Can you use copper mugs for coffee?

In this article, we will answer the question “Can you use copper mugs for coffee?” and discuss the effects of copper mugs on coffee.

Can you use copper mugs for coffee?

Yes,  you can use copper mugs for coffee. Moscow mules have a pH of 5.0, according to a recent Iowa Alcoholic Beverages Division notice, and copper should not be used in anything that has a pH of 5.0 or below.

When ingested along with the beverage, the metal in a Moscow mule may leach into food and induce unpleasant symptoms including diarrhea, vomiting, and stomach pains. This can happen to anybody who consumes the cocktail.

A metal cup will become hot or cold depending on what’s in it, so use caution while drinking hot liquids. To get copper poisoning, you’d have to let the liquid sit in the copper mug for very some time. The Iowa study’s publicity was exaggerated. Furthermore, the interior of most copper mugs isn’t even made of copper since they are lined.

If the copper mug’s inside is coated with a non-reactive metal like stainless steel, tin, or nickel, you may use it for coffee. Coffee’s acidity dissolves copper ions, which gives it a metallic flavor. Copper poisoning is possible if you eat or drink much of it.

Most individuals pay close attention to every step of the coffee-brewing process, from purchasing the finest tools and equipment to using the best coffee beans and filtered water. However, the sort of cup we use for coffee receives little consideration.

While some coffee connoisseurs have a particular cup, the majority of people are content with whichever mug they happen to be using.

Our houses are frequently stocked with a variety of drinkware: glassware, ceramics, metallic and plastic travel mugs, and for some, Moscow Mule mugs. Drinking coffee from copper cups has always been fraught with controversy.

Copper mugs after being filled with coffee

In Iowa, copper and copper alloys should not be exposed to meals with a pH of less than six because of the increased danger of copper ingestion when it dissolves in acidic foods and beverages.

To avoid copper leaching into drinks, the advice suggests using copper mugs coated with nickel or stainless steel.

When oxygen reacts with copper (II), an oxide is formed. Copper reacts and dissolves in acids, which is critical. Coffee’s acidity (pH ranges from 4.85 to 5.13) puts it at danger of copper leaching, which may taint the taste.

Others believe that the interactions between acidic beverages and unlined copper mugs are unlikely to release toxic amounts of copper.. Researchers believe that very high acidity and prolonged contact time are required in order to seriously damage copper mugs at levels that endanger human health.

n spite of this, you could prefer lined copper mugs since the interaction between copper and coffee produces a metallic taste in your coffee. There are several sought-after flavours in coffee that are mild and easily obscured by other tastes, despite coffee’s strong fragrance. Coffee’s taste is one of its most important features.

What Is the Reason for the Use of Copper Cups?

The Moscow Mule, a Vodka drink popularised in the United States during the 1940s, paired well with copper mugs.

According to legend, three entrepreneurs struggling to sell their respective goods (Vodka, ginger beer, and copper mugs) created a drink using Vodka and ginger beer served in copper mugs to help boost sales of their combined products.

Copper cups were perfect for serving the drink since they kept it warm while also bringing out the flavours. It was such popular, copper mugs were dubbed Moscow Mule mugs as a result of the combo.

Water sterilization has been suggested by some in connection with unlined copper mugs that have been connected to antibacterial advantages.

However, despite studies showing that copper and copper alloys are effective in preventing the spread of germs in medical settings, little is known about copper’s capacity to destroy bacteria in water. But keeping cold water in copper mugs helps to keep it colder for a longer time.

Is It Okay To Drink From Copper Mugs?

It’s OK to use unlined copper mugs with non-acidic beverages since the metal won’t react with them. Coffee, tea, vinegar, and fruit juices should all be served in ceramic or glass mugs that have been lined with copper to prevent the contents from staining the copper. Copper isn’t the best material for coffee cups, in my opinion.

To keep you safe as well as the taste of your beverage, most copper tumblers and travel mugs contain stainless steel or nickel inside lining that you can buy separately. Turks use copper-lined lead-free tin ibriks for their coffee, an example of which may be found here. Turkish coffee is brewed in an ibrik, which is a pot.
