Blackberry Wine.
1. LET your berries be full ripe when you gather them for this purpose. Put them into a large vessel either of wood or stone, with a cock in it, and pour upon them as much boiling water as will cover them. As soon as the heat will permit you to put your hand into the vessel, bruise them well till all the berries are broken. Then let them stand covered till the berries begin to rise towards the top, which they will do in three or four days. Then draw off the clear into another vessel, and add to every ten quarts of this liquor one pound of sugar. Stir it well in, and let it stand to work, a week or ten days, in another vessel like the first. Then draw it off at the cork through a jelly-bag into a large vessel. Take four ounces of isinglass, and lay it to steep twelve hours in a pint of white wine. The next morning, boil it upon a slow fire till it is all dissolved. Then take a gallon of your blackberry juice, put in the dissolved isinglass, give them a boil together, and pour all into the vessel. Let it stand a few days to purge and settle, then draw it off, and keep it in a cool place.
