The Best RY4 Flavorings

Caramel Vanilla Tobacco

RY4’s are a flavor profile born of vaping. Before then, the RY4 flavor didn’t exist. What is it exactly? Well, it’s part of the Ruyan scale, which measures a specific “tobacco” based on its flavor. Measured from RY1 – RY4 – with the RY4 being the sweetest and containing the most tobacco. In this video, I will run through the most popular RY4’s on the market, and which ones I think are the best.

TFA RY4 Double

This flavoring to me is the standard RY4. It’s what I think of when I think RY4. It’s flavor is a brighter caramel, honey, and butterscotch with very light notes of earthier bakery, or lighter tobacco. I like it around 5 – 8%, but it’s %’s can be scaled quite high.

Recipe Example

JF RY4 Double

This is very similar to TFA’s RY4 Double, except on the darker and deeper side. Where TFA’s is brighter and more focused on the honey, and caramel. This one is more focused on the richer caramel, with heavier bakery and tobacco notes. Use anywhere from 2 – 5%

FA Soho

This isn’t quite an RY4, per se. But its flavor profile matches. To me it’s an earthy bakery with caramel and vanilla notes. Except with FA’s offering, there’s a touch more of a natural flavor to it all. The earthiness is a bit more woody, and a bit more real, making it great for those who don’t want something so sweet. I use this usually around 2 – 3%

DIYFS Holy Vanilla

This is flavoring is a bit more of a one-shot. This is also very different from the others, where this offering has a lot more vanilla. It’s almost like an RY4 Custard. It’s a delicious flavor, but if you’re looking for an RY4 that focuses on the tobacco or bakery, this is not it. I like this at 5 – 6%

FE RY4 Double

This, to me, taste much more like a coffee, or espresso. It also has the same off-notes that are present in coffee flavorings. I do understand why they call it an RY4, as there is a touch of caramel in the cappuccino flavor. But it’s not very accurate.

INW RY4 TDM

This flavoring easily has the most tobacco flavor out of the others. A very natural, wet, tobacco leaf flavor, mixed in with light honey and caramel. What it lacks is that rich caramel note, as well as the bakery note. If you’re looking for a more bright, leafy, tobacco heavy RY4, this is it.
