ebulum

Take a hogshead of the first and strong wort, and boil in the same one bushel of picked Elderberries, full ripe; strain off, and when cold, work the liquor in the hogshead, and not in an open tun or tub; and after it has lain in the cask about a year, bottle it; and it will be a good rich drink, which they call ebulum; and has often been preferred to portwine, for its pleasant taste, and healthful quality.
