Using forest fruit as a building block will get you a 'decent at worst' result 90% of the time. With as much as it has going on, I only needed a couple berries to push into a new flavor direction but still keeping the heart of the vape distinctly 'forest fruit'. Wanting to get a little more darkness up front, sweet currant was an easy grab. Blueberry juicy ripe is a flavor that I've beeen digging for awhile and it pairs nicely with the sweet currant. The dragonfruit is used at a 1 percent to add a little background note while also blending this whole thing into a tasty but nondescript berry profile. I like it with a quarter percent sweetener and mix every other 30ml with 1% ws23 but feel free to dress it up how you like.
This can be vaped off the literal shake and you will get a bit currant and blueberry forward vape but delicious none the less, 24 hrs and it starts to meld together.
@ponchponch I use that blueberry because it seems "complete" to me. You can use it as your blueberry note without having to use in a combo of flavors and seemed to blend well with others. With that said though, you could use whatever blueberry you like to fill that role. I personally dont have fa bilberry, but fw blueberry or tfa blueberry extra would def work here. Boysenberry would work as well (and I'll mix it up soon as a sub) but it would change the profile a bit.
