Duomei  Sour Mango flavour concentrate.
 
Our first impression: very close to a natural Mango not too sweet or honey style like yellow mango Is it sour? we don't think so but it's pretty damn good and tasty .
 
Ok, is it the best mango from our view? it is very hard to judge, to be honest all of Duomei's Mangoes are great and each has different features, it is very hard to choose one of them, we advise you to grab all of them why not? we all have tons of flvaours in our stash so why not have the besties too? try one of their mangoes and you will not be disappointed!
