The proof of the restored distillate is then determined by use of a precision hydrometer and thermometer in accordance with the provisions of §13. . Unknown values signify that the exact specific density value is unknown, however the liquor is still in approximately the right location in the chart. Most recipes are written with the heaviest liqueurs printed first. Each liqueur weighs differently and either floats or sinks when added to another. The temperature of this sample will be controlled automatically to within ±0.
The weight of each liquid is measured by its specific gravity. The point where this line intersects the hydrometer scale is the correct reading of the hydrometer. The relationship between ethanol density and strength can also be shown on a graph see below. The non-linearity is not obvious when using a computer program or tabulated data to determine the ethanol density, even though the density vs composition behavior is accurately represented. This table may also be used for ascertaining the quantity of water required to reduce to a given proof.
Homemade sloe gin will vary as well. The weight for containers of a capacity of 10 wine gallons or less shall be determined in pounds and ounces, or pounds and hundredths of a pound, and shall be recorded in pounds and hundredths of a pound. Or input the concentration to get the corresponding density. Temperature correction factor Table 7 —0. If the weight must be marked on the container in pounds and decimal fractions of a pound, it will be necessary to convert the ounces to hundredths of a pound. Alcohol facts Take a look at a few curious facts associated with alcohol and drinking. When layering drinks, the mixer must keep the alcohol's density in mind to combine the right liquids.
To pour the liqueurs into the glass, simply use the rounded or back part of a spoon and rest it against the inside of the glass. The strength or concentration of an ethanol-water mixture can be expressed in several different ways. As shown, the final proof is rounded to the nearest tenth of a degree of proof. However, if the spirits contain solids in excess of 600 milligrams per 100 milliliters, the wine gallon and proof gallon contents shall be determined as prescribed for such spirits in §30. People enjoyed these captivating layers of spirits and syrups in their everyday lives. Where either the weight or the proof of a quantity of spirits is beyond the limitations of this table, the number of proof gallons may be ascertained by reference to Table 3. Name Specific Gravity Colour Southern Comfort 0.
Hydrometer readings should be made to the nearest 0. Alcohol concentrations may be determined in the full range of 0 to 100% with a single measurement. Determine the specific gravity of the undistilled sample, distill and restore the samples as provided in paragraph c of this section and determine the specific gravity of the restored distillate by means of a pycnometer. In the case of metal packages the tare established at the time of filling may be used unless it appears to be incorrect. In general, the higher the proof number of the alcohol, the lighter it will be.
To do this, divide the proof gallons of spirits to be reduced by the fractional part of a proof gallon per pound of spirits at the proof to which the spirits are to be reduced, and subtract from the quotient the net weight of the spirits before reduction. It is necessary to interpolate in Table 1 for fractional hydrometer and thermometer readings. In the drink world, we compare the density of water with a specific gravity of 1 to the liquid we are measuring to get its specific gravity. History of alcohol For thousands of years, people have used fermented grain, fruit juice, and honey to make alcohol. In the sixteen century, alcohol called 'spirits' was largely used for medical purposes. Another alternative for presenting ethanol density data is to use a table.
From the proofs and the net weights of the packages, the wine gallons if desired and the proof gallons of spirits shall be determined by the use of Table 2. Hydrometers are designated by letter according to range of proof and are provided in ranges and subdivisions of stems as follows: ------------------------------------------------------------------------ Precision Range Subdivision ----------------------------------------------------------------------- F. For cases containing bottles filled according to the metric system of measure, the quantity determined shall be converted to wine gallons, as provided in §19. In a shelf-pull or audit all that matters is accuracy in reporting alcohol by volume. . When withdrawing a portion of the contents of a weighing tank, the difference between the quantity ascertained by proofing and weighing in the tank immediately before the removal of the spirits and the quantity ascertained by proofing and weighing in the tank immediately after the removal of the spirits shall be the quantity considered to be withdrawn. Table 6 shows the volumes of alcohol and water and the specific gravity air and vacuum of spirituous liquor at each proof.
Several Native American civilizations developed alcoholic beverages in pre-Columbian times. The slight variation between this table and Tables 2, 3, and 5 on some calculations is due to the dropping or adding of fractions beyond the first decimal in those tables. . Fermented drinks beer or wine contain from 2% to 20% of alcohol. These layered drinks could get quite extravagant.
