Heating by electricity.-In treating beer, wine, and other liquids in bottles to bring them into condition for use, the bottles are immersed in a bath of water or other liquid which is heated by electric means. A vessel a of wood or other non-conductor, containing racks f to support the bottles, is fitted at the bottom with a plate c of copper, carbon, iron, or other conductor supported on insulating- bars d. A second plate g is attached to the cover, and a current is passed between the plates. The plates may be heated by electro-magnets, through which an alternating current is passed, placed below the lower plate. Electro-magnets may be placed also above the vessel to act in conjunction with the lower magnets. Hollow plates containing electric resistances may be used to heat the liquid.
