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 50VG / 50PG liquids, which will provide a medium throat hit, and requires less power to vaporise. This is the most common mixture of liquid for 10ml bottles, and much more suitable for MTL (mouth to lung) starter kits.
