Oscietra classic is a fresh caviar that is low in salt, prepared exclusively with pure Russian sturgeon roe (acipenser gueldenstaedtii). True Oscietra caviar has historically been considered one of the most sought after foods in the world. It is a caviar of superb quality, able to satisfy the most demanding of palates. The caviar is gathered mainly in autumn and winter. The wide range of Russian sturgeon eggs have typically been classified into three different selections of caviar: Classic, Royal and Imperial. Oscietra classic has a good sized pearl (2.7 mm – 3.0 mm) and features a smooth, velvety texture, with characteristic bronze flecks. The colour ranges from dark grey to dark brown with warm amber nuances.
The flavour is delicious, balanced and complex, and its extraordinary quality should be savored in its purest form. It offers harmonious and extremely pleasant nutty notes (hazelnut), accompanied by a lingering aroma that brings to mind the scents and flavours of the sea (oyster). The term Oscietra (ossetra, oсетр, asetra, osetra and osciètre) refers exclusively to caviar prepared with roe from acipenser gueldenstaedtii or acipenser persicus (two similar species, both of which come from the Caspian Sea). Actually, it is often incorrectly described on labels in which other species of sturgeon are used that are in no way comparable to true Oscietra.
The sturgeon is average in size and can be as long as two meters, weighing more than 60 kilos. It is characterized by colouring that, at times, tends toward golden hues. It comes from the Black Sea, Caspian Sea and the Sea of Azov, heading up rivers like the Volga and Danube. In the spring waters of the Parco del Ticino (near Pavia), the youngest types take about 10-12 years to produce the first precious eggs.

Da Vinci is the name of caviar made from the roe of the Adriatic sturgeon (acipenser naccarii). This sturgeon, which was once abundant in Italian waters, used to be fished in spring when the fish would make their way up the major rivers of the Po Valley to reach the best areas for reproduction. This authentic Italian caviar was considered a true delicacy by the noble families of the Renaissance era (the Gonzaga, Este, Medici, and Sforza families). Ancient recipes for making this type of caviar date all the way back to the fifteenth century. The diameter of the roe is average in size, from 2.4 mm to 2.8 mm, and the shell is fragile, silky and delicate. It often has a wet texture with a fresh, characteristic taste.
Da Vinci is a caviar with a distinctive (wild) flavour. When freshly prepared, it is characterized by a nutty hazelnut aroma and by salty notes, while, later, the flavour is more strongly influenced by the sea. Roe are glossy and their colour features hues that range from intense black to brown. They are collected in the spring, and only come from Adriatic sturgeon, an Italian species typical of the Adriatic Sea and the main waterways of the Po Valley, Dalmatia and western Greece.
In the spring waters of the Parco del Ticino (near Pavia), the youngest types take about 11-14 years to produce the first precious roe.

The Ticino Valley Park in Lombardy, the first regional park in Italy, was founded in 1974 to protect the river and the natural environment from industrialization and urbanization. The Ticino Valley Nature Park – the river and its valley are a unique landscape of inimitable beauty and is the most extensive natural area of the Po Valley. This corner of unspoiled nature neighbors areas where human activity has left irreversible changes. Many springs, ancient agricultural irrigation systems, and majestic castles blend perfectly into the landscape and make the panorama extremely colorful.
The Ticino Valley is home to streams, coniferous forests, heathlands, marshes, all of which provide a favorable habitat for many species of animals and plants. The flora of the Ticino Park can be traced back to pre-human times. That is why as many as 48 species of mammals are at ease in the valley. Among them are martens, foxes, badgers, black squirrels and weasels, which coexist without disturbing the biological balance. The Ticino River has always been a natural boundary between civilizations, nations, peoples and rulers, and maybe that is why it has been preserved in pristine condition. Since 2002, the Ticino Valley has been one of the world’s biosphere reserves in a network recognized by UNESCO under the Man and the Biosphere Programme (MAB).
