Vegetable glycerine is one of the main components of an e-liquid. It produces a lot of vapor, but doesn't carry the flavours very well. The higher the VG content, the thicker the e-liquid and the greater the vapor, and the less flavour is delivered. Before using a liquid with a high VG content, check that your equipment can withstand it (large liquid inlets), otherwise your coil may suffer repeated dry hits.
