Nice find! I'm not sure I'd consider that a primitive ginger beer, I think it's a bit late and a bit more sophisticated for that. It is older than your average UK ginger beer though, though I'm not sure exactly what era it dates to. 1870s would be my guess but I could be wrong. Interesting that it's got the name of the pottery company and not the bottler. I wonder if it was brought here on a ship or if these were ever used in Montreal by a local firm.
thank's guys.Really nice looking bottle.
