More Zerup Too Sweet or Tastes Artificial? 9 Fixes for Zero Syrup

If you've tried More Zerup or another zero-sugar syrup and found it cloying, artificial or just "off," you are not alone. In the reviews we read in October 2026, sweetness and aftertaste were among the most frequent criticisms. This guide explains why zero syrup can taste too sweet or soapy, and gives you nine simple ways to fix it.

Why does zero syrup taste too sweet or artificial?

Zero-sugar syrups replace sugar with intense sweeteners—typically sucralose (E955) and acesulfame K (E950) in More Zerup and in ZERUP by LUVA. These sweeteners are hundreds of times sweeter than sugar, so only tiny amounts are needed. That creates a challenge: the sweetness arrives immediately and lingers, but the fruit flavour (which comes mostly from flavourings rather than fruit juice) can feel thin or fleeting by comparison. The result is a drink that tastes very sweet but not very fruity.

Research on taste perception suggests that sensitivity to sweetness and to the bitter or metallic aftertaste of some intense sweeteners differs between people, partly because of genetics in bitter taste receptors. What one person finds refreshing, another may find soapy or chemical. Temperature matters too: colder drinks taste less sweet than warm ones, so a syrup drink at room temperature will taste much sweeter (and the aftertaste more obvious) than the same drink ice-cold.

On Amazon.de, one reviewer wrote of More Zerup Elderflower: "felt like licking a scented candle or soap, even at the lowest dose" (review). Another said of Pink Grapefruit: "too artificial and slightly soapy … I tried different mixing ratios but the odd aftertaste stayed" (review). A third complained: "Extremely sweet but no fruit flavour at all" (review). On Trustpilot, Katrin (September 2026) wrote: "too sweet for me and too little fruit flavour" (review).

The classic dilemma, as one Amazon.de reviewer put it: "Flavour could be a bit stronger. If you use more to get flavour, it becomes too sweet" (review). The fixes below address exactly that.

9 fixes for zero syrup that tastes too sweet or artificial

1. Start at half dose and build up

Most zero syrups recommend a dose per glass or litre. For ZERUP by LUVA, the standard mix is about 4 ml (a short squeeze, a little less than a teaspoon) in 500 ml of water. If that tastes too sweet, start with 2–3 ml and taste. You can always add more, but you cannot take it out. The table below shows light, normal and strong doses for ZERUP:

For More Zerup, according to More Nutrition's German website (checked October 2026), the recommended mix is about 1 part syrup to 154 parts water—roughly 3.2 ml per 500 ml. If reviews say it is too sweet at that ratio, try 2 ml and adjust.

2. Serve ice-cold

This is the single biggest fix. Sweetness is less intense when a drink is very cold. Make your syrup drink, add plenty of ice cubes (or chill it in the fridge for an hour), and taste again. For many people the aftertaste becomes less noticeable. ZERUP by LUVA is designed for ice-cold drinks in the UAE heat—serve it straight from the fridge or over ice for the best balance.

3. Use sparkling water instead of still

Carbonation adds a sharp, tingling bite that cuts through sweetness and makes the drink feel more refreshing. Many people who find zero syrup cloying in still water love it in sparkling. If you have a home sparkling-water maker, carbonate the water first, then add the syrup and stir gently (adding syrup before carbonating can cause a fizzy overflow). Try ZERUP Cola Orange or Blue Raspberry in sparkling water for a homemade sugar-free soda.

4. Add fresh lemon or lime juice

A squeeze of fresh lemon or lime juice (about half a teaspoon per glass) adds natural acidity that balances sweetness and brings out the fruit flavour. This works especially well with berry, tropical and iced-tea syrups. The acidity can also make a lingering sweetener aftertaste less noticeable. For ZERUP Peach Iced Tea or Lemon Iced Tea, a wedge of lemon turns it into a proper summer cooler.

5. Add fresh mint, cucumber or frozen berries

A few fresh mint leaves, a slice of cucumber or a handful of frozen raspberries or blueberries add real fruit and herb aroma without sugar. The natural oils and acids lift the flavour and make the drink taste less one-dimensional. Muddle the mint or cucumber lightly in the glass before adding water and syrup, or drop in the frozen berries and let them thaw as you drink. This trick works beautifully with ZERUP Dragonfruit Passionfruit or Blackberry.

6. Mix two flavours

Combining a sharp, sour flavour with a sweeter one can create a more balanced drink. Try half the usual dose of each—for example, 2 ml of a citrus syrup plus 2 ml of a berry syrup in 500 ml of water. ZERUP's Green Apple (the sharpest flavour in the range: crisp, sour) pairs well with sweeter profiles like Mango. Experiment until you find a blend you like.

7. Use a jug and stir properly

Syrup is denser than water and sinks to the bottom. If you squeeze syrup into a glass and do not stir, the first few sips taste of nothing and the last few are syrupy and sweet. Mix in a jug with a spoon (or shake in a bottle) to distribute the syrup evenly. For a 2-litre jug, use about 16 ml of ZERUP and stir well before pouring.

