We did it again! We discovered overseas another brand that tasted our imagination and now … Here we are with the whole line of the tasty e-liquids produced by the Texan brand Double Barrel. The four standard bearers, Oak, Bounty, Royal and Cowboy, have recently joined by the new BaeBacc, a unique flavored tobacco … We’ll talk about it in due time, do not be afraid!


Today we talk about Oak:

A creamy blend of RY4 tobacco eliquid with undertones of caramel, vanilla, and hazelnut.

The Oak bottle is 30 ml amber glass with a childproof cap with a dropper beak tip. The label is very elegant, with a background texture with the wooden axes of a barrel while the texts appear with a classic gold font. The information on the bottle is generic and skinny. As far as the ingredients, the liquid contains propylene glycol, vegetable glycerin and artificial and / or natural concentrate aromas. In addition to the product name, are indicated the composition of the base and the nicotine content. Nothing more than the manufacturer’s master references. This bottle as easy to guess is not TPD ready but, on the manufacturer’s site we have found that Double Barrel products will soon be all TPD compliant.


On the smell on a light alcoholic background, there are pleasing vanilla and caramel notes that seem to be well-mixed with each other. Much lighter and far I perceive light tobacco nuances. My nose perceives them timidly but enough to identify the main features: light and not too sweet. It is a N.E.T. probably built on a classic Blend Burley-Virginia, a blond dry tobacco. The general feelings are good, the overall scent is very clean and natural. No disturbance or interference from artificial smells.

For the vape test, considering that this is a natural flavored tobacco, I set my old and trusted Hobo Customs RDA in single coil and, leaving the atom sufficiently airy, dripping my first drops of Oak. I immediately admire the wide and deep puffs and see an e-liquid in her creamy, particularly voluptuous composure.

Absolutely imperceptible alcohol notes have stepped on to an elegant, creamy texture of caramel and vanilla. The caramel is warm, vigorous and penetrating and emerges brilliantly in inspiration, leaving it to be entrusted with the vanilla the task of adjusting and bringing the heart of the whip to softer and velvety tones. And this vanilla fits very well, as it is beautiful fat and buttery. And tobacco? In this recipe, it is the most discrete ingredient, a N.E.T without aromatic notes of prominent, vaguely woody, simply dry, with the sole purpose of bonding with the creamy and crunchy ingredients.


Blond dry tobacco, vanilla, caramel and hazelnut, a classic tabacco mix that translates into a very simple and well-known acronym in the world of vaping: RY4.

What does RY4 mean? Who has been a vaper for a long time and follows us with assiduousness, knows that we have abundantly spoken of it in many reviews. For the lazy or the novices, you can take a look here.

Oak is a perfect example of an RY4 really well-made and of great value. A mixture of clean and pure caramel and vanilla cream with only slight hints of hazelnut, which tend to be felt better increasing the wattages rise in a kind of roasting effect of the whole blend.


The end result gives us a credible tobacco flavor, of great aromatic stability and very tasty, never surpassing the free sweetening rounds. And even if we are talking about a very common RY4, Double Barrel has the merit of having accomplished it with mastery and meticulousness.

Oak is in my way to see the ideal tobacco to recommend to the vapers streaked by super-creamy liquids that want to approach with curiosity to a tobacco flavor. An all-day lovable and pleasant, never too sweet, with good vapor production, a good aromatic persistence and, last but not least, and so gentle with the degradation of cotton and coil in the atomizer.

Pro: A RY4 N.E.T. based very well done and very gentle with the coil. Load the atom and vape all day without getting bored.

Cons: Not unpublished recipe with a marginal and somewhat anonymous contribution by the tobacco component.
