Rotten Egg Smell

[pikmin969]

Just racked my mead into a bucket for secondary, and I noticed a rotten egg-like smell. I've heard from a friend that using a bit of copper can clear out the smell, and that the batch should be fine so long as I get it out. I have a spare copper pressure tube cap that I can sanitize (still in its packaging), if I drop that in there and let it sit through the secondary fermentation will that do the trick? This is my first batch of mead

Hi and welcome to HBT!

The rotten egg smell is hydrogen sulfide. I have a detailed article about it here:

I took 2 samples out and but the copper pressure cap in one and left the other alone. The copper made a big difference, so I'll be using copper to try and treat the smell. Thanks for the help!
