Watermelon Ice E-Liquid Recipe

Ingredients (for 30mL of e-liquid):

• Base (VG/PG Mix):

  • Vegetable Glycerin (VG): 70%
  • Propylene Glycol (PG): 30%

• Flavor Concentrates (Eirhorse):

  • Watermelon: 8% (2.4mL)
  • Ice/Cool Effect (Eirhorse Menthol or Koolada): 2% (0.6mL)

• Sweetener (Optional):

  • Sucralose or ethyl maltol: 1% (0.3mL)

• Nicotine (Optional):

  • Adjust based on desired strength. For example, to make 3mg/mL, use 0.9mL of 100mg/mL nicotine solution.

Mixing Instructions:

1. Safety Precautions: Wear gloves and work in a ventilated area, especially if handling nicotine.
2. Using syringes, add the following to your mixing bottle in this order:
   • Nicotine (if used)
   • Eirhorse Watermelon concentrate
   • Eirhorse Menthol/Koolada concentrate
   • Sweetener (optional)
   • PG
   • VG
3. Cap the bottle tightly and shake well for 2–3 minutes to ensure the ingredients mix thoroughly.
4. Let the mixture steep for 2–3 days, as fruit and menthol blends don't require long steeping times. Shake the bottle daily during steeping.
5. Test the e-liquid after steeping and adjust the flavor or cooling effect if needed. Add more menthol or watermelon in small increments if required.

Customization Tips:

• More Ice: For an extra icy hit, increase the menthol or Koolada to 3%.
• Tartness: Add 1% Eirhorse Sour to enhance the watermelon’s natural tang.
• Richer Watermelon: Blend Eirhorse Watermelon with a hint (1-2%) of Strawberry or Melon to create depth.

This recipe will deliver a juicy, sweet watermelon flavor with a refreshing icy exhale—perfect for hot days or anyone who loves menthol-fruit combinations! Let me know how it turns out! 🌬🍉
