Regiis Ova Caviar

A CURATION brand, and an unusually credible one: the selector is a three-Michelin-star kitchen buying for itself, and the company states it visits and technically qualifies every farm. But it is a label over a supplier network — Regiis Ova names none of its farms publicly, so a diner cannot get from the plate to a checkable origin. Named by three of our venues (Carversteak, Cote, Mizumi), which is why it matters that the chain stops at the brand.

Scale

Small — a chef-facing caviar brand, not a farming operation.

Feed & inputs

UNKNOWN — set by the unnamed partner farms.

Animal welfare

N/A for roe production as scored here; no aquaculture welfare standard published.

Environmental

States a mission to 'support sustainable farming'; no certification or standard named, so it scores nothing.

Transparency

MEDIUM. Open about being a selector rather than a farmer, and about who does the selecting — but the farms themselves are never named.