Biosphere reserves are terrestrial, coastal and marine ecosystems whose purpose is to support and demonstrate a balanced relationship between human populations, economic development and nature. The MAB World Network of Reserves, established in 1976, currently has 631 reserves in 119 countries. The prestigious MAB designation enhances the model of protection and development that both Ticino Parks (Lombard and Piedmont) already follow. This, in turn, attracts park managers, administrators and local communities to participate in the protection and promotion of these landscapes, so rich in historical and cultural values.

There are two main methods of caviar production: milking and traditional methods, each with its own characteristics and implications for product quality and safety.
Milking caviar is extracted by the milking method, which keeps the fish alive and can produce caviar an average of 6-8 more times. The process involves massaging the abdomen of the fish or using the “caesarean section” method, in which an abdominal incision is made to extract the eggs, after which surgical sutures are placed in the fish. During milking, injections of chemicals and hormones are often used to facilitate the separation of the eggs from the ovarian walls. These hormones help the eggs come out more easily and with less damage. However, the presence of hormones in fish and caviar poses the greater risk to human health, as they can affect the consumer’s hormones. Caviar quality can degrade with each milking session as the fish do not have time to fully recover their caviar reserves, making subsequent batches less mature and uniform.
Traditional caviar harvesting method is obtained by killing the fish and extracting the eggs from their abdominal cavity. This is a traditional method that allows precise control over when the caviar is harvested, ensuring its uniformity and high quality. This method is considered more consistent in quality, as the fish is killed at the exact moment of caviar maturation. This method guarantees a high quality product and a true gourmet flavor.
Caviar always contains salt, and the classic amount is 3%. The term “malosol” historically meant a salt content of no more than 5%, but this is no longer relevant today. Some producers reduce the salt content to 2-2.5%, which shortens the shelf life and requires a lower temperature. Caviar with 3% salt is stored at a temperature of 0 ° C – +4 ° C, while caviar with 2.5% salt requires a temperature of -2 ° C – 0 ° C, which is difficult to provide at home.
Also added to caviar is borax (sodium salt of boric acid), which is allowed in Europe and is a natural additive.
Pasteurization involves heating caviar to a certain temperature that kills microorganisms that can cause spoilage of the product to extend its shelf life, while retaining much of its flavor and textural characteristics.
The pasteurization process allows caviar to last longer without the need for preservatives. However, it can slightly alter the texture of the caviar, making it slightly denser and giving it a more intense character compared to fresh caviar.
Pasteurization is often used for caviar that is intended for export or long-term storage. Although pasteurized caviar may be less tender compared to fresh caviar, it remains a high quality product and is often preferred due to its long shelf life and stability of flavor.
Fresh black caviar is divided into several categories, each of which differs in quality, egg size and flavor characteristics.
Classic (or Prestige) caviar is the basic level of quality. The eggs are medium in size and have a rich flavor with notes of nuts and butter. This caviar is perfect for beginning gourmets who want to explore the world of black caviar.
Royal caviar represents a higher level of quality. It includes larger sized roe eggs that have a rich and creamy flavor. The color ranges from brown to dark brown and the taste is characterized by notes of pear, butter and hazelnut with a bright and refreshing aftertaste.
Imperial: This is the highest category of caviar. The roe eggs are the largest and hand-selected, making it the rarest and most valuable caviar. The taste is complex, balanced, with a rich nutty flavor and a long aftertaste. The color of the eggs varies from amber-brown to light gray with characteristic “tiger eyes”.
The higher the gradation, the more exquisite the flavor and texture.
We offer three types of unpasteurized (fresh) caviar of Russian Sturgeon, Adriatic Sturgeon and Sevruga: Classic, Royal and Imperial. Two types of unpasteurized caviar of Siberian and White Sturgeon are also available: Prestige and Royal. Beluga and Albino Sterlet caviar is available in one gradation – Royal.
Black caviar, both pasteurized and fresh, is graded by quality. Pasteurized caviar is heated to a high temperature and hermetically sealed in jars to increase its shelf life, but this can alter its taste and texture.
