Can You Put Sparkling Water in Stainless Steel?

Sparkling water has surged in popularity in recent years as more people choose it over sugary sodas and flavored drinks. With its crisp taste and hydrating benefits, it has become a staple for daily routines, outdoor activities, and even fitness hydration. But a common question arises: Can you safely put sparkling water in stainless steel bottles or tumblers?

The answer is a clear yes — and not only is it safe, but stainless steel is also one of the best materials to preserve the quality, freshness, and bubbles of sparkling water. Here’s everything you need to know.

Why Stainless Steel Is the Best Choice for Sparkling Water

Stainless steel offers durability, safety, and insulation benefits that plastic or aluminum simply can’t match.

• Non-reactive material: Sparkling water is mildly acidic due to carbonation, but food-grade stainless steel does not corrode or leach harmful chemicals, unlike some plastics.
• Superior insulation: Double-wall vacuum insulation keeps sparkling water cold for hours, which is key because chilled water retains carbonation longer.
• Pure taste: Unlike aluminum or low-grade plastic that can affect flavor, stainless steel maintains a clean, refreshing taste.

In fact, a report from the Harvard T.H. Chan School of Public Health confirms that sparkling water is just as hydrating as regular water and completely safe to enjoy daily — as long as it’s stored in safe, high-quality containers.

Does Sparkling Water Lose Carbonation in Stainless Steel?

The biggest myth is that carbonation leaks out faster in stainless steel. In reality, carbonation loss is determined by the seal quality of the lid, not the container itself. A poorly sealed cap will allow carbon dioxide to escape, leaving your drink flat.

That’s why the BriteLune 40 oz Tumbler is engineered with a 100% leakproof lid. Combined with its triple-layer insulation, it keeps sparkling water fizzy, icy-cold, and fresh for 30+ hours — even on hot summer days or during workouts.

Stainless Steel vs. Plastic and Aluminum

Plastic bottles may be cheap and lightweight, but they pose long-term problems. Sparkling water’s acidity can slowly break down plastic, leading to microplastic release. Plus, exposure to heat (like leaving a plastic bottle in your car) worsens this risk.

Aluminum cans, while recyclable, often have inner linings that can alter taste or degrade over time. By contrast, stainless steel is food-grade, toxin-free, and endlessly reusable — making it the clear winner.

The Environmental Protection Agency (EPA) emphasizes that replacing single-use plastic bottles with reusable stainless steel containers is one of the most impactful ways individuals can reduce plastic waste.

Best Practices for Enjoying Sparkling Water in Stainless Steel

To maximize freshness and fizz when using stainless steel tumblers:

• Keep it cold – Carbonation holds better at lower temperatures. Fill with ice before adding sparkling water for extra chill.
• Seal immediately – After each sip, close the lid tightly to prevent gas from escaping.
• Choose high-quality steel – Premium tumblers like BriteLune use 18/8 stainless steel that resists rust, dents, and flavor transfer.
• Clean regularly – Use warm soapy water or a straw brush to keep your tumbler fresh and odor-free.

The BriteLune Tumbler not only checks all these boxes but also offers a sleek, feminine design that fits perfectly into cup holders — making it an everyday essential for hydration with style.
