I have never purchased honey from Costco, not their fault, but any honey that is perfectly clear has been filtered. It is actually illegal to completely filter honey and one reason it is done is to hide the origin on the honey. They are filtering out all the pollens that would tell a lab where the honey came from.
Nope, it's now just a processed food and I rather spend the money to get local stuff, or get stuff on sale.
Also some of it is not honey. Sometimes its doctored with corn syrup. Most of the time the ultrafiltered honey is imported from China.
