Do you enjoy a frosty Moscow Mule in one of those iconic Copper Mugs?
Well you better check to make sure the inside of the copper cup is lined. Copper and copper alloy are poisonous when the ph level (acidity) gets to 6.0 or below. And yes you beloved Moscow Mule has a ph level well below 6.0.
Many state and federal regulations ban the use of copper when in contact with food and beverages. Examples of low ph foods and drinks are wine, fruit juice, lemons, limes, vinegar, and many mixed cocktails.High concentrations of copper are poisonous and have caused foodborne illness. When copper and copper alloy surfaces contact acidic foods, copper may be leached into the food. It is important to remember that if the inside of the copper cup if lined for example with metal such as stainless steel or nickle the cup is safe for use.
If your copper cup is not lined. DO NOT USE it for drinks or food. We recommend making it into a small flower pot. Make sure to check with your bartender or server to make sure the cups being used are lined. The popularity of the Moscow Mule has lead to a mass import of poor quality products that may be hazardous to your health.
