Isinglass finnings - smell
 
Hi

I use isinglass finnings to clear my beer. I have a 1 Litre bottle and use 100ml for 23 litres of beer. When I opened the new bottle and broke the seal is had no smell. 2 weeks later I used it on my next bach and the isinglass had quite a yuck smell to it.
It's now another 2 weeks later and I'm about to use it on another batch and it smells even worse!
The label on the bottle has no use by date or storage instructions.
Does this stuff go off? If it smells bad will it ruin the taste or flavour of the beer?

Cheers

Cool. I wonder how they figured out fish bladders clear beer really well.

Does it have a shelf life? If so what is it? Has anyone had a fishy smalling/tasting beer after using old isinglass?

I have never used it, and honestly know nothing about it, but if it was me...I dont think I would put stinky fish blatters in my beer.
