What is vg and pg

Last updated: April 1, 2026

Quick Answer: VG and PG are the two primary base ingredients in e-liquid for vaping. VG (Vegetable Glycerin) produces more visible vapor, while PG (Propylene Glycol) carries flavor more effectively and provides a stronger throat hit.

Key Facts

VG stands for Vegetable Glycerin, a thick, sweet liquid derived from vegetable oils
PG stands for Propylene Glycol, a thin, odorless liquid commonly used in pharmaceuticals and food products
VG-heavy liquids (70% VG or higher) produce denser clouds but less throat sensation
PG-heavy liquids provide stronger flavor and throat hit but less visible vapor
Most e-liquids use a blend of both VG and PG, with ratios like 50/50, 70/30, or 80/20 depending on user preference

VG and PG Explained

VG and PG are the fundamental base liquids in every e-cigarette or vaping product. These two ingredients make up approximately 90% of any e-liquid, with nicotine and flavorings comprising the remaining 10%. Understanding the difference between these two components helps vapers choose products that match their preferences for vapor production, flavor intensity, and throat sensation.

Vegetable Glycerin (VG)

Vegetable Glycerin is a thick, naturally sweet liquid derived from vegetable oils. In vaping, VG is responsible for producing visible vapor clouds. Higher VG concentrations create denser, more impressive clouds of vapor. VG has a slower absorption rate in the atomizer, making it ideal for sub-ohm vaping devices that support larger amounts of liquid. Because VG is naturally sweet, it can slightly sweeten the overall taste of e-liquid.

Propylene Glycol (PG)

Propylene Glycol is a thin, odorless liquid that serves as a carrier for flavor compounds in e-liquid. PG carries and delivers flavor more efficiently than VG, resulting in more pronounced taste. It also provides the "throat hit" sensation that mimics the feeling of smoking traditional cigarettes. PG is absorbed quickly in atomizers, making it suitable for standard vaping devices. Many vapers appreciate PG-dominant liquids for the intense flavor experience they provide.

Finding Your Perfect Ratio

The ideal VG/PG ratio depends on individual preferences. Cloud chasers typically prefer 70/30 or 80/20 ratios for maximum vapor production. Flavor enthusiasts may choose 50/50 or 60/40 ratios to prioritize taste. Beginners often start with 50/50 blends as a balanced option. Some users with sensitivity to PG prefer higher VG ratios, while others find lower VG ratios harsh on their devices. Experimenting with different ratios helps determine your personal preference.

Aspect	VG (Vegetable Glycerin)	PG (Propylene Glycol)
Viscosity	Thick, heavy	Thin, light
Vapor Production	High - dense clouds	Low - minimal clouds
Flavor Delivery	Muted, less intense	Strong, more intense
Throat Hit	Mild sensation	Strong sensation
Best For	Cloud chasing, sub-ohm	Flavor, throat sensation
