VG vs PG Basics

Vegetable Glycerin (VG) and Propylene Glycol (PG) are the base liquids for e-liquid. VG produces more vapor and is sweeter, while PG carries flavor better and provides throat hit.

  • High VG (70%+): More vapor, smoother, slightly sweet
  • Balanced (50/50): Good balance of flavor and vapor
  • High PG (70%+): Stronger flavor, more throat hit, less vapor

Safety Precautions

  • Always wear gloves and safety glasses when handling nicotine
  • Work in a well-ventilated area
  • Use accurate measuring equipment (syringes or scales)
  • Store nicotine base in childproof containers
  • Label all bottles clearly with contents and date
  • Never mix nicotine strengths above 50mg/ml without professional training

Frequently Asked Questions

What VG/PG ratio should I use?
70/30 VG/PG is popular for sub-ohm vaping with high vapor production. 50/50 works well for standard devices and pod systems. Higher PG ratios provide more throat hit and flavor but less vapor.
How much flavoring should I use?
Most flavor concentrates work well at 10-20% of total volume. Start lower (5-10%) and adjust to taste. Some potent flavors may only need 1-5%. Always follow manufacturer recommendations.
Can I mix different nicotine bases?
Yes, but it complicates calculations. This calculator assumes one nicotine base type. If mixing VG and PG nicotine bases, you'll need to calculate each separately.
How long should I steep my e-liquid?
Steeping allows flavors to blend. Most e-liquids benefit from 1-2 weeks of steeping in a cool, dark place. Shake daily. Fruit flavors need less time than complex dessert or tobacco flavors.
