Thomas Chapman, The Cyder-Maker's Instructor, Sweet-Maker's Assistant…
“ When it comes to a stiff jelly, beat it well in your can with a whisk, and mix some of the cyder with it, 'till you have made the gallon four; then put two pounds of brick rubbings to it, and stir it together with two gallons of cyder more added to it, and apply to the hogshead; stir it well with your paddle, and shive it up close. The next day give it vent, and you will find it fine and bright. If you force perry, cut your isinglass with cyder or stale beer, for no liquor will force its own body. ”
