People always say there is diminished flavor with all VG but I love it. The thing is though, I have not tried the same exact flavor in different PG/VG. My 70/30 liquids are from a different company vs my All VG and ?PG/VG (Johnson Creek). It's all about finding your taste. Start with a small sample kit. I made the big mistake of buying alot of small samples in search of an amazing one. Thankfully just 3mL bottles, but now I'm trying to find anyone in my city to take them. Good luck in the Hunt!
 
Never noticed a difference. Glad to see this topic come up though. I have trouble having ANY flavor after about a day of mixing a couple of flavors together that I enjoy. I've bought all different combos of PG/VG, increased flavor, and purchased flavoring only to increase it, but no luck. I'm getting the impression that PG alone is the best for holding flavor. Even though I've been at this for almost four years, I don't know about the term "steeping." Can someone explain or is that taking this off-topic. (Still bemused that I've found myself having lost all my posts and a new member again!) I lost any throat-hit ages ago.

In the simplest ways it's letting the smoke juice sit untouched for a couple days, or even a whole week after vigorously shaking it. Other people prefer to start it by having it uncapped for 24-48 hours. For most flavors I let them sit 3 days, but the ones that struck me as overwhelming when I vaped, I uncap.

steeping with use of a fan

you can also
use an old computer fan and a stainless steel bearing
or small stainless screw

Yep, VG requires more flavoring than PG. VG is easier to inhale than PG for most, VG is less drying than PG for most, PG has more throat hit than VG for most, VG makes more vapor than PG, VG is thicker (more viscous) than PG and adverse reactions to PG are more common than VG.

Can you say that three times in a row fast ?

I knew exactly what I wanted. Just shocked at the flavor once home. I'll try again in a few days. Best damn coffee I ever had, so I'm horribly anxious.

Oh, coffee.

Coffee really is a funny one for me when it's the primary flavour. I always start out liking them, then finish up hating them. It also seems to be the one that non-vapers around you can smell and identify very easily.

I tried a caramel capuccino and loved it at first. After the first day the caramel just tasted like a burning carto to me.

Next I tried a straight coffee. Tastes like a strong black coffee, very nice. Then I discovered it gets really old after about two hits. I can vape it after that, but there's no joy in it.

What I _did_ find however is that the straight coffee flavour is just great for resetting the palate. You know when you've been vaping all day at work and it's all just tasting the same blah? Two hits of coffee fixes it. Testing new flavour concentrates and you hit one that just ruins your palate so you can't tasting anything BUT the really nasty flavour you just OD'd on? Coffee fixes that too. Same for after eating food that makes the normal vape taste weird.

I keep a little clearo of that coffee with me at all times for when I need it, but it will never be something I want to vape for any length of time. If you've got coffee flavours that you really liked in the store, but find you don't like them after two or three hits at home I can certainly relate to this.

I want to add a note against the general concensus for 50/50 PG/VG too. Playing around with mixing a few flavours and wanted to try my usual 80/20, 70/30 etc all the way up to 50/50 because I was curious. I got to 60/40 and found the VG was starting to give the vape a heavy oily taste. I settled on 70/30 which gives good vapour and throat hit, without messing with the flavour too much at all.

I guess you'll just have to try it.

What in the blazes?

Heh, the lengths some people will got to. That probably isn't the best thing to show someone wanting to know what it's all about.

It's about flavours blending chemically and maturing. It's a very complex subject which any of us can only hope to dabble in and hope for good results. The reason is that we have no control over the actual reactions taking place, and can't know exactly what happened even when it works well.

When you mix a new juice you'll often find the colour is quite light. Over time (days or weeks) the colour usually goes a little darker and the taste matures.

The main ingredient is time, however many will try to accelerate things a little using agitation, heat, and exposure to the air. The mechanisms are complex and probably different for different flavours in different combinations but probably involve flavour molecules reacting with each other to make more complex molecules. Somtimes this will hide a flavour, and sometimes it will change or increase it.

Agitation probably does two things - it might activate the molecules and increase the rate of reaction but mostly I suspect it forces the air in the bottle into suspension, giving the comounds more access to the oxygen in it. This might increase the rate of oxidation and some of the complex chemicals involved may even require this process. Different batches maturing at different rates and giving different results may just come down to how much air was in the bottle. There was talk about larger bottles (100ml) of Boba's Bounty tasting different to the 30ml bottles. This might be due to the fact that there would be a smaller percentage of air in the 100ml bottle compared to the juice/air ratio in the 30ml bottle. One fact that seems to indicate that oxidation is occuring in this process is that mixed liquids will go darker with time. This is often an indicator that oxidation is occuring.

Exposure to heat (ie a hot water bath that the bottle are placed in) probably speeds up the process by increasing the rate of chemical reactions. There's probably good scientific reason to think that heating the juice will make it mature faster, and in fact this can be used in wine production where it is required for the wine to reach maturation faster (not for boutique or classic wines however!). Even well made wines will undergo a pastuerisation process (to kill the yeast) these days, and the manufacturers may not be keen on telling you that this might be force maturing the wine also.

Exposure to the air probably just allows fresh oxygen to contact the liquid and increase the rate of oxidation, same as for agitition. Common sense tells us that if we are agitating to force air into suspension, then letting the juice breathe to replace the oxygen in the bottle is probably a good idea as well.

Which brings us to the fan. Personally, I believe it's probably largely an oxidation process, so while the fan with work to keep the air in suspension it doesn't allow for replacement of the air in the bottle for fresh.

A last word about oxidation and flavourings:
Oxidation isn't always a good thing. There are many things in nature that taste worse when oxidised (bananas, apples, potatoes etc) and others that are improved (can't think of examples but I know they exist). Since were're not chemists we can't really know what is going to happen when we steep (or 'age' if you want the more typical term used for potables) except to try by trial and error and see what happens.

I just mixed up a batch of a smokey cherry cigar that I'm working on. The colour was very light, about like a light honey colour and stayed like that all afternoon. I hadn't agitated it at all. A few hours ago I gave it a good airing out and shake up, and the reaction was almost immediate - the colour went about two shades darker in about half an hour. I'm going to compare it to a batch I made made up ealier and see if it's showing the same changes in taste as well.

theres a guy on youtube this is his steeping genius idea

agitation and oxygen inoculation, obviously air/oxygen taste great
any dripper knows this fact
just take a look at vg or pg's specific gravity
this is not the best way to mix e juice but for a quick agitation its the bees knees
