PG ratio - Flavour adjust co-efficient

Hey guys,

Does anyone done any work on a flavour co-efficient for PG ratio.

E.g. IF flavours are 10% for a 50/50 mix - and that is perfect if I change the PG/VG to 75/25 what should the Flavours percentage be now 7.5% - the co-efficient would be 0.1% flavour decrease for every 1% increase in PG.

Anyone got some work on this? I made a batch of the Bust-a-nut and found it overwhelming. I like a 50/50 mix and Alisa has max VG. So would be interested to have a number I can plug in to adjust he flavours.

Another question would arise, does flavour strength increase equally across flavours when increasing PG too?

Good idea! In my limited experience, flavours will react differently to changes in PG level. So it’s likely there isn’t a hard and fast ratio, although it might give you a general idea how much to adjust.

exactly, flavour perception is such a wide variable anyway. So if we can come up with a median kind of number we could use that to make adjustments. It’s going to be more accurate then doing nothing!

Anybody have some data, run some experiments, batches on this?

I asked that very same question a while back and someone posted this in the thread.


I haven’t actually used it myself as I’m just sticking to what it says in recipes until I find my way and actually know what I’m doing. I hope this is useful.

Thanks Doc!

Well I plotted those points as I could tell the methodology didn’t look quite right as you can see in my plots. The sheet you supplied is plotted in the top graph (you can see the points sort of don;lt make sense they are not consistent some above the line some below. I assumed that the co-efficient is linear and plotted that below. The co-efficient according to the spreadsheet is 0.5

So basically according to that if you increase your PG by 20 on a recipe times your percentages by (20x0.5) = 10% and add that on top. If you decrease you subtract.

Be cool to have a parameter in our personal settings you could default it to 0.5 and have afunction on the recipe to adjust PG or not according to the co-efficient.

Cool huh! That way people could even put there own co-efficient in. It would be super awesome if you allowed exponential equations for the advanced and people could put curves into their adjustments if they preferred. What do you think.

These features sound like a lot of work to implement them here - for something that wouldn’t necessarily make a big difference anyway. It’s a game of numbers, but in reality it’s more complicated than that. I used to mess around with single flavours and 60/40, 50/50, 20/80 PG/VG ratios, what I found was that it differs from flavour to flavour what ratio works best for them.

On a side note, I think that spreadsheet is by @CosmicTruth.

No not a huge amount of work. Especially if they have the adjust flavour percentage function it would be similar. The rest of your points are spot on.

What happened to “Good idea” in post #2, I can definitely seem some benefit especially for the noobs. I’d imagine that when you adapt a recipe, it checks how different your PG ratio is to the original and asks if you wish to adjust flavouring for PG ratio difference or not. Simples.

Personally I’d really like it. Obviously others go to the extent of making spreadsheets to do the task , so to add it in would be awesome. However, in regards to priorities of changes I have no idea about that. Is it a must have upgrade. No, but i’d love to see it on the to-do list priority unknown.Definitely not a write off though.

Is there a forum where discussions about suggestions for the recipe builder live?

That one is not mine, I have seen that one but couldn’t translate it into my native language (typo). I have considered working with those calculations for flavor adjustments for PG/VG and Nicotine but most folks think it does not make a difference. My limited research led me to believe increasing VG increases sweetness, Increasing PG increases flavor, and if Nicotine is increased a slight increase in flavor may be needed to help mask the Nicotine. But for me I don’t do a formal calculation I just wing it when I abduct a recipe and the tester tastes bland or overly flavored.

Oops…

Love that wording btw :laughing:
