Why Do Some E-Liquids Taste Sweet?

The sweetness in some e-liquids is a result of various factors, and it’s important to note that this sweetness doesn’t necessarily come from sugar. Here’s a breakdown of why some e-liquids taste sweet:

1. Absence of Sugar:

  • E-liquids do not contain sugar. The presence of sugar in e-liquids would be counterproductive as it could lead to rapid coil degradation at the high temperatures generated by vaping devices.
  • Sugar decomposes at temperatures above 149°C, which is easily surpassed by vape devices. Therefore, the sweetness in e-liquids is not derived from sugar.

2. Ingredients in Vape Juice:

  • Vegetable Glycerine (VG): VG is a natural extract derived from plant oils and is used as a solvent base in vape juice. It has a natural sweet taste, and high-VG e-liquids (70/30 mix ratio and above) may have a perceivable sweet taste.
  • Propylene Glycol (PG): PG, another major component of e-liquids, is known for its excellent flavour-carrying properties. While not sweet on its own, it contributes to the overall flavour profile of e-liquids.

3. Flavourings:

  • The flavourings used in e-liquids play a significant role in the overall taste, and some flavourings can impart a sweet taste. Manufacturers may not disclose the specific ingredients in their flavours for proprietary reasons.
  • Flavours can vary widely, from fruity to dessert-inspired, and the choice of flavourings contributes to the diversity of taste experiences in vaping.

4. Optional Ingredients:

  • Nicotine: Nicotine, when present, can have a slightly peppery taste, but it is not the primary contributor to sweetness.
  • Sweeteners: Some e-liquid manufacturers include artificial sweeteners to enhance sweetness. Common sweeteners include sucralose, erythritol, ethyl maltol, and stevia.
  • Sucralose: Known for its intense sweetness, but it can lead to gunk build-up on coils.
    • Erythritol: A sugar alcohol less sweet than sucralose, and it is gentler on vape coils.
    • Ethyl Maltol: Used to enhance flavours, especially those with a cotton candy taste.
    • Stevia: One of the sweetest sweeteners, but it can build up on coils.

5. Quality Matters:

The reputation of the e-liquid brand matters. Reputable brands, prioritize high-quality ingredients and may work with trusted flavouring houses.


While the sweetness in some e-liquids doesn’t come from sugar, it can be attributed to the natural sweetness of VG, flavourings, and optional sweeteners. Understanding the composition of e-liquids allows vapers to make informed choices and appreciate the diversity of flavours available. Opting for e-liquids from reputable brands ensures a higher standard of quality and transparency in ingredients.
