Squeezing your own juice

Preamble

Making your own eJuice… seeing as commercially available eJuice is expensive, so why not DIY?

In this article I will outline the basics of making eJuice, and go through four preparation methods.

Resources and links

Quick Nic list

To make 3 mg/ml nicotine eJuice, using 72 mg/ml nicotine concentrate, for the following quantities:

  • 30 ml of eJuice requires 1.2g ml of 72mg/ml nicotine
  • 40 ml of eJuice requires 1.67g ml of 72mg/ml nicotine
  • 50 ml of eJuice requires 2.083g ml of 72mg/ml nicotine
  • 100 ml of eJuice requires 4.167g ml of 72mg/ml nicotine
  • 150 ml of eJuice requires 6.25g ml of 72mg/ml nicotine
  • 450 ml of eJuice requires 18.75g ml of 72mg/ml nicotine
  • 500 ml of eJuice requires 20.83g ml of 72mg/ml nicotine

Obviously, to make stronger eJuice then increase the amount of nicotine concentrate accordingly, using the following multipliers:

  • 6 mg/ml  = x2
  • 9 mg/ml = x3
  • 12 mg/ml = x4
  • 18 mg/ml = x6

Making your own DIY vape juice

Putting it very simply, there are three basic constituents in eJuice:

  • Glycerol (PG:VG), see PG vs VG;
  • Nicotine;
  • Flavouring.

Looking into it in a bit more depth, the two main constituents to eJuice are:

  • PG – Propylene Glycol, and;
  • VG – Vegetable Glycerin

as well as:

  • Flavourings
  • Nicotine
  • Thinning – distilled water

Proportions/ Ratios of PG to VG

Vapor:

  • Less vapor – PG – Stealth vaping
  • More vapor – VG – Cloud chasing

Hit:

  • For a throaty hit – increase PG ratio
  • For more smoothness – increase VG ratio

Other points:

  • PG wicks better
  • PG carries flavours better
  • PG can causes irritation
  • Steeping – Juice with a high VG% needs steeping longer than higher PG%

Flavouring

From Bakewell Tart E liquid Flavour Concentrate DIY Vape Juice Flavouring

Mixing a juice is about personal taste and customising the flavour to what you like.
Put simply use between 5% to 20% of flavourings.
When I make my own, I smell the flavourings to get an idea of how strong the flavouring is. If it smells strong I use 5%, weak 15% and I test and add more if needed.

Nicotine

From Where to buy pure nicotine liquid?

Do not under any circumstances attempt to buy pure nicotine. It is a lethal poison at that strength.

It is not a substance that can be handled safely without the proper training and equipment.

Please be like the rest of us happy, safe DIY’ers and buy maximum of 100mg (10%) nic. As mentioned already 60mg is more than enough for DIY mixing. Even 100mg is illegal in the UK.


Methods of Preparation

I will go through four methods of preparation. They are somewhat similar, with minor variations between them. Some methods may suit certain people more than others.

Method 1

Use the Steam-Engine calculator, here: Steam-Engine – Juice

Method 3

The method that I like most, and find simplest, is the same as method 2, except that – as I always use 3 mg/ml (0.3%) nicotine eJuice – I simply make a big bottle of VG/PG mix with the 3 mg/ml nicotine also in it. Then, as needed, I make smaller 150 ml bottles of flavoured eJuice, by adding flavouring to the empty bottle and then topping the bottle up, using the base from the big bottle. I find this way easier, as I find it more efficient and easier to mix the nicotine into a big batch of PG/VG mix, rather than in a smaller bottle. Some people might say that the nicotine will deteriorate whilst sitting in the PG/VG mix, but so long as you keep it refrigerated, there should not be a problem.

The procedure is as follows:

  1. First, make a big 500 ml, or 1000 ml, mix of PG/VG first,  See below for the ratios and quantities required.
  2. Then add, to the 500 ml bottle, the amount of nicotine needed to make the 3 mg/ml concentration, and shake it well.
  3. Store this bottle of base (unflavoured) eJuice in the refrigerator until required.
  4. Then, for the smaller, more manageable quantity of, say, 150 ml eJuice, first add, into the 150 ml bottle (I use Worcester sauce bottles), the quantities of flavouring required (as detailed in Method 4).
  5. Finally top up the rest of the bottle, i.e. to the 150 ml mark, with the PG/VG mix that you made in step 1.