8. Use cold-brewed unsweetened tea as a base

For iced-tea syrups, try making the base yourself: cold-brew black or green tea overnight in the fridge (no sugar), then add a small amount of syrup for flavour. This gives you real tea tannins and a less sweet, more authentic iced-tea taste. Use about 2–3 ml of ZERUP Lemon Iced Tea (bright, sour lemon over black tea) per 500 ml of cold tea, taste and adjust. You can find more ideas in our guide to sugar-free iced tea.

9. Choose sharper flavour profiles

If you are sensitive to sweetness, avoid flavours described as "candy-like" or very fruity, and choose citrus, green apple or berry instead. In the ZERUP range, Green Apple is the sharpest (crisp, sour), Lemon Iced Tea is bright and tangy, and Blackberry has a tart edge. These profiles are less likely to taste cloying. We designed ZERUP's flavours to be fruit-forward and refreshing in ice-cold drinks; taste is personal, so try a few and see what you prefer.

Why ZERUP by LUVA may taste different

ZERUP by LUVA uses the same sweeteners as More Zerup (acesulfame K and sucralose, no aspartame), so if you dislike those sweeteners in general, the aftertaste may still be there. However, ZERUP's recommended mix is about 4 ml per 500 ml—a little stronger than More's recommended about 3.2 ml—so you can expect a fuller fruit flavour at the standard dose, which can help balance the sweetness. You also control the strength: start light (2–3 ml) if you are sensitive, or go stronger (5–6 ml) if you want bold flavour and do not mind sweetness.

ZERUP is a UAE brand from Dubai, delivered to all seven Emirates within 12 hours. One 65 ml bottle is AED 19, or any three flavours for AED 49 (mix and match, save AED 8). It is halal certified, caffeine-free and makes about 8+ litres at the recommended mix—about 16 glasses of 500 ml. The full ingredient list and nutrition facts are on every bottle and product page. ZERUP by LUVA launches on 5 November 2026.

The bottom line

If your zero syrup tastes too sweet, soapy or artificial, the fix is usually temperature, dilution and a little fresh citrus or fizz. Start with half the recommended dose, serve ice-cold over ice or in sparkling water, add a squeeze of lemon and choose sharper flavours—most people find that combination far more refreshing and balanced. Taste is personal, and intense sweeteners will never taste exactly like sugar, but with the right tweaks you can enjoy a sugar-free drink that actually quenches your thirst.

Frequently asked questions

Why does zero syrup taste too sweet even at the recommended dose?

Intense sweeteners like sucralose and acesulfame K are hundreds of times sweeter than sugar, and the sweetness lingers longer than the fruit flavour. Warm or still water emphasises sweetness; ice-cold sparkling water with a squeeze of lemon balances it. Start at half dose and build up until it tastes right to you.

Why does my zero syrup taste like soap or cleaning product?

Research on taste suggests that some people are genetically more sensitive to the bitter or metallic aftertaste of certain sweeteners, and some flavourings (especially floral or citrus ones) can taste soapy to them. Serving ice-cold, adding fresh lemon juice and choosing berry or apple flavours instead of elderflower or grapefruit often helps. If the soapy taste persists, that flavour may simply not suit your palate.

Can I use less syrup than the bottle says?

Yes, absolutely. The recommended dose is a starting point. If it tastes too sweet, use half and adjust. ZERUP's light dose is 2–3 ml per 500 ml; you will get more litres per bottle, and a subtler, less sweet drink.

Does sparkling water make zero syrup taste less sweet?

Yes. Carbonation adds a sharp, tingling bite that cuts through sweetness and makes the drink more refreshing. Many people who find zero syrup cloying in still water love it in sparkling. Carbonate the water first, then add syrup and stir gently.

Is the sweetener aftertaste in zero syrup harmful?

No. Sucralose and acesulfame K are approved sweeteners in the EU and the UAE, and extensive safety reviews have found them safe at normal intake levels. The aftertaste is a taste perception issue, not a health concern. Read our are sweeteners safe guide for the evidence.

Which ZERUP flavour is the least sweet or sharpest?

ZERUP Green Apple is the sharpest flavour in the range—crisp, sour, green-apple tang. Lemon Iced Tea is bright and tangy, and Blackberry has a tart edge. All ZERUP flavours use the same sweeteners, so "least sweet" depends on how much you use; sharper fruit profiles just balance the sweetness better.

Can I mix ZERUP with fresh fruit juice to make it less sweet?

Yes, though that adds sugar and calories from the juice. A better trick is to add a squeeze of fresh lemon or lime (almost no sugar) or a few frozen berries for aroma.

Does zero syrup taste better in cold or hot drinks?

Cold. ZERUP and other zero syrups are designed for cold drinks—ice-cold water, sparkling water, iced tea, ice cubes. Warm drinks taste much sweeter (temperature affects taste perception), and heating can change the flavour. Never heat ZERUP; it is not for coffee or cooking.
