How to get rid of carbonation in a canned drink?

6 min read

According to chemists, carbonation is a result of carbon dioxide dissolved in water under pressure, which escapes once a container is opened. For those who prefer a less fizzy beverage, knowing how to get rid of carbonation in a canned drink is a useful and easy skill to master. Whether for personal preference or to avoid the gassy feeling, there are several simple techniques you can use.

Quick Summary

This guide details effective ways to reduce fizziness in a canned beverage, from gentle agitation to temperature manipulation. Learn which methods work best for different levels of decarbonation and flavor preservation.

Key Points

  • Aggressive Pour: Pouring a canned drink into a glass from a high position releases carbonation quickly by increasing surface area and agitation.

  • Temperature Manipulation: Warming a drink, such as in a microwave or saucepan, causes dissolved carbon dioxide to escape more rapidly.

  • Add a Catalyst: A small amount of sugar or salt provides nucleation sites, triggering a fast and dramatic release of carbon dioxide.

  • Vigorous Agitation: Stirring the drink rapidly with a spoon is a straightforward way to release carbonation and reduce fizz.

  • Patience Prevails: Leaving a can open for an extended period is the simplest method for decarbonation, relying on the natural process of gas escaping from the liquid.

  • Use a Paper Towel: A folded paper towel placed in the drink acts as a concentrated source of nucleation sites, drawing out carbonation effectively without affecting flavor.

Understanding the Science of Fizz

Before diving into the methods, it's helpful to understand the science behind what makes your drink fizzy. Carbonated beverages are infused with carbon dioxide ($CO_2$) gas under high pressure. When you open the can, the pressure is released, and the $CO_2$ gas escapes, forming the bubbles you see and feel. The rate at which this gas escapes is influenced by several factors, including temperature and agitation. The goal of any decarbonation method is to accelerate this process safely.

The Simplest Approaches

For a quick and easy reduction in fizz, start with these low-tech methods.

  • The Aggressive Pour: This is one of the most common ways to release carbonation quickly. Pour the beverage into a glass from a high position, allowing it to splash vigorously. The increased surface area and turbulence created during the pour will cause much of the dissolved $CO_2$ to escape. Repeat this process by pouring the liquid back and forth between two glasses for maximum effect.

  • Vigorous Stirring: Once the drink is in a glass, use a spoon or stir stick to mix it rapidly. The agitation will cause the $CO_2$ to release from the solution, creating a lot of initial bubbles that will quickly subside. Continue stirring until the desired level of flatness is achieved.

  • The Paper Towel Trick: For a surprisingly effective method, take a clean, folded paper towel and dip one end into your drink, allowing it to hang out over the side of the glass. The towel's fibers provide numerous nucleation sites for bubbles to form and escape, effectively drawing the carbonation out of the liquid.

Using Temperature to Your Advantage

Changing the temperature of your drink can also affect its carbonation level. The colder a liquid is, the more gas it can hold in solution. Therefore, warming your drink will cause the gas to escape more readily.

  • Stovetop Simmer: This is an extreme but highly effective method for quickly getting a completely flat beverage. Pour the drink into a saucepan and heat it gently over medium-low heat, stirring constantly. Do not bring it to a boil, as this can alter the flavor significantly. The rising temperature will cause the carbon dioxide to leave the solution rapidly. Allow the drink to cool completely before consuming.

  • Microwave Magic: For a faster version of the warming method, pour the drink into a microwave-safe mug. Heat it in short bursts of 15-20 seconds, stirring in between. This will create enough heat to release the gas without boiling the liquid.

Creative and Effective Methods

Beyond the basics, there are a few other clever ways to tackle carbonation.

  • Use a Milk Frother: A battery-operated milk frother can be used to agitate the drink aggressively. Placing it in the can or a glass and turning it on for a few seconds will create a large foam head, releasing the carbon dioxide. Be prepared for a rapid and messy reaction.

  • Add a Catalyst: Certain ingredients can act as a catalyst for carbonation release. A tiny pinch of salt or a small amount of sugar added to the drink can cause a dramatic release of gas. This is because the particles provide nucleation sites for the bubbles to form. Be careful, as this will cause a vigorous fizz and can alter the taste.

Comparison of Carbonation Reduction Methods

Method Speed Effect on Flavor Mess Factor Best For
Aggressive Pour Fast Minor dilution, minimal change High Quick, on-the-go decarbonation without tools.
Vigorous Stirring Medium No change (if unflavored tool is used) Medium Reducing fizz in a glass to a controlled degree.
Paper Towel Trick Slow No change Low A very gentle, hands-off approach.
Stovetop Simmer Very Fast High potential for flavor alteration Low Creating a completely flat, non-fizzy beverage.
Add Sugar/Salt Very Fast Changes flavor profile Very High Rapid deflation where flavor change is acceptable.
Milk Frother Very Fast No change Very High Maximum fizz removal in a short time.

