The ones you listed under Honk Kong is not it. It’s a Vietnamese brand but they do have distributors in Hong Kong and Thailand as well. Please correct this. Example Phu Quoc name after the fish sauce factory I. The city of Phu Quoc, Vietnam.
I totally agreed with you. This survey is totally BS.
All big businesses have been state-owned by VN government/local authorities.
Filipino fish sauce is cheaper and taste better.
Red Boat 40°N just happened to be toward the end of all the different sauces we tasted (blind). We both immediately agreed that this was easily the best so far. The taste is fish and salt, with a slightly sweet finish. It was remarked “Now this is what fish sauce should taste like.” There’s currently a lot of buzz around Red Boat. I’ll admit, I was skeptical. In the end Red Boat was the clear winner.
Phu, few of the fish sauce producers in VN are state owned. Most are located on Phu Quoc island, and most all are small family affairs. The big names like Three Crabs is actually a large-scale manufacturer in Hong Kong. I do like Patis (Filipino fish sauce), but to make a blanket statement like “Filipino fish sauce is cheaper and taste better” is just dumb. It tastes different. That’s like asserting that orange taste better than apples.
