French roasted coffee has an intense flavor profile. After all, it is roasted almost to the point of burning, (not quite though! Thankfully) and so its deep flavor will be a ‘mouthful’, to say the least.
And check this out, while its dark roast gives it a definite smoky flavor, it also has sweet notes intermingling with that smokiness.
It’s also less acidic than lighter roasts and its strong flavor makes it full-bodied.
