Beer is one of the worlds' oldest beverages, possibly dating back to 6th millennium BCE, and is recorded in the written history of Ancient Egypt and Mesopotamia.[4] The earliest known chemical evidence of beer dates to circa 3500–3100 BCE.[5] As almost any substance containing carbohydrates, namely sugar or starch, can naturally undergo fermentation, it is likely that beer-like beverages were independently invented among various cultures throughout the world.
A beer stein or Steinkrug is a traditionally German beer tankard or beaker, made of glass, pewter, silver, wood, porcelain, earthenware, or stoneware.
