Title: "Heavy cast metal" is NOT Stainless Steel!
Review: Others have noted that this item discolors in the dishwasher. The reason for this is that the "heavy cast metal" is not Stainless Steel but "pot metal." There is no scientific metallurgical standard for pot metal; common metals in pot metal include zinc, lead, copper, tin, magnesium, aluminium, iron, and cadmium. Many of these metals will react with the very hot alkaline water in a dishwasher; the reason they discolor is that some of the metal has been dissolved. Since the manufacturer does not state which metals are used, and my opinion is that it is best to avoid possible exposure to lead, tin and cadmium, I would not use this product for beverage production.