An alternative method, to ensure that the nicotine concentrate is well dispersed within the mix, is to:

  1. make a PG/VG mix in a one litre bottle first, and shake well, to mix the PG and the VG.
  2. Then, from the one litre bottle, half fill the 500 ml bottle (i.e. add 250 ml of PG/VG mix).
  3. Then add the nicotine for a 500 ml mix and shake well.
  4. Then add the remaining 250 ml of PG/VG mix, and shake well again.
  5. Repeat steps 2, 3 and 4 for the other 500 ml bottle
  6. You now have two 500 ml bottles of PG/VG and nicotine mix

You will need:

  • 1 x 1 litre bottle
  • 2 x 500 ml bottles

Method 2

Another method that I like, and find simple, is to:

  1. First, make a big 500 ml, or 1000 ml, mix of PG/VG first, and store that in the refrigerator until required. See below for the ratios and quantities required.
  2. Then, for the smaller, more manageable quantity of, say, 150 ml eJuice, first add, into the 150 ml bottle (I use Worcester sauce bottles), the quantities of nicotine and flavouring required (as detailed in Method 4).
  3. Finally top up the rest of the bottle, i.e. to the 150 ml mark, with the PG/VG mix that you made in step 1.

Ratios and quantities required

40 ml

You want to make 40 ml of PG/VG mix, let’s say.

PG & VG

First mix your PG and VG is the ratio that you require, that is the easy part:

  • For 70:30, you need 28 ml of PG and 12 ml of VG
  • For 50:50, you need 20 ml of PG and 20 ml of VG
  • For 30:70, you need 12 ml of PG and 28 ml of VG

Note that, to be strictly accurate with your final quantity and ratios, you will need to subtract the amount of nicotine and flavouring that you are going to add from the total amount that you want, in this case 40 ml, in order to give you the correct amount of PG/VG mix.

100 ml

You want to make 100 ml of PG/VG mix, let’s say

First mix your PG and VG is the ratio that you require, that is the easy part:

  • For 70:30, you need 70 ml of PG and 30 ml of VG
  • For 50:50, you need 50 ml of PG and 50 ml of VG
  • For 30:70, you need 30 ml of PG and 70 ml of VG

Note that, to be strictly accurate with your final quantity and ratios, you will need to subtract the amount of nicotine and flavouring that you are going to add from the total amount that you want, in this case 100 ml, in order to give you the correct amount of PG/VG mix.

150 ml

Let’s say you want to make 150 ml of PG/VG mix,

  • For 50:50, you need 75 ml of PG and 75 ml of VG
  • For 30:70, you need 50 ml of PG and 100 ml of VG

Note that, to be strictly accurate with your final quantity and ratios, you will need to subtract the amount of nicotine and flavouring that you are going to add from the total amount that you want, in this case 150 ml, in order to give you the correct amount of PG/VG mix.

450 ml

You want to make 450 ml of PG/VG mix, let’s say

  • For 50:50, you need 225 ml of PG and 225 ml of VG
  • For 30:70, you need 135 ml of PG and 315 ml of VG

Note that, to be strictly accurate with your final quantity and ratios, you will need to subtract the amount of nicotine and flavouring that you are going to add from the total amount that you want, in this case 450 ml, in order to give you the correct amount of PG/VG mix.

500 ml

You want to make 500 ml of PG/VG mix, let’s say

Method 3

From How to Make E-Juice – Welcome to your DIY adventure

Quick Nic list

  • 30 ml of eJuice requires 1.2g ml of 72mg/ml nicotine
  • 40 ml of eJuice requires 1.67g ml of 72mg/ml nicotine
  • 50 ml of eJuice requires 2.083g ml of 72mg/ml nicotine
  • 100 ml of eJuice requires 4.167g ml of 72mg/ml nicotine
  • 150 ml of eJuice requires 6.25g ml of 72mg/ml nicotine
  • 450 ml of eJuice requires 18.75g ml of 72mg/ml nicotine
  • 500 ml of eJuice requires 20.83g ml of 72mg/ml nicotine

30 ml

You want to make 30 ml, let’s say.

