From lemon to peach-apricot, these drinks now fill supermarket aisles and Instagram feeds alike. Behind the fresh, wellness-style branding, French consumer group 60 Millions de consommateurs has been asking a blunt question: what exactly is in those bottles, and how are they treated before they reach your glass?
Flavoured water is not the same as mineral water
The first twist concerns the legal status of flavoured water. The name suggests “water, just nicer”, but regulators see something else entirely.
In France, even when a flavoured drink starts life as natural mineral water or spring water, it no longer keeps that protected status once aromas, sweeteners or other ingredients are added. It moves into a different legal category, closer to a soft drink than to plain bottled water.
Once flavours are added, the product loses the special “mineral” or “spring” protection and can be treated like any other processed beverage.
This switch of category matters for two reasons: the types of treatment allowed and the way consumers perceive risk. Many shoppers still believe they are buying “just water with a hint of fruit”, when in regulatory terms they are closer to a lemonade with toned‑down sugar.
What “treatment” can mean for bottled flavoured waters
Because flavoured waters are treated as soft drinks, producers may use similar disinfection methods to those used for tap water or other processed beverages. That can include filtration, UV treatment, ozonation or other techniques aimed at killing microbes and stabilising the product.
None of this is secret, but the nuance often disappears on front labels. You see fruit, sunshine and alpine peaks. You rarely see mention of industrial treatment steps, even if they are perfectly legal and controlled.
Flavoured water is closer to a manufactured drink than to a simple bottled spring, both in process and in regulation.
For people choosing bottled water to avoid any treated liquid, this distinction makes a real difference. If your priority is minimum processing, a basic bottle of still spring water or tap water filtered at home may actually fit your goal better than the trendy citrus version next to it.

The sugar question: pleasure drink, not neutral hydration
The second major gap between image and reality lies in nutrition. Grab a standard 20 cl glass of many flavoured waters, and you might be sipping roughly the same sugar as a small lemonade.
According to data highlighted by 60 Millions de consommateurs, a 200 ml serving typically contains between 5 and 10 g of sugar. Some brands climb to 15–16 g. Put that into something more concrete: one standard sugar cube is around 4 g.
- 5 g sugar ≈ 1¼ sugar cubes per 20 cl
- 10 g sugar ≈ 2½ sugar cubes per 20 cl
- 16 g sugar ≈ 4 sugar cubes per 20 cl
At those levels, these drinks clearly belong in the “treat” camp rather than the “drink all day” camp. They can be useful for weaning someone off full‑fat soda, but they are not a neutral alternative to water.
Many flavoured waters deliver sugar amounts that rival classic fizzy drinks, just with a healthier-looking label.
For children and teenagers, who already exceed recommended free sugar intake in many countries, a daily habit of sweetened flavoured water pushes the needle in the wrong direction. The risk is less about a single bottle, more about a pattern of constant, slightly sweet sipping.
Zero-sugar options: better, but not perfect
Supermarkets now carry plenty of “no sugar” or “zero” flavoured waters, often sweetened with intense sweeteners. They remove calories and direct sugar load, which can help for weight management or for people with diabetes.
Yet questions remain around long‑term sweetener intake and taste conditioning. A child who only knows drinks that taste strongly sweet, even with no calories, may find plain water dull and drink less of it.
Checking labels for both sugar and sweeteners gives a clearer picture:
- Look for “sugars: 0 g” per 100 ml if you want a true sugar‑free option.
- Scan the ingredients for terms like aspartame, acesulfame K, sucralose or stevia glycosides.
- Note the flavour intensity: milder-tasting waters often condition the palate less toward constant sweetness.
Behind every bottle, a local cash machine
The debate around bottled water often stops at health and plastic waste. Yet for many towns sitting on prized springs, bottled water – including flavoured variants – is big business.
In France, companies that extract and bottle water pay local authorities a royalty based on volume. That fee is set locally up to a legal cap of €0.58 per hectolitre (100 litres). Exports can be exempt.
On top of that, there is an extra nationwide contribution of €0.53 per hectolitre. This additional sum goes to fund pensions for self‑employed farmers. Together, those flows create a discreet but powerful income stream for certain rural areas.
| French water town | Revenue from bottling (2024) |
|---|---|
| Volvic | €3.8 million |
| Vittel | €2.3 million |
| Évian-les-Bains | €2 million |
| La Salvetat-sur-Agout | €1 million |
These figures show why debates around water extraction, environmental sustainability and local jobs can become heated. Bottling brings tax revenue, brand prestige and employment. It also raises questions about long‑term resource use in regions already under climate pressure.
For some towns, water in a bottle is not just a drink; it is a major slice of the local budget.
How to read a flavoured water label like a pro
For UK and US shoppers, rules differ from French ones, but the reflexes remain the same. A quick label scan can reveal whether you are holding a lightly flavoured drink or a disguised soda.
Four checks before putting it in the trolley
- Sugars per 100 ml: Anything above 4–5 g starts to look like a soft drink. Multiply by the bottle size to see the total.
- Ingredients list: If sugar, glucose-fructose syrup or fruit juice from concentrate appear near the top, sweetness is a core feature.
- Type of water: Terms like “spring water” or “mineral water” on the front may simply indicate the base, not the final legal status.
- Additives and sweeteners: Long lists do not automatically mean unsafe, but they confirm you are buying a processed beverage, not just water.
Rotating between plain tap water, sparkling water and the occasional flavoured option usually keeps taste buds happy without turning every drink into a dessert.
Common terms that confuse shoppers
Marketing around hydration leans on a cluster of fuzzy words. Understanding a few helps cut through the noise.
- “Aromatised” or “flavoured”: Often means the fruit component is mainly aroma, not juice. That can reduce calories, but does not automatically mean low sugar if sweeteners are added separately.
- “Light” or “reduced sugar”: Indicates less sugar than a reference drink, not necessarily a low level in absolute terms.
- “With fruit juice”: Sounds wholesome, yet juice still contributes free sugars. Your body treats them much like sugar from a can of cola.
Seeing these terms as clues rather than health claims helps reframe the choice. You are not choosing between “healthy” and “unhealthy”, but between a range of treats and more neutral options.
What a day of flavoured water can look like
Consider a simple scenario for an adult trying to “drink better”:
- Morning: 500 ml lemon flavoured water at 5 g sugar per 100 ml = 25 g sugar.
- Afternoon: 330 ml peach flavoured sparkling water at 4 g sugar per 100 ml ≈ 13 g sugar.
- Evening: 250 ml “light” berry water at 3 g sugar per 100 ml ≈ 7.5 g sugar.
By bedtime, that adds up to 45.5 g of sugar, before any food, tea, coffee or dessert. Yet the person may feel they avoided “proper” soft drinks all day.
Swapping just one of those bottles for plain or unsweetened sparkling water halves the sugar hit with almost no change in routine. That kind of small adjustment often beats drastic resolutions that do not last.
When flavoured water makes sense
Despite the concerns, flavoured waters are not villains. They can help someone who hates plain water stay hydrated during a brief heatwave or post‑exercise. They can replace higher‑sugar sodas at social events without feeling punitive.
The key is treating them as you would a light dessert yogurt or a flavoured coffee: enjoyable, useful in context, but not your baseline source of hydration. Keeping that mental category shift in mind may be the most practical lesson from the work of 60 Millions de consommateurs and other consumer experts tracking what really flows from those glossy bottles.
