Just splash racked my dandelion a second time, there was still a faint scent of rotten egg in it after the last racking. Anyways, in a rush I made the mistake of using my syphon without having cleaned it from the last racking. So it's been sitting there a week without cleaning. I'm a little worried about bacteria now, should I add more campden? Or will the initial dose added with my recipe be good enough? I'm sitting around 6 weeks right now.