Nicotine

You have 72mg/ml nicotine

You want to make 30 ml of 3 mg/ml eJuice

So you need 30 ml x 3 mg/ml = 90 mg of nicotine

90/72 = 1.25 ml of 72 mg/ml diluted nicotine

40 ml

You want to make 40 ml, let’s say.

Nicotine

You have 72mg/ml nicotine

You want to make 40 ml of 3 mg/ml eJuice

So you need 40 ml x 3 mg/ml = 120 mg of nicotine

120/72 = 1.67 ml of 72 mg/ml diluted nicotine

Flavour

5-10% flavour should be used, so for 500 ml, you need 2 – 4 ml of flavour, so let’s say 2.8 ml, using a 7% of concentrate, for a subtle flavour. A stronger 20% flavouring will require 8 ml of flavour concentrate.

VG/PG

We already have 4.47 ml of nicotine and flavouring, for a 7% flavouring mix, so we need 35.53 ml, that is 17.765 ml of each PG and VG for a 50/50. For a 20% flavouring mix, we will have 9.67 ml of flavouring and nicotine, so we need an additional 30.33 ml, so roughly 15 ml of PG and VG.

Or, for 70/30 VG/PG then that is 24.871 ml of VG and 10.659 ml of PG for the 7% flavour mix

Don’t forget though that 1.67 ml is already PG (or VG), as the nicotine was in PG (or VG). So the ratio will not be exactly 70/30 but more like XXXX????

100 ml

You want to make 100 ml, let’s say

Nicotine

You have 72mg/ml nicotine

You want to make 100 ml of 3 mg/ml eJuice

So you need 100 ml x 3 mg/ml = 300 mg of nicotine

300/72 = 4.167 ml of 72 mg/ml diluted nicotine

Flavour

5-10% flavour should be used, so for 500 ml, you need 5 – 10 ml of flavour, so let’s say 7 ml, using a 7% of concentrate, for a subtle flavour. A stronger 20% flavouring will require 20 ml of flavour concentrate.

VG/PG

We already have 11.167 ml of nicotine and flavouring, for a 7% flavouring mix, so we need 88.833 ml, that is 44.4 ml of each PG and VG for a 50/50. For a 20% flavouring mix, we will have 24.167 ml of flavouring and nicotine, so we need an additional 75.833 ml, so roughly 38 ml each of PG and VG.

Or, for 70/30 VG/PG then that is 62.1831 ml of VG and 26.6499 ml of PG for the 7% flavour mix

Don’t forget though that 4.167 ml is already PG (or VG), as the nicotine was in PG (or VG). So the ratio will not be exactly 70/30 but more like XXXX????

150 ml

Let’s say you want to make 150 ml

Nicotine

You have 72mg/ml nicotine

You want to make 150 ml of 3 mg/ml eJuice

So you need 150 ml x 3 mg/ml = 450 mg of nicotine

450/72 = 6.25 ml of 72 mg/ml diluted nicotine

Flavour

5-10% flavour should be used, so for 150 ml, you need 7.5 – 15 ml of flavour, so let’s say 10 ml, using a 7% of concentrate, for a subtle flavour. A stronger 20% flavour would require 30 ml.

VG/PG

We already have 16.25 ml of nicotine and flavouring, for a 7% flavouring mix, so we need 133.75 ml, that is 66.875 ml of each PG and VG for a 50/50. For a 20% flavouring mix, we will have 36.25 ml of flavouring and nicotine, so we need an additional 113.75 ml, so 56.875 ml each of PG and VG.

Or, for 70/30 VG/PG then that is 94 ml of VG and 40 ml of PG for the 7% flavour mix

Don’t forget though that 6.25 ml is already PG (or VG), as the nicotine was in PG (or VG). So the ratio will not be exactly 70/30 but more like XXXX????

