Two words: Lung Fill.

Nicotine and lung fill are why I vape. Flavor is secondary, throat hit tertiary.

Different strokes.

There is a sort of urban legend surrounding PG that has culminated into mass hysteria with every other vaper claiming he is "allergic" to it. While some people are indeed allergic, the vast majority are not and it's mostly bullshit.

I think some others use it as an excuse so they can blow the biggest cloudz with max VG juice as well.

My absolute most popular flavor I sell locally and sometimes throw in for free with online T-Shirt orders is 99.1% VG, 0.3% nic and 0.6% aroma volatiles. To me it is almost over flavored. I used to add oxidane (water) for wicking but now the label just says "for RDA only, do not use in tanks).

VG is a pain to mix with. But with extended steeping after a run through my homogenizer, and then a follow up homogenization before adding nic, the flavor is solid. This particular flavor needs 6 weeks of steeping in between homogenization runs.

With high VG or 100% VG base, you just need a lot of time and to be extra careful with the heavier base notes.

I recently shipped a few dozen strawberry cake blends to people and that one is less than 2% volatiles but took almost 8 weeks for the cake to appear.

You're right in that higher PG will give you better flavor, but the best heating elements to deliver that flavor (drippers) vastly prefer VG. High PG mixes turn most tanks and RDAs into sieves to my understanding. I don't use high PG because my immune system hates me.

PG sensitivity, irrational (to some extent) fear of PG, and cloud chasers. That's why.

I do 30/70 vg ~~most~~ all of the time with my mixes. I typically have between 7-16% flavor in my mixes. I find that more flavorings tend to run into the over saturated/bland territory.
I don't cloud chase anymore, and am more towards tighter draw drippers and tanks for more flavor, but I still like a little cloud. I settled with the 30/70 as some of the people I sell to use tanks, and some use drippers. I wanted that happy medium.
Thanks for all your posts, I really enjoyed reading the information about flavorings.

Just wanted to say thanks to everyone who took a moment to participate in this thread. The little I know about vegetable glycerin (glycerol, vegetable glycerine) is mostly information gleaned from opinion threads here and there in vaping circles, and five minutes of chemistry / food science research. I learned more about VG in this thread (especially how people use it and why) than all my passive reading on the subject.

I don't have a sensitivity to PG (that I know of), which shows you just how much blinders one can have vs something if they have no ill effects from that thing (where many others do). I should have realised before I posted this that sensitivity to PG would be a prominent reason why many don't like using much of it.

I have been vaping high vg and max VG juices for a couple months now. My friends vape 50v/50p or 60v/40p. When I try their juices I am surprised as to how much smoother it is to inhale. There seems to be way more flavor too. Although I always taste a hint of what I call "chemicals". I don't know what it is, but the best way to describe it is "metallic." They mostly vape fruity creamy flavors, citrus and lemon flavors. Like Fruity pebbles, fruit loops, Mtn Dew, and lemonade. If I vape to much of it I feel kind of ill the next day, like a hang over kind of feeling. I stay hydrated, so I don't know why I feel this way.

Max VG is for us drippers. MAX VG is an amazing thing for a couple of reasons. One, it produces a good thick texture and thick big clouds. If your a super subohm dripper, you don't need to rely on any PG for throat hit, since the heat and amount of vaper from the low builds will achieve this on its own. Also, like you stated it gives a nice sweetness to the mix, which means you don't require any sweetened additives to achieve the same results.... Which is also a major plus to not gunking up your coils so damn fast with all these horrible sweeteners do.

Plus, the Mac VG juice being so thick makes dripping that much more amazing... Throwing some max VG directly on your coils, it stays there in the spots you place it really well. As opposed to higher PG. When you drip onto your coils, it just falls right threw to the bottom of the juice well instantly as if you were pouring water in there. Now I'm now saying max VG just sits on top of your coils, not soaking into the cotton or getting into the juice well.... But it does leave a thicker "taller" amount of juice volume surrounding\coating the coils really well.

Plus, with super subohm dripper builds, a higher PG juice tends to "pop", spit, and launch splatters of none vaporized juice into the users mouth.

We max VG guys due need to shake bottles a lot more, and generally deal with longer steep time; but we still get all the flavor we want. Essentially with some of these flavor companies that only require 3-4% of a flavor to dominate a mix because there so damn strong.

