Fining out oxidation
 

I've got a batch of pear wine that is slightly brownish in color. Assuming
this is the result of oxidation, what can I do to remove (or at least,
reduce) the browning? It seems I've read somewhere that some fining agents
will remove the color...

Thanks,

Bart

Try casein and/or PVPP. Bench testing is ideal, but roughly I'd say
you'd be looking at ballpark figures of 0.5-1 g/l for the casein and a
few hundred mg/l PVPP if you use it.

Bart, see my entry for June 25, 2003 at
http://www.homebrew.com/wine_cellar/wineblog.shtml. Your best bet for
removing oxidation browning is Polyclar Ultra K-100. If you cannot
find that, use Polylact.

Jack,

I like Homebrew Adventures (buy from them routinely) and your blog, too.
However, it seems there are entries for 6/28th and 6/16th, but no 6/25th.

Bart, the devil is in the details. Try again, and this time go to
2003, not 2004....

Oops!... Sorry 'bout that... I found the entry, and ordered a supply of
Polyclar.

Thanks for setting me straight!
