How long is "some time now"? How does it taste? 1.016 should be semi-sweet, about 12% abv. By BJCP standards, that's a Standard Semi-Sweet mead. If you want it drier, maybe some champagne yeast. I think if it were me (I happen to like semi-sweet), I'd go ahead and add my potassium sorbate, maybe let it bulk age, or at least make sure everything has settled out, then bottle and enjoy!
