Tipos de Caviar

Authentic caviar is one of the most exclusive treasures in world gastronomy and comes solely from the roe of the sturgeon (Acipenseridae family), featuring legendary varieties such as Beluga, Osetra, and Sevruga. At the pinnacle of rarity, we find Sterlet sturgeon caviar, a gem so scarce that its price places it only within reach of the most privileged palates. Currently, wild sturgeon is a protected species under the CITES convention; the most significant population resides in the Caspian Sea, where Russia and Iran lead the production of 85% of today's traditional caviar of wild origin.

It is essential to distinguish the genuine product: any other processed roe must legally specify the fish of origin, such as "salmon caviar" or "lumpfish caviar." In international labeling, if the packaging only displays the term "caviar", it is guaranteed by law to come from sturgeon.

Caviar Grading and Evaluation

The excellence of caviar is determined by three key factors: the diameter of the roe, its hue, and the artisanal production method. Traditionally, a scale of zeros is used to classify color: 000 designates the lightest, pearlescent caviar, 00 for medium tones, and 0 for the darkest. Formerly, the lightest grade was called Imperial or Royal Caviar, reserved exclusively for monarchical banquets.

While historically the best caviar was associated with the largest and lightest roe from wild sturgeon, today's gourmets are turning toward sustainability. The rise of high-end farmed caviar, such as that produced in Spain, offers textures and flavors that compete directly with Caspian classics, always depending on the subjectivity and sensory ecstasy of each taster.

Types of Caviar According to Processing

Depending on the treatment of the roe, we distinguish four main categories of caviar:

• 1. Malossol Caviar: The preference of purists. The Russian term Malossol means "little salt." It refers to fresh roe of the highest quality with a salt content of less than 5%, allowing one to appreciate the pure, nuanced flavor of the roe.
• 2. Salted Caviar: Also known as "semi-preserved." It contains up to 8% salt. While this process extends the product's shelf life, the original flavor may be slightly masked by the salinity.
• 3. Pressed Caviar (Payusnaya): Made from roe that has lost firmness or is overly ripe. It is pressed to create a concentrated paste. Despite its appearance, it is highly coveted by connoisseurs for its explosive intensity of flavor.
• 4. Pasteurized Caviar: Heat-treated and vacuum-packed. This method ensures prolonged preservation in glass, although the texture often becomes slightly firmer and the flavor loses some of its volatile freshness.

Main Sturgeon Caviar Varieties

1. Beluga Caviar: Comes from the Huso huso sturgeon. It is the most expensive due to the fish's scarcity and the maturation time (up to 20 years). Its eggs are the largest, ranging from steel gray to nearly black, with a sublime buttery texture.
2. Osetra Caviar (Oscietra): Procedes from Acipenser gueldenstaedtii. Its grains are medium-sized, and its chromatic range varies from dark brown to golden amber. It is famous for its unmistakable nutty flavor and fruity notes.
3. Sevruga Caviar: Extracted from Acipenser stellatus. It produces the smallest eggs but with a more intense, marine, and saline flavor. It is the most accessible variety among the three Caspian classics.

Gourmet Options and Quality Substitutes

The industry has evolved to offer sustainable luxury alternatives that do not envy the wild product:

• Farmed Caviar (Aquaculture): Spain is a European leader in this category. Thanks to pure waters and controlled diets, high-quality Eco-friendly caviar is produced from varieties like Baerii (Siberian sturgeon) or White Sturgeon, harvested at their optimal point of maturity.
• Paddlefish and Hackleback: Sourced from North American rivers. Paddlefish is a great substitute for Beluga due to its gray tone and soft texture, while Hackleback stands out for its shiny black, sweet grains.
• Salmon Caviar (Ikura): Vibrant orange and large in size. It is a favorite in Nikkei cuisine and sushi. Since it comes from a fish with scales, it is a suitable option for a Kosher diet.
• Trout and Lumpfish Caviar: Trout roe is subtle and elegant, while lumpfish (typical of Nordic countries) is an economical option ideal for appetizers and garnishes, providing a crunchy, marine touch.
