Carefully examine the stein to find identifying marks. Look for incised marks impressed into the clay as the stein dried or ink marks stamped on the stein afterwards. Check the back of the handle if the bottom of the stein doesn't have a mark.

Beer stein types include earthenware, porcelain, creamware pottery, saltglazed stoneware and glass. Examine the stein to determine the overall theme of the images etched into the stein body. For example, earthenware steins typically feature images of everyday life, hunting or group celebrations. Porcelain steins, which are hand painted and more delicate than earthenware steins, typically feature nature scenes with gold and silver decorations.
