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

per

·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;
