Question on throat hit?

[Lastlokean]

I'm a little confused on the 'throat hit' idea. For me an e-cig is seems to be either going perfectly smooth and delicious or harsh and vile tasting.... (aka Dry hitting?)

Is it just because most of my juice is at least 50% VG? I have a range of flavors, nic strength and a range of 50pg/50vg to 100 vg mixes...

With my really tart flavors like rockstar and sweet tart I can assuredly feel a tart tingling all the way through my lungs and throat... (not sure if this is the same idea?)

The throat hit from an analogue tingles the throat mildly and I don't really feel it in the lungs...

On devices I usually use an ego-c or ce4+ v1 / stardust v3 with the long wicks. The ego-c on average seems to work better but occasionally goes through a dry hit period on and off where it tastes very acrid and unpleasant. (Quite certain there may be acrolein / glycerin decay at this point.) The stardust seems like it doesn't dry hit often but never really produces flavor or vapor like my ego-c does...?

I have a 10 pack of 1.5 ohm Black dual coil cartomizers with 510 threading from vaporcrave but all I really seem to taste out of any carto is a bad substrate poly-fill flavor... This device usually causes me to cough, its not that the vapor is more or more dense or dry hitting. Is this what people call throat hit?

Do any of you other newbies out there prefer a low to no throat hit also? From a chemical stand point if the throat hit people experience isn't from heat what is it? At first I thought throat hit was glycerin pulling water out of membranes. Now I'm not so sure that it isn't something else.

Rant end...

Throat hit comes from a few different things 1 being nicotine (higher mg = more TH) 2 being PG (higher pg = more TH) and 3 being how warm the vapor is. (warmer vapor = more TH) Hope this helps.

Nicotine is the main cause of throat hit. More nic more throat hit. High VG can mute throat hit to some degree. More wattage will intensify the throat hit from the nicotine.

In addition to Dana, FlavourArt has a Flash liquid that mimics the throat hit of nicotine. It works pretty well! I use it now that I am at 0 mg (After a year of vaping and stepping down my nicotine every 3 months or so). This may be more of an advanced bit of information, but it is relevant nonetheless.

I'm kinda like you. I'm in the mild throat hit camp. Too much and it seems to overwhelm the flavor for me.
Depending on what I'm vaping, I either go with LR or SR (2.0 ohm or 2.5 ohm) cartos and stardust's to control that.
When I vape a juice that gives a lot of TH, then I up the resistance of the carto or stardust.

Nicotine is the main cause of throat hit. More nic more throat hit. High VG can mute throat hit to some degree. More wattage will intensify the throat hit from the nicotine.

In a nutshell, this explanation hits the mark. Higher nicotine content enchanced through warmer vapor (better battery PV's) is what creates throat hit. PG lets more of the TH through, VG mutes it. A better description of true throat hit is the "inhaled feel" of an analog. Additives to eliquids such as PGA or pepper do not provide throat hit independent of the nicotine strength. They can provide throat irritation and burning which is not the same as throat hit. Menthol provides the feel of menthol, just like it did in menthol analogs. A different feel than throat hit.

The way I look at it, PG is the optimal vehicle to transport the throat hit from nicotine. At one time I thought PG was the cause of throat hit because everyone keep saying more PG = more throat hit but they didn't explain why exactly. I'm not sure if it is because of the thickness of VG which is what I'm guessing but it drags down the throat hit from nicotine.

On the whole PG / VG thing I used to think PG carried a lot more 'throat hit' also. Until I've started experimenting with the temperature of my vaping experience. I noticed that PG requires a much lower temperature to boil and its flash point isn't far from its boiling point. As such I have been playing with huge coils of 30 gauge to get to 6-8 ohms and using 8 - 12 v power supply. I find at 8 volts and 8 ohms is 8 watts and gives off PLENTY of smooth vapor. Compared to 100% PG at 4V and 2 Ohm(also 8 watts) the vapor production is about the same but my god this is so harsh I can't even inhale it.

As you can see in my two examples above both running at 8 watts do not have the same temperature.

If you look up Nichrome heat charts current and wire gauge directly control surface temp of wire. TBH I think current technology on the market is overheating / scorching juice... I'm not talking about 'wattage' here I'm talking about actual temperatures being reached at any 'hot spot' within an atomizer.
