I did the recommended 20% and it seems about 5% too high (almost tooooooo much flavor) but then again - I remember Boba's being bull of flavor.. Try it with the ACV - I haven't even tried it w/o it but I probably should to see if there is a difference.. Considering I haven't vaped Boba's in over 3 years - this is rrrrrrrrreally close and satisfying.. Something feels missing as far as the exact Boba flavor profile but its nothing that I missed enough to not enjoy this as much as Boba's... I want to say its raisin but not sure (and don't care TBH).. Good luck with the ADV - I did a speed steep in the crock pot and something I noticed was when I smelled the bottle at room temp - didn't smell that close to Boba's but when it was hot - it smelled REALLY close.. I'm guessing steeping is essential.
I did 20% and feel it could definitely be lowered a bit. I was thinking about adding graham cracker and marshmallow to mine.
