Copper mugs can be safely used to serve Moscow mules if they are lined with a non-reactive metal
Copper mugs have a certain allure, and the famous Moscow Mule cocktail is traditionally served in one. However, in recent years, concerns have been raised about the safety of drinking from copper mugs, with some articles claiming that copper can leach into drinks, leading to copper poisoning.
While it is true that copper mugs can be unsafe if used incorrectly, the risk of copper poisoning is minimal if common-sense practices are followed. Firstly, it is important to note that most commercial copper mugs are lined with food-safe materials like stainless steel, nickel, or tin to prevent leaching. These mugs can safely be used to serve Moscow mules.
Secondly, while pure copper can react with acidic liquids, leading to potential overexposure to copper, this is only a concern if the mug is unlined, and the cocktail is left in the mug for an extended period. The risk of copper leaching increases with the acidity of the liquid and the length of time the liquid is in contact with copper. To avoid this, it is recommended that drinks are served immediately and that customers are discouraged from leaving beverages in copper mugs for more than two hours.
Additionally, while copper mugs can add a unique aesthetic to cocktails like the Moscow Mule, proper handling is essential to ensure their safe use. It is recommended to avoid highly acidic drinks in unlined copper mugs, as these can accelerate copper leaching. Instead, opt for drinks with moderate acidity or use lined copper mugs for added safety.
In conclusion, while the risk of copper poisoning from a Moscow Mule served in a copper mug is low, it is important to follow best practices to ensure the safe use of these iconic drinking vessels.

The Iowa Alcoholic Beverage Division issued an advisory bulletin in July 2017, notifying the public that Iowa would no longer serve cocktails in unlined copper mugs
In July 2017, the Iowa Alcoholic Beverage Division issued an advisory bulletin notifying the public that Iowa would no longer serve cocktails in unlined copper mugs. This decision was made in accordance with the FDA's suggestion that copper should not come into direct contact with foods or beverages with a pH level below 6.0. The FDA's Model Food Code, which Iowa and many other states have adopted, prohibits this due to the risk of copper leaching into such substances, which can cause foodborne illness if consumed in high concentrations.
The pH level of a traditional Moscow Mule, an alcoholic cocktail typically served in a copper mug, is well below 6.0. This is because of the lime juice and ginger beer, which both have a pH lower than 6. As a result, Iowa's bulletin stated that copper mugs with a copper interior may not be used to serve this beverage.
The bulletin also aimed to address the recent popularity of Moscow Mules and the inquiries regarding the safe use of copper mugs with this cocktail. While copper mugs are generally safe to drink from, there are some concerns when serving acidic drinks, which can lead to potential overexposure to copper. Most commercial copper mugs today are lined with food-safe materials like stainless steel or nickel to prevent leaching.
To ensure the safe use of copper mugs, it is recommended to avoid leaving drinks in the mugs for extended periods, as prolonged contact between liquids and copper increases the risk of leaching. It is also advised to avoid using copper mugs for hot beverages, as heat accelerates copper leaching, especially in unlined cups. Proper cleaning and maintenance of copper mugs are also crucial to preserving their lining and ensuring drink safety.

The FDA prohibits food with a pH less than 6.0 from coming into direct contact with copper and copper alloys
Copper mugs have become increasingly popular, especially for serving cocktails like the Moscow Mule. However, concerns have been raised about the potential health risks associated with using copper mugs for beverages.
The primary concern is the possibility of copper leaching into the drink, which can occur when acidic liquids come into contact with copper. The more acidic the liquid, the higher the risk of copper leaching. Liquids with a pH below 6.0, such as alcohol, fruit juices, and vinegar, are more likely to cause copper leaching. As a result, the FDA prohibits food or drinks with a pH less than 6.0 from coming into direct contact with copper and copper alloys like brass. This is because direct contact with copper under these conditions can increase the risk of copper toxicity.
To address this concern, many modern copper mugs are lined with food-safe materials like stainless steel, nickel, or tin to prevent direct contact between the copper and the beverage. These linings act as a barrier, reducing the risk of copper leaching into the drink. Additionally, proper handling and maintenance of copper mugs are crucial. It is recommended to avoid letting drinks sit in copper mugs for extended periods, as prolonged contact can increase the risk of copper leaching.
While the risk of copper toxicity from an occasional Moscow Mule served in a copper mug is low, excessive long-term exposure to copper can have adverse effects. These effects may include gastrointestinal issues such as nausea and diarrhoea, as well as neurological problems like dizziness and headaches. However, it is important to note that achieving toxic levels of copper ingestion through occasional cocktail consumption is unlikely, and proper use and care of copper mugs can further minimise any potential risks.
In summary, while the aesthetic appeal of serving cocktails in copper mugs is undeniable, it is essential to prioritise safety by using lined copper mugs, avoiding highly acidic drinks, and preventing prolonged contact between the beverage and the copper mug. By following these guidelines, consumers can minimise any potential health risks associated with copper mugs while still enjoying their unique aesthetic and sensory experience.
