characteristics are considered, including:

• size;
• shape;
• pulp-to-pit ratio;
• flesh texture;
• ease of pitting;
• behavior during processing.

Therefore, it is not correct to rigidly divide olive growing into “edible olives” and “oil olives”: the destination depends on the cultivar and the fruit's characteristics.

How table olives are processed

Before reaching the table, olives can be subjected to different processing systems. The goal is to reduce natural bitterness and obtain a product with characteristics suitable for consumption and storage.

International standards contemplate various preparations, including olives treated with alkaline solutions, natural olives kept in brine, dehydrated or shriveled olives, and olives darkened by oxidation.

Brine

Brine is a liquid medium consisting essentially of potable water and food-grade salts. Depending on the preparation, other permitted ingredients may be present.

It plays a role in processing and preserving the product, but do not think of it as an identical formula for every olive: the composition and management of the brine depend on the process used.

Fermentation

Brine and fermentation are not synonyms.

Brine is the liquid medium in which olives can be immersed; fermentation is instead a microbiological process that can be part of certain processing methods.

In some natural preparations, olives are placed directly in brine and may undergo partial or complete fermentation. Lactic acid bacteria and yeasts, among other microorganisms, can participate in these processes.

Duration, salt concentration, acidity, and other technological conditions are not universal and should not be automatically transferred from one product to another.

Other treatments

Systems recognized by technical sources also include:

• alkaline treatments used in debittering processes;
• natural processing in brine;
• dehydration or shriveling;
• use of salt in specific preparations;
• heat treatments when provided for by the process;
• darkening through oxidation.

The presence of different systems explains why two olives of the same color can have very different tastes, textures, and characteristics.

Brined olives and seasoned olives: what is the difference?

For those choosing between two packages, this is one of the most useful distinctions.

Brined olives

Brined olives are presented immersed in a saline covering liquid, used according to the characteristics of the specific production process.

This does not necessarily mean that every brined olive has undergone the same fermentation or processing. To know exactly what a package contains, you must always check the ingredient list and the producer's instructions.

Among PUGGHIA products, the Brined Olives 314g reference is available.

Seasoned olives

The term seasoned olives describes a preparation in which ingredients are added to the olives to characterize their taste.

Depending on the recipe, ingredients such as herbs, spices, garlic, chili, oil, or others may be used. There is no universal composition for seasoned olives: you must always check the individual package.

According to the product sheet currently published, the PUGGHIA Naturally Seasoned Olives 314g are seasoned with garlic, fennel seeds, hot chili pepper, and sunflower oil.

Which to choose?

There is no universally better category.

If you want to compare a more essential preparation with a more flavored one, the ingredient list is more useful than the trade name alone. A brined preparation with few added ingredients can be suitable for those who want to use the olive in different recipes; a seasoned olive can be convenient when looking for an already aromatic product to serve as an appetizer.

The choice therefore depends on personal taste and intended use.

Baresane olives

In local and commercial language, the expression Baresane olives is often encountered. To be precise, the Apulia PAT (Traditional Agri-Food Products) registers the “Térmite di Bitetto” table olive, also reporting local names such as Mela di Bitetto and Cima di Bitetto.

The area of origin indicated by the PAT is the province of Bari, particularly Bitetto and neighboring municipalities.

The Térmite di Bitetto is therefore a precise reference to the table olive heritage of the Bari area. It is preferable not to use “Baresana” as a generic definition for any olive produced in Apulia.

PUGGHIA has already dedicated a specific article to this topic. To learn more without duplicating its contents, you can read: Apulian Green Olives in Brine – Authentic Baresane.

In the shop, the Baresane Olives in Brine 1.4kg pack is also available, whose product sheet identifies the olives as Baresane, Térmite di Bitetto.

How to read olive labels

Two jars that look similar can have different ingredients and processing. That is why the label is essential.

Ingredients

Check which components are present in addition to the olives: water, salt, any acidity regulators, antioxidants, oil, herbs, spices, or other ingredients.

Type of covering liquid

If the olives are immersed in a liquid, check how it is described. The presence of brine alone does not allow you to establish the entire process the product has undergone.

Salt

If you want to compare the salt quantity of different products, refer to the nutritional declaration on the packaging and compare values referring to the same quantity of food.

Aromas, herbs, and spices

For seasoned olives, check which ingredients are actually used. Preparations sold under the same name can be very different.

Allergens

Always read the information on allergens and any indications related to cross-contamination provided by the producer.

Net weight and drained weight

When a solid food is presented in a liquid medium, European regulations require the indication of the drained net weight. This data allows you to understand how much solid matter is contained in the package.

