OSR is an awkward honey ( for beekeepers at least) as it can set before it's water content is reduced to below the level at which the bees would usually cap it. Bees must have a mechanism to determine whether honey should be capped or not (by sensing the water content of the honey or viscosity or both?), so to cap it when still wet is against their genetic programming. The abundance of OSR honey is not something that bees would have evolved to handle. Do bees cap honey that has already set in the frames or leave it be?
May your bees read the same books as you do.
