I would say ever frame has it's own unique taste, though not very different form those around it. I have not harvested yet this year but two years ago I got a dark brown wild flower, and last year was a light yellow clover, that we called "urn sample" because of it's weedy taste, still good though. Always I notice small groups of cells containing red honey. I have been meaning to track down the plant that causes this just to make a field of them and see what it tastes like. I imagen it is some sort of tree that only blooms for a week though.
