My rum doesn't taste rum. Why?

[Paname]

Hi.

First of all, i apologize for my bad english. I try to do my best to be understanble.

I'm trying to make rum, my recipe are very inspired by hook rum's recipe.
I'm using organic cane molasse (nothing else than black molasse in it) from organic food store (expensive but it's the only form i know it's sold in my country), raw cane sugar, baker yeast, plain tomato paste, lemon juice and spring water.

But my final product doesn't taste and smell like rum i know, from rum i bought at liquor store.
In my country, most of the rum sold are made from fresh cane sugar juice (rhum agricole). I never drunk a white rum made from molasse.

For people who drunk white "rhum agricole", white "molasse" rum and their own white "molasse" rum (hook rum recipe for example), could you tell me if there is a big difference in taste and smell between these different kind of rums?
Because when i smell and taste the rum i made, i recognize nothing from white "rhum agricole" i drink usually.
