so my mead has been aging in my frig with the bung and air lock on it for about 9 months now in secondary and i been tasting it along the way, i never added potassium metabisulfite or potassium sorbate. i want to back sweeten and bottle now, should i take this mead out of the secondary and add both potassium meta and potassium sorbate let it sit another day and then bottle?
