Vegetable Glycerin (VG)
VG stands for Vegetable Glycerin. It is a natural chemical, derived from vegetable oil, so is safe for vegetarians. It is commonly used in e-liquid to give a 'thick' sensation to vapour. VG has a slightly sweet taste and is considerably thicker than PG. The hit from a high VG fluid is a lot smoother than with PG, making it more suitable for sub-ohm vaping. While nicotine and flavourings are commonly suspended in PG, some vendors are offering a VG alternative, to enable 100% VG mixes.
