A Buyer’s Guide to Sparkling Water in the UK

As more of us move away from sugary soft drinks, the world of sparkling water has expanded dramatically. What was once a simple choice between still or sparkling has become a complex aisle filled with flavoured sparkling water, sparkling mineral water and a host of other healthy fizzy drinks. While the variety is welcome, it also brings a few common pitfalls that can lead to a disappointing purchase.

As the Joybuy Product Recommendation Officer, my role is to help you navigate this market. Let's cut through the marketing clutter and focus on what truly matters, ensuring your next sip is as refreshing and satisfying as you expect.

The Common Traps When Buying Sparkling Water

1. The "Natural Flavour" Mirage: The term "natural flavouring" on a label can be ambiguous. While it suggests a taste derived from real fruit, the reality can sometimes be a flavour profile that tastes more artificial than authentic. This often leads to drinks that are either disappointingly bland or have a synthetic, overpowering taste that misses the mark.
2. The Hidden Sweetener Aftertaste: In the quest for zero sugar sparkling water, many brands turn to sweeteners. However, not all are created equal. Some can leave a distinct and often unpleasant aftertaste that lingers long after the drink is finished. It's a common complaint from those seeking a clean, crisp refreshment but ending up with a flavour that feels compromised.
3. Paying a Premium for Ambiguous Origins: Do you know the difference between sparkling mineral water and sparkling spring water? Many consumers don't, yet the distinction can impact both taste and price. Paying a premium price is only worthwhile if the product's source and quality justify it.

Decoding the Label: Key Factors to Check Before You Buy

To avoid these traps, focus on a few core parameters. A quick check of the label can tell you everything you need to know.

1. Water Source and Type

The foundation of any good sparkling water is the water itself. Understanding the terminology is key to finding a product that matches your preference for taste and purity.

• Sparkling Mineral Water: This water originates from a geologically and physically protected underground source. It is bottled at the source and has a consistent mineral composition. Brands like Icelandic Glacial or San Pellegrino fall into this category, often prized for their unique mineral profile and clean taste.
• Sparkling Spring Water: This also comes from a specific underground source and is bottled there, but its mineral content can fluctuate. Brands like Highland Spring are a great example, offering pure water sourced from protected land.
• Carbonated Water: This is the most general term. It can be any water that has been infused with carbon dioxide gas. While perfectly fine, it doesn't carry the same guarantee of a specific, protected source as mineral or spring water.

2. Sweeteners and Flavourings

For those who enjoy flavoured sparkling water, the ingredients list is your most important tool.

• Sweeteners: Look for what is used to achieve the "zero sugar" claim. Some products use sweeteners like erythritol or steviol glycosides (stevia), which are derived from natural sources and are often preferred for having less of an aftertaste. Others may use sucralose or acesulfame potassium.
• Flavour Source: Check if the flavour comes from "fruit juice concentrate" or "natural [fruit] flavour." The inclusion of real juice, even in small amounts, can provide a more authentic taste compared to generic "natural flavourings."

3. Packaging and Format

How your water is packaged affects sustainability, convenience and even taste.

• Sparkling Water Cans: Aluminium cans are infinitely recyclable and often have a higher recycled content than plastic. They also protect the water from light, which can affect taste, and tend to chill faster and stay cooler for longer.
• Multipacks: If you're a regular consumer, buying a sparkling water multipack online is often more economical and convenient. It ensures you always have a healthy, refreshing option on hand, whether for daily hydration, entertaining guests or as a sophisticated mixer.

Frequently Asked Questions About Sparkling Water

Is sparkling water as hydrating as still water?

Yes. From a hydration perspective, plain sparkling water is considered to be just as effective as still water. The carbonation does not reduce its ability to hydrate your body.

Does sparkling water damage your teeth?

Plain, unflavoured sparkling water is only minimally more acidic than still water due to the carbonic acid formed during carbonation. The risk to tooth enamel is very low. The concern increases with flavoured varieties that contain added citric acid and sugars, but they remain a significantly better choice for dental health than traditional sugary fizzy drinks.

What is the difference between sparkling mineral water and club soda?

The main difference lies in the source and additives. Sparkling mineral water is sourced from a natural spring or well and contains naturally occurring minerals; its carbonation can be natural or added. Club soda, on the other hand, is water that has been artificially carbonated and has had mineral-like compounds (such as potassium bicarbonate or sodium citrate) added for taste.