The main gradations of caviar are:
Grade A:
Quality: Highest quality caviar. The roe eggs are even, uniform in size and color, without damage. The texture is dense but delicate, with good flavor.
Description: This caviar meets all standards of high quality including color, size, aroma and texture. It has a clean flavor and attractive appearance.
Grade B:
Quality: Good quality, but with slight variations in size, shape or color of roe eggs. These are usually roe eggs with slight defects that do not affect their flavor.
Description: These eggs are also of high quality, but the roe eggs may be less even or slightly deformed. Its characteristics may vary from batch to batch. Nevertheless, it remains tasty and valuable, although not as expensive as Grade A.
All Ars Italica caviar comes exclusively from sturgeons raised in Ticino Park and is marked with the "Ticino Park – Controlled Production" and "Friend of the Sea – Sustainable Aquaculture Certification" labels. Ars Italica is an exclusive partner of Storione Ticino and is actively involved in projects to restore and protect local sturgeon populations.
We offer caviar from 7 sturgeon species
The Russian sturgeon, also known as the guildenstaedt sturgeon, received its scientific name in honor of the German naturalist Johann Anton Guildenstaedt, who studied the flora and fauna of Russia in the 18th century. The Russian sturgeon is one of the oldest fish species, its ancestors existed 200 million years ago. This species of sturgeon is one of the most famous and valuable.
The Russian sturgeon lives in the basins of the Black, Caspian and Azov Seas, as well as in the rivers flowing into these seas, such as the Volga and Don. It plays an important role in the ecosystems of these water bodies. In recent decades, the Russian sturgeon population has declined significantly due to overfishing and poaching. Programs to conserve and restore the Russian sturgeon population include releasing their fry into the natural habitat, which helps to increase the numbers of this rare fish. Thanks to conservation and captive breeding efforts, the situation has begun to improve, but the sturgeon is still threatened
The Russian sturgeon has an elongated body covered with bony scutes and a long nose equipped with barbels that help it find food at the bottom of a body of water. These fish prefer to feed on small fish, mollusks and crustaceans. They are solitary in saltwater, but become more social when they move to freshwater to spawn. In the wild, Russian sturgeon can migrate up to 1,000 kilometers to spawn, returning to the same places where they were born, making them vulnerable to changes in the environment. Sturgeons can live up to 50 years, reaching lengths of up to 2 meters and weights of over 60 kg. They do not reach maturity until they are 12-15 years old.
The Russian sturgeon continues to be a symbol of luxury and high quality. The difficult conditions of sturgeon farming and protection make them even more valuable and in demand on the world market.
The Siberian sturgeon (Acipenser baerii) inhabits numerous river systems in Siberia, such as the Ob, Yenisei, Lena and Kolyma rivers, which flow into the Kara, Laptev and East Siberian Seas. This species is also found in Kazakhstan and China, in the Irtysh River, a tributary of the Ob. It received its species name in honor of the German biologist Karl Ernst von Baer, who made a significant contribution to the study of the ichthyofauna of Russia.
The Siberian sturgeon is a medium-sized member of the sturgeon family, reaching an average length of 2 meters and a weight of about 65 kg. The maximum recorded weight of this fish was 210 kg. The Siberian sturgeon can live up to 60 years, which makes it a long-lived fish. Sexual maturity comes rather late: males reach it at the age of 11-24 years, and females at the age of 20-28 years. They spawn in rivers with strong currents, preferring stony or gravelly areas.
The diet of the Siberian sturgeon includes a variety of bottom-dwelling organisms such as crustaceans, chironomid larvae and other small invertebrates. Despite their size, sturgeons feed on relatively small and immobile prey.
In recent decades, the Siberian sturgeon population has declined dramatically due to habitat loss, degradation and poaching. About 40% of spawning areas have become inaccessible due to the construction of dams, and high levels of water pollution negatively affect the reproductive function of the fish. Therefore, the International Union for Conservation of Nature (IUCN) has included the Siberian sturgeon in the list of critically endangered species.
