The big question of the day...What is short fill e-liquid?

For a product that first emerged some time ago, we find that a lot of people still don’t quite know the distinction between the different types of e-liquid available.

Most Vapers will have come across “short fill” at one point or another. Whether you realise it or not, it’s sold widely across most vape shops and websites and is a great alternative for your vaping needs.

Whether you think you’ve heard of short fill, you’re a pro-vaper or are completely unsure as to what short fill e-liquid is, follow our guide within this article, where we’ll simplify the do’s, don’t and how’s, as best as we can.

What Are Shortfill E-Liquids All About?

What short fill e-liquid is, is a means to an end.

At Orange County CBD, we realise that vaping and e-liquid regulations are changing at a “blink and you’ll miss it” rate.

That’s where we step in, to dot the i’s, cross the t’s and cut through the tricky stuff for you.

Read on to learn some distinct differences between short fill e-liquid and boost shots. 

Short Fill vs Boost Shots: What Are The Differences?

The differences are instantly clear, when it comes to bottle size and design, but look a little closer and you’ll see their functionality also differs.

We’ve listed some of the key differences below:

Boost Shots:

Boost shots can contain either CBD or nicotine.

CBD Boost Shots:

  • Larger bottles as large as 100ml
  • Usually, flavourless
  • CBD content ranging 100mg – 1000mg

Nicotine Boost Shots:

  • Smaller bottles, no more than 10ml
  • Can be flavourless
  • Nicotine content ranging from low to high, usually between 6mg-20mg

Short Fill:

  • Large bottles, usually ranging from 60ml-100ml
  • 0% CBD and nicotine content
  • Wide range of flavours to mix with depending on your preference

What Are Shortfill E-Liquids Used For & Why?

Short fill e-liquids first came into fruition as a means of getting around the Tobacco Products Directive’s (TPR) restrictions on e-liquid bottle capacity, for e-liquids containing nicotine.

What short fill e-liquid does, is a dilution process. Short fill e-liquids come in a large bottle, filled only partially with 0mg nicotine/CBD e-liquid.

This leaves enough space for you to pour between one and two 10ml bottles of high-strength e-liquid into your short fill bottle.

Enabling you to balance out the overall nicotine strength of the e-liquid to the level that you desire places a new level of control into your hands.

Let’s put it into practical terms, to help you gain a better understanding:

If you add 10ml of 18mg (nicotine) e-liquid to 50ml of short fill 0mg (nicotine) e-liquid, you’ll be left with 60ml of 3mg e-liquid.

Equally, you will need to be mindful of the levels of CBD boost shot you put into your short fill.

Who Are Shortfill E-Liquids For?

Firstly, short fills are for those of you wanting to save as much money as possible. Per 10ml of e-liquid, short fills have the lowest comparative price, due to the ability to buy bottles of greater quantities.

However, the low nicotine content e-liquid created (once mixed) will perhaps not preferable for a more hardened vaper who is accustomed to a certain strength of CBD or nicotine in their vaporiser.

Whether you vape nicotine e-liquid or cbd e-liquid, whether you prefer vaping Mouth to Lung (MTL) or Direct to Lung (DTL), or whether you just want to try something new, shortfill e-liquid’s suitability for you all depends on your own individual, personal preference.

Below are our top 3 benefits of using short fill e-liquid.

  • It’ll save you money in the long run – with larger bottles, the value for money is much greater and you’ll save in the long run. (Just don’t forget that short fill is 0% CBD/nicotine)
  • They’re quick and easy to mix - once you’ve got the hang of it!
  • No carrying around lots of small 10ml bottles – save on clutter, only rely on remembering one bottle and reduce the chances of losing smaller, less easily noticed bottles.

Why Do Some Vapers Prefer Shortfill?

Vapers prefer short fill e-liquid for numerous and individually differing reasons.

Combined with the aspect of convenience, as listed above, it also allows vapers to engage with their creative side, mix various flavours together to invent and create their own e-liquid concoctions.

Allowing Vapers to become their own vaper mixologist turns the simple form of inhaling vaper into a culinary inspired art form, where creating becomes part of the experience.

Similarly, vapers can create an e-liquid as weak or as strong as they please by utilising this method.

Although these qualities are part of what makes short fill e-liquid fun, please act cautiously.

It is not advisable to vape e-liquid stronger than 20mg of nicotine or to consume more than 70mg of CBD per day, in alignment with the government guidelines.
