They're Gallon Jars, really very cool, great condition, AND CHEAP! lol
I'm going to be using them for Brewing Cider, and maybe more depending on how well that goes!!! Never brewed before, so it's all an experience!!
I also obtained this (see attached) from the guy I bought the Demijohns off of. It's around 3ft tall and is shaped into a Woman holding a drinking vessel on her head...pretty cool too (especially for £5), NO IDEA what the hell I'm gonna use that for?! Suggestions?!
