What each ingredient does

Isinglass
Fining agent that collects suspended yeast and haze so they settle out, clearing the beer.

The step that matters

Boiling the isinglass until fully dissolved. Isinglass is a collagen-based fining agent that must be fully dissolved to disperse evenly through the beer. Undissolved pieces won't clarify properly and can leave cloudiness or specks.
