What is a Shortfill E-Liquid?

A shortfill e-liquid is a bottle of liquid containing no nicotine. They are usually found as 50ml of e-liquid in a 60ml bottle or 100ml of e-liquid in a 120ml bottle, hence the name shortfill. The additional space in the bottle is designed to give enough space for the 10ml bottle of unflavoured nicotine (Nic shot.)

There are laws in Europe that prohibit the sale of nicotine containing bottles over 10ml in capacity, this is due to the TPD (Tobacco Products Directive). The TPD does not cover 0mg or nicotine free liquids, bringing a rise to the popularity of shortfill e-liquids.
