Rhubarb & Custard Longfill E-Liquid Concentrate by Nixer x Double Brew

Rhubarb & Custard Longfill E-Liquid Concentrate by Nixer x Double Brew is a British sweet jar staple, and this version keeps the rhubarb genuinely sharp.

Flavour Profile

Tart rhubarb arrives first, green and mouth puckering, with none of the boiled sweet softness these blends usually settle for.

Thick custard follows and smothers the sharpness in vanilla richness, finishing warm and comforting.

What A Longfill Is

Sold as concentrate, this 60ml bottle contains 30ml of nicotine free flavour and nothing else. The empty half is where your base and nicotine go.

Pour in a Nixer Mixer Kit, shake, and you have a full 60ml bottle ready to use. It is the cheapest route to a big bottle of a flavour you already know you like, and you choose the strength yourself.

How To Mix It

• Step one. Remove the cap and the nib from the top of the concentrate bottle.
• Step two. Add the full contents of a Nixer Mixer Kit, all three bottles of it.
• Step three. Replace the nib and cap, then shake the bottle well for one minute.
• Step four. A short steep is optional, but most blends taste rounder after one.

Mixer Kits come in two shapes. The nic salt version lands at a 50% VG blend and suits pod kits and starter kits; the freebase version lands at 70% VG for sub ohm kits. Both are sold with and without ice.
