# Cutting Sugar in RTD Drinks with Maltitol, Erythritol and Stevia

Sugar taxes, front-of-pack labelling and consumer demand have pushed sugar reduction from a novelty to a baseline requirement. The challenge is that sugar does more than sweeten: it carries body, masks bitterness and shapes the finish. Replace it carelessly and the drink tastes thin or metallic.

Build a blend, not a swap
-------------------------

Most successful light drinks use two or three sweeteners together. High-intensity sweeteners like stevia or sucralose supply the sweetness, while a bulk sweetener such as erythritol or maltitol restores body. A small amount of the original sugar often stays to round off the profile.

- **Erythritol:** clean taste, near-zero calories, low laxative effect. Can add a slight cooling note.
- **Maltitol:** sugar-like sweetness and body, good for syrups, but higher GI impact and laxative threshold.
- **Stevia (Reb M):** high sweetness, clean label, but needs masking at high doses.

Watch the mouthfeel
-------------------

Reducing solids lowers viscosity and changes how flavour releases. Gums, soluble fibre or a touch of polydextrose can restore the weight that sugar used to provide. Carbonation can amplify or hide these effects, so always taste the finished, chilled product.

**Buyer tip:** validate every blend in a real accelerated shelf-life test. Sweetener systems can drift in perception as other ingredients age.

Labelling implications
----------------------

Polyols must be declared with their energy value, and some markets require a laxative warning above set thresholds. Stevia and erythritol carry different regulatory stories market by market. Check the destination rules before locking a recipe, because a label change can force a reformulation.
