Introduction
Many people ask, Can You Microwave Carbonated Drinks? The short answer is that you should generally avoid doing it, especially with sealed containers. Carbonated drinks such as soda, sparkling water, beer, cider, and kombucha contain dissolved carbon dioxide gas. When that liquid is heated, the gas becomes less soluble and pressure can build quickly. In a microwave, heating is also uneven, which increases the chance of sudden fizzing, boiling over, or container failure. A sealed can or bottle can rupture violently, while an open cup can spray hot liquid and cause burns. This guide explains the risks, safer alternatives, practical tips, common mistakes, and what to do if an accident happens.

What Are Carbonated Drinks?
Carbonated drinks are beverages that contain dissolved carbon dioxide. The carbon dioxide is usually introduced under pressure during manufacturing or fermentation. When the container is opened, some gas escapes as bubbles, but much of it remains dissolved in the liquid. The amount of dissolved gas depends on temperature, pressure, and the composition of the drink. Colder liquid holds more carbon dioxide, while warmer liquid holds less. This is one reason a cold soda may taste crisp and a warm soda may taste flat.
Common carbonated drinks include cola, lemon-lime soda, ginger ale, tonic water, sparkling water, seltzer, beer, hard cider, sparkling wine, and kombucha. Some are highly carbonated, while others have only mild fizz. Sugar, alcohol, acids, flavorings, and minerals can also affect how the liquid behaves when heated. A sugary soda may become sticky and scorch more easily, while an alcoholic beverage may produce stronger odors and flavor changes when warmed.
Can You Microwave Carbonated Drinks?
The safest practical answer to Can You Microwave Carbonated Drinks? is no, not as a routine way to warm them. The risk is not just that the drink may lose fizz. The bigger concern is pressure, sudden bubbling, and uneven heating. A microwave heats water molecules throughout the liquid, but it does not heat every area equally. Some pockets can become much hotter than others. In a carbonated liquid, those hot pockets can trigger rapid bubble formation, causing the drink to surge upward or spray out of the container.
If the container is sealed, the situation is much more dangerous. A sealed can or bottle has no safe vent for expanding gas. As temperature rises, internal pressure rises. The container can bulge, leak, burst, or explode. This can damage the microwave, create a mess, and cause serious burns or eye injuries. Even if nothing explodes, the drink may become unpleasantly hot in spots and lose most of its carbonation.
If the drink is open and you use extreme caution, it may be possible to warm a small amount slightly, but it is still not recommended. Safer methods are usually just as convenient and produce better results.
Why Microwaving Carbonated Drinks Is Risky
The risk comes from several factors working together. First, carbon dioxide is less soluble at higher temperatures. As the drink warms, gas comes out of solution and forms bubbles. Second, microwave heating can create localized hot spots. Third, steam and expanding gas increase pressure inside any container that is not fully open. Fourth, many common containers are not safe for microwave use or are not designed to hold hot liquid.
These factors can turn a simple warming attempt into a messy or dangerous event. A drink that looks calm can suddenly foam over when you open the microwave door or move the cup. Hot carbonated liquid can also cling to surfaces and cause burns that are worse than burns from water because sugar and acid may irritate skin.
Pressure Buildup and Container Failure
Pressure is the most serious hazard. In a sealed can, the liquid and gas are trapped in a rigid metal container. As the microwave adds heat, the liquid expands slightly, dissolved carbon dioxide comes out of solution, and any water vapor adds more gas. The internal pressure can exceed the strength of the can. The can may bulge at the ends, seams may split, or the top may blow off. The result can be a loud pop, a spray of hot liquid, and sharp metal fragments.
Glass bottles are also dangerous when sealed. Glass can shatter under pressure or thermal stress. Plastic bottles may deform, melt, or leak before bursting. Even containers that seem sturdy are not designed for microwave heating. A bottle cap can become a projectile. A can may not look damaged until it fails suddenly.
Open containers reduce pressure risk but do not eliminate it. A narrow glass with little headspace can still foam over. A drink that has been shaken or recently opened may release gas more aggressively. If the container is nearly full, there is nowhere for foam to go except over the rim.
Uneven Heating and Hot Spots
Microwaves do not heat liquids in a perfectly uniform way. Standing waves create zones of stronger and weaker energy. The center of a cup may be cooler while the edges become very hot. In a carbonated drink, hot spots can cause localized boiling or sudden bubble release. Because carbonated liquid has many tiny nucleation sites, bubbles can form rapidly once a hot spot crosses a certain temperature.
This means the surface temperature may feel acceptable while deeper liquid is much hotter. Stirring helps, but stirring a hot carbonated drink can also trigger foaming. If you stir too vigorously, you may release a large amount of gas at once. The safest approach is to avoid microwaving the drink in the first place, especially if you need it for a child, an older adult, or anyone with sensitive skin.
