I've had homemade tonic concentrate on my to-do list for ages. We have the good fortune of having two different friends who make and have gifted us their homemade, and between this plenty and the hassle of needing to round up and order ingredients from multiple sources, my own experiments haven't happened yet. I intend to change that shortly, as our stash is dwindling.
What do you know, what have you learned, and what do you like as far as homemade tonic recipes?
FWIW, I did try John's Premium Tonic Syrup, and while it's good, I didn't find it as good as what we've gotten from friends. Generally speaking though, I like the syurps/concentrates because they have little to no sugar vs. bottled tonics--even the fancy ones--that I find much too sugary.
If anyone can compare and contrast John's to any of the other small batch concentrate brands out there, I'd love to hear that as well.
sip on, friends!
