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 100VG liquids, these are specially formulated to not contain any PG as a small minority can have a PG intolerance. These liquids should be used with 100% VG nic shots if nicotine is required to keep them PG free. This type of liquid is more suitable for sub-ohm kits, as the VG ratio is too high for most MTL (mouth to lung) kits.
