Short answer: Costco is one of the best-value places to buy farmed Osetra in larger sizes, provided you have a membership. Its cheapest sturgeon caviar per ounce is Plaza Osetra Kilo Pack (1 kg) at $39.69/oz. For a non-sturgeon option, its Alaska chum salmon ikura works out to $5.68/oz.
What Costco sells
Costco's online caviar range is Plaza Osetra (farmed Bulgarian Osetra, plus Golden Osetra), Tsar Nicoulai (Baerii and California white sturgeon) and Golden Goat. Everything is listed as online-only. We didn't find a Kirkland Signature caviar. Taste is subjective, so we don't score it. What we can tell you is the price per ounce compared with the other 11 Osetra listings we track.
