Make your own e-liquid:



      • A ready-to-use base 
      • One or more concentrated aromas.
      • Optional: an additive (+/- sugar, +/- acid, balancing agent, bonbon effect…).



      • A big 10 ml to 30 ml syringe for the bases
      • A smaller 1 ml one for the aromas 
      • 5 ml/10 ml/30 ml plastic or glass bottles for your formulations
      • Latex gloves
      • Safety goggles



      • Using the syringe or a small dropper, fill an empty bottle with your ready-to-use base (to produce 10 ml of e-liquid: put in 8 ml of base, the remaining +/- 2 ml will be for aromas and additives).
      • As the base contains nicotine, it must be handled with extreme care. We recommend that you wear latex gloves and safety goggles for maximum safety.
      • Shake the bottles of aroma before use.
      • Add a few drops of aroma(s) (See the recommended dosages on the product notice). 
      • Optional: add one or more additives.
      • Shake the bottle well for 10 to 20 seconds and then let it stand for maturation of the aromas.
      • Wash your hands again, clean your material and work surface.
      • Make a note of your recipe for your records or to pass on.



Maturation is a compulsory stage and is the period where the flavours in an e-liquid formulation develop. The aromas do not express themselves immediately in fact and they need: 

      • a minimum maturation period of 15 days if not several weeks for tobacco type aromas.
      • a minimum maturation period of 48h for other types.

For best results, you should shake the flask once formulation is finished and a little each day to diffuse the aroma well.

Please note that the maturation period depends on the base used. The higher the vegetable glycerine content in the base, the longer the maturation period. 



Once the maturation period is finished, your e-liquid is ready to taste. If you find the restitution of flavours too weak, you can add a few drops of aroma and let the formulation stand again for a minimum of 48h. On the other hand, if the liquid is too strong, you can dilute it by adding more base formulation.

      • Too high dosage = need to dilute: add base formulation
      • Too low dosage = need to add a few drops of aroma



      • Start with just one aroma before envisaging mixtures with several aromas. 
      • For additives (optional), stay in a proportion of 1 to 3% of your base formulation liquid + concentrated aroma(s), as the additives are very powerful in general.
      • Label your formulations (aroma(s), dosage, nicotine content, date of production)
      • Prepare your new recipes in 10 ml bottles, but in small 5 ml quantities, to allow for readjustments to the aroma or base.
      • Never skip the maturation stage. To shorten the waiting period, you can add 1 or 2 drops of white vinegar to the formulation or leave the bottle "open" for a few hours a day and shaking it from time to time to encourage oxidation.
