Preparation.—"Vanilla, cut into small pieces and bruised, one hundred grammes (100 Gm.) [3 ozs. av., 231 grs.]; sugar, in coarse powder, two hundred grammes (200 Gm.) [7 ozs. av., 24 grs.]; alcohol, water, each, a sufficient quantity to make one thousand cubic centimeters (1000 Cc.) [33 fl℥, 391♏︎]. Mix alcohol and water in the proportion of six hundred and fifty cubic centimeters (650 Cc.) [21 fl℥, 470♏︎] of alcohol to three hundred and fifty cubic centimeters (350 Cc.) [11 fl℥, 401♏︎] of water. Macerate the vanilla in five hundred cubic centimeters (500 Cc.) [16 fl℥, 435♏︎] of this mixture for 12 hours, then drain off the liquid, and set it aside. Transfer the vanilla to a mortar, beat it with the sugar into a uniform powder, then pack it in a percolator, and pour upon it the reserved liquid. When this has disappeared from the surface, gradually pour on menstruum, and continue the percolation, until one thousand cubic centimeters (1000 Cc.) [33 fl℥, 391♏︎] of tincture are obtained"—(U. S. P.). This tincture represents what was known as Fluid extract or Essence of vanilla. It is, however, much stronger than commercial extract of vanilla (1 ounce to 1 pint). When added to syrup in the proportion of ounce to pint, it yields a good Syrup of vanilla.
Uses.—Tincture of vanilla is used exclusively as a flavoring substance.
