E-Liquid is made from two main base ingredients, Propylene Glycol and Vegetable Glycerine (PG / VG). These are mixed in various ratios, depending on the liquid that you buy, alongside with food grade flavourings and nicotine if you choose to have any. The higher the VG, the smoother the vaping experience. This page displays our 80VG / 20PG liquids, which will provide less of a throat hit due to the higher ratio of VG. This type of liquid is more suitable for DTL (direct to lung) sub-ohm kits, as the VG ratio is too high for most MTL (mouth to lung) kits.
