Review of Dulce de Leche Flavor-TFA:

I did a taste test in plain iced water with a little monk fruit sweetener and about 4 drops. It was soo bitter, like a 'burnt' flavor, Notes of a caramel coffee kind of thing, it smelled good, like a warm vanilla candle scent, but there's something off putting and very chemical.  I could not imagine what I would use this one for. To be fair, the other flavors I bought were pretty great. Just, not this one. Can't use it unfortunately.
