Less sugar, zero, natural: what are consumers comparing your syrup with?
Less sugar, zero, natural: drink syrups and squashes now make the same promises as soft drinks. But a concentrate is no longer only compared with another concentrate. It can stand in for a fizzy drink, flavour a gym bottle or recreate a café drink. We analysed more than 40,000 consumer reviews across Europe to understand when the same sugar-reduction promise convinces, and when it disappoints.
- One concentrate, four missions. Getting back a familiar taste, making water enjoyable, replacing a ready-to-drink beverage, recreating a café or restaurant drink.
- Each mission brings its own reference competitor: the original recipe, plain water, the bottled iced tea, the café drink. That reference sets what the product has to prove on taste, sugar and sweeteners.
- Zero is judged differently, not more kindly. "Close enough" is accepted for flavoured water; against a familiar taste, a sweetener aftertaste becomes a reason to switch. In Germany, the artificial aftertaste remains the first barrier even when hydration drives purchase.
- "Natural" is three expectations, not one: credible fruit, no sweeteners, a simple composition.
- For brands, the question shifts from "should we cut sugar?" to "are we lightening an existing habit, or answering a different occasion against a different competitor?"
Two UK squash reviews on Ocado, both about recipes built on less sugar, with opposite verdicts:
“I must start by saying I have NEVER found a squash with sweetener that I like. This has now changed and I am addicted. Yes I use far more than you are supposed to because I like to taste it, but hey its low enough calories to do that so all good”
Review of Vimto Remix Raspberry, Orange & Passionfruit Squash, 5/5, United Kingdom.
“This has been our go to squash for years! Loved that it actually tasted like blackcurrants and not of artificial flavours, but sadly that's no longer the case. This new formula is nothing like the original :(”
Review of Rocks Blackcurrant Squash, 1/5, United Kingdom.
What separates them is not the label. It is what each person wanted in the glass, and what they were comparing it with. That question mattered little while a squash was mainly compared with another squash. It becomes strategic when the boundaries between drinks start to move.
Why this matters now
Concentrates present themselves as an alternative to ready-to-drink. Innova describes drink concentrates and mixes as "a convenient, customizable, and cost-effective alternative to ready-to-drink beverages", with launches growing and sugar-free tripling its share since 2021 (Innova Market Insights, August 2026).
The same bottle can imitate a branded soda. In France, the syrup range of SodaStream, owned by PepsiCo since 2018, sits Pepsi, 7Up and Lipton Ice Tea concentrates, an Energy line and alcohol-free cocktail bases next to grenadine and mint; eleven of its syrups are sugar-free (SodaStream France; PepsiCo, December 2018). The reference is no longer just a fruit cordial: it can be a drink the consumer knows by heart.
In Germany, boundaries are crossed both ways. Sports-nutrition brands sell ultra-concentrated zero syrups (65 ml diluted at 1:154 for More Nutrition, product page), and the dm and Rossmann drugstores have their own zero lines. In the other direction, the traditional syrup brand TRi TOP is launching a ZERO range at a 1+7 dilution in April 2026, citing NielsenIQ data showing that zero already accounted for 25.2% of litres sold in the category in 2025 (DrinkStar, March 2026, company-reported figure).
Functional claims are reaching concentrates and their neighbours. Robinsons launched a no-added-sugar squash range with added vitamins in 2023 (Britvic, May 2023). In the US, Coca-Cola is piloting prebiotic-fibre versions of three sodas from late October 2026 in parts of New York, New Jersey and Pennsylvania (Food Dive, 7 October 2026). A regional US pilot is not a European trend, but it suggests that an added benefit may do less and less to set one category apart from another.
Zero is not the only answer to sugar. A quarter of adults in Germany say they permanently avoid added industrial sugar, yet a third of them consume no "Zero Sugar" products (YouGov, October 2026).
Each of these moves puts the concentrate against a different competitor. What does that change in how consumers judge the product? That is where reviews help.
1. The first glass: finding the fruit, holding the sugar
In the UK, France and Poland, the first use of household syrups and squashes is the simplest: concentrate in water, poured by hand. About two in five UK reviews of squashes and cordials mention diluting with still water. People rarely follow the ratio to the letter; they set it to reach a particular taste. And that setting reveals how they judge the product.
Strength, sweetness and yield move together in reviews. "A little goes a long way" signals both a fruitier product and better value.
There is a limit. An analysis of syrups sold in Germany puts it plainly: self-dosing cannot fully correct a poorly balanced base. Dilution adjusts a preference; it does not repair a fault.
