Sturgeon roe, processed and salted, ranges in color from jet black to pale gold, with shades of gray, brown, and green also occurring. The specific hue depends on the species of sturgeon, its diet, and the processing methods employed. For instance, Beluga caviar is typically dark gray or black, while Osetra can be golden brown or a deep amber.
The color of this delicacy often indicates quality and price. Historically, darker shades of black were associated with rarer, more desirable varieties, commanding higher prices. However, color alone is not a definitive indicator, as other factors like size, texture, and flavor profile also contribute significantly to its overall quality. The variations in hue offer a fascinating glimpse into the diverse world of sturgeon and their unique environments.
