Independent market intelligence for objectively comparable caviar. Transaction-led in design, source-linked in evidence, methodology-first in principle.
Production and prices describe different moments and are never blended into one figure. Every number carries its source, year and status, and where the public record disagrees with itself, the gap is shown rather than smoothed away.

The mathematics behind Cavport, each measure with its status and the data it still needs. Read the measures
What Cavport deliberately does not show until it is verified. See what we withhold
Public list-price and asking-price observations from retailer pages. Point-in-time, source-linked, not transaction-confirmed. Separate from any verified reference.
The institutional end state: verified arm's-length transactions, evidence tiers, clean-team processing, aggregation and suppression. Preserves the CQR / CMR terminology, published only once the methodology's gates are satisfied.
Professional caviar market intelligence. Historical series, full pack-size analytics, country and seller-balanced views, distributions, watchlists, alerts and licensed exports. A separate authenticated product, built only when the data and the infrastructure are real. There is no live sign-in yet.
Versioned, public, and separated into an active public-monitor layer and a pre-launch verified-reference layer.
Every public figure traces to the retailer page it was observed on. The source of record is the webpage, not any research tool.
Each snapshot has a permanent identity. Historical releases are not silently overwritten.
Structural separation from certification, with controls stated as adopted design versus operational implementation.