The Siberian sturgeon is actively bred in aquaculture for both meat and caviar production. Due to its ability to complete its life cycle in fresh water and its relatively early sexual maturation, the Siberian sturgeon has become a popular subject for captive breeding.
Thus, the Siberian sturgeon is an important species both ecologically and economically, requiring constant efforts to protect and restore its numbers.
The white sturgeon (Acipenser transmontanus) is the largest freshwater fish in North America. Found along the Pacific Coast from Alaska to California, this species is also found in river systems such as the Fraser River in British Columbia and the Columbia River in Washington and Oregon.
These fish prefer deep, slow-flowing waters with sandy or muddy bottoms. White sturgeon often seek refuge among submerged boulders or fallen trees where they find shelter and an abundance of food. Interestingly, white sturgeon sometimes exhibit a behavior known as “porpoising,” where they jump out of the water and come back in with a splash. The reasons for this behavior are not fully understood, but it is thought that this is a way for sturgeons to communicate with each other or to get rid of parasites.
White sturgeons can live for more than a hundred years, making them one of the longest-living fish. Some individuals reach a length of up to 6 meters and a weight of over 680 kg. On average, adults are between 2 and 3 meters long and weigh several hundred kilograms.
The white sturgeon is a predator and feeds on various wildlife. Young individuals eat insect larvae and small invertebrates, while adults prefer fish such as salmon, herring and flounder, as well as shrimp and mollusks.
White sturgeon reproduction is slow; they spawn every few years. Males reach sexual maturity by age 15, and females by age 20. During spawning, they migrate up rivers in search of fast-flowing areas with gravel bottoms. Females can lay between 400,000 and 4 million roe eggs at one time, which compensates for the rarity of their spawning.
Due to overfishing and habitat destruction, white sturgeon numbers have decreased significantly. This species is now protected by law, and active programs are underway to restore the population. White sturgeon play an important role in ecosystems, helping to maintain the balance of food chains and contributing to the recycling of organic matter.
The Adriatic sturgeon, also known as Acipenser naccarii, is an endemic species of the Adriatic Sea and its tributaries. These fish are of significant historical and ecological importance, inhabiting rivers such as the Po, Ticino and Adige, as well as the coastal waters of the Adriatic Sea. These fish can reach lengths of up to 2 meters and weights of up to 25 kg, although smaller individuals are commonly found. Adriatic sturgeons have an olive-brown back, light sides and white belly, making them easily recognizable.
One of the unique traits of the Adriatic sturgeon is its ability to adapt to different levels of salinity. Although these fish can live in saltwater, they prefer to spend most of their lives in freshwater and brackish waters such as estuaries and lower river reaches. Adriatic sturgeons feed on a variety of bottom-dwelling organisms, including small fish, crustaceans, and mollusks. Their diet may also include organic matter and small decomposing remains, emphasizing their role in ecosystems as opportunistic feeders.
This sturgeon species is considered critically endangered due to overfishing, habitat destruction, and water pollution. In recent years, significant efforts have been made to restore Adriatic sturgeon populations, including captive breeding programs and the release of fry into natural habitats.
The Adriatic sturgeon is an example of how anthropogenic changes can affect biodiversity and ecosystems. The conservation of this species is important not only for maintaining ecological balance, but also for the cultural heritage of the regions where it lives.
The stellate sturgeon or starry sturgeon inhabits the basins of the Black, Azov, Caspian and Aegean Seas. These fish prefer shallow areas with sandy or muddy bottoms, where they feed on small crustaceans, worms, plankton and small fish. A unique feature of the Sevruga is its long and thin straight nose, as well as five small barbels located closer to the mouth than to the tip of the nose. These features distinguish it from other sturgeons.
Sevruga is one of the smallest sturgeon fish. Adults reach a length of up to 220 cm and a weight of up to 80 kg. This species is much smaller than other sturgeon species such as beluga or Russian sturgeon. Despite its small size, the Sevruga plays an important role in the ecosystems where it lives.
