But since there is so much trouble in getting vessels sweet after they have been neglected, you ought to make all thorough clean after brewing, and once a month to fill your vessels with fair water, and let it off again in two or three days.
Suppose you take six bushels of malt, and two pounds of hops, and would make of it one barrel of strong, and two barrels of small beer.
Heat your first copper of liquor for mashing, and strew over it a double handful of bran or malt; by which you will see when it begins to boil; for it will break and curl, and then it is fit to be let off into the mash tub, where it must remain till the steam is quite spent, and you can see your face in it, before you put in your malt; and then you begin to mash, stirring it all the while you are putting in the malt: but keep out about half a bushel dry, which you are to strew over the rest, when you have done stirring it, which will be as soon as you have well mixed it with the liquor, and prevented it from clodding.
After the dry malt is laid on, cover your mash tub with cloths, to prevent losing any spirit of the malt, and let it so remain for two hours. Meanwhile have another copper of liquor hot; and at two hours end begin to let off your first wort into the under-back. Receive a pailful of the first running, and throw it again upon the malt.--You will find that the malt has sucked up half of your first copper of liquor; and therefore to make up your quantity of wort for your strong beer, you must gradually lade out of the second copper, and strew bowl after bowl over the malt, giving it time to soak thro', and keeping it running by an easy stream, till you perceive you have about forty gallons, which in boiling and working will be reduced to thirty-six.
If you throw into the under-back (whilst you are letting off) about half a pound of hops, it will preserve it from foxing, or growing sour or ropy.
Your first wort being all run off, you must soften the tap of the mash tub; and take a copper of hot liquor for your second mashing, stirring up the malt as you did at first, and then cover it close for two hours more. Meanwhile you fill your copper with the first wort, and boil it with the remainder of the two pounds of hops, for an hour and an half, and then lade it off into the coolers.
