Observations on Yeast.
That yeast is the main spring in distilling, is acknowledged by all distillers, tho' but few if them understand it, either in its nature or operation; tho' many pretend a knowledge of the grand subject of fermentation, and affect to understand the best mode of making stock yeast, and to know a secret mode unknown to all others—when it is my belief they know very little about it; but, by holding out the idea of adding some drug, not to be procured at every house, which has a hard name, and that is little known to people of common capacities: Such as Dragons blood, &c. frequently retailing their secret, as the best possible mode of making stock yeast, at ten, twenty, and in some[Pg 26] instances one hundred dollars.
Confessing it a subject, abstruse, and a science little understood in Pennsylvania, and notwithstanding the numerous experiments I have made with care and close observation, yet from a consciousness of not understanding it, too well, I have in several instances purchased receipts, and made faithful experiments; but have never yet met the man of science, theory, or practice, whose mode of making stock yeast, yielded a better preparation for promoting fermentation, than the simple mode pursued by myself for some years, and which I have uniformly found to be the best and most productive.
In making yeast, all drugs and witchcraft are unnecessary—Cleanliness, in preserving the vessels perfectly sweet, good malt, and hops, and an industrious distiller, capable of observation, and attention to the following receipt, which will be assuredly found to contain the essence and spirit of the ways and art of making that composition, a knowledge of which I have acquired, by purchases—consultations with the most eminent brewers, bakers, and distillers in this commonwealth, and above all, from a long practice and experience, proving its utility and superior merits to my most perfect satisfaction; and which I with[Pg 27] pleasure offer to my fellow-citizens, as meriting a preference—notwithstanding the proud and scientific chymist, and the flowery declarations or treatises of the profound theorist, may disapprove this simple mode, and offer those which they presume to be better, tho' they never soiled a finger in making a practical experiment, or perhaps witnessed a process of any description.
