**Tart Blast (Flavorah) 1% (11-5-23)** -- Out of the gate, this one was Lemons, and it stayed that way to the end of the testers. Gave it some extra time, as I wanted to make sure to get it right. Now, this one could, and would boost up fruits, but going too high, would inject Lemons. NOW, this was NOT a typical Lemon flavor, as it seemed to have a lot of the very bright higher notes, and when finger testing, had an almost lemon oil, fresh from the rhind. I got a fairly even 50/50 natural/artificial split, with the artificial notes being somewhat Lemonhead"-ish. It is, and was billed as an enhancer, which is accurate, and testing it AS a solo can't fully flush out it's effect(s) in mixes. Sweetness was a few ticks below mid-level, and no off-notes could be found. Although Flavorah stated it would boost "fizzyness" that is unclear, but boosting fruits, especially citruses, would be 100% guaranteed. All in, an interesting "enhancer" that solo'd, was a 50/50 mix of natural and artificial lemon top/bright notes, with a genuine lemon/citrus oil undertone. Judging this solely as an "enhancer" I would rate it higher, with the only take-off being the no "fizzy enhancements", BUT, again, this was tested solo. Leaving it at a **9.1/10**."
