41. There are two descriptions of persons whom I am desirous to see brewing their own beer; namely, _tradesmen_, and _labourers_ and _journeymen_. There must, therefore, be two _distinct scales_ treated of. In the former editions of this work, I spoke of a _machine_ for brewing, and stated the advantages of using it in a family of any considerable consumption of beer; but, while, from my desire to promote _private brewing_, I strongly recommended the _machine_, I stated that, "if any of my readers could point out any method by which we should be more likely to restore the practice of private brewing, and especially to the _cottage_, I should be greatly obliged to them to communicate it to me." Such communications have been made, and I am very happy to be able, in this new edition of my little work, to avail myself of them. There was, in the _Patent Machine_, always, an objection on account of the _expense_; for, even the machine for _one bushel of malt_ cost, at the reduced price, _eight pounds_; a sum far above the reach of _a cottager_, and even above that of a small tradesman. Its _convenience_, especially in _towns_, where room is so valuable, was an object of great importance; but there were _disadvantages_ attending it which, until after some experience, I did not ascertain. It will be remembered that the method by the brewing machine requires the malt to be put into _the cold water_, and for the water to make the malt _swim_, or, at least, to be in such proportion as to prevent the fire beneath from burning the malt. We found that our beer was _flat_, and that it did _not keep_. And this arose, I have every reason to believe, from this process. The malt should be put _into hot water_, and the water, at first, should be but just sufficient in quantity to _stir the malt in_, and _separate it well_. Nevertheless, when it is merely to make _small beer_; beer _not wanted to keep_; in such cases the brewing machine may be of use; and, as will be seen by-and-by, a moveable _boiler_ (which has nothing to do with the _patent_) may, in many cases, be of great convenience and utility.
