Clean whiskey, sixty gallons; water, forty gallons; tincture grains of paradise, two gallons; tincture of mustard, half a gallon (tincture of mustard is made by digesting one pound of ground mustard in half a gallon of whiskey, for thirty-six hours); one ounce of sulphuric acid; two ounces oil of juniper, dissolved in half a pint of alcohol; nitric ether, six ounces ; fine this by the addition of four ounces of powdered alum.
Gin Cordial. - Of the oil of bitter almonds, sul phuric acid, turpentine, and juniper, half a drachm each; dissolve these in alcohol, fifteen gallons clean spirit, and add one drachm coriander seed, two ounces bruised orris root, ten pounds of sugar, dissolved in four gallons of water; mix the whole.
Pure Irish and Scotch whiskey contain about fifty-two to fifty-five per cent, of alcohol, which would be equal in strength to pure French brandy.
The fancy brands of American whiskey contain from thirty to forty-eight per cent, of alcohol. A choice article of whiskey, which would not require the addition of foreign substances, should contain fifty-two per cent, of alcohol, freed of its grain oil; the aromatics necessary in the production of this whiskey, will conceal a considerable portion of grain oil.
Novices are apt to disregard all rules in adding foreign substances to liquors, acting under the impression that each substance imparts a peculiar virtue, and the mistake is not obvious until the liquid has been spoiled.
Experience has long since proven, that saccharine matter and starch will impart all the necessary and most desirable qualities to plain spirit.
Clean spirit, ninety-two gallons; water, thirty-five gallons; honey, dissolved in three gallons of water, six gallons; creasote, fifty drops; color slightly with burnt sugar.
Rectified whiskey, thirty gallons; creasote, ten drops; tincture grains of paradise, one quart decoction of strong tea (see directions for making), three quarts; thirty-five pounds, or less, of clarified sugar, dissolved in eight gallons of water; mix the whole, and color with a pint of tincture of sanders, and the same of burnt sugar coloring.
Cleaned alcohol, ninety-two gallons; water, thirty-five gallons; refined sugar, thirty pounds, dissolved in six gallons of water; creasote, thirty drops; water of ammonia two ounces.
Rectified whiskey, thirty gallons; grains of paradise tincture, three quarts; catechu, two ounces; creasote, ten drops; water, five gallons; mix the liquor before it is charged with any of the articles. It should be passed through a bed composed of ground oatmeal, or of ground rice, or of a mass composed of three parts of unground rice, to one part of wheat flour. This bed should be about twelve inches in depth, and for convenience can be arranged in an empty whiskey barrel. Full instructions for this will be found under the head of " Filtering." The spirit should pass with rapidity through the filter, and if it comes off too highly charged with starch, it should have clean spirit added until the starch becomes dissipated, or is not perceptible to the naked eye; or if the spirit should be too heavy, or cloudy, run it through the sand filter alone, until it comes out bright. The amount of flour necessary to impart the desired flavor to the spirit, is not distinguishable by the naked eye; and neither should the liquor have the slightest tinge imparted to its original color.
