Just found out this morning the impact of the so-called 'PG/VG Ratio'.
PG is Propylene Glycol, that good old antifreeze and general purpose food additive. If it were harmful in minute amounts we'd all be dead; it's in pretty much every kind of processed food there is.
VG is Vegetable glycerin, which is chemically similar but comes from vegetables instead of petroleum. Before we run off down the road of which is safer, who really knows; it's likely moot, as the amounts are microscopic in the trace amounts absorbed from the vape.
ANYWAY. Their physical properties are vastly different, and they each contribute unique characteristics to the vapor. VG is much more viscous (thicker). It contributes volumes of vapor, at the expense of being a good flavor vehicle. PG carries the flavor well, but produces far less vapor, and provides what is referred to as 'throat hit'. Throat hit makes it more like that punch in the throat and upper chest that one gets from a cigarette; for myself, I prefer less of that. Throat hit makes me cough after 35 years of analogs; but that's just me, to each his own.
This is why most juices are neither straight PG or straight VG, and this is what you want to tweak in your juice recipe to get more of the character you want to see in the final product
Happy vaping!
