For Fresh Bluefin Tuna (never frozen): Fresh Bluefin Tuna can be stored in the refrigerator for sashimi use immediately upon arrival. For raw consumption, eat within 1-2 days. Any longer and the tuna will become searing, poke, or cooking grade. You can also freeze these portions immediately upon arrival and store for up to one week for sashimi use or 10 days for poke, searing, and cooking preparations (keep in mind that freezing sashimi grade fish in a conventional home freezer diminishes the quality of the fish. Rule of thumb-- eat it while it's fresh!

For Superfrozen Bluefin Tuna: Superfrozen Bluefin Tuna can be stored in a conventional home freezer for approximately 1.5 weeks before oxidation occurs (change in color).


Method I: Place superfrozen product in cold water (preferably an ice bath) for 20 to 30 minutes, until thawed. Remove the portion from the plastic, pat dry and wrap with our white butcher paper provided. Cut and enjoy within 24 hours.

Method II: Remove the portion from the plastic bag, wrap with a paper towel and place in the refrigerator overnight. Cut and enjoy within 24 hours.

Riviera Seafood Club's Fresh Pacific Bluefin Tuna Akami ('Hon-Maguro' in Japanese) is prized around the world for its rich, meaty flavor and delicate features. Our Bluefin tuna are responsibly caught in the wild, and then ranched in the pristine waters of Baja by Bluefiná. Each and every Bluefin is harvested to order, always utilizing the Ike Jime method to maximize flavor and texture. 

The Bluefin Tuna Spine is a rare delicacy underutilized by the general population. Once properly defrosted, preparation takes a sharp cleaving knife or a serrated edge to split the individual vertebra in half. The spinal jelly can be enjoyed straight out of the bone or spooned out for a truly unique shooter. People are pleasantly surprised by the clean and briny flavor as is ,but often pair with a small dab of other items like ikura, caviar, wasabi, etc.

Each section is 3-4 spinal links (about 1 oz of jelly total), individually packed and shipped using overnight delivery to your door.

Time your defrost process to a couple of hours before your meal for the optimal outcome.
