I buy this brand too and their red dates/longan drink too.
I find it too sweet, not too strong. I do make my own. Just smash a
few knobs of ginger, bring it to boil, throw some brown sugar in
it. But if lazy then, this is the next best thing.
There is another brand though, also product of S'pore but can't
remember the name on top of my head right now.
