Since the TPD (Tobacco Products Directive) has come into effect, manufacturers have found a clever new way of producing e-liquid in bottles larger than 10ml - these are known as short fill bottles. These bottles can be any size (normally 60ml, 100ml or 120ml) and have free space in the bottle for a nicotine booster to be added. The short-fill e-liquid itself is nicotine-free, and the basic idea is to add your required strength of nicotine as a shot in the top of the bottle, then shake to combine the two. A 120ml short-fill bottle will contain 100ml of juice, leaving 20ml of space for 2 nicotine boosters - resulting in a 120ml mixed bottle. 60ml bottles will contain 50ml of juice, leaving 10ml of space for the nicotine to be added.

For example, if you are used to a nicotine content of 3mg, then simply add one 10ml 18mg bottle of nicotine solution to 50ml of e-liquid. For 100ml of e-liquid then it would require 2 bottles of nicotine. Once the nicotine is added to the e-liquid you will need to seal and then shake the bottle for around 4 - 5 minutes to ensure that the nicotine has been mixed in. If possible, it is advised to do this more than once and leave the liquid for 24 hours to ensure it has mixed correctly.

We have included a table below to show you in simple terms how much nicotine needs to be added to the short-fill for a bottle of 3mg.

60ml (contains 50ml)

1 x 10ml 18mg(1.8%)

60ml of 3mg

120ml (contains 100ml)

2 x 10ml 18mg(1.8%)

120ml of 3mg

The bottles come with a secure plastic cap which can be removed with either a small screwdriver or set of pliers. Once the nicotine has been added, please ensure that the plastic cap is put firmly back in place to avoid spilling any liquid.

Vaping Outlaws are one of the ranges that have just been re-released in 60ml and 100ml short fill bottles and I would honestly check these flavours out as they are amazing. A personal favourite would be Four Horsemen which is dessert-based liquid with prominent flavours of vanilla, cream and cake.

I hope this has been helpful and remember just because the TPD is in place, you don’t have to just buy 10ml bottles of e-liquid.

Happy vaping!
