Buying Guide: Key Purchase Considerations
- Ingredients and purity: Prioritize products with all-natural ingredients if you prefer minimal synthetic additives. Check if the product lists both natural and artificial flavours to understand flavour intensity and profile.
- Nicotine content: Decide whether you need nicotine-free options or a base for nicotine-containing blends. Nicotine-free products are suitable for testers and flavour exploration without nicotine exposure.
- Format and application: Sprays are convenient for precise flavour finishing in small batches; liquids are better for DIY e-liquid bases and direct mixing. Consider your workflow and equipment.
- Base composition: For DIY bases, a balanced VG/PG ratio helps with vapor production and throat hit. A 70/30 VG/PG mix is common for many devices, but adjust to your device and preferences.
- Certifications and sourcing: Look for USP-grade, food-grade ingredients when available, and consider products produced in a manner that aligns with your quality standards.
- Compatibility with devices: Some flavour concentrates are designed for general use in e-liquids, while others are better as aroma sprays or finishing flavours. Ensure compatibility with your device type and coil.
Frequently Asked Questions
- What is the best base ratio for DIY e-liquids? A common starting point is 70% VG / 30% PG, but adjust based on device, coil, and desired throat hit.
- Are sprayable flavours safe for vaping? Sprayable flavours are designed for finishing or aroma applications; use caution and follow product guidelines to avoid over-saturation.
