Copper cups have enjoyed a resurgence in popularity, gracing bars, restaurants, and homes alike. Their aesthetic appeal, purported health benefits, and ability to keep drinks icy cold contribute to their allure. But what exactly should you be drinking out of a copper cup? The answer is more nuanced than you might think, and understanding the considerations is crucial for both safety and optimal enjoyment.
The Allure of Copper: More Than Just Aesthetics
Copper’s visual appeal is undeniable. The warm, reddish-brown hue adds a touch of rustic elegance to any drink presentation. Beyond aesthetics, copper possesses properties that enhance the drinking experience. It’s a superb conductor of heat, which means it rapidly cools down liquids and maintains that temperature, keeping your drink refreshingly cold for longer.
The history of copper drinkware extends back centuries. Ancient civilizations utilized copper for its antimicrobial properties, believing it kept water cleaner and safer to drink. While modern water treatment methods render this aspect less critical, the historical connection adds to the mystique surrounding copper cups.
The Moscow Mule and Beyond: Iconic Copper Cup Cocktails
The drink most famously associated with copper cups is undoubtedly the Moscow Mule. This simple yet satisfying cocktail, consisting of vodka, ginger beer, and lime juice, found its perfect partner in the copper mug. The cool touch of the copper accentuated the refreshing qualities of the drink, creating a sensory experience that has captivated drinkers for decades.
While the Moscow Mule reigns supreme, numerous other cocktails benefit from being served in copper. Any drink designed to be refreshingly cold, such as a Mint Julep, Dark ‘n’ Stormy, or even a simple Gin and Tonic, can be elevated by the chill-enhancing properties of copper.
Consider cocktails with strong citrus notes. The acidity interacts with the copper, potentially enhancing the overall flavor profile, though this is a subtle effect and depends greatly on the specific cocktail and the quality of the copper.
Safety First: Understanding Copper’s Reactivity
While copper offers several advantages, it’s crucial to be aware of its reactivity with acidic substances. Copper is, to a degree, toxic if ingested in large quantities. The interior lining of a copper mug is therefore critically important.
The Importance of Linings: Many commercially available copper mugs are lined with stainless steel or nickel. These linings act as a barrier, preventing direct contact between the acidic drink and the copper, thereby mitigating the risk of copper leaching into the beverage. If your copper mug is lined, you have a wider range of drink options.
Unlined Copper: A Word of Caution: Unlined copper mugs pose a greater risk. Acidic drinks, like fruit juices or cocktails with citrus, can cause copper to leach into the liquid. Over time, this can lead to copper poisoning, which can manifest in symptoms such as nausea, vomiting, and abdominal pain. Therefore, unlined copper mugs should only be used for water or drinks with a neutral pH.
Checking for Linings: Carefully inspect your copper mugs before use. Look for a distinct seam or a different color on the interior surface. If you’re unsure, it’s always best to err on the side of caution and only use the mug for water.
Ideal Drinks for Copper Cups: A Detailed Breakdown
Assuming your copper cup is lined with a safe material like stainless steel, here’s a more comprehensive list of drinks that are well-suited for copper mugs:
Cocktails: As mentioned earlier, the Moscow Mule is the quintessential copper cup cocktail. But the possibilities extend far beyond. Drinks like Margaritas, Mojitos, and other citrus-based cocktails can be incredibly refreshing when served in copper. Experiment with different recipes and find your personal favorites. Remember to adjust the sweetness to compensate for any potential reaction between the citrus and the copper.
Beers: Certain beers, particularly those with lighter profiles and crisp finishes, can benefit from the cool temperature that copper provides. Pilsners, lagers, and wheat beers are good choices. The copper can help maintain the beer’s effervescence and enhance its refreshing qualities. Avoid pouring dark or heavy beers into copper cups, as the subtle nuances of these beers can be lost in the temperature shift.
Non-Alcoholic Beverages: Copper cups aren’t just for alcoholic drinks. Iced tea, lemonade, ginger ale, and even sparkling water can be elevated by the cool touch of copper. The visual appeal of the copper also makes these drinks more enjoyable, especially when serving guests. Infused waters, with cucumber, mint, or berries, are a fantastic choice for showcasing the aesthetic of a copper mug.
Water: While the antimicrobial benefits of copper are less relevant with treated water, drinking water from a copper cup can still be a pleasant experience. The cool temperature and unique taste (though subtle) can make staying hydrated more enjoyable. Some proponents of Ayurveda believe that storing water in a copper vessel overnight has health benefits, but scientific evidence supporting these claims is limited.
