Neither do men put new wine into old bottles: else the bottles break, and the wine runs out, and the bottles perish…
As soon as the animal (goat) is killed, an opening is made in the skin large enough to introduce the lips, and a man begins to blow between the skin and the flesh until the two are completely separated from each other throughout. The head and feet are then cut off, and the entire body of the animal is drawn out of its skin through the opening at the neck. The hair is sometimes partially removed and the skin tanned. In Persia the skins are saturated with pitch. The opening at the neck is used for filling and emptying the vessel, while the four feet are tied or sewed up. The grape-juice which is to undergo the process of fermentation is put into skins, which are either entirely new or which have been carefully examined and found able to withstand the pressure.
