Whether you like to call them, carboy or demijohn or jimmy john, they all refer to the same glass containers. Carboy originates from the Persian word; qarabah. Demijohn comes from the French; dame-Jeanne, or Lady Jane and derives from the 17th century and refers to any glass vessel, with a large body, capable of holding from 5 and 16 gallons of liquid, with a small neck and presumably encased in wicker. In England, demijohn refers to an imperial gallon, used for the fermentation process in brewing. **Top reads "VIRESA" and belly reads "15-LTS" ***Please note chipped mouth (images 5 & 6) and a crack at the bottom (images 17 & 18).