450 ml

You want to make 450 ml, let’s say

Nicotine

You have 72mg/ml nicotine

You want to make 450 ml of 3mg/ml eJuice

So you need 450 ml x 3 mg/ml = 1350 mg of nicotine

1350/72 = 18.75 ml of 72 mg/ml diluted nicotine.

Flavour

5-10% flavour should be used, so for 500 ml, you need 22.5 – 45 ml of flavour, so let’s say 30 ml, using a 7% of concentrate, for a subtle flavour. A stronger 20% flavouring will require 90 ml of flavour concentrate.

VG/PG

We already have 48.75 ml of nicotine and flavouring, for a 7% flavouring mix, so we need 401.25 ml, that is 200.625 ml of each PG and VG for a 50/50. For a 20% flavouring mix, we will have 108.75 ml of flavouring and nicotine, so we need an additional 341.25 ml, so 170.625 ml each of PG and VG.

Or, for 70/30 VG/PG then that is 282 ml of VG and 120 ml of PG for the 7% flavour mix

Don’t forget though that 18.75 ml is already PG (or VG), as the nicotine was in PG (or VG). So the ratio will not be exactly 70/30 but more like XXXX????

500 ml

You want to make 500 ml, let’s say

Nicotine

You have 72mg/ml nicotine

You want to make 500 ml of 3 mg/ml eJuice

So you need 500 ml x 3 mg/ml = 1500 mg of nicotine

1500/72 = 20.83 ml of 72 mg/ml diluted nicotine

Flavour

5-10% flavour should be used, so for 500 ml, you need 25 – 50 ml of flavour, so let’s say 35 ml, using a 7% of concentrate, for a subtle flavour. A stronger 20% flavouring will require 100 ml of flavour concentrate.

VG/PG

We already have 55.83 ml of nicotine and flavouring, for a 7% flavouring mix, so we need 444.165 ml, that is 222.08 ml of each PG and VG for a 50/50. For a 20% flavouring mix, we will have 120.83 ml of flavouring and nicotine, so we need an additional 379.165 ml, so 189.5825 ml each of PG and VG.

Or, for 70/30 VG/PG then that is 310.9155 ml of VG and 133.2495 ml of PG for the 7% flavour mix

Don’t forget though that 20.83 ml is already PG (or VG), as the nicotine was in PG (or VG). So the ratio will not be exactly 70/30 but more like XXXX????

 

Results

This 150 ml mix tasted awful. Reasons why:

  • Apparently, after contacting the supplier, 20% flavouring should be used, so 30 ml and not 8 ml. The flavouring that I used was this Bakewell tart from thisseason_online. I have purchased 30 ml more, and will add an additional 20 ml of that when it arrives and see how the flavour improves.
    • To the weak Bakewell art mix, I ended up adding 10 ml more, and not 20 ml as I had originally intended. The flavour was subtle, not strong, but acceptable.
    • As I had put a total of 20 ml in 150 ml, this gives a ratio of 13.33%, therefore 33.33 ml in 250 ml should be sufficient. Following this guide, I made another mix, 250 ml, into which I put 30 ml of Bakewell Tart mixture – so I added, roughly, 220 ml of 70/30 VG/PG 3 mg liquid. Again, the flavour was a little on the weak side, but subtle and acceptable.
  • I had not let it steep. Before adding extra flavouring I left the mix steeping for a couple of days. The smell had definitely appeared to improve over night. I did not try it again at this strength. However, once more flavouring had arrived, I added 10 ml more of bakewell tart (not 20 ml) and the taste of the resulting mix, again, whilst not strong, was pleasantly tinged with bakewell tart flavour.
  • I also added 2ml of Gummy Bear, for the same supplier, to 8-10 ml of some 50/50 3 mg mix and the flavour could be sensed, also, it still was not strong – also I vaped it immediately after mixing, no steeping occurred. However, after leaving for a while, the flavour had improved, and whilst still not strong, was extremely pleasurable. I now go with the 20% rule for the gummy bear and custard (new custard link) flavourings from this supplier.
    • Likewise for the Bakewell tart, if you like a subtle flavour then 13.3% is ok, otherwise, if your taste buds require more flavour, I would stick with the 20% as advised, and put 30 ml in 120 ml of PG/VG to give 150 ml of eJuice.