Container Types and Safety
The container matters as much as the drink. Metal cans should never go in a microwave. Sealed glass bottles should never go in a microwave. Plastic bottles may soften, warp, or release unwanted chemicals when heated. Paper cups are not ideal for hot liquid and may leak. Styrofoam can melt or deform. Even microwave-safe ceramic mugs can become dangerously hot if filled too full.
| Container or Drink State | Microwave Safety | Main Concern |
|---|---|---|
| Sealed aluminum can | Never | Pressure buildup and possible explosion |
| Sealed glass bottle | Never | Pressure, cracking, and shattering |
| Sealed plastic bottle | Never | Deformation, leaks, and pressure |
| Open glass with little headspace | Not recommended | Foaming over and hot spots |
| Open microwave-safe mug with large headspace | Possible with caution | Sudden fizzing and uneven heating |
| Flat soda in a microwave-safe mug | Generally safer | Hot spots and sticky residue |
If you are unsure whether a container is microwave-safe, do not use it. Look for a microwave-safe symbol or use a known ceramic or glass mug. Avoid metal rims, decorative metallic paint, and containers with cracks or chips. (See Also:How Long Do You Microwave Pizza Rolls)
Step-by-Step: If You Must Warm a Carbonated Drink
This process is not a recommendation to microwave carbonated drinks regularly. It is a damage-control approach for situations where a small amount of gentle warming is truly necessary. If you can let the drink go flat or use a warm water bath instead, choose that method.
- Pour the drink into a large, clean, microwave-safe mug or bowl, leaving at least one third of the container empty for foam.
- Remove any cap, lid, straw, or metal object from the container.
- Let the drink sit for a few minutes so some carbonation can escape naturally.
- Use a low power setting, such as 30 to 50 percent, rather than full power.
- Heat for only 10 to 15 seconds at a time.
- Remove the container carefully and look for fizzing or swelling before touching it.
- Stir very gently with a long spoon to distribute heat.
- Check the temperature before drinking or serving.
- Stop immediately if the drink foams, hisses, or rises.
- Let the drink stand briefly so hot spots can even out.
Even with these steps, the drink may lose carbonation and flavor. If it begins to foam, do not return it to the microwave. Let it settle, allow it to cool slightly, and consider discarding it if it has become too hot or messy.
Safer Alternatives to Microwaving
The best alternative depends on why you want the drink warm. If you want a warm beverage, consider starting with a non-carbonated drink such as tea, coffee, hot chocolate, or warm juice. If you need to warm a carbonated drink for a recipe or personal preference, use a gentler method.
A warm water bath is one of the safest options. Place the open drink in a heatproof container, then set that container in a bowl of warm water. Avoid boiling water because it can heat the drink too quickly and cause foaming. Stir gently and monitor the temperature. This method warms the liquid gradually and reduces hot spots.
Another option is to let the drink go flat first. Pour it into a wide glass and wait. As carbonation escapes, the drink becomes much safer to warm. You can then microwave it like an ordinary sugary liquid, using short intervals and stirring. Flat soda is less likely to foam, but it can still become very hot.
You can also simply let the drink reach room temperature. Many carbonated beverages taste better slightly chilled than hot, and room temperature may be enough for comfort. For mixed drinks, adding a small amount of warm water or warm juice can raise the temperature without heating the carbonated portion directly.
Comparison of Warming Methods
Different warming methods have different trade-offs. The table below compares common approaches for carbonated drinks.
| Method | Speed | Safety Level | Effect on Carbonation | Best Use |
|---|---|---|---|---|
| Microwave on high power | Fast | Low | Strong loss and possible overflow | Not recommended |
| Microwave on low power in short bursts | Moderate | Moderate with caution | Moderate loss | Small amounts of open drink |
| Warm water bath | Slow to moderate | High | Gradual loss | Gentle warming of open drinks |
| Room temperature resting | Slow | High | Some loss | Everyday drinking |
| Letting drink go flat, then microwaving | Moderate | Moderate to high | Most carbonation lost | Recipes or flat soda |
For most people, the best choice is to avoid heating carbonated drinks at all. If warmth is important, a non-carbonated alternative or a carefully managed warm water bath is usually the better option.
Tips and Best Practices
- Never microwave a sealed can, bottle, or any container with a tight lid.
- Use a container that is much larger than the amount of liquid.
- Keep the power level low and the heating time short.
- Watch the drink through the microwave door instead of walking away.
- Do not shake, stir aggressively, or tap the container before heating.
- Keep your face and hands away from the container when opening the microwave.
- Test the temperature carefully before serving.
- Use a towel or oven mitt when handling a warm mug.
- Clean spills immediately so sugar does not become sticky or attract pests.
- If the drink is for a child, avoid microwaving it and choose a safer beverage.
These tips reduce risk but do not make microwaving carbonated drinks completely safe. A drink that foams unexpectedly can still cause burns. If you notice pressure, swelling, or unusual sounds, stop and let the container cool.
Common Mistakes and How to Avoid Them
One common mistake is assuming that an open container is automatically safe. An open cup can still foam over, especially if it is nearly full or freshly opened. Leaving plenty of headspace and using low power helps, but it does not remove all risk.
