Beer Yeast Enhances
the Flavor of Yellowtail
By incorporating beer yeast into the feed, the fish naturally develops higher levels of
inosinic acid and glutamic acid, key compounds responsible for rich umami.
Green tea catechins, kelp powder, and polyphenols further improve freshness and flesh quality
through their natural antioxidant properties.
We also carefully age each fish to further enhance its flavor
and deepen its natural umami.
