Tobacco, Caramel, Nut & Vanilla are combined to create the beloved ACRY-4


For DIY Home Mixing

 This is our AC-RY4 Concentrate, designed to replicate our original & legendary “AC-RY4” flavour, when mixed with the users desired ratio of VG/PG (and nicbase if required).

We would suggest between 10% and 25% as a guide percentage to use, but strength of flavour is always at the users preference.

All Alchemists Cupboard Deluxe Concentrates are PG based and intended for the home user.

Please read the mixing guide available here


Amongst most Vapers, the flavour known as RY4 is considered legendary.

It was originally formulated and made by a chemist working for The Ruyan Group in China.

Many stories are repeated about the chemist hiding in a cave somewhere in China with the stolen RY4 recipe tattooed on him.

RY4 became an instant hit, and every other E-Liquid manufacturer and DIY hobbyist set out to re-create this complex E-Liquid.

The great variety of RY4 versions are a result of the many different combinations of the main ingredients:- Tobacco, Caramel & Vanilla, with a few additions.

The AC-RY4 has all the above and more, resulting in a exceptionally smooth vape and flavour hit. It is exactly as The Alchemist imagined when he started experimenting with this.

    If you’re after pleasant tobacco Vape, this is for you. Strong flavour, I use 15% and it’s still quite strong. The slight nutty caramel part is perfectly balanced, but doesn’t detract that this is still essentially a tobacco flavour. The best RY4 of them all.

    First and foremost it’s a lovely tobacco blend, but the nutty sweetness is what makes this juice exceptionally good. The best RY-4 I’ve had to date.

    I have used RY4 for a few years now as my all day vape, perfect replacement for cigarettes, I don’t really like sweet juices. I used to buy AC-RY4 already mixed with nic from Alchemist cupboard but since they stopped selling nic I started to make my own. Easy recipe, 100mls RY4, 100mls 72mg/ml nic, 200mls vg / pg mix of your choice. This gives me 400mls of 18% nic juice that lasts me a very long time ! Excellent service, 1 x week delivery to Australia is outstanding !
