Longfill: how to mix

What is in the kit

• A bottle with concentrate - usually 60 or 120 ml, filled with flavors to 15-25%.
• Base - a mix of VG and PG, sometimes included, sometimes bought separately.
• Nicotine base - optional, if you want strength. We do not sell nicotine products.

Longfill or shortfill

A shortfill already contains the finished nicotine-free liquid and leaves room for a nicotine shot; a longfill holds only concentrate and needs to be topped up with base. With a longfill you choose the VG/PG ratio yourself.

How to mix a longfill

1. Check on the bottle how much concentrate it holds and to what volume it is topped up.
2. Work out how much base and, if needed, nicotine base to add - the calculator is below.
3. Add the nicotine base, then VG/PG up to the mark.
4. Close the bottle and shake for 1-2 minutes.
5. Let it steep: fruit flavors are ready in a day, desserts and tobaccos in a week.

Calculator for a longfill

The example is a 60 ml bottle holding 12 ml of concentrate, i.e. 20% of the final volume. Enter your volume, the share of concentrate, the strength and the VG/PG ratio - the calculator shows how much of each to add.

Common mistakes

• Topping up by eye. The concentrate is made for a specific volume: too little base makes the taste harsh, too much makes it flat.
• Forgetting the PG in the concentrate. The concentrate is almost all PG, so the finished liquid is thinner than the base. The calculator shows the actual ratio.
• Not steeping. Right after mixing the taste is flat - wait at least a day.
