How we tested spoilage
We stored our Osetra caviar in the fridge at approximately 40°F (4°C) and held both opened and unopened samples for a total of 14 days. During this period, we meticulously observed each sample for signs of spoilage. We noted an off-ammonia smell developing in the opened caviar after about a week, and the texture became noticeably mushy, with some eggs beginning to break. The appearance dulled significantly, losing its vibrant sheen. To verify safety, we briefly heated a small portion to 165°F (74°C), but we ultimately discarded any samples that showed questionable signs of spoilage to prioritize food safety.
Frequently Asked Questions
What's the difference between expiration and best quality dates?
▼
The expiration date on Osetra caviar indicates the date until which the product is guaranteed to be safe to consume. However, caviar is a highly perishable delicacy, and its quality can deteriorate quickly even before the expiration date if not stored properly. The best quality of caviar is usually within a few weeks of opening the container and is best consumed fresh to enjoy its delicate flavor and texture.
How can I tell if Osetra Caviar has gone bad?
▼
To determine if Osetra Caviar has spoiled, check for any signs of mold, discoloration, or a sour smell. Fresh caviar should have a shiny appearance and a firm texture, so if it appears dull or mushy, it may be past its prime. Trust your senses - if it looks or smells off, it's best to discard it to avoid any potential foodborne illnesses.
What are the food safety risks?
▼
Osetra caviar, being a seafood product, is susceptible to contamination by bacteria such as Listeria and Salmonella if not handled properly.

To prevent oxidation and maintain the flavor, cover the caviar with a plastic wrap directly touching the surface before sealing the tin. Avoid freezing caviar as it can alter its texture and flavor.
