Is the white substance on the surface of the honey foam?
During our processing, as we pump, filter and fill bottles, air is unavoidably mixed into the honey. Honey, being a viscous solution, has a tendency to trap this air. After the filling step, this air will slowly rise to the top of the honey leaving a white ring of foam. The larger the container, the more foam present. The foam gradually dissipates as the entrapped air bubbles burst.