Conclusion

From simple pouring techniques to more involved methods using temperature or catalysts, there are multiple effective ways to get rid of carbonation in a canned drink. The best method depends on your desired speed and whether you want to preserve the original flavor. For a quick reduction in fizz without much effort, an aggressive pour is your best bet. If you need a completely flat drink and don't mind a slight flavor change, the stovetop simmer is highly effective. By understanding the principles of gas solubility, you can choose the right technique to enjoy your drink exactly how you like it.

Key Takeaways

  • Agitation is Key: Shaking or stirring a canned drink forces dissolved $CO_2$ gas to escape from the liquid, rapidly decreasing its carbonation.
  • Temperature Affects Solubility: The warmer a beverage is, the less dissolved carbon dioxide it can hold, making it go flat faster when heated gently.
  • Increase Surface Area for Faster Results: Methods like pouring into a wide glass or using a large object like a spoon increase the liquid's surface area, which helps speed up the release of $CO_2$.
  • Catalysts Accelerate Gas Release: Adding a small amount of salt or sugar provides nucleation sites that cause a quick and dramatic release of carbon dioxide bubbles.
  • Pouring Technique Matters: Pouring a carbonated drink from a high position or between glasses maximizes agitation and surface area, quickly reducing fizz.
  • Patience is a Method: Simply leaving the can open and letting the drink sit will naturally reduce carbonation over time, though it is the slowest approach.

FAQs

Q: Will stirring a can of soda with a spoon make it less fizzy? A: Yes, stirring a can of soda with a spoon will cause the carbon dioxide to be released, making it less fizzy. The agitation provides nucleation sites for the gas to escape.

Q: Does adding ice cubes to a canned drink reduce carbonation? A: Adding ice cubes does reduce carbonation, primarily by providing nucleation sites on their surface for the dissolved gas to escape. However, since cold temperatures help retain carbonation, this effect is somewhat counteracted.

Q: What is the fastest way to get rid of carbonation in a can? A: The fastest way is to combine an aggressive pour into a wide glass with vigorous stirring. For a near-instant effect, adding a small amount of salt or sugar will also work, though it may change the flavor.

Q: Does shaking a can of soda make it flat? A: Shaking a can of soda causes the carbon dioxide gas to come out of solution rapidly, but a significant portion of this gas is held in the can's headspace until you open it. While it helps release carbonation, it's a very messy method.

Q: Can I heat a canned drink in the microwave to make it flat? A: Yes, you can microwave a canned drink, but you must first pour it into a microwave-safe container. Do not microwave the aluminum can. Heat in short intervals and stir to release the gas.

Q: Does putting a paper towel in the drink actually work? A: Yes, the paper towel method works by creating numerous nucleation sites, which are points where bubbles can form and escape the liquid. It is a gentle but effective method that doesn't affect the flavor.

Q: Will leaving a can open eventually get rid of all the carbonation? A: Yes, simply leaving a can open to the air will cause the carbonation to dissipate naturally over several hours as the dissolved $CO_2$ reaches equilibrium with the atmospheric pressure.

Frequently Asked Questions

Carbonation is carbon dioxide ($CO_2$) gas dissolved in a liquid under pressure. To remove it, you need to disrupt the equilibrium by releasing the pressure and adding energy, either through agitation, heat, or by introducing nucleation sites for the gas to escape.

The best methods are physical ones that don't involve adding ingredients. An aggressive pour, vigorous stirring, or the paper towel trick will all reduce fizz without altering the drink's flavor.

Yes, using a blender is an extremely effective, albeit loud and potentially messy, method. Blending the drink for a few seconds will agitate the liquid intensely, forcing a rapid release of dissolved carbon dioxide.

Shaking a can introduces numerous tiny bubbles of $CO_2$ throughout the liquid. When opened, the sudden pressure drop causes these bubbles to expand and rush out simultaneously, creating a foamy overflow.

Adding a tiny amount of salt or sugar works for any carbonated drink by providing nucleation points. However, it will change the beverage's flavor profile and can cause an explosive reaction, so proceed with caution.

Yes, heating can alter a drink's flavor, particularly with heat-sensitive ingredients. The stovetop method should be done gently to minimize taste changes. It is best to chill the drink again after decarbonation.

No, freezing a carbonated drink is dangerous. As the liquid freezes and expands, it can cause the sealed can to explode due to the pressure buildup.
