Comments on the packaging
I'm not going to tell you about my life, but coffee and me, it's an old, long and beautiful story. Also, when I understood that Berk Research was going to release a liquid dedicated to my favorite drink, my blood did only one turn, but a good one! The atypical liquidator, half artisanal, half industrial and totally frappadingue having proven to us many times his great talent for creating authentic juices and devoid of artifice, my curiosity was therefore titillated to the highest point!
The liquid is therefore called “Grain de Folie” and, if you know the Berk Research portrait gallery, just the surname becomes a joke. It is thought out, thoughtful, matured, pampered and cuddled by Berk for months in a padded cell (it seems that it speaks to its juices! 😲) but manufactured by Fuu, which therefore leaves room for a little seriousness in the production chain!
It comes to us in a bottle that can hold 60 ml of liquid and carries 40 ml of overdosed aroma. It is therefore forbidden to consume it as it is. It will have to be lengthened with 20 ml of boosters or neutral base or a clever mix of both to make it ready to vape. You can thus oscillate according to your needs between 0 and 6 mg / ml of nicotine. I advise you to respect a post-mixing maturation time of fifteen days to get the best out of it.
The base obeys a PG / VG ratio of 50/50, house tradition obliges and we are therefore entitled to expect a perfect balance between precision of flavors and volume of vapor. As usual at Berk, there is no sucralose in the aroma. Not more than neotame, aspartame, stevia or hair on Kim Kardashian's butt...
The price is 19.90 €, also balanced, and you can find it in all good physical or online shops, or by default, on the link given a little above. If you want a personal opinion: avoid places where this product does not sell like the plague! Indeed, several stink bomb attacks have hit them recently. The suspect is still running...
Alright, now let’s check out the well-known adage together: “Coffee and addiction, please!”

Comments on the security, legal, health and religious aspects
Made in an outdated motorhome in the desert, à la Walter White, this liquid would not be suitable for consumption other than in an atomizer, which is good since that is what is required of it. It contains amphetamine, cyanide, opium slippers, trinitrotoluene and a little Malox to wash it all down.
More seriously, alas, this liquid corresponds point for point to the most obscure desires of the legislator and displays excellent healthiness. And damn... we can't laugh in peace anymore.

Comments on the packaging
Immaculate white background, almost clinical 🤪. Characters that appear to have been written by Regan McNeil and a photo of Chewbacca's sister-in-law in the header, we are at Berk Research, no problem.
If you have a sense of humor, you'll love it. If you don't have one, what are you guys still doing here?

Comments on the taste of the juice
If you are looking for a gourmet coffee, such as café Liège, macchiato or other tiramisu, please get out of the line and let the others pass. Here, we make REAL coffee. Confirmed vapers know it, it's a particularly difficult aroma to perfectly master, but the Berk Factory seems to have found the right vein!
It's an Arabica. Pure juice. Pungent as it should be but not bitter, so spent following the correct protocol. No milk, wretch, no sugar, stupid! Only the very essence of a good, real, timeless coffee, black like the soul of Ted Bundy.
At the turn of a puff, Grain de Folie barely releases a discreet caramelized note, a diaphanous scent of smoke and sometimes, but very rarely, I want to reassure you, an almost imperceptible touch of vanilla.
The recipe is on a crest line, as is often the case with the manufacturer. We want to laugh a little but, when it comes to taste, there is no question of letting go. You wanted coffee, you got it. Not an ersatz or a pale imitation. Here, authenticity is key. We're not at Starbucks.
If you only have to try one liquid at the end of the year and you like real espresso, this is the one for you.

Comments and recommendations for an optimal tasting
Obviously, it will be necessary to vape this liquid without stopping, from morning to evening. And even at night on a drip. It is perfect on its own but it will perfectly accompany, like its liquid counterpart, a chocolate instant, a cinnamon biscuit, a caramel ice cream and all the espressos in the world.
Given its medium viscosity, you can vape it on all your atomizers, clearo or pods and even put it in your smoke machine, with your disco ball and your projectors, for an evening of the Grand Dukes!

My mood ticket on this juice
There were the Venetians, Voltaire, Luigi Lavazza, Jacques Vabre and George Clooney. Attention, there is a new player in the game. Her name ? Research… Yuck Research!
Top Vapelier, of course, for the fun of the packaging and the seriousness of the taste.