2. One concentrate, four missions
Reviews show at least four missions. They do not map onto countries: they coexist within markets and vary with the occasion and the type of product. What changes from one to the next is the competitor the product is measured against.
Getting back a familiar taste
Any change is noticed, and UK loyalists leave in a sentence after a reformulation (Rocks, above). The same mechanism appears elsewhere: a French reviewer misses the mint "of the cafés and diabolos of our childhood"; in Poland, "homemade" is the leading theme in reviews of household syrups; in Switzerland, it is the family classic everyone agrees on, and loyalty rests on the taste staying the same.
Making water enjoyable
This is the dominant mission for zero syrups sold in Germany, and everyday hydration is the first use of squash in the UK. The product does not have to replicate an original. It must stay light, carry enough flavour and not seem artificial.
Replacing a ready-to-drink beverage
Here the product name sets up an expectation of resemblance, and reviewers judge the concentrate against the bottle it replaces:
„Man erwartet von Zirups oft ein Ersatz Getränk […] aber es schmeckt halt wirklich nach orangen ice tea.“
(“You often expect a syrup to be a replacement drink […] but it really does taste like orange iced tea.”)
Review of Sportness Zero Sirup Orange-Icetea (dm), 3/5, Germany. Translated from German.
„Nicht do süß wie diese Eistees in den Flaschen von den großen Marken. Angenehmer Geschmack in Richtung „echtem Tee“.“
(“Not as sweet as those bottled iced teas from the big brands. A pleasant taste, more towards ‘real tea’.”)
Review of WellMix Zero Sirup Ice Tea Peach (Rossmann), 5/5, Germany. Translated from German.
„Leider kein authentisches Geschmacksprofil. Die Süßungsmittel dominieren im Vergleich z. B. zu Ice Tea Peach den Geschmack und dadurch schmeckt es eher billig.“
(“Sadly not an authentic taste profile. Compared with Ice Tea Peach, for example, the sweeteners dominate the taste, and that makes it taste rather cheap.”)
Review of Sportness Zero Sirup Rhabarber (dm), 2/5, Germany. Translated from German.
In the UK, the drink being replaced is often alcoholic: close to one review in five of squashes and cordials mentions an alcohol-free alternative to wine or gin.
Recreating a drink from outside the home
The contract here is an exact replica. In Poland, reviews of a professional red-berry syrup keep returning to the same benchmark:
„super syrop, herbata smakuje jak ta zimowa z popularnej restauracji pod znakiem M“
(“Great syrup, the tea tastes like the winter one from the popular restaurant with the M sign.”)
Review of Monin Fruits Rouges syrup, 5/5, Poland. Translated from Polish.
In the same country, household syrups are judged on homemade authenticity: two different expectations within one market.
What about functional benefits? Functional syrups are still rare in the reviews analysed. The question they raise is already visible in the other missions: any added benefit will have to live with the sensory demands of the mission it serves. This is a hypothesis to examine, not a finding.

3. What each mission changes for zero
Across European household syrups, the Sensia analyses read clearly:
- When the goal is a familiar taste, reduced sugar is attractive only if it preserves the taste of the full-sugar version, and a sweetener aftertaste becomes a reason to switch.
- When the goal is flavoured water or a soft-drink substitute, tolerance is higher: "close enough" is accepted for an almost calorie-free product, but not when the product presents itself as an authentic substitute.
That tolerance has limits, and this is where checking matters. In Germany, a single brand accounts for most reviews of zero syrups. To separate that brand's effect from a category expectation, we re-ran the same analysis on every other syrup sold in the country: retailer own labels, competing fitness brands, traditional and professional syrups.
- What holds: taste first, sugar-free second. Flavouring water stays the first use, and "helps me drink more water" is cited as a reason to buy in about one review in five.
- What emerges: the artificial aftertaste remains the first barrier, now followed by a taste that does not match the label. The second main theme in how people talk about these products is an authenticity test against the real fruit.
- What it means: the hydration benefit does not cancel the sensory demand. It changes its criteria.
„Ich finde der sirup schmeckt ganz gut,finde nur im abgang merkt man das künstliche nur nen ticken zu doll.aber allem in alem schmeckts […]“
(“I think the syrup tastes pretty good, you just notice the artificial a bit too much in the finish. But all in all it tastes good […]”)
Review of Sportness Zero Sirup Pfirsich Eistee (dm), 4/5, Germany. Translated from German.
„schmeckt viel zu süß und einfach nicht lecker… ich hätte mir was viel besseres vorgestellt, das eher fruchtig als nur nach süssungsmitteln schmeckt“
(“Far too sweet and simply not nice… I expected something much better, that tastes of fruit rather than just sweeteners.”)
