Tracing the History of Copper as a Drinking Vessel

The use of copper for drinking vessels is not a modern phenomenon. Its history stretches back thousands of years, with evidence of copper cups found in various ancient civilizations. In ancient Ireland, a copper goblet known as an escra was used. Yogis in India also traditionally used copper cups, a practice known as Tamara Jal, which involved storing water in copper vessels. American colonists also utilized copper mugs, with examples like the Virginia tankard dating back to the 17th century.

The Moscow Mule and the Copper Mug

The association of the copper mug with the Moscow Mule cocktail is a more recent, yet highly influential, development. The story goes that in the 1940s, a collaboration between a distributor with an excess of vodka, a producer with a surplus of ginger beer, and an immigrant with a large inventory of copper mugs led to the creation and popularization of the Moscow Mule served in its now-iconic copper vessel. The copper mug is believed to enhance the experience by keeping the drink exceptionally cold.

Exploring the Potential Health Benefits of Copper Cups

Advocates for drinking from copper cups often point to a range of potential health benefits. These claims are rooted in both traditional practices, such as Ayurveda, and some modern scientific understanding of copper's properties. However, it's important to note that while copper is an essential trace mineral for human health, the extent to which drinking from a copper cup contributes to these benefits is a subject of ongoing discussion and varying scientific opinions.

Antimicrobial Properties

One of the most frequently cited benefits is copper's natural antimicrobial property. Studies have shown that copper surfaces can kill harmful bacteria, viruses, and fungi. Storing water in a copper vessel for a period of time is believed by some to purify the water by reducing microbial contamination.

Digestive Health

In Ayurvedic tradition, drinking water stored in copper vessels in the morning on an empty stomach is believed to aid digestion. Some sources suggest copper helps stimulate peristalsis, the contraction and relaxation of stomach muscles, which assists in the movement of waste through the intestines. Copper is also thought to help break down fats and proteins.

Immune System Support and Antioxidant Effects

Copper is an essential mineral that plays a role in maintaining the immune system. Additionally, copper is a powerful antioxidant that helps neutralize free radicals in the body. Free radicals are unstable molecules that can damage cells and contribute to chronic diseases and the aging process. By helping to combat oxidative stress, copper is believed to potentially reduce the risk of certain ailments.

Other Reported Benefits

Beyond the commonly cited benefits, proponents also suggest that drinking from copper cups may help regulate thyroid function, reduce inflammation, support weight loss, and improve skin health by aiding in the production of collagen and elastin. Copper's role in melanin production is also highlighted for its potential to protect the skin from sun damage.

Scientific Perspective and Considerations

While the historical use and anecdotal evidence for the benefits of copper cups are prevalent, it's important to consider the scientific perspective. Some experts argue that while copper is essential, the amount leached into water from a cup may be minimal and that a balanced diet is the primary way to ensure adequate copper intake. There is also a potential risk of copper toxicity if excessive amounts of copper are ingested, although this is generally considered unlikely with typical use of copper cups for neutral beverages.

Here's a summary of some of the claimed benefits and considerations:

Claimed Benefit	Potential Mechanism / Traditional Belief	Scientific Consensus / Consideration
Antimicrobial Properties	Copper surfaces kill bacteria, viruses, and fungi.	Copper does have antimicrobial properties; the extent of water purification in a cup can vary.
Improved Digestion	Stimulates peristalsis, helps break down food (Ayurvedic belief).	Limited direct scientific evidence linking copper cup use to significant digestive improvement.
Boosted Immunity	Copper is essential for immune system function.	Adequate dietary copper is important for immunity; contribution from cup may be minor.
Antioxidant Effects	Copper neutralizes free radicals.	Copper is an antioxidant; dietary intake is the primary source.
Reduced Inflammation	Believed to have anti-inflammatory properties.	Research is ongoing; direct link from copper cup use is not firmly established.
Improved Skin Health	Aids collagen and elastin production, melanin synthesis.	Copper is involved in these processes; systemic intake is key.
Regulated Thyroid Function	Traditional belief.	Limited scientific evidence.
Weight Loss Support	Traditional belief.	Limited scientific evidence.
Reduced Cancer Risk	Some research on copper compounds showing anti-cancer potential.	This is an area of ongoing research and not directly linked to drinking from a copper cup.

Important Considerations for Usage

When using copper cups, particularly those that are unlined, it is generally advised to avoid acidic beverages like citrus juices, vinegar, or soda. Acidic liquids can potentially leach higher amounts of copper from the cup. For these types of drinks, lined copper cups (often with tin or stainless steel) are recommended. Regular cleaning is also important to prevent the buildup of tarnish and ensure hygiene. Hand washing with mild soap and water is typically recommended, and it's important to dry the cups thoroughly to prevent spotting.

Beyond the Moscow Mule: Other Uses for Copper Cups

While the Moscow Mule is the most famous occupant of the copper mug, these versatile vessels can be used for a variety of other beverages. Their ability to retain cold temperatures makes them ideal for any iced drink.

Cold Beverages

Copper cups are excellent for keeping drinks cold for extended periods. This makes them suitable for iced tea, cold brew coffee, smoothies, and even just plain water, especially on a hot day. The cold metal exterior also provides a refreshing tactile experience.

Other Cocktails

Besides the Moscow Mule, other cocktails that benefit from being served cold can be enjoyed in a copper cup. The Julep cup, often made of copper, is the traditional vessel for a Mint Julep. Other iced cocktails could also be served in copper mugs.
