DISTILLATION.

grains everything soluble, about 700 gallons of boiling hot water are turned in upon them, thoroughly incorporated, then left quietly to infuse, and drawn off as before. This weak wort is commonly reserved for the first liquor of the next mashing operation, upon a fresh quantity of n1eal and malt. With the proportion of rnalt, raw grain, and water above prescribed, the infusion first drawn off may have a strength == 20 per cent. == spe– cific gravity 1·082, or 73 pounds per barrel; the second of 50 pounds per barrel, or 14 per - cent.; and the two together would have a strength of 61 ·2 pounds per barrel== 17 per cent., or specific gravity 1 ·070. From experi– ments carefully made, upon a considerable scale, it appears that no more than four-fifths of the soluble saccharo-starchy matter of the worts is decomposed, in the best regulated fer– mentations of the distiller from raw grain. For every 2 pounds so decomposed, 1 pound of alcohol, specific gravity 0·825, is generated;