Drinks to Avoid in Copper Cups: Playing it Safe
Regardless of claims about copper’s health benefits, caution should always be exercised. Acidic liquids, particularly in unlined copper, should be avoided to prevent copper leaching.
Fruit Juices: Orange juice, grapefruit juice, pineapple juice, and other acidic fruit juices should not be consumed from unlined copper cups. The high acidity levels can cause significant copper leaching, potentially leading to health problems. Even in lined cups, prolonged exposure to highly acidic juices might not be ideal, so limit the contact time.
Wine: Wine, especially red wine, contains tannins and acids that can react with copper. This interaction can alter the taste of the wine, making it metallic or unpleasant. Additionally, the acidity can cause copper leaching. It’s best to stick to traditional glassware for wine.
Vinegar-Based Drinks: Drinks containing vinegar, such as shrubs or certain cocktails, should also be avoided in unlined copper cups. Vinegar is highly acidic and will readily react with the copper.
Carbonated Beverages with High Acidity: Although some carbonated beverages are fine in copper cups, those with high acidity, like certain colas or sour sodas, should be treated with caution, especially if the cup is unlined.
Caring for Your Copper Cups: Maintenance and Longevity
Proper care is essential to maintain the beauty and integrity of your copper cups.
Cleaning: Hand washing is recommended for copper cups. Avoid using abrasive cleaners or scouring pads, as these can scratch the surface and damage the finish. Use a mild dish soap and warm water. For stubborn stains, a paste of baking soda and water can be gently applied.
Tarnish: Copper naturally tarnishes over time, developing a patina. Some people find this patina appealing, while others prefer the bright, shiny look of polished copper. To remove tarnish, you can use commercial copper cleaners or a homemade solution of lemon juice and salt. Apply the cleaner gently, rinse thoroughly, and dry immediately.
Storage: When not in use, store your copper cups in a dry place. This will help prevent tarnish and corrosion. Avoid stacking them directly on top of each other, as this can scratch the surface.
Copper Alternatives: Exploring Other Drinkware Options
While copper cups offer a unique drinking experience, several alternatives provide similar benefits without the potential risks.
Stainless Steel: Stainless steel is a safe, durable, and easy-to-maintain material for drinkware. It doesn’t react with acidic beverages and can keep drinks cold for a long time. Stainless steel cups are also widely available and relatively inexpensive.
Glass: Glass is a classic and versatile choice for drinkware. It’s inert, meaning it doesn’t react with beverages, and it allows you to see the drink clearly. Glassware comes in a wide variety of shapes and sizes, making it suitable for any type of drink.
Insulated Tumblers: Insulated tumblers, often made of stainless steel or plastic with a vacuum-sealed design, are excellent for keeping drinks cold or hot for extended periods. These tumblers are ideal for outdoor activities or for keeping drinks at the desired temperature throughout the day.
The Verdict: Enjoying Copper Cups Responsibly
Copper cups can be a delightful addition to your drinkware collection. Their aesthetic appeal and ability to keep drinks cold make them a popular choice for cocktails and other refreshing beverages. However, it’s crucial to be aware of the potential risks associated with copper reactivity.
Always choose copper cups that are lined with a safe material like stainless steel. Avoid using unlined copper cups for acidic drinks. Practice proper care and maintenance to ensure the longevity of your cups. And most importantly, enjoy your drinks responsibly!
By understanding the nuances of copper drinkware, you can make informed decisions and enjoy the benefits of copper cups without compromising your health. So, go ahead and enjoy that Moscow Mule, but do so with knowledge and care.
FAQ 1: What are the purported health benefits of drinking from a copper cup?
Drinking from copper cups is often associated with traditional Ayurvedic practices that claim copper has antibacterial, antiviral, and anti-inflammatory properties. Supporters believe that storing water in a copper vessel allows the water to absorb trace amounts of copper, which can then help boost the immune system, improve digestion, and promote healthy skin. However, it’s important to note that these claims are largely based on anecdotal evidence and traditional beliefs.
While copper is an essential trace mineral, the amount absorbed from a copper cup is typically very small. Scientific evidence supporting the health benefits specifically from drinking from copper cups is limited. It’s crucial to maintain a balanced and skeptical perspective and consult with a healthcare professional regarding any health concerns or decisions.
FAQ 2: What types of beverages are best suited for copper mugs?
Copper mugs are traditionally associated with serving Moscow Mules, a cocktail made with vodka, ginger beer, and lime juice.
