15 Mode of ascertaining original gravity
When fermentation has commenced in any worts so that the original gravity cannot be ascertained by the saccharometer, such gravity may be determined in the following manner:
(1) A sample is to be taken from any part of such worts and a definite quantity thereof by measure at the temperature of sixty degrees Fahrenheit shall be distilled:
(2) The distillate and residue shall each be made up with distilled water to the original measure of the quantity before distillation, and the gravity of each shall be ascertained:
(3) The number of degrees by which the gravity of the distillate is less than the gravity of distilled water shall be deemed the spirit indication of the distillate:
(4) The degrees of original gravity standing opposite to such spirit indication in the Table in the First Schedule to this Act added to the specific gravity of the residue shall be deemed to be the original gravity of the worts.
