I'm just getting into the DIY game, and I've noticed that some of my flavors are getting more harsh after steeping for about two weeks. When they come out, they're not too bad, I'm using the steam-engine juice calculator and consistently mixing them at a 70/30 at 3mg and my nicotine is a 48mg PG base from liquid barn. Any tips or reasons why this is happening?
Harshness in juice could be caused by any number of factors. It could be the quality of nic you use, liquid barn is used by a lot of people but I'm not sure if juice companies use it. I've personally found it to be harsher than other brands of nic. Also, it could be flavors, and the companies producing them. If you get a lemon flavoring from TFA or Capella, they will both be harsh from the citrus, but one might be sweeter and less harsh. The last thing I could think of would be sweetener. It tends to harshen juices if used in large quantities. Usually I do mine in drops (sucralose.) If you're using sweetener, rule of thumb is to use one drop for every 5 or 10 mls of e-liquid.
Thanks for the great reply. I forgot to add that I've mainly been noticing this is happening with my fruity/melon flavors, I'm not using any sweeteners, and oddly enough my orange banana recipe which is heavier on the citrus doesn't suffer from this problem. I'll try changing up my nicotine and see if that makes a difference! Do you have any recommendations?
Are you using Liquid Barn flavors
I have a few Liquid Barn flavors. I really like their honeydew, orange banana and white chocolate peppermint, but other than that, no.
Are all your mixes coming out harsh?
No, after tasting all of my juices it seems that only a few were coming out harsh, the melon was one of them. I think it might be a LB thing to have harsh melons or something. It wasn't bad enough to the point where I was unable to vape it, however it took a minute to get used to it.
Here is an excellent post regarding reasons your juice may be harsh and how to figure out the cause.
PG is harsher than VG. There's no reason to use it unless you have an atomizer designed for juice that's thinner than pure VG. My ancient kayfun is like this, I brew 70/30 for it, and full VG for everything else. High wattage can also make it too harsh.
I'm with Diogenes on this one. PG sucks and max VG can carry flavor just fine. Over the years I've personally settled on 90/10 as my preferred ratio.
are you’re flavorings held in PG?
Well, personally I only add PDO or PEG400 to my mixes if I'm using flavors that need more flavor carrier content (mainly tobacco).
Still, you can't assume the OP isn't into pain, like Krauz said. So the most likely issue is... how was the mix steeped? Any chance the nic oxidized (ie: used a mechanical frother type gizmo, mixed into a container such that it was half air and then shook the fuck out of it, left it in the grow tent with the UV lights on, etc)?
Is mixing into a half empty bottle bad? I accidentally ordered 60mls instead of 30s for my first order and since I didn’t wanna waste materials on my first brews, I have several 30’s steeping in the 60ml bottles right now.