Other flavourings suppliers

Now, while the Bakewell tart additive probably is a lovely flavour, it maybe not as strong, or concentrated, as others. Reading this thread, Will any old food flavouring do?,  it suggests Liberty Flight, and their FlavourArt flavourings, which are £3.29 for 10 ml and only 2 to 5% use is suggested, so they could be cheaper. However, shipping is £1.49

Direct from FlavourArt, £5 (offer, normally) for 50 ml, but with £4.12 shipping, although at £9 (£1.8/10ml) still cheaper than Liberty Flight, as £9 worth, from Liberty Flight, would only give 30 ml (£3/10ml). Buying three 50 ml bottles on offer, brings the price down even further to £19.12 (£1.27/10ml)

Compared with the flavourings from thisseason_online, which is £5.99 for 30 ml + Free shipping (£2/10ml), FlavourArt directly is cheaper. Also, after having tried the UP and Apricot flavourings, once my order had arrived, I found them to be ridiculously concentrated (in a good way) and only one or two drops were required, as opposed to 2 ml, for a 10 ml mix.

Again with the FlavourArt flavourings, I made a couple of 150 ml mixes, in 150 ml Worcester Sauce bottles:

  1. With the Tiramisu I added enough to just cover the ring of glass at the bottom of the bottle, maybe 2%? 15 drips
  2. With the Apricot, I added more, enough to come up to 1 cm from the bottom base of the bottle which is about 10 cm high (to the shoulder of the bottle), so allowing for the thickness of the bottle base (3-5mm), I would say just under, or around, 5%. Around 30 drips of flavour
  3. With the UP, again I added enough to cover the ring of glass at the bottom of the bottle, so around 2%, again 15 drips.

I was also recommended DarkStar and Totally Wicked, by a chap in a pub…

UPDATE: After further experimentation with FlavourArt’s flavours, I found that 15 drops in a 150 ml bottle gave a subtle taste, whilst doubling to 30 drops gave a more fuller flavour. So, between 1 – 3 drops per 10 ml.

I purchased some more FlavourArt’s flavouring (Gin, Guava, Fig, Rhum, Walnut, and Peanut), and I found that 9 drops of Rhum in 30 ml of PG/VG was quite strongly flavoured, maybe overly so. 6 drops of Walnut in 30 ml of PG/VG was nicely flavoured, just right

Making repairs – adjusting the PG/VG ratio

If you have make a mix that isn’t in quite the right proportions of PG to VG that you would like, and you want to increase the proportion of VG, how do you fix that?

Assuming that you have 3 mg, 50/50 VG/PG, then for 100 ml:

  • adding 20 ml of VG gives 60/40 VG/PG
  • adding 40 ml of VG gives 65/35 VG/PG
  • adding 50 ml of VG gives 66/33 VG/PG
  • adding 75 ml of VG gives 71/29 VG/PG
  • adding 100 ml of VG makes 75/25 VG/PG

However, this will obviously reduce the nicotine. So, for:

  • 25 ml of 3mg 50/50 mix, with an added 25 ml of VG, you will need to add 1 ml of 72mg/100ml nicotine, to maintain the 3 mg/100ml nicotine content. Results in 50ml 75/25 VG/PG.
  • 50 ml of 3mg 50/50 mix, with an added 50 ml of VG, you will need to add 2 ml of 72mg/100ml nicotine, to maintain the 3 mg/100ml nicotine content.
  • 100 ml of 3mg 50/50 mix, with an added 100 ml of VG, you will need to add 4 ml of 72mg/100ml nicotine, to maintain the 3 mg/100ml nicotine content.
  • 225 ml of 3mg 50/50 mix, with an added 225 ml of VG, you will need to add 9 ml of 72mg/100ml nicotine, to maintain the 3 mg/100ml nicotine content. Results in 450ml 75/25 VG/PG.
  • 250 ml of 3mg 50/50 mix, with an added 250 ml of VG, you will need to add 10 ml of 72mg/100ml nicotine, to maintain the 3 mg/100ml nicotine content.. Results in 500ml 75/25 VG/PG.

