I don’t rack clear mead. It settles perfectly after a year or so, wait till laser beam goes through without any scattering, don’t agitate the bottle and give it time, mead really gets better on the long run.

Also, the more yeast you have, better is precipitation. Any rush makes imperfectly clear mead that would seem clear but would just settle in bottle later. This is a bad shortcut, don’t rake it.
