I usually keep honey in a pantry cupboard, but I picked up a little jar of some honey at my local cookware shop today that comes from an esoteric blossom in Hawaii that grows only in black volanic ash. (Pfffffffffft.) It's got more of a whipped honey or honey-cream consistency, it has no preservatives, and it says it was never heated or filtered. Naturally, I had to sample a little bit of it as soon as I got home, and now that the jar's been opened, should I keep it in the refrigerator? The label doesn't say, either way.
