PG vs. VG in E-Liquids: Understanding the differences and what’s best for you

Propylene Glycol (PG) and Vegetable Glycerin (VG) are two primary ingredients found in e-liquids, each contributing to the overall vaping experience in unique ways. Understanding the differences between PG and VG can help you choose the right e-liquid composition to suit your preferences and vaping needs. Here’s a breakdown of PG and VG, their characteristics, and how to determine which is best for you:

Propylene Glycol (PG)

  • Characteristics:
    • Consistency: Thinner viscosity compared to VG, making it easier to wick and suitable for most vape turns carts devices.
    • Throat Hit: Provides a stronger throat hit, mimicking the sensation of smoking traditional cigarettes.
    • Flavor Intensity: Carries flavorings more effectively, resulting in more pronounced flavor profiles.
    • Vapor Production: Produces less vapor compared to VG, making it ideal for stealth vaping or those seeking a discreet vaping experience.
    • Allergenic Potential: Some individuals may be sensitive or allergic to PG, experiencing symptoms such as throat irritation or dry mouth.
  • Best For:
    • Flavor Chasers: Vapers who prioritize flavor intensity and throat hit over vapor production.
    • Pod Systems: Devices with smaller coils and lower power outputs, as PG e-liquids are less likely to cause coil gunking or wicking issues.
    • New Vapers: Beginners transitioning from smoking to vaping may prefer PG-dominant e-liquids for their familiar throat hit and flavor delivery.

Vegetable Glycerin (VG)

  • Characteristics:
    • Consistency: Thicker viscosity compared to PG, creating denser clouds of vapor.
    • Smoothness: Provides a smoother inhale and less throat hit compared to PG.
    • Sweetness: Adds sweetness to e-liquids and can slightly mute flavor intensity.
    • Vapor Production: Produces large clouds of vapor, making it popular among cloud chasers and enthusiasts.
    • Hygroscopic: Absorbs moisture from the air, potentially leading to decreased shelf life and thinner vapor in high-humidity environments.
  • Best For:
    • Cloud Chasers: Vapers who prioritize vapor production and enjoy performing tricks or competitions.
    • Direct Lung (DL) Vapers: Users who prefer inhaling vapor directly into the lungs rather than mouth-to-lung (MTL) vaping.
    • Sub-Ohm Devices: High-powered devices capable of handling thicker VG-based e-liquids and producing massive clouds.

Choosing the Right Ratio

  • PG/VG Ratio: E-liquids are typically available in various PG/VG ratios, allowing you to customize your vaping experience.
  • Balance: Finding the right balance between PG and VG depends on your preferences for throat hit, flavor intensity, vapor production, and device compatibility.
  • Experimentation: Start with a balanced ratio (e.g., 50/50) and adjust the PG/VG ratio based on your preferences and device performance.


Understanding the differences between PG and VG in e-liquids is essential for tailoring your vaping experience to your preferences and device capabilities. Whether you prioritize throat hit, flavor intensity, vapor production, or device compatibility, choosing the right PG/VG ratio can enhance your overall satisfaction with vaping. Experiment with different ratios and observe how they affect your vaping experience to find the perfect balance that suits your needs and preferences.
