1451. To Ascertain How Much Water Should be Added to Spirits

1451.    To Ascertain How Much Water Should be Added to Spirits, to Reduce it from a Given Degree of Strength to a Lower Degree or Percentage of Strength. The manufacturer may sometimes find it necessary to reduce or increase the strength of spirit, according as circumstances may require. To accomplish, this, we give the following rules, which will be found useful to the dealer: multiply the number of gallons by the actual degree of strength of the spirit, and divide the amount by the degree of strength sought to be obtained, and from the answer subtract 100; the amount thus obtained will show the quantity of water to be added to the spirit in order to reduce it to the degree sought. For example : suppose you have 100 gallons of spirit at 80° by Tralles' hydrometer, and wish to reduce it to 50° or proof. Multiply 100 by 80, and divide the amount by 50, then from the answer subtract 100; this will show that 60 gallons of water must be added to the spirit in order to reduce it to 50° Tralles', or proof.

1452. To Ascertain the Quantity of Pure or Absolute Alcohol in any Given Amount of Liquor

1452. To Ascertain the Quantity of Pure or Absolute Alcohol in any Given Amount of Liquor. The quantity of alcohol contained in any amount of liquor is readily ascertained after testing the strength with Tralles' hydrometer at 60° Fahr., by simply multiplying the figures expressing the quantity of liquor, by the ascertained strength; for example: a barrel of brandy containing 32 gallons, 60° strong at 60° Fah., contains 191/5 gallons pure alcohol. Rule.- Multiply the number of gallons by the ascertained degrees of strength, and divide by 100. Thus : 32 gallons, 60° Tralles' at 60° Fahr.

19.20, or 191/5 gallons pure alcohol.

1453. To Ascertain the Number of Gallons at any Required Number Below Proof, in any Given Number of Proof Gallons

1453.    To Ascertain the Number of Gallons at any Required Number Below Proof, in any Given Number of Proof Gallons. Multiply the given number of proof gallons by 100, and then divide the product thus obtained by a number found by deducting the required number of degrees below proof from 100. The quotient will be the answer. For example: How many gallons, 25 below proof, are there in 35 gallons proof?

25 b. p. 100

We thus see by the above example that 35 gallons proof spirit is equal to 461 gallons 25 below proof.

1454. To Increase the Strength, of a Spirit from any Degree to a Higher given Degree, or Percentage

1454.    To Increase the Strength, of a Spirit from any Degree to a Higher given Degree, or Percentage. To increase the degree of strength of a spirit, multiply the number of gallons by the actual degree of strength of the spirit, and divide by the degree of strength sought to be obtained. For example: suppose you have 100 gallons of spirit at proof, or 50° by Tralles' hydrometer, and wish to increase its strength to 80°. Multiply 100 gallons by 50 and divide by 80 ; the answer will give you the number of gallons of spirit, 621/2, to be added to the 100 gallons in spirit in order to increase its volume to 80° by Tralles' hydrometer.
