Key Takeaways
- Melting Point Matters: Polystyrene, the material of red solo cups, starts melting at 212-248°F. Coffee brewed hotter than 194°F can deform the cup and release harmful chemicals like benzene1.
- Optimal Coffee Temperatures: The sweet spot for brewing coffee is 195-205°F, and the best sipping temperature ranges from 120-175°F.
- Health Risks Alert: Hot coffee in a solo cup can leach toxic plasticizers, posing cancer and immune system risks.
- Manufacturer Guidelines: Solo cups are specifically intended for cold beverages only, as per manufacturer guidelines2.
- Alternative Solutions: Insulated cups, mugs, tumblers, or compostable cups are safer choices for hot beverages.
Can You Put Hot Coffee in a Red Solo Cup?
No, you should not put hot coffee in a Red Solo Cup. Here are clear reasons why:
- Melting Risk: Red Solo Cups are made of plastic which can melt or deform when exposed to high temperatures, like that of hot coffee.
- Chemical Leaching: The heat from the coffee can cause the plastic to leach chemicals into your drink, which is not only unhealthy but can also alter the taste of the coffee.
- Safety Concern: The cup can become too hot to hold, leading to potential spills and burns.
- Structural Integrity: The cup may weaken with the heat, increasing the risk of it breaking and spilling the contents.
Now that we’ve gotten that clear answer out of the way, let’s dig a bit more into the reasons why it’s not a good idea to drink hot coffee out of a solo cup.
What Material Are Red Solo Cups Made Of?
Red Solo Cups are ubiquitous in parties, picnics, and casual gatherings. But have you ever wondered what they’re made of? Understanding the material composition of Red Solo Cups is crucial for safe and proper use.
Material Composition
Red Solo Cups are made from polystyrene, also known as #6 plastic. This material starts to soften and eventually melt at temperatures ranging between 100-120°C (212-248°F). It’s essential to note that Solo, the company that manufactures these cups, specifically advises against using them for hot liquids or microwaving them.
Health Risks
When subjected to heat, polystyrene releases benzene, a chemical compound that poses significant health risks, including cancer. Scientific research supports these concerns (Source).
Key Takeaways
- Red Solo Cups are made of polystyrene (#6 plastic).
- The material softens and melts between 100-120°C (212-248°F).
- Not suitable for hot liquids or microwave use due to health risks associated with benzene release.
The Science of Coffee Temperature: Why It’s Too Hot for a Red Solo Cup
Navigating the ideal temperatures for both brewing and drinking coffee is an art backed by science. But before diving into the specifics, it’s crucial to highlight that freshly brewed coffee is far too hot for materials like polystyrene—the substance Red Solo Cups are made of.
With coffee brewing at 195-205°F (90-96°C), and Red Solo Cups melting at 212-248°F (100-120°C), there’s a narrow margin for error. Consuming hot coffee from a Red Solo Cup could risk not only a bad coffee experience but also exposure to harmful chemicals.
Brewing Temperature:
Aim for a brewing temperature range of 195-205°F (90-96°C) for optimal extraction. This range has been universally acknowledged as the perfect balance for extracting essential flavors and oils from your coffee grounds.
Drinking Temperature:
For the best flavor experience, your coffee should be enjoyed at a temperature ranging from 120-175°F (49-79°C). In this window, coffee delivers its fullest range of flavors and aromas. Below 120°F, the coffee flavors shift, revealing more sweetness and acidity.
Hot Coffee and Red Solo Cups: A Mismatch
Freshly brewed coffee can reach temperatures of 195-205°F (90-96°C), which is dangerously close to the softening and melting point of a Red Solo Cup. This poses not only a risk of melting the cup but also the release of hazardous chemicals like benzene.
Key Takeaways
- Brewing temperature for coffee should be between 195-205°F (90-96°C).
- Optimal drinking temperature is 120-175°F (49-79°C).
- Freshly brewed coffee is too hot for a Red Solo Cup due to the risk of melting and chemical release.
The Hidden Dangers of Using Red Solo Cups for Hot Coffee: What You Need to Know
Pouring hot coffee into a Red Solo Cup is more than just a taste faux pas—it’s a practice laden with serious health, safety, and environmental risks. If you’re someone who is diligent about what goes into your coffee, it’s just as important to know what your coffee could be going into. Let’s explore the data-backed reasons why using Red Solo Cups for hot beverages is a bad idea.
1. Serious Health Risks
Red Solo Cups are typically made from Polystyrene and PVC, materials containing an array of harmful chemicals. These chemicals, including Benzene, BPA (Bisphenol A), and Styrene, can leach into hot liquids like coffee, posing risks of cancer, hormonal imbalances, and immune system damage.
The heat significantly accelerates this chemical leaching, making hot beverages particularly risky (Source 1, Source 2). A study in the journal Science of the Total Environment found that bisphenol A exposure was significantly higher when drinking coffee from plastic cups as opposed to glass ones (Source).
2. Risk of Expansion and Breakage
The material composition of Red Solo Cups makes them susceptible to expansion when exposed to hot liquids. This can cause the cup to lose its shape, or worse, crack and spill its contents. The risk is not only messy but also hazardous if it leads to hot coffee spills.
3. Recycling & Environmental Impact
Polystyrene, the primary material in Red Solo Cups, poses significant recycling challenges. It takes up to 450 years for these cups to decompose, meaning they contribute to long-term landfill waste and soil pollution. The environmental implications extend to the leaching of toxic substances into the soil, posing further dangers to wildlife and human health.
Smart Alternatives to Using Red Solo Cups for Hot Coffee: A Practical Guide
Understanding the hazards of using Red Solo Cups for hot coffee naturally leads to the question: What are the best alternatives? Below are actionable recommendations that prioritize both your health and environmental sustainability.

FAQ
Can I microwave a red solo cup?
No, manufacturer guidelines state they are not for hot liquids or microwave use. If you have to reheat coffee in a solo cup, use a low microwave setting and minimize time to reduce chemical leaching.
What temperature does a red solo cup melt?
The melting point of a Red Solo Cup ranges between 212-248°F (100-120°C). These cups start to soften and eventually melt when exposed to temperatures within this range, making them unsuitable for hot beverages like coffee, which is often brewed at temperatures close to the cup’s melting point.
What’s the safe temperature to drink coffee from a red solo cup?
It’s not recommended to drink hot coffee from a Red Solo Cup due to health risks. The cups soften and potentially melt at 212-248°F, close to coffee’s typical brewing temperature of 195-205°F, posing risks of chemical leaching.
