A Different Origin Story
For centuries, the world's most celebrated caviars have come from the rivers and seas of the Northern Hemisphere. Names like the Caspian and Black Sea have become synonymous with the delicacy, shaping both tradition and expectation. Polanco Caviar begins somewhere entirely different.
In the heart of Uruguay, the Río Negro flows across a landscape known for its fertile soil, clean air, and pristine waters. Originating in southern Brazil before crossing the country and joining the Uruguay River, it is one of South America's great waterways. Its cool winters, temperate summers, and constant flow create an environment uniquely suited to sturgeon.
More than two decades ago, Estuario del Plata recognized the potential of these waters and established a farm unlike any other in the world. Today, Polanco produces the only sturgeon caviar harvested in the Southern Hemisphere, demonstrating that extraordinary caviar is not defined by geography alone, but by the conditions in which it is raised and the care with which it is crafted.
What began as an ambitious vision has become one of the most respected caviar operations in the world, supplying chefs, luxury retailers, and discerning enthusiasts across more than thirty countries.
The Río Negro Difference
Every exceptional caviar begins with exceptional water.
The Río Negro offers a rare combination of purity, movement, and seasonal variation. Its waters remain cool throughout much of the year while maintaining the oxygen-rich conditions necessary for healthy sturgeon development.
Unlike many aquaculture operations that rely on artificial recirculation systems, Estuario del Plata raises its sturgeon in floating cages positioned within the river itself. Constant currents, natural temperature changes, and the surrounding ecosystem allow the fish to develop in conditions that closely resemble their native habitat.
This approach is often described as "wild raised"—not because the fish are wild, but because they mature within the natural rhythms of the river rather than a fully controlled environment.
The result is a caviar with remarkable purity, balance, and complexity—one that reflects the environment from which it comes
A Commitment to Natural Feeding
The character of great caviar is shaped long before harvest.
At Estuario del Plata, feed is produced on-site using carefully selected regional ingredients and formulations developed specifically for each stage of the sturgeon's life cycle. By maintaining complete control over nutrition, the farm ensures consistency while preserving the natural quality of the fish.
This philosophy of stewardship extends throughout the entire operation. Every detail is monitored, every stage is carefully managed, and every decision is made with the goal of producing caviar that expresses the unique qualities of its origin.
The result is a product that is as authentic as it is refined.
Harvested at Peak Maturity
Patience is one of the most important ingredients in caviar production.
Polanco caviar is harvested during the austral winter, when the roe reaches its peak maturity and flavor development. Because Uruguay's seasons are opposite those of Europe and North America, Polanco's harvest takes place when much of the Northern Hemisphere is entering summer.
This unique timing provides access to exceptionally fresh caviar during a period when many traditional producers are outside their primary harvest season.
Each female sturgeon is individually evaluated using ultrasound technology to determine the precise moment of maturity. Only when the roe has reached optimal development is it selected for harvest.
This meticulous process ensures consistency while preserving the delicate texture and complex flavor that define premium caviar.
The Art of Malossol
The finest caviar in the world is never overpowered by salt.
Polanco follows the traditional Malossol method, a Russian term meaning "little salt." Considered the benchmark of premium caviar production, this technique uses only the minimum amount of salt necessary to preserve the roe while allowing its natural flavor to remain the focus.
Malossol requires precision. Too much salt masks flavor and diminishes nuance. Too little can compromise texture and stability. The balance is achieved through expertise, experience, and constant attention.
This delicate salting process allows the true character of the caviar to emerge: subtle marine notes, layers of butter and cream, delicate nuttiness, and a long, elegant finish.
Rather than tasting primarily of salt, Polanco tastes unmistakably of sturgeon, water, and time.
Salt from the Andes
Even the salt has a story.
For its Oscietra Grand Reserve, Polanco uses fossilized mine salt sourced from the Andes Mountains. Protected within ancient geological formations for millions of years, this mineral-rich salt is valued for its purity and consistency.
Its role is not to dominate the flavor of the caviar but to enhance it.
Like a chef selecting a finishing salt or a winemaker choosing a specific vineyard, Polanco's choice of salt contributes to the final expression of the product. It preserves the delicate texture of the roe while allowing the natural buttery and nutty characteristics of the caviar to shine through.
It is one more example of how extraordinary ingredients create extraordinary results.
Patience in the Tin
The journey from harvest to table does not end when the roe is salted.
After processing, Polanco caviar is matured in traditional 1.7-kilogram mother tins, where flavor and texture continue to evolve.
The Siberian Reserve spends between two and four months maturing before release. During this period, the caviar develops its signature notes of butter, cream, and walnut while maintaining remarkable freshness and balance.
Oscietra Grand Reserve undergoes an even longer maturation period, often between two and eight months. This extended aging allows its larger pearls to develop exceptional depth and complexity while preserving their elegant texture.
Like a fine cheese or an exceptional wine, great caviar benefits from time.

The Town Behind the Name
Polanco Caviar takes its name from San Gregorio de Polanco, a small riverside community on the northern bank of the Río Negro.
Home to just over 3,000 residents, the town has long been connected to the river and the abundance it provides. Local legend tells of indigenous communities that settled along these shores centuries ago, drawn by the plentiful fish found in the waters they called Hum—their name for the Río Negro.
Fishing remains woven into the culture and identity of the region.
By carrying the name Polanco, the caviar honors not only a place, but a history of craftsmanship, respect for nature, and a deep connection to the river that made it all possible.
Two Distinct Expressions of Polanco
Siberian Reserve
As pleasing to the eyes as it is to the palate, Polanco Siberian Reserve offers varied shades ranging from silver-gray to deep charcoal.
Produced from Acipenser baerii, its medium-sized pearls deliver a soft, silky texture with subtle marine character, gentle sweetness, and a smooth buttery finish. Notes of cream and walnut emerge gradually, creating a caviar that is both approachable and remarkably sophisticated.
Matured for two to four months in original tins, Siberian Reserve is celebrated for its balance, elegance, and lingering complexity.
Oscietra Grand Reserve
Oscietra Grand Reserve represents a more refined and luxurious expression of sturgeon caviar.
Its medium-to-large pearls display beautiful bronze and golden highlights while delivering a creamy texture with a distinctive pop. Rich buttery flavors unfold into delicate nutty notes, followed by a remarkably long finish that continues to develop across the palate.
Produced from Acipenser gueldenstaedtii and matured for up to eight months, Oscietra Grand Reserve is prized by chefs and caviar enthusiasts for its depth, complexity, and extraordinary balance.
