Making your own E-Liquid from scratch (DIY E-Liquid) involves using a mix of PG (propylene glycol), VG (vegetable glycerin), concentrated flavourings and nicotine to create your very own personalised recipe!
The majority of E-Liquids contain a mixture of both PG and VG. Both of these ingredients offer different attributes to your E-Liquid, so it can be handy to know plenty about them in order for you to find your perfect balance/ratio of the two.
VG has a thick consistency which provides very little throat hit with large vapour production. E-Liquids with a high VG content (anything above 60% VG) should only be used with high power set-ups because a lot of power/heat is needed to burn thick liquids. Sub Ohm Tanks (tanks that contain atomisers with a resistance below 1.0 Ohms) paired with high powered mods (20 Watts+) are the ideal setup for high VG liquids.
PG is the thinner, less viscous liquid of the two bases. E-Liquids with high PG content (50% or higher) are compatible with most tanks/clearomisers on the market. PG is the ingredient in E-Liquid that provides the throat hit (aside from the nicotine). The more PG you add, the harsher the liquid will be on your throat when you take a ‘puff’.
The most common nicotine concentrations in DIY E-Liquid are 3mg and 6mg. This is the case even more so now the TPD Regulations have come in and changed the strength of raw nicotine from 72%/mg to 18%/mg. This means realistically you can’t make your E-Liquid higher than 16mg.
Undiluted liquid nicotine is a poison even in small amounts, please handle with extreme caution. Use protective clothing, gloves and goggles to ensure no contact is made with skin or eyes. If any contact is made with skin or eyes ensure you thoroughly wash affected area with water for at least 15 minutes. If you feel unwell seek medical attention immediately.
When making your own E-Liquid you need to have a desired VG/PG ratio in mind. The more VG you use the thicker and smoother the liquid is going to be. The more PG you use the thinner and harsher your liquid will be when you vape it. The ratio simply refers to the percentage of PG in the mix compared to the percentage of VG in the mix. For example, an 80vg/20pg ratio means the E-Liquid is made up of 80% VG and 20% PG. It’s important to remember that everything that goes into the E-Liquid contributes towards this ratio; your flavouring is a PG base, while your nicotine can be purchased in either a PG or a VG base. Some common ratios are:
30vg/70pg - strong throat hit, low vapour production (can be used in all tanks/clearomisers)
50vg/50pg - moderate throat hit, moderate vapour production (can be used in all tanks/clearomisers)
60vg/40pg - mild throat hit, good vapour production (can be used in all tanks/clearomisers but is better in tanks capable of being put on 20W+)
70vg/30pg - weak throat hit, large vapour production (can only be used in sub ohm tanks)
80vg/20pg - very weak throat hit, very large vapour production (can only be used in sub ohm tanks)
If you are using a Sub Ohm Tank it’s recommended you have your liquid smooth with less of a kick because these tanks make E-Liquid seem much harsher. Higher VG ratios such as 70vg/30pg or 80vg/20pg are recommended. This is the same for nicotine; the strength of the nicotine is amplified by sub ohm tanks, so you’re probably not going to want to go higher than 6mg. Bare in mind that not everyone is the same and some people like their liquid harsher than this.
If you are using a standard clearomiser you’re going to want to make your liquid thinner by using more PG. This is because thick liquids aren’t compatible with these type of tanks as they are unable to burn the liquid hot enough which clogs and breaks the coil.

-PG and VG
-Protective gloves and goggles
-Calculator (if not using our measurements guide)
If you don't fancy working out exactly how much of each ingredient you will need for your E-Liquid then don't worry, we've done it all for you! View our DIY E-Liquid Calculation / Measurement Guide here: http://www.thebestecigarette.co.uk/diy-e-liquid-calculation/
How to make your E-Liquid
Step 1) Gather all required equipment, put on protective gloves and goggles and have your empty E-Liquid bottle ready.
Step 2) Once you have your desired VG/PG ratio in mind, start by adding your chosen flavour concentrate. We recommend adding 15% for most fruit & dessert flavours, however this varies due to personal preference. The 15% refers to filling 15% of your mixing bottle with the concentrate (not using 15% of your overall concentrate). We recommend a 100ml bottle because it makes all the measurements a lot easier: in a 100ml bottle 15% of concentrate equates to 15ml. Remember that the flavour concentrate is a PG Base, so if you use 15% this contributes to 15% PG in your overall VG/PG ratio. You can use personal judgement to add your concentrate, e.g. if you are aiming to use 15% flavour in a 100ml mixing bottle you can simply add half of your 30ml concentrate. If you would prefer more precise measurements you can use a syringe to add your flavour. If you only have one syringe for all of your ingredients, just make sure you give it a rinse in-between each ingredient to avoid cross-contamination. Mint/menthol & tobacco flavours tend to be a lot stronger so we recommend using a lower percentage for these. Anywhere between 2% - 7% is a good place to start. It's better to start lower and add more later than put too much in to begin with and ruin your whole mix.
Step 3) Add your nicotine. Nicotine shots come in 10ml bottles in a PG or a VG base and are 18mg in strength. If you've not looked at our measurement guides then you will need your calculator to work out how much nicotine you need. First enter your mixing bottle size into your calculator (e.g enter ‘100’ if you are mixing your liquid in a 100ml bottle), then divide this number by the strength of the raw nicotine you are using and press ‘equals’ (the nicotine shots are 18mg so divide by ‘18’). The result will be the amount of Nicotine (in ‘ml’) needed for 1mg nicotine strength. All you now have to do is multiply this number by the strength you would like your overall E-Liquid to be, e.g if you want 3mg E-Liquid then multiply by ‘3’. If you are using a 100ml bottle you would need 16.7ml of nicotine for 3mg. To make it easier you can round this up to 17ml if you wish (it won't make a huge difference). If you trust your personal judgement you can try squeezing the nicotine straight into your mixing bottle, or if you'd prefer more precise measurements you can use a syringe to do it.
Step 4) Once both nicotine and flavourings are added, fill the rest of your bottle with your PG and VG. Quantities of these will vary depending on what consistency and ‘harshness’ you’d like your liquid. VG = Smoother & more vapour. PG = Harsher & less vapour.
Step 5) Once all products are added, put the lid on and shake well.
Tip: Get a bowl of warm water, place closed bottle with mixed ingredients in warm water for 2/3 minutes . This allows the liquid to mix more efficiently . Continue to shake afterwards for an equal amount of time.

Steeping is the process in which you leave your finished liquid to stand so the flavour can develop properly. It is recommended to leave the liquid to stand at room temperature out of the way of any heat, for example in a cupboard.
Depending on which flavourings you have used, steeping time can vary between different flavours.
Desserts and custard flavours take around 2/3 weeks to fully steep. This is because these flavours need plenty of time to develop fully.
Fruits, sweetie and menthol flavours take little to no time to steep fully meaning it is possible to smoke it almost instantly after it has been made. This is something a lot of vapers call “shake ‘n’ vape”.
Once all instructions have been followed carefully your liquid will be ready to vape.
