I mixed a batch of this up about three days ago and managed to last until about an hour ago before I gave in to my primative urges and tried some.
Oh.My.God.
Just as the OP says, i'm getting a smooth coconut taste on the exhale and it's stunning. I haven't tried their actual juice, so I might get some to compare the original against the concentrate.
If it's this good after just three days I can't wait to taste it again in another week or two (I made 3 10ml bottles)
