Fresh Grouper Flavor Profile

Grouper Flavor Scale

Fresh Grouper is a member of the serranidae family which also includes sea bass. Chefs-Resources’ Grouper page shows when fresh Grouper is available, what it’s flavor profile and taste is like, the butchering yield % so you can determine your yield percentage for plate costing purposes. You will also find a Grouper nutrition table, the Flavor Scale, and links for further research.

Grouper is a lean, moist fish with a distinctive yet mild flavor, large flakes and a firm texture. The Red Grouper has a slightly sweeter, milder flavor than the Black Grouper and is considered to be the better of the two. Grouper’s flavor profile is like a cross between Bass and Halibut. Even though it is lean, this fish is forgiving during cooking and can be rather difficult to “over cook” in the sense of drying out.

Grouper Fish Description (Epinephelus morio, Mycteroperca bonaci)

There are three different fish which are known as Grouper in the US market; the Red Grouper, (True) Black Grouper, and Gag which the market commonly calls Black Grouper. True Black Grouper is hard to come by. Both True Black Grouper and Gag have a higher yield and firmer texture than Red Grouper. Groupers in general have big heads, large mouths and heavy, stout bodies. They are not distance swimmers but prefer to dwell in bottom structures such as rock protrusions and reefs. They also use their powerful gills to create small caves for themselves to inhabit.

Red Grouper comprises about 70% of the U.S. grouper harvest and is therefore the most commonly found grouper in the market place with an average market size of between 5 – 15 lbs for whole fish. Black Grouper and Gag range in market size from 15 – 20 lbs for whole fish.

Range & Habitat

Red & Black Grouper RangeAquaMaps     Data sources: GBIF

Red, Black and Gag Grouper are the predominant Groupers sold to US markets and are found from the mid-Atlantic States down through the Gulf of Mexico and both coasts of South America.

There are other Groupers sold to other countries, or caught by sport fisherman, which are found in other regions worldwide.

Additional Culinary Notes

Groupers are a reef dwelling fish so there is the possibility of Ciguatera poisoning. Ciguatera is caused by eating certain reef fishes whose flesh is contaminated with toxins originally produced by dinoflagellates associated with red tide. Ciguatera cannot be destroyed by cooking. Check with your vendor to avoid fish harvested from known hot spots.

Groupers are of course available from many countries – lot of live product goes into Hong Kong and starting to be reasonable quantities of aquaculture. In Middle East known as Hammour – we were at restaurant couple of weeks back in Riyadh and purchased Hammour but received Pangasius/Basa……why do people do this??


It’s an unfortunate reality that some people/restaurants/purveyors have no integrity and will cheat the system in order to sell a cheaper product as if it is the more expensive product. This seems to be especially true with seafood where people who are less aware than you are may never even know that they were cheated. I believe that the USA is getting better at trying to crack down on abuses but I’m unfamiliar with the policies in the Middle East. If they have a way to report the abuse then that is the first step in stopping the unethical selling/naming… Read more »
