What Is VG and PG in Vape? The Ultimate Beginner’s Guide to E-Liquid Ratios & Effects

If you’re new to vaping or choosing e-liquid, you’ve probably wondered: what is VG and PG in vape? These two ingredients are the foundation of almost every vape juice on the market, and understanding them can completely change your vaping experience.

In this guide, we’ll clearly explain what VG and PG are, how they differ, what they do, and how to choose the right VG/PG ratio for your needs—whether you want bigger clouds, stronger flavor, or a smoother hit.

What Is VG and PG in Vape? (Quick Overview)

VG and PG are the two base liquids used in vape juice (also called e-liquid or e-juice). They are both:

• Colorless
• Odorless
• Food-grade ingredients

Together, they carry flavorings and nicotine and determine how your vape feels, tastes, and looks.

In simple terms:

• VG = vapor production + smoothness
• PG = flavor strength + throat hit