Another mistake is microwaving a can because it seems quick. This is one of the most dangerous errors. A sealed can has no safe release for expanding gas. Even a short heating time can cause bulging or rupture. Never do this, even if the can feels only slightly warm afterward.
People also often microwave a drink after shaking it. Shaking adds extra carbon dioxide bubbles and increases the chance of a sudden eruption. If the drink has been shaken, let it settle before doing anything else, and preferably do not heat it.
Using full power is another frequent problem. High power heats too quickly and creates hot spots. Short bursts at low power give you more control. Finally, many people forget that the container itself can become hot. A mug that feels manageable on the outside may contain liquid that is much hotter.
Special Cases: Soda, Sparkling Water, Beer, and More
Soda is one of the most common drinks people try to warm. Because it contains sugar, caffeine in many cases, and strong flavoring, heating can change its taste and make it sticky. Diet soda may not have sugar, but it still contains carbon dioxide and can foam or spray. The absence of sugar does not make it safe to microwave in a sealed container.

Sparkling water usually has fewer ingredients, but it is still carbonated. It can foam when heated and may taste flat afterward. Flavored sparkling water may contain acids or oils that react to heat in unpredictable ways.
Beer is carbonated and contains alcohol. Microwaving beer is generally a bad idea. It can foam violently, develop off flavors, and produce a strong smell. The alcohol content is usually too low to create a fire hazard in a normal microwave, but heating alcohol-containing beverages can concentrate aroma and may be unpleasant or unsafe if handled carelessly.
Kombucha contains living cultures and acids. Heating it may kill beneficial microbes and alter its flavor. Sparkling wine and champagne are highly pressurized and should never be microwaved. Their bottles and corks can create serious hazards. Energy drinks often contain caffeine, sugar, and other additives, and heating them does not make them safer or more effective.
Cleanup and Safety After Spills or Explosions
If a carbonated drink spills in the microwave, turn off the appliance and unplug it if you can do so safely. Wait for the interior to cool before cleaning. Hot liquid and steam can cause burns. Open the door carefully and keep your face back. If a can or bottle ruptured, inspect the microwave for sharp fragments before wiping it down.
Use a soft cloth, warm water, and mild dish soap to clean sticky residue. Avoid abrasive pads that can scratch the interior. Pay attention to the door seal, turntable, and vents. If sugar has caramelized, place a bowl of warm water in the microwave for a short time to soften residue, then wipe again. Do not run the microwave with large chunks of debris inside.
If you suspect damage to the microwave, stop using it until it is inspected. A ruptured can may dent the interior or damage the door. If you smell burning plastic or see sparks, unplug the appliance and contact a qualified repair professional. When in doubt, safety is more important than convenience.
Frequently Asked Questions
Can you microwave a can of soda?
No. A sealed can should never be microwaved. Expanding gas and rising pressure can cause the can to bulge, leak, or explode. This can damage the microwave and cause serious burns or injuries.
Is it safe to microwave carbonated water?
It is not recommended. Even without sugar, carbonated water contains dissolved carbon dioxide that can form bubbles and foam when heated. If you choose to do it, use an open microwave-safe container, low power, short intervals, and plenty of headspace.
Does microwaving remove carbonation?
Heating generally reduces carbonation because carbon dioxide becomes less soluble at higher temperatures. However, it does not remove carbonation instantly or predictably. Some gas may remain and release suddenly when the drink is moved or opened. (See Also:Are Rubbermaid Takealongs Microwave Safe)
Can microwaving soda cause an explosion?
Yes, especially in a sealed container. In an open container, the more likely result is foaming, spraying, or boiling over. Both situations can cause burns and a difficult cleanup.
Can you microwave beer?
It is not recommended. Beer is carbonated and contains alcohol, so it can foam and develop unpleasant flavors. It is safer to use a warm water bath or choose a non-carbonated warm beverage.
What should you do if soda spills in the microwave?
Turn off the microwave, let it cool, and open the door carefully. Wipe the interior with warm soapy water. If a container ruptured, check for sharp pieces and inspect the appliance for damage before using it again.
Can you microwave flat soda?
Yes, flat soda can usually be microwaved more safely than carbonated soda because it is less likely to foam. Use a microwave-safe container, heat in short intervals, stir gently, and watch for hot spots.
Can you warm sparkling water to make tea?
It is better to use still water. Sparkling water can foam, taste flat, and heat unevenly. If you only have sparkling water, let it go flat first or use a warm water bath rather than microwaving it directly.
Conclusion
The answer to Can You Microwave Carbonated Drinks? is that you should generally avoid it. Carbonated beverages contain dissolved gas that becomes less stable when heated, and microwave heating is uneven. Sealed containers can rupture, while open containers can foam over and spray hot liquid. If you need a warm drink, safer choices include room temperature beverages, warm water baths, or letting the drink go flat before gentle heating. When in doubt, choose a non-carbonated alternative and keep your microwave, your kitchen, and yourself safe.
