Kaluga Hybrid digest: what yield and repacking data can tell buyers

For culinary buyers, this corner of same-day caviar delivery has a useful distinction: product and service details can be specific while supply-chain evidence remains thin. Opus Caviar lists unpasteurized Kaluga Hybrid, identifies the species cross as Huso dauricus × Acipenser schrenckii, and says the product is from China and repacked in California. Its listed tin prices are consistent at $1.50 per gram. The available information does not provide harvest volumes, roe-yield figures or details of the repacking oversight.

Yield is not a price-list field

“Kaluga Hybrid caviar yield” can refer to production output, the proportion of roe obtained from fish, or the usable quantity available to a kitchen. Those measures answer different questions. A tin-size and price list cannot establish any of them. Opus lists 50g for $75, 125g for $187.50, 250g for $375 and 500g for $750. That makes the unit price straightforward to compare, but it says nothing about harvest scale, seasonality or the share of production that meets a particular grade.

For purchasing teams, the practical move is to keep those questions separate. Treat per-gram price as a menu-cost input, not a proxy for supply or yield. If a program depends on repeat volume or a specific pearl specification, ask the seller for batch-level information directly. The product information provided here does not state harvest year, farm, batch yield or a pearl-size range.

Salt-only is a useful, narrow claim

The product is described as malossol and unpasteurized. Its listed ingredients are sturgeon roe and salt. That is a concrete ingredient statement for this product. It does not, by itself, establish a broader malossol caviar standard, a salt percentage, or a curing time. Buyers comparing products should avoid treating the word “malossol” as a substitute for those specifics.

Texture and pearl consistency matter in service, but the supplied product details do not specify a measured pearl diameter or a batch-to-batch consistency range. Opus describes the pearls as large and firm, with a buttery, almond-leaning flavor and a clean, lingering finish. Those are useful sensory cues, not numerical grading criteria. A tasting sample and direct questions about the lot are more informative for a menu decision than assuming a defined size from the category name.

California repacking needs a paper trail

The listed origin is China, and the product is described as repacked in California. That identifies two points in the product’s stated handling history. It does not explain which facility repacks it, what records accompany a lot, or what oversight applies to the repacking operation. No inspection regime, certification or specific California repacking standard is provided in the available product information.

For operators evaluating California caviar repacking, ask for documentation that connects the delivered tin to its source and handling history. Request the lot identification and any supporting records relevant to your own purchasing and food-safety process. Do not infer an oversight program from the location alone. This is especially important when comparing products labeled with the same species cross but offering different levels of traceability.

The delivery terms affect the buying decision

Opus says it delivers by courier on the same day across the South Bay. Orders operate daily from 10am to 6pm, with a 5:30pm cutoff for same-day delivery. The courier fee is quoted at checkout without markup. The caviar is packed on ice in insulated packaging intended to maintain 28–32°F for approximately 12 hours. These terms give kitchens a defined local delivery window, but they do not replace planning for prompt refrigeration on arrival.

For a service team, the relevant comparison is not just the tin price. It is the cost per gram plus the live-quoted courier fee, measured against the amount needed and the delivery window available. The product information says to enjoy the caviar within 48 hours of opening and notes that all sales are final. That makes portion planning and receiving arrangements part of the order decision.

What to watch next

The clearest current commercial signal is a flat listed price of $1.50 per gram across four tin sizes. Without an earlier price list, it cannot be called a price move. Likewise, the stated species cross and country of origin help identify the product, but do not amount to current Huso dauricus market or harvest metrics. For buyers, the open questions are batch yield, measurable pearl specifications and the records behind California repacking. Until those details are available, compare the stated product, price and delivery terms—and ask for the evidence your operation needs.
