Have you ever wondered what a beer Stein is? It's an English description of a tankard from Germany.
In German "stein" means stone, but in English, a stein has come to be known as a drinking vessel designed to contain beer.
Historically a German stein would most typically have had a lid attached. Historically it was believed this was necessary to keep out the "bad air" that was thought to carry the plague in the 14th Century. They could be made of many things including glass, pewter or stoneware (Steinzeug), but we've never known one to be made of leather.
We handmake our traditional British leather tankards on the high Pennines of England. It's a lovely old tradition to keep alive in a beautiful rural setting.
