When you’re out and about, there’s nothing quite like a Starbucks drink to brighten your day. But what happens when you find yourself with leftover coffee or tea in a Starbucks plastic cup and you’re tempted to reheat it in the microwave? This brings up an important question: Can you put Starbucks plastic cups in the microwave? To answer this question, we will delve into the types of plastics used in these cups, the potential risks involved, and some safer alternatives for reheating your favorite beverages.
Understanding Starbucks Plastic Cups
Starbucks uses a variety of plastic cups for their drinks, predominantly made from polypropylene (#5 plastic) and PET (#1 plastic).
Types of Plastics Used
Polypropylene (PP): This plastic is often used for hot beverage cups because it has a high melting point and good heat resistance. While it is generally considered microwave-safe, not all products made from this material are designed for repeated heating.
Polyethylene Terephthalate (PET): Commonly used for cold drinks, PET is not recommended for microwaving. It has a lower melting point and can degrade when exposed to high temperatures.
Starbucks’ Labeling and Guidelines
Starbucks often labels its cups for safe use, but it’s important to remain vigilant. Some reusable plastic cups may carry a label designating them as microwave-safe, while others may not have clear instructions. Always check for specific heating guidelines on the cup itself.
The Risks of Microwaving Starbucks Cups
Before placing a Starbucks plastic cup in the microwave, consider the following risks:

2. Reusable Cups
On the other hand, Starbucks’ reusable plastic cups are often microwave-safe, but this varies per product. Check the markings on the bottom of your reusable cup before microwaving. If it features a microwave icon, you’re generally in the clear.
Best Practices for Reheating Beverages
If you’ve determined that your Starbucks cup is not microwave-safe, here are some best practices for reheating your beverages while ensuring safety.
1. Transfer to Microwave-Safe Containers
The simplest solution is to transfer your beverage to a microwave-safe container. Look for glass or ceramic mugs that are specifically labeled as microwave-safe, as they can withstand higher temperatures without risk.
2. Stirring Before Heating
If you decide to use a microwave, stir your drink before and midway through heating to ensure even warmth throughout the beverage. This also helps to prevent the formation of hot spots that can scald your mouth.
3. Covering the Container
Using a microwave-safe lid or a piece of microwave-safe parchment paper can help prevent spills. Always leave a small gap for steam to escape.
Alternatives to Reheating Starbucks Drinks
If you frequently find yourself with leftover drinks and don’t want to rely on microwaving plastic, consider the following alternatives to enjoy your coffee or tea later.
1. Cold Brewing
For iced coffee enthusiasts, consider cold brewing instead of reheating. This method produces a smooth, less acidic flavor, and you can store it in the fridge for several days.
2. Making Small Batches
Another effective method is simply to make smaller drinks. If you’re unlikely to finish an entire beverage, consider ordering a smaller size or buying a coffee pod system at home for fresh brews.
Conclusion
In conclusion, when pondering the question, Can you put Starbucks plastic cups in the microwave? the answer is nuanced. While certain reusable cups may be microwave-safe, the risk of chemical leaching, structural changes, and safety hazards makes it wiser to choose alternative containers for reheating.
Learning to handle your Starbucks cups safely will enhance your coffee experience rather than detract from it. Remember to prioritize your safety and well-being by investing in high-quality, microwave-safe containers for your beverages. With these precautions in mind, you can enjoy your favorite Starbucks drinks without worry.
