This size jug is very handy for doing 6lb meads. However, the spigot was not installed, and no instructions on how to tighten the nut inside the jug since the opening is too narrow for one's hand, and too deep for any conventional tool. Using various long lengths of wood, I was able to put enough pressure against the nut inside to effectively tighten the spigot so the seal wouldn't leak. Also the description does not mention the size of stopper needed for holding an airlock.
