Posca

[Yehya]

I have been drinking a variation of this daily for a while although more for the health benefits than anything else. I mix about three parts vinegar to one part honey in a thermos and shake it. Each day I mix enough with a bottle of water to taste strong but not so much it gives me heartburn 

Been drinking it long enough to miss it if I skip a day

Very nice. You are not alone in this venture. Mine is different, though... if it can be called posca. I tend to use pomegranate reduction in place of vinegar. I also add sea salt and the rest is water. No real measurements, but I am mindful of the amounts used.
