BREWING MACHINE. Where a family usually consume ten gallons of beer, or upwards, in a week, there is a Brewing Machine lately invented, which will be found singularly convenient and advantageous, and comparatively of little expense. The use of it in brewing curtails the labour, shortens the time in which the operation may be performed, greatly diminishes the quantity of fuel, and may be placed within very narrow limits, in the house of any tradesman in the most crowded city. Eighteen gallons of good beer may be brewed with this machine in the course of six hours, or a larger quantity with a machine of proportionate dimensions, in the same space of time. The process is so simple, that it may be comprehended by any person of ordinary capacity, and once seeing the operation performed will be sufficient. In the common mode of brewing, the principal difficulty consists in ascertaining the degrees of heat necessary to the production of good beer, without the use of a thermometer; but in the use of this machine, this difficulty is completely obviated.--The machine complete is represented by figure A; and B, C, D, E, F, represent its several parts. B is the bottom, made of strong sheet-iron, standing upon three legs. The hollow part of it contains the fire, put in at a door, the latch of which appears in front. The tube which projects upwards, is a stove pipe to carry off the smoke; and the circular pan that is seen between the legs, is a receptacle for the ashes or cinders that fall down through the grate above. C is a sheet-iron vessel, tinned on the inside, the bottom of which fits into the top of B; and the cock in C is to let off the wort, as will be seen hereafter. D is the lid of this vessel. E is made of sheet-iron, tinned inside and out, and full of holes to act as a strainer. It is to hold the malt first, and the hops afterwards; it goes into C, as may be seen in figure A. In the middle of E is a round space, F, made of the same metal, and rising up from the bottom, having itself no bottom. It has holes in it all the way up, like the outer surface of E.--In preparing for brewing, the machine is put together as in A, except placing on the lid. The first thing is to put the malt, coarsely ground, into E, and no part into F, or into the circular space between C and E; otherwise E cannot act as a strainer, when the liquor is drawn off; and in this consists its principal use. Having put in the malt, then add the water which of course flows into any part of the vessel C. Stir the malt well with a stick, or with something that will separate it completely, so that no adhesion may be formed by the flour of the malt. This is very apt to be the case in the common mode of brewing, when water is poured hot upon the malt; but here the water is applied in a cold state, so that there is little trouble in separating the malt completely in the water. If the small machine be used, which is adapted
