Longfill and shortfill both describe nicotine-free vape juice sold in a bottle with room left over for nicotine. The difference is the flavour concentrate: longfill uses a stronger one, so you get a bigger bottle of finished vape juice from the same amount of flavour. If you run a vape shop or you are new to mixing your own juice, this is the one distinction worth getting right.
This article is for adults aged 18 and over.
What is shortfill?
Shortfill is ready-to-vape, nicotine-free e-liquid sold in an oversized bottle that is not completely full. The empty space lets you add nicotine shots to reach the strength you want. The juice inside is already mixed and balanced, so it tastes the way it is meant to as soon as you shake it.
What is longfill?
Longfill is a flavour concentrate, also nicotine-free, sold in a bottle that is only part full. It is more concentrated than shortfill, so there is a lot of space to top up. The bottle is built for easy topping up with either nic salts or freebase nicotine, plus a base liquid if needed.
Vapology’s 60ml longfill bottles are nicotine-free and formatted for easy top-ups with either Nic Salts or Freebase Nicotine.

Which one is better?
Neither is better in every case. Shortfill is simpler. Longfill gives more value per bottle and more flexibility, which is why it suits regular vapers and busy shops. What matters is that you read the bottle: each brand states how much nicotine to add and what final strength you get. Follow the instructions on the label.
What this means if you run a vape shop
- Explain it at the counter. Customers often use the two words interchangeably. A two-line explanation and a clear shelf label reduce returns and questions.
- Stock the nicotine to match. Longfill sells with nic salts and freebase shots. Keep both on the shelf and recommend the pairing that suits the customer’s device.
- Choose one size to start. Vapology’s refill range is currently available in 60ml, with an improved 120ml formula coming soon, so ranges can be planned around the 60ml bottle now.
- Choose branded, barcoded stock. Retail-ready bottles with barcodes and clear labelling are quicker to ring up and easier to display.
