In retail settings, red caviar is commonly found in glass or metal jars. With rising packaging costs, many producers are increasingly turning to plastic containers. Olga Kalaydzhyan, head of purchasing at the PUTIN company, spoke with socialbites.ca about whether packaging changes alter the taste of caviar. [Source: Expert interview]
Glass jars offer chemical inertness, durability, and strong odor insulation. Vacuum-sealing glass provides excellent protection from oxygen and preserves freshness. The environmental benefit is a key advantage since glass is highly recyclable. However, glass packaging requires careful handling during transportation, and the cost of a glass jar can add up to 200 rubles to the product price. [Source: Expert interview]
Tin packaging is airtight and durable for shipping. Its main edge is a lower price point compared with glass, making it attractive for bulk distribution. [Source: Expert interview]
Open metal containers pose a risk. If the seal breaks, air enters and the caviar can oxidize, which may impart a metallic flavor. For this reason, consumers are advised to finish opened caviar within 48 hours. [Source: Expert interview]
Plastic is widely used for large-quantity packaging and is also available in retail lots. A crucial detail is that plastic packaging generally lacks a vacuum inside. [Source: Expert interview]
Plastic lids with locking valves can seal content, but they do not achieve true vacuum. As a result, shelf life is shorter, typically from 15 to 30 days. This is important for buyers planning a later purchase. [Source: Expert interview]
The expert also disputed the notion that the most delicious caviar comes in glass. Packaging alone cannot guarantee superior taste; the seal’s integrity matters most. Higher glass prices usually reflect packaging costs rather than product quality. More elaborate shapes or ornate decorations tend to raise the price. [Source: Expert interview]
Another common myth is that a glass jar should pop when opened. If no popping occurs, it may indicate the vacuum is compromised and the product should not be consumed. The absence of a popping sound does not always signal spoilage; it can depend on the jar lid type. The presence or absence of a valve affects whether a popping sound occurs.
