I've got a stinky, sulfury cider that tastes good, but smells awful. While fermenting it let off rhino farts that would kill a rhino. I left it in primary for at least a month. It finished around 1.000 on the hydrometer, but still stunk. I then kegged and force-carbed hoping it would de-stink it. No luck.
I've tried shutting off the gas and leaving the vent open for 2 days. That didn't do much. I carbed it again, shut off the gas, and I've been shaking and releasing the pressure for 2 more days. I'm still getting the stink, but not as bad. It is almost flat now.
Is there anything else I can do to save it? It really does taste ok, but it is hard to enjoy when it smells like rotten eggs.
