After the Mojito and the Spritz, the new trend this summer is the Moscow Mule, served in a copper mug. But it seems that this cocktail can be the cause of food poisoning. We explain why.
The Moscow Mule at the origin of food poisoning
The Moscow Mule, this cocktail made with vodka, ginger beer and lime juice is the must of this summer. Its particularity is to be served in a copper cup, which acts as a flavor enhancer, increasing the number of beer bubbles and keeping it fresh. But this drink could poison you.
In a newsletter dated July 28, 2017, the Alcoholic Beverages Division of Iowa, USA expressed concern about the consequences of the mixture. Experts warn that copper should not come into contact with acidic foods with a pH below 6, such as wine, vinegar or citrus fruits. However, the pH of the Moscow Mule is much lower than this figure.
Copper poisoning can have serious consequences
Questioned by the daily The Independent, the American experts explain that a ” High copper concentration can be toxic and can cause food poisoning. Indeed, when copper or copper alloy surfaces come into contact with acidic products, food or liquids can absorb them. “. Copper poisoning can cause abdominal pain, diarrhea or vomiting and, in severe cases, liver failure..
You can therefore continue to drink your favorite cocktail, as long as it is not in contact with the copper. Before the first sip, check that the mug in which it is served is lined inside another metal (usually nickel or stainless steel). In American bars, the solution is more radical: they have removed the cocktail from their cards!
