What are Capers? Where Are They Grown?

Capers are the small, immature flower buds of the Capparis spinosa plant, a sprawling shrub native to the Mediterranean region. The buds are harvested and then either pickled or dried for culinary use. They have a strong, pungent flavor that can range from sour to salty depending on how they’ve been prepared and can be eaten raw or cooked in sauces or pastes.

Capers belong to the botanical family Capparaceae, which is an ancient group of mainly shrubby plants. The family includes over 100 genera and 2500 species of flowering plants that are distributed mainly in tropical, subtropical, and temperate regions. Within the Capparaceae family, capers are classified under the genus Capparis; though this genus also contains other edible fruit

Caper bushes grow in dry, sunny climates such as those found in southern Europe, northern Africa, and western Asia. In particular, it is believed that capers originated somewhere along the eastern coast of the Mediterranean Sea near the Syria – Israel – Lebanon- Turkey – Greece -Italy border region where wild caper plants still grow today. It is cultivated in other parts of the world such as California (USA) and India but most commercially grown capers come from Spain followed by Greece & Italy.

Brief History & Origin

Capers have a long history that dates back to ancient times. Archaeobotanical evidence of capers has been found in the Mediterranean region and Mesopotamia as early as the Upper Paleolithic period. The caper plant is believed to have originated in Central Asia, and the caper has been cultivated and used for culinary and medicinal purposes in the Mediterranean region for thousands of years.

Capers were used by the ancient Greeks and Romans, who prized them for their flavor and medicinal properties. During the Middle Ages, capers were widely used in European cuisine, and they played an important role in medicinal practices as well. Today, capers are still a popular ingredient in many Mediterranean dishes and are enjoyed around the world for their unique flavor and versatility.

Types of Capers and How They’re Harvested

Capers are available in various types that vary in size, color, and flavor. The different types of capers are commonly classified based on their size and region of origin.

The harvesting of capers is an artisanal process that requires patience and precision. Capers are handpicked in the early morning when the flower buds are still closed. The capers must be picked just before the bloom opens to ensure optimal flavor and texture. The process of harvesting capers is labor-intensive and can take several days to complete.

After the capers are picked, they are soaked in a brine solution to enhance their flavor and preserve their freshness. The brine solution typically consists of water, vinegar, and salt, and the capers are left to soak for several days to a few weeks. Once they are cured, the capers are ready to be used in various recipes.

What Are the Different Varieties of Capers?

The most common type of caper is the Capparis Spinosa variety, which originated from the Mediterranean region and is now grown around the world. This variety comes in two sizes: non-pareil (the smallest) and surfine (slightly larger). Non-pareil capers are usually sold in jars either pre-soaked or packed in brine; while surfines require soaking before use.

Another species of caper is Capparis Ovata, which is found mainly in Pakistan. These ones come with an orange hue on their outer layer and have a milder taste than the Spinosa type. When processed for consumption, they’re soaked overnight to reduce their bitterness before being seasoned with garlic or oregano for extra flavor; they can also be added directly to salads or cooked as part of certain dishes like risotto Milanese or pasta alla puttanesca.

A third variety is Capparis Cynophallophora—popularly known as “Budapest style” capers—which can only be found growing wild in certain parts of Hungary near Lake Balaton. It has grayish-green leaves with white spots on them and produces yellowish buds at maturity that taste similar to acidic olives when consumed raw but less so when pickled properly.

One final type called sea grapes grows mainly near beaches along coastal areas throughout Europe and North Africa; it has grape-like clusters instead of individual flower buds attached to its green stems and tastes sweet yet slightly salty once pickled together with vinegar or other seasonings.

Can Capers Be Grown at Home?

Yes, capers can be grown at home under the right conditions. Capers require a warm and dry climate with well-drained soil. They are native to the Mediterranean region and can be grown in USDA hardiness zones 9-11. Capers grow as a shrub and can reach up to three feet tall. They require full sun exposure and prefer slightly alkaline soil. However, growing capers at home can be challenging since they take several years to mature and produce buds. It is recommended to start with a young plant rather than planting from seed. With proper care and attention, capers can be successfully grown at home, providing a fresh source of this flavorful ingredient.

Capers vs. Caperberries

Capers and caperberries are two distinct ingredients that are derived from the same plant. Capers are the pickled unopened flower buds of the Capparis spinosa bush, while caperberries are the fruit that grows on the same bush. Capers are small in size and have a slightly pungent, salty flavor that can be used to add a tangy, acidic flavor to dishes.

