Re: H2s odor still lingering



Not sure how that would help, I think you might want to consider Copper
Sulfate. An old trick to add a little copper to the wine was to rack
it through some copper tubing but you are running out of time if this
has been going on for months. Copper in foodstuffs is considered a
poison at some point so it's nothing to fool around with.

Margalit describes a simple procedure to see if copper sulfate will
work in 'Winery Technology and Operations'; if you can't get a copy of
it Ii can sum it up in a post.

I have a large batch of blackberry (18 gallons) that I started in early

still notice a slight H2s odor?
Does anyone have a cure for this residual odor, I thought I read
somewhere in the past that treating with Potassium Sorbate may help but
can't remember any details.
