One cause incidental to this evil is, using the brewhouse for the purposes of washing, which ought never to be permitted, where any other convenience can be had; for nothing can be more injurious than the remains of dirty suds, left in vessels intended for brewing only. Nor should water be suffered to stand too long in the coolers, as it will soak into them, and soon turn putrid, when the stench will enter the wood, and render them almost incurable. More beer is spoiled for want of attention to these niceties than can well be imagined, and the real cause is seldom known or suspected; but in some families, after all the care that is taken in the manufacture of the article, the beer is never palatable or wholesome.--Barrels should be well cleaned with boiling water; and if the bung-hole will admit, they should be scrubbed inside with a hard brush. If they have acquired a musty scent, take out the heads, and let them be well scrubbed with sand and fuller's earth. Then put in the head again, and scald it well; throw in a piece of unslaked lime, and close up the bung. When the cask has stood some time, rinse it well with cold water, and it will then be fit for use. New casks likewise require attention, for they are apt to give the liquor a bad taste, if they be not well scalded and seasoned several days successively before they are used; and old casks are apt to grow musty, if they stand any time out of use. To prevent this, a cork should be put into every one of them as soon as the cock or fosset is taken out; the vent and the bung-hole must also be well closed. The best way to season new casks is to boil two pecks of bran or malt dust in a copper of water, and pour it in hot; then stop it up close, and let it stand two days. When the cask is washed and dried, it will be fit for use.
