 Recently, Iowa's Alcoholic Beverages Division issued an advisory stating that pure copper mugs should not be used to serve Moscow mules or other acidic beverages with a pH below 6.0, including fruit juices, vinegar and wine. Traditionally, Moscow mules contain vodka, ginger beer and lime and have a pH well below 6.0, the advisory said. 
 
 When copper comes into contact with acidic foods and beverages, copper may leach into the food or drink. Ingesting too much copper can lead to copper poisoning, the advisory said. Symptoms of copper poisoning include abdominal pain, diarrhea, vomiting and jaundice, or a yellowing of the skin, according to the National Institutes of Health.

 The Alcoholic Beverages Division said it issued the advisory because of the recent rise in popularity of Moscow mules, which has led to questions about the safety of copper containers for this beverage. 
 
 But Moscow mule enthusiasts need not despair — you can still use a mug with a copper exterior, as long as the interior is lined with a different metal, such as nickel or stainless steel. Mugs with these interiors are safe containers for the cocktail, and are widely available, the advisory said.

– One of the most talked-about cocktails this week is the trendy Moscow Mule, but for all the wrong reasons. You can thank Iowa. The spate of headlines was kicked off by an official state health advisory warning that the drink, usually served in a copper mug, poses a health risk if the wrong kind of mug is used. For the uninitiated, a Moscow Mule has vodka, ginger beer, and lime, and thus is acidic, explains Live Science. The problem is, you're not supposed to serve acidic beverages in mugs with a copper interior because it raises the risk of copper leaching into the drink. Solution? A mug with a copper exterior is fine, but make sure the interior is made of stainless steel, nickel, or some other alternative. The advice isn't new, but the state felt compelled to issue the advisory given the "recent popularity of Moscow Mules." (A cruise through Instagram proves the point.) Iowa's warning is based on an FDA advisory from a few years ago. Specifically, it says that drinks with a PH level of 6.0 or under should not be served in pure copper mugs, and the Mule falls into that category. For the record, so do fruit juices, vinegar, and wine, notes the Daily News. (Some might prefer a little food poisoning to this cocktail ingredient.)
