BREWING UTENSILS. The most desirable object in the process of brewing is the fixing of the copper, so as to make the fire come directly under the bottom of it. Many coppers are injured, and rendered unserviceable, for want of proper attention to this particular. The method adopted by the most experienced bricklayers is to divide the heat of the fire by a stop; and if the door and the draft be in a direct line, the stop must be erected from the middle of each outline of the grating, and parallel with the centre sides of the copper. The stop is nothing more than a thin wall in the centre of the right and left sides of the copper, ascending half way to the top of it; on the top of which must be left a small cavity, four or five inches square, for a draft of that half part of the fire which is next to the copper door, to pass through, and then the building must close all round to the finishing at the top. By this method of fixing the copper, the heat will communicate from the outward part of the fire round the outward half of the copper through the cavity; as also will the furthest part of the fire, which contracts a conjunction of the whole, and causes the flame to slide gently and equally all round the bottom of the copper. Considerable advantages result from this position of the copper. If the draught under it were suffered at once to ascend, without being thus divided, the hops would be scorched in the boiling, and liable to stick to the sides, which would considerably injure the flavour of the liquor, unless kept continually stirring. It will also save the consumption of fuel, and preserve the copper much longer than any other method, as there will be no difficulty in boiling half a copper full at a time without doing it any injury.--The next article of consideration in this case is the Mash-tub. This should be proportioned to the size of the copper, and the quantity of beer intended to be brewed. The grains should not be kept in the tub any longer than the day after brewing, as in hot weather especially the grains begin to turn sour as soon as they are cold; and if there be any sour scent in the brewhouse at the time the liquor is tunned, it will be apt to injure the flavour of the beer.--Tubs and Coolers require to be kept perfectly sweet and clean, and should not be used for any other purpose. In small houses, where many vessels are cumbersome and inconvenient, it is too common to use the same tubs for both washing and brewing; but this ought not to be done where it can be avoided; and where it is unavoidable, the utmost care is necessary to give them a double washing, scouring, and scalding. Coolers also require considerable care, or by the slightest taint they will soon contract a disagreeable flavour. This often proceeds from wet having infused itself into the wood, it being apt to lodge in the crevices of old vessels, and even infect them to such a degree, that it cannot be removed, even after several washings and scaldings.
