Why Carbonation and Owala Bottles Don't Mix
The primary reason you should not put carbonated drinks in an Owala bottle, especially models with a sealed lid like the FreeSip, is the high-pressure environment created by the carbon dioxide ($ ext{CO}_2$) gas. Carbonated beverages, like soda and sparkling water, are created by dissolving $ ext{CO}_2$ into a liquid under pressure. An Owala bottle's leakproof sealing mechanism is designed to trap liquid, but it also effectively traps the gas, allowing pressure to build up inside the container as the drink warms or is shaken.
The Danger of Pressure Buildup
When you press the button on a FreeSip lid, the spout pops open with a forceful spring-loaded action. This works perfectly for water, but when filled with a carbonated beverage, the release of the lid also releases the trapped, pressurized gas. This can result in a sudden, forceful spray of liquid, which could cause a messy spill or, in a worst-case scenario, injure someone, particularly if they are holding the bottle too close to their face. The manufacturer specifically warns about this risk, advising users to always open the bottle with caution.
Risks to Your Bottle's Integrity
Beyond the risk of injury, the constant stress from internal pressure can wear down the bottle's components over time. The seals and gaskets that ensure a leakproof experience are not designed for sustained pressurization. This could lead to a compromised seal, resulting in leaks even with non-carbonated liquids in the future. The acidic nature of many sodas can also potentially degrade stainless steel finishes, affecting the bottle's longevity and appearance, though this is less of a concern with high-quality food-grade stainless steel.
Owala's Official Stance and Product Variations
Owala's own FAQ section is very clear on this topic, stating that models like the Stainless Steel FreeSip are "Not for use with hot, carbonated, or perishable liquids". However, the company makes distinctions between different product lines. For example, their 40oz Tumbler and 24oz Tumbler are explicitly listed as able to hold "cold, carbonated, and hot drinks". This is because tumblers generally have a less-restrictive, non-sealed lid design that allows for pressure to dissipate safely, often through a straw hole or an open mouthpiece.
Owala Product Comparison: Carbonated Drinks
| Feature | Owala FreeSip (Sealed Lid) | Owala Tumblers (Open Mouthpiece) |
|---|---|---|
| Suitability for Carbonation | Not Recommended | Suitable, but with caution |
| Pressure Buildup Risk | High Risk (Sealed container) | Minimal Risk (Vented lid) |
| Leakage Potential | High (Sudden spray upon opening) | Low (Less forceful pressure release) |
| Lid Mechanism | Spring-loaded, sealed | Open mouthpiece with straw |
| Manufacturer Recommendation | Avoid carbonated liquids | OK for carbonated liquids |
| Primary Function | Leakproof for still liquids | Insulated for various beverages |
Recommendations for Enjoying Fizzy Drinks
If you absolutely want to enjoy a carbonated beverage in an insulated container, here are some safer alternatives and methods:
- Use a Tumbler: Opt for an Owala Tumbler or a similar product with a vented lid. These designs prevent the dangerous pressure buildup associated with sealed containers.
- Choose Purpose-Built Bottles: Certain brands, like SIGG, manufacture bottles specifically certified to be leak-proof with carbonated drinks. Sodastream also makes insulated bottles for their sparkling water.
- Venting Technique: For bottles with a screw-on lid, experienced users sometimes recommend opening the bottle slowly and cautiously to release pressure before fully unscrewing the cap. This is still risky and not endorsed by Owala for their FreeSip models.
- Flat is Safer: If your goal is just to keep a cold drink, let the carbonation dissipate or go flat before pouring it into a sealed bottle. While the taste may be different, it eliminates the pressure risk.
Final Thoughts on Owala and Carbonation
When it comes to answering the question, "Is it okay to put carbonated drinks in Owala?," the answer is a clear no for the FreeSip and other sealed-lid bottle models. The risks of pressure buildup, potential liquid spray, and damage to the bottle's seals far outweigh the convenience of an insulated beverage. While Owala tumblers are designed for carbonated drinks, exercising caution is still wise. For safe, worry-free hydration, stick to what the manufacturer recommends: reserve your sealed Owala bottle for still liquids and use a proper container for anything with fizz.

How to Safely Enjoy Fizzy Drinks with Owala
For those with Owala tumblers designed for carbonation, follow these best practices for safety and the best experience:
- Leave Space: Don't fill the tumbler to the very top. Leaving some headspace allows for gas expansion without excessive pressure building directly under the lid.
- Avoid Shaking: Vigorously shaking any carbonated drink, regardless of the container, will increase pressure. Be gentle when carrying it.
- Clean Thoroughly: The acidic nature of soda and the sugar in many carbonated drinks can cause residues. Clean your tumbler thoroughly after each use to prevent odors and corrosion.
- Listen and Look: Before taking a sip, listen for any hissing sounds and look for any unusual bubbling, which could indicate a pressure issue. The open design minimizes risk, but awareness is still important.
- Use with Ice: Adding ice to the drink can slightly reduce the temperature and, therefore, the pressure. However, this is not a substitute for proper container usage.
Following these steps ensures you can enjoy your favorite fizzy beverages while keeping both yourself and your Owala product safe. The distinction between the FreeSip's sealed design and the tumbler's vented one is the critical factor in making the right choice for your drink.
