We stock a curated retail collection of RY4 e-liquids for the juice connoisseur

We are a dedicated stockist of RY4 e-liquids and have a multitude of different RY4 vape juices to choose from in store, as well as other variants of this sweet tobacco flavour elixir. The RY4 e-liquids we sell are flavour tested so that each variant passes our selective tastebuds, we don’t sell anything that we won’t vape ourselves and have also tried to be bold with our brand choices to include some more outlandish takes on RY4 that feature different injections of flavour.



RY4 Tobacco E-liquid

RY4 is a term that you’ll frequently run into in vaping circles as it was one of the very first e-liquid flavours created when e-cigarettes began to take off in the late naughties (2000s). This shortened article looks at the description of what an RY4 vape juice flavour tastes like, what the RY4 name means, how it came into meaning and who invented it.


Probably one of the best all-day-vape e-liquids

The RY4 flavour is based on three principal ingredients: Tobacco, Caramel and Vanilla (and a couple of other secret ingredients which the inventor, or his chemist would not name) to create a vape flavour that would never get old, and that could be used as a base to build other flavours upon.

It's also the best crossover vape for new (ex-smokers) vapers transitioning away from tobacco blends over to sweeter food flavour e-liquids that depict fruits or desserts.

This flavour was conceived by Ludo Timmermans and an (al)chemist at the Chang Ning Dekang Biological Technology Company (dekangbio.com) at the invitation of his friend (the boss of Dekang) to visit their laboratory.

RY4 e juice/e-liquid flavour and taste described

Chasing the perfect e-liquid flavour formula

The RY4 recipe came into existence as Ludo tried to recreate the flavours of an analogue cigarette brand that he smoked, encompassing it into an e-liquid form. Thankfully he failed at actually recreating the exact flavour of the cigarette itself, but along the way he found an impressive flavour he wanted even more during the stages of formula experimentation below:

Attempt – 1: Very subtle mixture of tobacco aromas

Attempt – 2: Taste dry tobacco, raw, with no sweet aftertaste

Attempt – 3: Exceptional blend of tobaccos, slightly sweet taste but non descript

Attempt – 4: Tobacco blend with the trends of caramel and vanilla

There was a fifth attempt at creating it by Ludo, but all this told him was that he had gone too far, had gone too sweet and that number 4 was the perfect holy grail of e-liquid flavours.

...The final flavour ended up being called Ruyan Number 4 (apparently named in honour of the original Ruyan electronic cigarette, and the #4 from the number of iterations of recipe attempts) and was subsequently abbreviated down to RY4. There are some disputes/rumours as to whether it was created for Dekang, the Ruyan Group or Ludo himself (where he coincidentally had worked for the Ruyan Group) – either way the flavour he dreamed is now known as RY4. A true ‘elixir’ e-liquid for vaping.

Ultimately Dekang went on to manufacture and distribute the new RY4 e-liquid recipe from 2007 (including to the Ruyan Group, but not exclusively – although anyone else selling it was asked to not to call their variant RY4 which is why you see other names like Riskee Yuice), and it was also produced for Ludo’s new business Janty (now closed – obsolete website here) until May 2010.

Ludo as a heavy smoker knew that the taste he created would make it big in the e-cig world, and it did. The RY4 flavour became an instant hit with early adopters in e-cigarette circles and became well sought after. Since its creation, RY4 has helped many a smoker ditch the evil weed and switch to the e-cigarette.

Unfortunately, in late 2010 the legendary RY4 recipe somehow stopped tasting so ‘epic’ – rumours are that the original ‘holy grail’ recipe was either lost, or the formula was given away and it has now ceased production (the word is that Dekang gave the flavour away, which apparently is typical for the Chinese?!? – and the chemist who helped him has since disappeared with the secrets of the ‘real RY4’).

RY4 is one of the oldest e-liquid flavours in vaping, it has a rich history that will continue to evolve as e-liquid artists & brands are now trying to rediscover the secrets of this classic flavour, or to re-invent it with new improved twists. So much so, that every other e-liquid manufacturer (and DIY hobbyist) has set out to create his complex mythical E-Liquid.

Modern RY4s of today have evolved, and are probably better upgrades rather than just being imitations of the old legendary Ruyan blend, of the same name.

The name Ry4 has now become an umbrella term for the category of e-liquids that incorporate the three ingredients: a delicious combination of rich soft caramel (with hints of brown sugar), inherently sweet vanilla tones, and a light tobacco base (that is usually mild and understated, but sometimes stronger and more up front) that can remind you of those rare occasions when you actually enjoyed smoking an analogue cigarette back in the day.

RY4 is now a very popular e-liquid flavour type. Not surprising as it’s probably one of the best all-day-vapes and is very more’ish. Not too sweet, not too throaty, and a very nice to vape on all day without getting bored of it.

RY4 is based on three principal ingredients: Tobacco, Caramel and Vanilla to create a flavour that never gets old, and is probably one of the best all-day-vape e-liquid flavours as it’s very more’ish.
We love RY4 flavours because they are so damn smooth and subtle. There's something about this flavour profile that really hits the spot.
As virtually all vapers are ex-smokers, we naturally gravitate towards an e-liquid that will give us the same sensations or memories as that of smoking a real cigarette.
RY4 has the same throat hit and tobacco sensation akin to that of our best memory of analog cigarettes, but made smoother, sweeter and healthier in our minds.
The magic of RY4 lies in the quality of the ingredients and how they’re blended. Some RY4s are bright, almost effervescent with a pronounced sparkling high end.
There's hardly a RY4 that doesn't taste great, the subtle but complex combinations of flavours makes an RY4 interesting.
RY4 is one of those blends that has always reminded me of craft beer. Sure, they all have the a similar tobacco/vanilla/caramel flavour, but there are marked differences.
The RY4 E-liquids we sell have be flavour tested so that each variant passes our selective tastebuds, we won’t sell anything that we won’t vape ourselves.
