Eulen Aroma Ypsilon 4

Eulen Aroma Ypsilon 4: Fruity Concentrate for Your DIY Liquid

Ypsilon 4 from the Eulen Aroma line is a ready-composed aroma concentrate in a handy 10 ml bottle. It delivers a clear, fruity primary note on the inhale that tastes balanced-sweet and requires no additional cooling (no ice) – pure fruit flavour without a menthol aftertaste.

The base of the aroma is 100 % propylene glycol (E1520). This allows the concentrate to dissolve quickly and residue-free in your preferred VG/PG base – whether you use a high VG ratio for DL & Sub-Ohm or a PG-dominant mix for MTL and pod systems. It contains exactly what's on the label: just aroma and PG, no nicotine, no sweeteners like sucralose.

Those who deliberately avoid sucralose will find Eulen Aroma Ypsilon 4 to be significantly gentler on coils. Sweeteners otherwise settle on the cotton quickly and shorten the lifespan of atomiser heads and builds – this aroma stays clean.

How to Mix Eulen Aroma Ypsilon 4 Correctly

For 10 ml of liquid, measure 1 to 1.2 ml of the concentrate – this corresponds to the recommended dosage of 10–12 %. After mixing, shake vigorously and let the liquid steep for 1 to 2 weeks to allow the aroma to fully develop. Suitable for MTL, pod systems, restricted lung hit (RDL), as well as DL and Sub-Ohm – the flavour adapts flexibly to the base and draw technique.
