What Are PG and VG?

If you're into vaping or DIY e-liquid mixing, you've probably encountered the terms PG and VG. Understanding these two base liquids is essential for creating the perfect vape experience.

Propylene Glycol (PG) is a colorless, odorless liquid that serves as one of the main carriers in e-liquids. It's known for providing a stronger throat hit similar to smoking traditional cigarettes, and it carries flavor exceptionally well. PG has a thinner consistency, making it easier to wick in most vaping devices.

Vegetable Glycerine (VG) is a thicker, slightly sweet liquid derived from vegetable oils. It's responsible for producing those big, satisfying clouds that many vapers love. VG provides a smoother, less intense throat hit compared to PG.

The PG/VG Ratio Formula

The PG/VG ratio tells you the relative proportions of these two liquids in your e-liquid mixture. The formula is straightforward:

[\text{PG/VG Ratio} = \frac{\text{Total PG Volume (ml)}}{\text{Total VG Volume (ml)}}]

This ratio helps you understand and replicate your preferred vaping characteristics.

Calculation Example

Let's work through an example to see how this works in practice.

Given:

  • Total Propylene Glycol (PG): 90 ml
  • Total Vegetable Glycerine (VG): 150 ml

Calculation:

[\text{PG/VG Ratio} = \frac{90}{150} = 0.60]

This means for every 1 part VG, you have 0.6 parts PG. In percentage terms, this would be roughly a 37.5% PG to 62.5% VG mix, which leans toward more vapor production with a smoother throat hit.

Interpreting Your Ratio

  • Ratio = 1.0: Equal parts PG and VG (50/50 mix) - balanced throat hit and vapor
  • Ratio < 1.0: More VG than PG - smoother, more vapor, less throat hit
  • Ratio > 1.0: More PG than VG - stronger throat hit, better flavor, less vapor

Tips for Finding Your Perfect Ratio

  1. Start with 50/50: If you're new to vaping or mixing, a balanced ratio provides a good baseline experience.

  2. For stronger throat hit: Increase the PG proportion (higher ratio) - good for those transitioning from cigarettes.

  3. For bigger clouds: Increase the VG proportion (lower ratio) - ideal for sub-ohm vaping and cloud chasing.

  4. Consider your device: Pod systems often work better with higher PG ratios, while sub-ohm tanks handle high VG better.

  5. Watch for sensitivities: Some people are sensitive to PG. If you experience irritation, try higher VG ratios.

Frequently Asked Questions

Propylene Glycol (PG) is a colorless, odorless liquid commonly used in e-liquids. It provides a stronger throat hit and carries flavor more effectively. PG is thinner than VG, making it easier to wick in vaping devices.

Vegetable Glycerine (VG) is a thicker, sweeter liquid derived from vegetable oils. It produces more vapor and provides a smoother sensation. Higher VG ratios are popular for cloud chasing.

The PG/VG ratio affects throat hit, vapor production, and flavor intensity. Higher PG ratios give stronger throat hit and better flavor, while higher VG ratios produce more vapor and smoother draws.

A 50/50 ratio (ratio of 1.0) is often recommended for beginners as it provides a balanced experience with moderate vapor production and throat hit. Adjust based on personal preference over time.
