Isinglass and Kieselsol?

Works great for many white wines, but the first thing to add is bentonite. Follow that with the kieselsohl, then the isinglass.

I'd recommend that you do fining trials first. Treat all samples with ~2-3 lb/1000 gallons bentonite and 1 lb/1000 gallons kieselsohl. Then try several additions of isinglass, in the range of 1/9, 1/6 and 1/3 pound/1000 gallons, as well as a control sample with no isinglass.

Be sure to properly hydrate the bentonite and isinglass before use. IOW, don't just dump it in dry. Peynaud's book has a good section on this topic.
