For vapers, E-Liquid VG/PG are ubiquitous terms on product bottles—but few fully comprehend how these two core ingredients define their vaping experience. Overlooking their role often leads to lackluster results: overly dry throats, thin vapor, or muted flavor. Understanding them (Vegetable Glycerin and Propylene Glycol) isn’t just technical knowledge; it’s the foundation for choosing an e-liquid that aligns with your device, preferences, and comfort.
What Are E-Liquid VG/PG? Core Definitions
These two base liquids form the backbone of all e-liquids, and their properties directly shape every aspect of your vape:

- Vegetable Glycerin (VG): A plant-derived component: odorless, naturally sweet, and thick. It’s prized for producing dense, voluminous vapor clouds.
- Propylene Glycol (PG): The synthetic counterpart: flavorless, thin, and exceptional at carrying flavor molecules while delivering a smooth throat hit.
Ratios: How They Impact Your Vape
The ratio of VG to PG dictates three key elements: vapor production, flavor intensity, and throat hit. Choosing the right balance hinges entirely on your device and personal preferences:
High VG (70% VG/30% PG or Higher)
Ideal for sub-ohm devices (low resistance, high wattage) and cloud chasers. This blend delivers thick, billowing vapor and a mild, sweet throat hit. While vapor production is prioritized, flavor may be slightly softer due to VG’s viscosity— a tradeoff many cloud enthusiasts embrace. It works best with devices that require ample liquid flow to prevent dry hits.
High PG (60% PG/40% VG or Higher)
Tailored for pod systems, pen-style vapes, or mouth-to-lung (MTL) devices—setups that mimic the tight draw of a cigarette. This ratio leverages PG’s thin consistency to carry flavor with precision, resulting in crisp, vivid taste. It also delivers a satisfying throat hit, a key preference for former smokers. Note: High PG may irritate sensitive throats or cause dry mouth in some users.
50/50: The Versatile Middle Ground
Perfect for beginners or vapers who want balance. A 50/50 blend offers moderate vapor, decent flavor clarity, and a gentle throat hit. It adapts seamlessly to most devices—from basic pods to entry-level sub-ohm kits—making it a low-risk choice for those still exploring their preferences.

Key Considerations for Comfort & Compatibility
- Sensitivity: VG is gentler on airways, making high VG blends ideal for those with PG sensitivities or dry throat issues.
- Flavor Pairing: VG’s natural sweetness complements dessert, fruit, or candy flavors. PG’s neutrality lets tobacco, menthol, or savory notes shine.
- Device Compatibility: Thick high VG liquids can clog narrow pod coils. High PG blends may cause dry hits in sub-ohm devices due to rapid absorption.
How to Choose the Right Ratio
Follow this simple framework to nail your choice without guesswork:
- Identify your device type (sub-ohm = high VG; MTL/pod = high PG).
- Prioritize your goal: cloud production, bold flavor, or balanced comfort.
- Test ratios if unsure—start with 50/50, then adjust based on your experience.
VG and PG aren’t just passive ingredients—they’re the building blocks of a personalized vaping experience. By understanding their unique properties and how ratios interact with your device and preferences, you’ll move beyond generic e-liquids and select blends that feel custom-tailored. Vaping is about enjoyment, and mastering E-Liquid VG/PG basics is the first step to consistent, satisfying hits.