Origin and provenance

Check the origin or provenance indications actually present on the label when declared or required by applicable law. Do not deduce the origin of the olives only from images, colors, or geographic references used on the packaging.

Storage after opening

The producer's instructions are essential: temperature, storage methods, and timelines after opening can vary based on formulation and process.

You can also delve deeper into the topic in the PUGGHIA article How to store oil, taralli, and preserves during the summer.

Net weight and drained weight

Net weight and drained weight do not indicate the same thing.

In the case of a solid food presented in a liquid medium, the net weight refers to the overall contents of the package, while the drained weight indicates the quantity of the solid part after separation from the covering liquid according to the prescribed methods.

To compare two packages of olives in brine, it is therefore useful to look at:

• net weight;
• drained weight;
• ingredients list;
• nutritional values;
• price of the package.

How to use olives in the kitchen

Table olives can be used both on their own and as an ingredient. The choice depends mainly on their flavor profile and level of saltiness.

Apulian aperitif

For a simple aperitif, you can pair olives, taralli, and a vegetable preserve. Before adding other seasonings, always taste the olives: a preparation that is already seasoned may be sufficiently salty and aromatic.

You can pair them with 400 g Apulian Homemade Taralli or with 400 g Apulian Fennel Taralli.

To learn more about taralli, you can also read the PUGGHIA deep dive dedicated to Apulian taralli.

Friselle

Tomato, olives, and extra virgin olive oil can complete a frisella with just a few ingredients. The amount of salt added should be adjusted by taking into account the saltiness of the olives.

You can use 400 g typical Apulian Frise and explore their history and characteristics in the article Apulian frise: history, ingredients, and tradition of an ancient bread.

Salads

Olives can complete vegetable, legume, or grain salads by adding saltiness and texture. If you choose seasoned olives, also consider the oil, spices, and herbs already present.

Bread and focaccia

Green or black olives can be used in bread, focaccia, and other baked goods. The choice does not depend on a universal rule, but on the recipe and the desired flavor profile.

Orecchiette and first courses

Sliced or pitted olives can accompany pasta sauces based on tomato, vegetables, or other ingredients. In this case, too, it is best to add salt only after evaluating the saltiness of the olives used.

How to taste a table olive

The International Olive Council has an official method for the sensory analysis of table olives, the COI/OT/MO No 1/Rev.3/2021.

This is a professional method intended for trained panels. Therefore, it is not correct to turn it into a simple, invented home tasting sheet.

The taste attributes considered by the method include:

• salty;
• bitter;
• acid.

For texture, the following are evaluated in particular:

• hardness;
• fibrousness;
• crunchiness.

The method also considers specific sensory defects recognizable by a trained panel.

At home, it is still possible to taste with greater attention: first observe the integrity of the fruit, smell it, and then focus on saltiness, acidity, bitterness, and texture. Visual observation at home is a practical check and should not be confused with the taste and tactile descriptors of the official IOC sheet.

How to store olives after opening

There is no universally valid number of days for all olives after opening. Processing methods, packaging, and formulations can differ.

As general rules of good home management:

• follow the conditions indicated on the label;
• refrigerate the product when indicated;
• keep the olives in their covering liquid when required by the instructions;
• remove the product using clean utensils;
• avoid contact with utensils already used for other foods;
• reseal the package well;
• do not consume the product if the package or content shows suspicious changes.

For PUGGHIA items, you must refer to the instructions on the specific package purchased, as they may differ from one product to another.

How to choose between green, black, brined, and seasoned olives

The easiest way to choose is to start with how you plan to use them and then check the label.

If you are looking for a preparation with few added aromatic elements, check for a brine with a simple ingredient list. If you prefer a product already characterized by aromas, herbs, or spices, you can look towards seasoned olives.

Between green or black olives, however, do not rely solely on color: cultivar, maturity, and processing can profoundly affect the final result.

PUGGHIA olives and products to pair

For an aperitif or a simple meal, you can combine olives with products that have complementary textures and tastes.

• 314 g Olives in Brine
• 314 g Naturally Seasoned Olives
• 1.4 kg Baresane Olives in Brine
• 212 g Black Olive Pâté
• 400 g Apulian Homemade Taralli
• 400 g Apulian Fennel Taralli
• 314 g Sun-dried Tomatoes in Oil
• 400 g Typical Apulian Frise
• 500 ml Extra Virgin Olive Oil

The principle is simple: there is no need to overload the table. Olives, taralli, a preserve, bread or frise, and a good oil can already make for a balanced and convivial aperitif.
