If the rumor that it may not be safe to drink from your Moscow Mule mug is giving you pause, hear us out. While it’s true that the State of Iowa Alcoholic Beverages Division issued an advisory saying, “copper and copper alloys such as brass may not be used in contact with a food that has a pH below 6 such as vinegar, fruit juice, or wine”, the fact of the matter is that it’s what on the inside that counts. After all, let’s not forget that many beers are brewed in copper tanks and liquors distilled in copper stills.

Although the the pH of a traditional Moscow Mule may well be below the advisory’s recommended level of 6.0., which could cause a reaction between the cocktail’s acidic ingredients and the mug’s metal, there is a simple solution: to know if your glass is safe to drink from, choose a Moscow Mule mug lined with a non-reactive material, such as stainless steel.

And just as it’s important to invest in a quality bottle of vodka, so to you should you stock up on proper (pH-friendly) Moscow mule mugs.