In contrast, caperberries are larger than capers and have a milder and sweeter taste. They can be eaten whole, and their firm texture makes them ideal for use as a garnish or accompaniment to dishes like charcuterie boards or salads. While both capers and caperberries are used in Mediterranean cuisine, they differ in size, flavor, and texture, and thus can be used for different purposes in cooking.

Are Capers Olives?

No, capers are not olives. Capers are the unopened flower buds of the caper bush (Capparis spinosa), while olives are the fruit of the olive tree (Olea europaea). Although capers and olives are often used together in Mediterranean cuisine, they are two distinct ingredients with different flavors, textures, and nutritional profiles. Capers have a tangy, acidic taste and are often used as a garnish or to add flavor to savory dishes, while olives have a slightly salty, briny taste and can be used in a variety of dishes, including salads, sandwiches, and pasta sauces.

Are Capers Good For You? What Are its Health Benefits?

Yes, capers are considered to be healthy food that can offer a variety of health benefits. Here are some of the potential health benefits of capers:

  • High in antioxidants: Capers are rich in flavonoid compounds like rutin and quercetin, which have antioxidant properties. Antioxidants can help to protect the body against damage from free radicals, which are associated with chronic diseases like cancer, heart disease, and Alzheimer’s disease.
  • Anti-inflammatory: Capers have been found to have anti-inflammatory properties that may help to reduce inflammation in the body. Chronic inflammation is linked to many health problems, including arthritis, diabetes, and heart disease.
  • May improve digestion: Capers contain compounds that may help to improve digestion, including fiber and natural enzymes. These nutrients can help to promote bowel regularity and prevent constipation.
  • Low in calories: Capers are a low-calorie food that can be a good addition to a healthy diet. One tablespoon of capers contains just 2 calories, making them an ideal ingredient for those watching their weight.
  • Rich in vitamins and minerals: Capers are a good source of several important vitamins and minerals, including vitamin K, niacin, and copper. These nutrients are essential for maintaining healthy bones, promoting healthy skin and hair, and supporting the immune system.

Can People Have an Allergy to Capers?

Yes, people can have an allergy to capers. While caper allergy is not common, it is possible for some individuals to experience an allergic reaction after consuming capers. Capers are not considered a major allergen, but they may cause allergic reactions in people who are allergic to mustard oil or tree nuts. Symptoms of an allergic reaction to capers may include hives, itching, swelling of the face or mouth, difficulty breathing, and anaphylaxis.

People who suspect that they may be allergic to capers should consult with a healthcare professional for diagnosis and treatment. It’s worth noting that capers are often pickled in vinegar or brine, so they can be quite salty. It’s a good idea to rinse them before consuming them to remove excess salt.

Are Capers Vegetarian?

Yes, capers are vegetarian. Capers are the unopened flower buds of the caper bush (Capparis spinosa or Capparis inermis), and they are harvested by hand before they blossom. They are plant-based ingredients and do not involve the use of animal products. Capers are often used as a garnish or to add flavor to vegetarian dishes, such as salads, pasta dishes, and vegetable dishes.

What is Caper Butter?

Caper butter is a simple and delicious sauce made with capers and butter. It is a classic French sauce that is often served with fish or vegetables. To make caper butter, capers are sautéed in butter until they are fragrant and slightly crispy. The butter takes on the flavor of the capers and creates a rich and savory sauce that can be drizzled over fish or spooned onto vegetables. Some variations of caper butter include additional ingredients such as lemon juice, parsley, garlic, or shallots. Caper butter is easy to make and adds a burst of flavor to many dishes. It can also be used as a spread for bread or as a dip for vegetables.

How to Buy Good Quality Capers?

Firstly, you should look for capers that are packed in salt or vinegar. Both of these options can be good, but make sure that you choose capers that have been packed in high-quality salt or vinegar to ensure the best flavor. Secondly, smaller capers are generally considered to be of higher quality than larger ones. They tend to have a more delicate texture and a more intense flavor, so try to choose smaller capers when possible.

Thirdly, you should check the color of the capers. Good quality capers should be a dark green color, almost black. If the capers are too light in color, then this can be a sign that they are old or low quality. Lastly, you should read the labels carefully before buying capers. Make sure to check for any added preservatives or other ingredients. Look for capers that have no added ingredients or preservatives, as these will have the most natural and authentic flavor.

Capers can also be frozen for longer-term preservation. Rinse them in cold water and pat dry before placing them in a freezer-safe container. Cover them with brine and freeze for up to six months.


Pickling capers is a great way to preserve their freshness and add extra flavor to your dishes. Rinse them in cold water and pack them into a sterilized jar with spices of your choice.
