I have Margalit's book - I'll look that up, thanks.

Next day, huh? Well, I guess that first racking didn't work. Per
Keller's site, I am waiitng a month before another racking. Don;t know
what concentration I would try - that will be determined by what I can
get. Plan on seeing what I can order through the winestore outlets.

The problem with waiting is there is an increased chance the sulfides
will transform to mercaptans or disulfides, which are significantly
harder to get rid of. From past posts on this subjects, the copper
pipe/copper sulfate thing should work within minutes.

I ran into this problem from sort of a weird angle. It's a tayberry
wine that sat on the gross lees for about 10 days, but I never did get
any rotten egg out of it in the carboy. But when I racked it, there was
definitely something nasty there, not much but noticeable. So I tried
the copper pipe treatment and it didn't seem to help. So I'm not sure
what's going on but will do a mercaptan/disulfide test this weekend to
hopefully rule that out.

A good explanation of what to do can be found in Lum's book. Just
download it and search for copper. He talks about 1% copper sulfate
which is the most common one sold. I know Presque Isle sells it, I
keep it on hand; piwine/com. You should be able to find it many
places. The link:
