“A mixture of meal and water, with the addition of yeast or such remains of a former fermentation as adhere to the sides or bottom of the vessel, and exposure to a temperature between sixty-eight and seventy-seven degrees Fahrenheit, will produce immediate fermentation. In this process there are five stages: the saccharine, by which the starch and gum of the vegetables, in their natural condition, are converted into sugar; the vinous, which changes the sugar into alcohol; the mucilaginous, sometimes taking the place of the vinous, and occurring where the sugar solution, or fermenting principle, is weak, producing a slimy, glutinous product; the acetic, forming vinegar, from the vinous or alcoholic stage; and the putrefactive, which destroys all the nutritive principles and converts them into a poison. The precise points in fermentation, when the food becomes most profitable for feeding, has not as yet been satisfactorily determined; but that it should stop short of the putrefactive, and probably the full maturity of the acetic, is certain.”
