On Fining Liquors
Isinglass is almost universally used in fining liquors. Take about half
an ounce to the barrel--beat it fine with a hammer, lay it in a
convenient vessel, pour thereon two gallons whiskey, or a like quantity
of the liquor you are about to fine, let it soak two or three days, or
till it becomes soft enough to mix--then stir it effectually, and add
the white and shells of half a dozen eggs--beat them up together and
pour them into the cask that is to be fined, then stir it in the cask,
bung it slightly, after standing three or four days it will be
sufficiently fine, and may be drawn off into a clean cask.
