Genuine sturgeon roe typically ranges in color from jet black to dark brownish-gray, with lighter gray and even golden hues depending on the species and maturity. For instance, Beluga caviar often exhibits a light gray or even slightly translucent appearance, while Ossetra tends toward a browner-gray or gold. Color variations can also be influenced by processing methods, including the use of borax or other preservatives.
The shade is a significant factor in determining quality and price. Darker shades are often associated with younger fish and can command higher prices. However, the focus on color should be considered alongside other factors like size, texture, aroma, and flavor. Historically, certain hues were prized by imperial courts and aristocracy, contributing to the cultural significance associated with specific varieties. This historical preference continues to influence modern perceptions and market value.
