Beluga caviar is the roe (eggs) of the beluga sturgeon (Huso huso), known as the most expensive and luxurious type of caviar. The beluga sturgeon can grow very large, up to around 6 meters long and 2 tons in weight, with the caviar characterized by its large eggs, creamy texture, and rich, delicate taste. It is mainly found in the Caspian Sea and Black Sea regions, and due to the species being critically endangered, much beluga caviar today comes from sustainable aquaculture. The roe color ranges from light grey to dark grey or almost black, with lighter shades generally being more prized. Beluga caviar is typically served chilled with non-metallic spoons and pairs well with champagne, white wine, or vodka. The caviar is harvested under careful conditions, and the fish takes up to 20 years to mature to the stage where quality caviar can be obtained. "Caviar de Neuvic" is a noted producer of beluga caviar, sourcing from partner farms where Huso huso sturgeon are raised in conditions fed by snowmelt for optimal quality. The caviar from these farms offers large-sized eggs with a powerful taste and creamy texture. Beluga caviar is regarded as a luxury product, with prices varying widely but can be extremely high due to rarity and demand, sometimes reaching thousands of dollars per kilogram. Some variants, like the rare golden "almas" caviar from albino beluga sturgeon, can be even more costly. Thus, "caviar de beluga" refers directly to high-quality beluga sturgeon roe, a standard bearer of fine caviar worldwide.