Using stronger nicotine

If you can get hold of 100mg/ml, or 200mg/ml, nicotine, then obviously the amount you need to use will be a lot less.

For 100mg/ml you will need to put:

  • 3 ml for 100 ml of 3 mg/ml eJuice (instead of the 4.167 ml of 72 mg/ml nicotine)
  • 4.5 ml for 150 ml of 3 mg/ml eJuice (instead of the 6.25 ml of 72 mg/ml nicotine)
  • 7.5 ml for 250 ml of 3 mg/ml eJuice (instead of the 10.42 ml of 72 mg/ml nicotine)
  • 13.5 ml for 450 ml of 3 mg/ml eJuice (instead of the 18.75 ml of 72 mg/ml nicotine)
  • 15 ml for 500 ml of 3 mg/ml eJuice (instead of the 20.83 ml of 72 mg/ml nicotine)

For 200mg/ml you will need to put:

  • 1.5 ml for 100 ml of 3 mg/ml eJuice (instead of the 4.167 ml of 72 mg/ml nicotine)
  • 2.25 ml for 150 ml of 3 mg/ml eJuice (instead of the 6.25 ml of 72 mg/ml nicotine)
  • 3.75 ml for 250 ml of 3 mg/ml eJuice (instead of the 10.42 ml of 72 mg/ml nicotine)
  • 6.75 ml for 450 ml of 3 mg/ml eJuice (instead of the 18.75 ml of 72 mg/ml nicotine)
  • 7.5 ml for 500 ml of 3 mg/ml eJuice (instead of the 20.83 ml of 72 mg/ml nicotine)

Storing the nicotine mix

Main points:

  • Store at 0°C
  • Do not shake
  • Keep out of sunlight
  • Store in amber bottles
  • Do not leave bottle open
  • Get nicotine that is in 100% PG solution – PG has a longer shelf life than VG

This implies that while steeping, it may be best not to add the nicotine until the steeping process is finished. However, the nicotine also needs to be steeped, and will add a peppery taste (see Steeping and adding nicotine later and Adding nicotine after steeping).

From Properly storing nicotine:

Nicotine WILL NOT degrade if it is 100% pure and nitrogen sealed in dark glass bottles and kept at a low temperature. That’s how professional labs keep it so it’s as close as a fact as you will get when it comes to nicotine storage! Obviously you aren’t going to be able to achieve all those criteria at home (you wont have 100% pure nicotine being the main one) BUT majority of us could accomplish two of those important criteria.

Once you add other chemicals such as PG or VG into the bottle and can’t remove all the oxygen then degradation occurs. At what rate and the effect is open to question as no one has actually kept PG or VG nicotine base in a freezer for more than about 5 years so far but it will degrade to some degree even if you do keep it in your freezer. The issue really is with the oxygen either from air trapped in the bottle or through energy put into the chemical system via light (UV) breaking down the dilutant (PG or VG), which unfortunately being organic compounds have oxygen in their make up. It’s fine normally because the oxygen in the dilutant is attached to a hydrogen, making a diol (O-H) and will not compete for the nicotine but if you add energy into the system the one single covalent bond between the oxygen and the hydrogen can be broken and you have the issue of the spare oxygen running around causing problems. This is the reason to keep the nic base in amber glass bottles and is the same reason that nicotine is kept nitrogen sealed in labs – so there are no spare oxygen atoms. Keeping the nicotine base at low (freezer) temperatures also slows down the movement of the molecules, which obviously slows down any chemical reactions.

Oxygen is nicotine’s main enemy,
Oxygen converts it to nicotine oxide in an oxidation reaction and nicotine oxide being a charged molecule has free electrons, this is why the colour change occurs (free electron movement between the atomic energy levels). These free electrons can also target other substances in e-liquid such as flavourings and changes their chemical structure, which coincidentally is the reason why e-liquid has a shelf life.