Unfortunately, the Sevruga is in danger of extinction. Over the past three decades, its population has declined by more than 90% due to overfishing and habitat destruction. International trade in this species is restricted under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). As part of efforts to conserve Sevruga numbers, captive breeding programs and the release of juveniles into the natural habitat are being actively implemented.
This fish is anadromous, which means that it migrates up rivers to spawn. The dependence on freshwater for reproduction makes Sevruga particularly vulnerable to environmental changes. In addition to this, Sevruga meat is prized for its tenderness and versatility in cooking. It is used for kebabs, frying, baking and smoking. Sevruga caviar is known for its rich flavor and is one of the most expensive types of caviar, second only to beluga and Russian sturgeon caviar.
The albino sterlet (Acipenser ruthenus) is a rare and amazing representative of sturgeon fish living in freshwater basins of Eurasia. It originates from Central Asia and Eastern Europe, but is currently bred exclusively under commercial conditions. This species is suitable for keeping in large ponds, as it reaches a considerable size, up to 1.2 meters in length and a weight of up to 4 kg.
The albino sterlet is distinguished by its bright white color, sometimes with a yellowish tint, and pink eyes, which is the result of albinism. These fish have an elongated, spindle-shaped body with a long, pointed nose and a pair of barbels near the mouth, giving them a primitive and unique appearance.
These fish prefer cold, well-aerated water and can tolerate temperatures as low as 10 °C. In their natural habitat, sterlet live exclusively in fresh water, only occasionally occurring in brackish waters. The main habitats are rivers flowing into the Black, Azov and Caspian Seas, as well as the Danube and Isar rivers, where the species has been successfully reintroduced.
The albino sterlet feeds on bottom-dwelling organisms such as worms, crustaceans, insect larvae, snails and small fish. It actively feeds on soft or muddy bottoms where it can be observed searching for food. These fish prefer slow feeding from the bottom, so a special food that sinks is suitable for them.
In commercial breeding, albino sterlets are popular among aquarists and pond owners due to their bright coloration and interesting behavior. They can be tamed for hand feeding, making them even more attractive for keeping in ornamental ponds. Albino sterlet requires a pond with a volume of at least 10 cubic meters of water and a depth of more than 1.5 meters to provide comfortable conditions for life and growth.
The beluga (Huso huso), also known as beluga sturgeon, is the largest freshwater fish in the world. It lives in the basins of the Caspian and Black Seas, as well as in rivers flowing into these seas, such as the Volga and Danube. In the past, belugas were also found in the Adriatic Sea and in the rivers connecting these water bodies.
Belugas can reach incredible sizes. The largest individuals can grow up to 7 meters in length and weigh more than 1500 kg. On average, adult belugas reach a length of 2 to 3 meters and a weight of 100 to 300 kg. Belugas have a unique physical structure: their elongated body, cylindrical shape and cartilaginous skeleton which makes them ideal inhabitants of aquatic environments.
The beluga is a predator that feeds primarily on fish. Young individuals feed on small invertebrates, but as they mature, their diet includes larger fish such as herring, flounder, and various carp species. Beluga can also migrate long distances to spawn in freshwater. These migrations can reach hundreds of kilometers, and the fish must overcome numerous obstacles to reach their spawning grounds.
Beluga is an anadromous fish, which means that it migrates from saltwater to freshwater to spawn. During spawning, female belugas can lay up to several million roe eggs, ensuring the continuation of the species. However, due to the long period of sexual maturation, which occurs at the age of 12-16 years for males and 16-22 years for females, and the low frequency of spawning (once every 4-7 years), beluga population is under threat.
The main threats to beluga are overfishing and destruction of natural habitats. Beluga caviar, known as the most expensive caviar in the world, makes the fish a target for poachers. In addition to this, the construction of dams and pollution of water bodies have made it much more difficult for beluga to reproduce naturally.
Thus, beluga is not only a symbol of majesty and power, but also an example of the importance of biodiversity conservation and protection of rare species.
