Good--but not excellent for Vaping [SEP] I use VG for vaping.<br />Have been mixing my own juices since 2007 when vaping started.<br />The quality of VG and PG is very important, otherwise I will start coughing.<br /> My point of reference is essential depot's VG and PG. Their quality is top notch, although their prices are higher.<br />VG should taste sweet, and have no other residual taste apart from the sweetness. If you taste any bitterness behind the sweetness, do not use it for vaping.<br />This VG is sweet but I can taste a faint aftertaste mixed up in the sweetness, which makes me think it's not USPS food grade. On another note, I am not coughing, which tells me it's ok to vape.