If your rocking a 0.14ohm coil and throw some 50\50 PG\VG juice in there.... Your gonna have a bad time. I won't Vape anything with more than 30% PG in it, and that ratio is typically reserved for my tanks. Plus, PG seems to dehydrate people more than VG. So you gotta stay far more hydrated when vaping higher PG stuff.

I agree flavor is better with pg, buy anything over 30pg just kills my throat for some reason. It really sucks. For a while I though it was just bad nic but even with 0nic high pg blends just hurt

Different strokes for different folks. I personally only vape 70% VG because that's what I enjoy the most. I get enough flavor to my liking, but not too much. The vapor is thicker and the throat hit isn't too much (unlike higher PG mixes). When I switched to rebuildables, I vaped 60% PG and that throat hit wasn't enjoyable.

Also, 70% VG mixes is enough if I feel like cloud chasing, and yet wicks perfectly fine in most tanks. This makes it easier as I don't have to tweak recipes for higher PG mixes, and I don't have to mix at different ratios for diff atties. I can just make my mix that way I always do, and I can vape it in whatever I feel like at the moment.

You have a point tho that for testing flavor concentrates, higher PG is a better idea.

I don't know if I have an official sensitivity to PG, but whenever I vape it at more than 20% I feel bad, generally cold like symptoms. Another thing that I need when vaping isn't clouds, but density. When I vape high PG on a higher wattage it just feels wrong. I am definitely a flavor enthusiast, so I have found that when vaping high VG juices it's all about the build. I find high VG juices to be very muted on standard builds or sub 40 watts. I run a single fused clapton at 60 watts with the bottom airflow and a sliver of side airflow on the Mutation X v4, and the flavor I get is great. Of course this is all subjective, but some of us who are fans of high VG are also fans of flavor.

PG bothers my throat.

Allergies. Irritants. AKA: PG gives me the shits.

There's nothing wrong with having to use a higher % of flavor in a blend with higher VG. Same or similar taste to a higher PG mix with less flavor, but I get to keep my clouds. Also I have a bit of a sweet tooth so higher VG blends let me get that sugar without having to add any other sweetener like sucralose, marshmallow, ethyl maltol and whatnot.

ALSO PG gives me more of a throat hit, and I am not a big fan of throat hit. Out of a 30VG/70PG blend with 5-10% flavor or a 70VG/30PG blend with 15% flavor I am usually going to choose the Higher VG higher flavor combo because at the SAME nicotine level I will get less of a throat hit and the same flavor. Clouds are an added benefit.

TLDR; PG gives too much throat hit, I don't mind using more flavoring, and clouds are really enjoyable.

50/50 all the way for me. It's been my preferred ratio for almost 2 years now. I've used it in a variety of tanks and RDAs, and never had any issues with viscosity. RDAs don't leak if you don't overjuice them. Tanks are more likely to not wick fast enough with high/max VG.

I don't care too much about clouds, but wherever I'm vaping always ends up with the same weather anyway: partly cloudy with a chance of vanilla.

Even with high PG mixes, I was never able to get good flavor from a tank. Soooo, I drip mostly at max VG. I also find that the VG provides enough sweetness for almost all of my recipes.

The tanks only come out when I'm stealth vaping and/or traveling. In those I vape unflavored or some simple one-note flavor like mint.

I've been making juice for over 3yrs and there are two main reasons why I make Max VG. It all started when I was about a year into vaping. I realized that I had a sensitivity to high PG. I would get itchy on my arms and stomach. I didn't realize what it was at first, but I was getting itchy hives on my body and it got quite annoying. I learned about PG sensitivity and decided to switch it up to max VG. As soon as I did that my hives went away. The other reason is because I mostly drip and make juice specifically designed for dripping. By this I mean that the viscosity and flavoring percentages in my juice line are formulated for high heat and high airflow. I'm sure there are a bunch of people that have bullshit claims, but my reasoning is because of itchy hives.

VG has more throat hit, no? I love throat hit, more important than the flavor to me.

I typically only consume organic things. I can get organic VG, PG cannot be organic.

>One thing about VG - it is, in effect, a sweetener for the vape itself

PG is sweeter than VG by the way.
