Well, here's my take on a couple of the samples from Molinberry. I tried them in a SmokTech 1.8Ω cartomizer and a Kayfun type device.
Latakia -- really liked this one. It's like the "Smoke and Prunes" (think that's the right name) from another company, but not as intense which I really liked. This one I can vape all day without feeling like my taste buds are getting damaged. On the inhale I get a nice cedar kind of smoke as well as plums or prunes. Delicious. Exhaling I pick up the spices and I'm sorry but I can't discern the separate spices other than to say whoever mixed them knows what they are doing!! I had a little "ash base" I made and mixed the Latakia with it and that took it up another step. I probably wouldn't use it all day long, but what a great change up flavor. So in summary, Nice smokey and aromatic flavor with the fruit and then spices. This one is a keeper for sure. Oh, almost forgot.... ended up using this @ 10%. Any lower and the flavor seemed muted and higher it kind of coated my tongue.
FR-4 -- I may get shot for saying this, but I don't get any "light cigarette" flavor at all. But this was my favorite of all the samples. Again, mixed at 10% -- 10% seems to be the sweet spot for me with all these flavors. The FR-4 tastes like delicate mix of exotic flavors. There is also a nice sweet flavor reminiscent of the old dipped cigars minus the tobacco flavor if that makes any sense at all. I mainly get a very light anisette flavor mixed in with another mystery blend of spices. I was literally scraping the bottom of the bottle to get all of this flavor out to make just a tiny bit more I like it so much. Easily an all day vape for me. I honestly don't know how I would categorize this flavor. Maybe somewhere between dessert and exotic?? I definitely would like more of this to "keep testing"....hint, hint Marcelina (just kidding) .
I know I am not a storied juice tester but what I have written so far is my honest opinion. I'll follow soon with my take on the other 3 flavors. Hope my opinions made at least a little bit of sense......
