Thomas Chapman The Cyder-Maker's Instructor, Sweet-Maker's Assistant…

There is what is called a fret, which is only a partial fermentation, that nature is strong enough in some liquors to bring on, without the assistance of art; but this fret, or partial fermentation, is never strong enough to discharge the liquor of its foul parts; and if they should ever happen to subside, the least alteration in weather, as well as a hundred other accidents, will occasion their commixing, and render the liquor almost, or altogether as foul as ever; to prevent which we call in the assistance of art, and which our method will effectually prevent.

It is very seldom that the fruit is all of the same goodness, I would therefore recommend, that the best fruit be made separate from the ordinary, it being easy, and much more prudent, to mix the liquors to your palate, than to run the hazard of making the good fruit with the bad, a small quantity of which will sometimes spoil the flavour of the liquor, and turn it acid.

In brewing beer, yest is apply'd to it, in order to ferment it, without which it would never be beer. This opens the body of the liquor, and renders it spirity and fine.
The reason that cyder is not often fine, is owing to its not being fermented. After it is got into the hogshead, the generality of people think they have acquitted themselves very well, and done all the necessary business, except racking it. But I can assure them, the more any liquor is rack'd, the more it is weaken'd. By often racking, it loseth its body, and so becomes acid for want of strength to support it.
