Hello
I've recently read that some wine fining processes use isinglass or bone charcoal. Can anyone tell me if this is true and if it is, which wines are most likely to use this process. Would it be used in champagne?
The article also said that some wine makers use dried blood in fining. Surely this isn't true!!!!?
Would appreciate it if anyone in the know can shed some light on this.
Thanks
Louise

Several items are used for fining:

Bentonite - An aluminum-silica clay product

Silica Gel

Casein - A milk protein

Isinglass - Dried air bladder of the sturgeon

Egg Whites

Gelatin

Dried Blood - Acts about the same as gelatin. It is out of favor now due to the potential for serious viral infections.

The first four are often used in white wines. Drink up, the wines are safe, although dried bladder does not present a pretty mental picture.