Review of Sportness Zero Sirup Orange-Icetea (dm), 2/5, Germany. Translated from German.
So zero does not simply win against water and lose against the original. It can fail in every mission, but not for the same reasons. And when it succeeds, it can free people from the dosing trade-off, as the Vimto reviewer shows.

4. Three kinds of "natural"
"Natural" covers at least three expectations that reviewers keep apart. Across the household syrups analysed in Europe, the first two emerge as separate reasons to buy, cited at similar frequencies. A syrup can taste convincingly of fruit and contain sweeteners; another can contain no sweetener and still taste too sugary.
Some consumers take a third route, which echoes YouGov's finding on people who cut sugar without adopting zero:
« Avec moins de 2% de sucre avant dilution, le meilleur produit pour aromatiser une eau tout en limitant l'apport en sucre et sans édulcorant. »
(“With less than 2% sugar before dilution, the best product to flavour water while limiting sugar intake, and with no sweetener.”)

What this means for brands
The points below are Sensia's interpretation of the findings above.
The underlying question is a portfolio choice: are you lightening an existing habit, or answering a different occasion against a different competitor? The two ambitions can lead to different decisions on formula, format, dosage, message and which brand carries the offer. Reviews do not dictate the decision; they clarify what to check before making it.
| Decision | What reviews show | Hypothesis to examine |
|---|---|---|
| Reformulate a core product or launch a variant | When buyers want a familiar taste, any change is noticed and can be enough to lose them. The Swiss household-syrup analysis notes that innovation is better accepted as a variant than as a replacement of the core recipe | How many buyers are anchored in taste continuity? Could a parallel variant recruit without exposing the core? |
| Target a new mission (water, soft drink, café) | Each mission brings its own reference competitor, and the product name sets up an expectation of resemblance | Which drink does the consumer have in mind, and is the formula close enough? Which brand is most credible to carry it? |
| Lead the message with zero | In a hydration routine, sugar-free is a reason to buy in its own right. Against a familiar taste, it mainly raises fear of a compromise | In which missions does zero drive purchase, and where must a taste proof come first? |
| Claim naturalness | Fruit credibility, no sweeteners and composition are three distinct expectations | Which kind of natural can the brand prove, and which does its buyer expect? |
| Defend a premium price | Value is built in use: a small dose with plenty of fruit justifies the price; a weak flavour that forces a double dose destroys it | Does the stated yield hold at the strength consumers actually prefer? |
| Add a functional benefit | Little documented in reviews so far | Does the benefit hold without degrading the sensory demands of the target mission? |
Ideas often raised, such as dosing closures or serve-specific ratios (still, sparkling, hot, tea), respond to real frictions. They are hypotheses to test; the reviews do not validate them yet.
FAQ
Is "zero sugar" a reason to buy drink syrups?
It depends on the mission. When the syrup is used to make water enjoyable, sugar-free is a reason to buy in its own right. When the consumer wants a familiar taste back, it is judged against the full-sugar version and a sweetener aftertaste becomes a reason to switch.
What do consumers mean by a "natural" syrup?
At least three different things: a credible fruit taste, the absence of sweeteners, and a simple composition. They are distinct expectations, and a product can meet one without meeting the others.
Do these findings apply to brands outside the corpus?
They describe how the category is judged, not how any brand performs. They can inform a brief, a range architecture or a claims discussion, whatever the brand.
What we listened to
Scope: online consumer reviews from the Sensia Space "Beverages — Drink Syrups & Concentrates — Europe", published on retailer and marketplace sites. Products are grouped by use: household syrups and squashes diluted at home; zero-sugar and fitness syrups; professional bar and barista syrups.
Measures: ranks and shares are established within the reviews analysed; one review can cover several themes. Between countries, we compare ranks, not levels.
Composition: differences between countries partly reflect the products and channels observed. UK reviews come largely from one online grocer; in Switzerland, the household syrups observed are mostly Migros products; in Germany, one brand dominates the zero segment, and every finding presented for Germany was checked without it. Soft-drink concentrates and functional syrups are scarce in the corpus.
Positivity bias: reviews lean positive, so complaints signal friction rather than its incidence in the population.
Quotes: excerpts from real reviews, reproduced as published, shortened where marked […], and translated when not in English. Reviews from product-testing programmes are excluded from quotes.
External sources: market context checked on 30 October 2026 and linked in the text. Innova's figures cover product launches, not sales; the TRi TOP figure is reported by the company; the Coca-Cola pilot concerns the US.
