There are a variety of methods in managing liquors whilst they are working.—Some people beat the yeast of strong beer and ale, once in two or three hours, for two or three days together.
This they reckon makes the drink more heady, but withal hardens it so as to be drinkable in two or three days; the last day of beating it in, (stirring the yeast and beer together) the yeast, as it rises, will thicken; and then they take off part of the yeast, and beat in the rest, which they repeat as often as it rises thick; and when it has done working, they tun it up, so as it may just work out of the barrel.
Others again do not beat it in at all, but let their strong drink work about two days, or till they see the ferment is over; and then they take off the top yeast, and either by a tap near the bottom, let it off sine, or else lade it out gently, to leave the sediment and yeast at the bottom.
This way is proper for liquor that is to be drank soon: but if it be to keep, it will want the sediment to feed upon, and may probably grow stale, unless you make artificial lees: This you may make of a quart of brandy, and as much flour of wheat as will make it into dough; put them in lumps into the bung hole as soon as it has done working. Or else take a pound of the powder of oyster shells and mix it with a pound of treacle or honey, and put it in soon after it has done working.
It would add to the goodness, as well as sining of your malt liquor, if you took two quarts of wheat, and make them very dry and crisp in an oven, or before the fire, and boil them in your first copper of wort.—They would strain off with your hops, and might be put with them into the second copper.
Of the fining of Malt Liquors.
It is most desirable to have beer fine of itself, which it seldom fails to do in due time, if rightly brewed and worked; but as disappointments some times happen, it will be necessary to know what to do in such cases.
Ivory shavings boiled in your wort, or hartshorn shavings put into your cask just before you bung it down, will do much towards fining and keeping your liquor from growing stale.
Isinglass is the most common thing made use of in fining all sorts of liquors; they first beat it well with a hammer or mallet, and lay it in a pail, and then draw off about two gallons of the liquor to be fined upon it, and let it soak two or three days; and when it is soft enough to mix with the liquor, they take a whisk, and stir it about till it is all of a ferment, and white froth; and they frequently add the whites and shells of about a dozen of eggs, which they beat in with it, and put altogether into the cask; then with a clean mop-stick, or some such thing, stir the whole together; and then lay a cloth, or piece of paper over the bung-hole, till the ferment is over; and then bung it up close, in a few days it will fall fine.
But if you want to fine only a small quantity, take half an ounce of unflacked lime, and put it into a pint of water, and stir it well together, and let it stand for two or three hours, or till the lime settle to the bottom; then pour the water off clear, and throw away the sediment; then take half an ounce of isinglass cut small, and boil it in the lime water till it dissolves; then let it cool, and pour it into the vessel, &c.