Storage Basics
Always buy the highest % nicotine base you can buy (currently 7.2% legally in the UK) as the less PG/VG you have in the bottle the better and always buy the best quality, freshest base you can find to start off with.

What to store it in?
Nicotine base should be stored in dark amber glass bottles to stop UV degradation and potential chemical leaching caused by plastic bottles.

How to store it?
Depending on your usage if you bought 1 litre+ bottles then you should decant it into smaller quantity bottles containing the amount you would probably use in 3 or 4 months so that you aren’t exposing the majority of the nicotine base to more oxygen every time you want to use it. Once you open a bottle it’s best to store it in a fridge if possible rather than just a shelf at room temperature and ALWAYS out of sunlight. It is worth noting that PG nicotine base remains fairly free flowing even straight out of the freezer but VG base turns into a gel and will need several hours at room temperature to be useable.

Where in the freezer to store it?
Purely from a safety point of view it is best to store it at the bottom of the freezer so that if it does leak it doesn’t contaminate anything else in the freezer. I know that some people have a separate freezer for their nicotine base but plenty just stick it in with rest of the families shopping! Make sure that the bottle is clearly labelled, not for you but for the other people using the freezer. If you have young children it would be very wise, if not essential, to buy a small freezer to keep in the garage or similar just for your nicotine stocks.

What’s better, PG or VG as the Dilutant ?
A personal preference really but with regards to degradation then VG has an extra O-H functional group (3 compared to 2 in PG) so it is possible that if degradation did take place it would be quicker in the VG. However VG has a better shelf life than PG, 2 years compared to 1 year generally AND VG’s viscosity works in it’s favour for once as the more viscous a liquid the less the molecules move about …… so it’s probably 6 of one half a dozen of the other really as to which is best!

How long will it last?
It would be expected to possibly see and experience noticeable degradation after 5 -10 years storage either in taste or colour. Strength drop would need chemical analysis once someone has stored it for that long to determine but it is believed by many that it won’t be anywhere near half.

What not to do
Leave the bottles alone! The less they are disturbed the better. DO NOT open the bottles if you don’t need to and never shake them as this introduces oxygen to more of the nicotine base rather than just the surface.

More price comparisons

Flavour Art prices

FlavourArt has 50 ml bottles of flavourings on offer at £5, which are normally priced at £8, or £12 for the more blended flavours.

  • 50 ml @ £5 = £0.10/ml
  • 50 ml @ £8 = £0.16/ml
  • 50 ml @ £12 = £0.24/ml

For an order of £30 (or more) you currently get a free 50 ml bottle of the delicious “UP!”. So, for some example orders, including the cost of postage:

Order of £50

With post £37

6 cheap bottles + UP = 37/7 = 5.286 per 50 ml bottle = £0.1056/ml

Order of £50

With post £57

10 cheap bottles +UP = 57/11 = 5.18 per 50 ml bottle = £0.1036/ml

Order of £60

With post £67

12 cheap bottles + UP = 67 / 13 = 5.15 per 50 ml bottle = £0.103/ml

Two orders of 30 gives 14 bottles for £74 =  = 5.286 per 50 ml bottle = £0.1056/ml

However, there are only 12 flavours, 1 I already have and two are tobacco

Dark Star prices

DarkStar stock a number of different suppliers’ flavours, FlavorWest (FW) and Dark Arts are the cheapest:

  • FW = 30ml @ £3.50 = £0.117
  • DA = 30 ml @ £4.00 = £0.133

So, for some example orders, including the cost of postage:

  • 5 bottles FW @£17.50 + £ 1.49 = 18.99 for 150ml = £0.1266/ml
  • 5 bottles DA @20.00 + £ 1.49 = 21.49 for 150ml = £0.1433/ml
  • 4 bottles DA & 1 bottle FW @£19.50 + £ 1.49 = 20.99 for 150ml = £0.1399/ml

How much nicotine (and what strength) should you buy?

I have found that when vaping heavily, 100 ml of 72 mg/ml lasts me around three months. By that measure a litre would last 30 months (maybe two and a half years). Therefore a litre of 200 mg/ml nicotine would provide enough eJuice for roughly 7.5 years!
