Tried these after having the Brunswick plain skinless/boneless. They are of exactly the same quality, but with the addition of two or three skinny little red peppers. The ingredient list also states vinegar and citric acid, but it's hard to tell if that's added to the olive oil, or just required to be stated because it's in the peppers.
They are skinless/boneless pilchards, with the peppers adding a not-overpowering spicy pepper flavor. Not much else to add. I like them and have re-ordered them multiple times.
A bit of background, Brunswick was a Canadian cannery dating back to the late 19th century. It was acquired by Bumblebee, and some say the quality has suffered as a result. There's no way to make that comparison now, but suffice it to say the quality is on par with other well-regarding contemporaries.
Anyway, this is a definite try it/buy it again selection, and hard to beat at just over $2 a can. Available individually, or in lots of six or twelve at Amazon.
