hmm. I find the drink tastes pleasantly tart, but smooth and deep with the BSM. Maybe you need to a little take more BSM. Or slightly lecc ACV.>> (I wouldn't be inclined personally, to go up and up on the limewater. You may be at as much as you can handle.) I find it (acv) can be a bit acidic, although I like it more in winter) and that lemon has a whole different taste an energy. It tastes rounder, almost.
(no kidding)
I hear you, on the expense, but for me, it's well worth it.
